Explain in detail that Musk is Tesla’s right-hand man： China executives are ＂excellent＂

Phoenix Network Technology News Beijing time on September 24 th news,Elon Musk is currently running a number of ambitious technology companies by himself.While serving as CEO of Tesla and SpaceX, Neuralink, a brain-computer interface company, and Boring Co, a tunnel excavation company, were also established. Moreover, he is still busy with the lawsuit with Twitter.

Due to the lack of skills, Musk needs to rely on a large team of senior deputies to perform specific affairs. In Tesla, there are now more than 20 people responsible for maintaining Tesla’s business operations.

His direct subordinates often change with the change of the company’s strategy or organizational structure, and occasionally they are "fired on the spot" by the capricious CEO, or voluntarily resign.

Musk

27 senior deputies

According to the data summarized by foreign media, as of September 2022, Musk had 27 direct subordinates in Tesla. These data come from interviews with Tesla’s current and recent employees, LinkedIn profile, Tesla’s internal and public records, and may not include all those who report to him.

Musk’s direct subordinates are mainly concentrated in the United States, and more than 90% are men.Although he has moved Tesla’s headquarters from California to Texas, about half of his direct subordinates (14 people) remain in California. There are only 7 people in Texas, accounting for 22%.

These include Zachary Kirkhorn, CFO of Tesla, Allie Arebalo, Director of Human Resources, Luo Shang Thomas, Vice President of Global Supply Chain Management, Omead Afshar, Head of Texas Factory, David Lau, Vice President of Automotive Software, and Pete Bannon, Vice President of Hardware Design Engineering.

The task is arduous

As Tesla strives to put the new factories in Austin, Texas and Glenhead, Germany into full production and make progress on many other goals, Musk will need to rely on these senior deputies.

Musk has told shareholders and fans that Tesla will "solve the problem of fully autonomous driving (FSD)" this year., improve car service and maintenance, and start delivering Cybertruck pickup trucks in mid-2023.

He also said that Tesla will strengthen its battery manufacturing capacity, with the goal of producing its own 4680 battery with a capacity of 100 GWh this year, which is enough to power more than 1 million Tesla cars.

Moreover, Musk’s direct subordinates also need to lay off employees in the uncertain economic situation recently. Musk suddenly announced a large number of layoffs at the end of May this year, when Tesla faced a challenging second quarter, just as the Russian-Ukrainian war broke out and the epidemic continued.

In June this year, Tesla closed the entire Autopilot office in san mateo, California, and fired at least some employees..

These employees were previously approved to work remotely, but did not agree with Musk’s order to work at least 40 hours a week in Tesla’s office.In June this year, Musk mentioned in an email to Tesla employees that he "felt very bad" about the economy.

China executives

Three of Musk’s direct subordinates work outside the United States, and one of them is Zhu Xiaotong, global vice president of Tesla and president of Greater China.

Zhu Xiaotong joined Tesla in April 2014 as the project director of Tesla China Super Charging Station. In December of the same year, he took over as Tesla’s global vice president and president of China. In 2018, he was responsible for the construction and operation of Tesla’s Shanghai factory, and in 2019, he was promoted to president of Greater China.

One of Tesla’s main businesses in China is the Shanghai Superfactory, which not only meets the demand of China market, but also becomes an export hub.

According to the data released by the China Ride Association, in August this year, Tesla sold 76,965 vehicles in wholesale, 42,463 in export and 34,502 in domestic retail. From January to August this year, Tesla has delivered 399,939 vehicles, which is only over 80,000 vehicles short of the 484,130 vehicles delivered in 2021, including nearly 160,000 vehicles exported and over 240,000 vehicles delivered domestically.

During the epidemic, the production of Tesla’s Shanghai factory faced severe challenges. According to people familiar with the matter, Zhu Xiaotong has been living in the Shanghai Superfactory since March 28th, and is responsible for supervising and ensuring the operation of the factory.

Musk has repeatedly praised the Shanghai factory and thought that the Shanghai super factory is difficult to be surpassed."I must admit that our Shanghai team is really excellent." He said.

Musk is a workaholic, likes to work overtime, and once slept in the factory.Therefore, he praised the diligence of China people. "There are many very talented and hardworking people in China who firmly believe in manufacturing. They not only stay up late, but also work diligently at three in the morning, and even don’t leave the factory at all. Americans try not to go to work. " Musk said this in May this year.

Tesla Shanghai factory

Recently, Tesla’s Shanghai factory has completed the expansion work. Tesla Giga Shanghai (Phase I) Phase II production line optimization project was completed on September 1st and started debugging. The expected acceptance period is from September 1st to November 30th.

The total investment of the project is as high as 1.2 billion yuan, which is an expansion in Tesla’s existing factory, mainly by increasing the production tempo to expand the production capacity. The EIA report released in November last year showed that the production line optimization projects were mainly the expansion of stamping workshop, body workshop, painting workshop, assembly workshop and logistics operation center.

There are quite a few resignations.

Although Andrej Capassi, senior director of artificial intelligence at Tesla, was not among those laid off or fired by Musk, he officially announced his resignation from Tesla in July. Ashok Elluswamy, the head of Autopilot, reports directly to Musk for the time being.

According to internal documents, other direct subordinates of Musk who left Tesla in 2022 include Chris Lister, former vice president of Nevada Super Factory, and Jean Frazier, senior director of employee relations at Tesla.

David Searle, the former head of Tesla’s legal department, still works in the company, but insiders said that they expect Searle to leave in the next few months because he previously managed more than a dozen employees, but now there is only one direct subordinate on the internal organization chart.

According to public and internal records, Dinna Eskin, senior legal director of Tesla, is now the manager of the company’s legal department, and is actually the company’s general counsel. Since the end of 2019, Tesla has not officially hired a person with the title of general counsel. (Author/Xiao Yu)

Behind Changan Qiyuan E07 is Unicom’s C2M overall solution innovation

Recently, the world’s first smart variable new car based on the SDA platform, Changan Qiyuan E07, was unveiled at the Changan Automotive Digital Intelligence Factory. This digital intelligence factory focuses on the production of intelligent networked new energy vehicles and is the unveiling unit of the "National Intelligent Manufacturing Pilot Demonstration Factory".

"Black Light Factory" is the most concrete description of advanced intelligent manufacturing production spaces such as Changan Automobile Digital Intelligence Factory. Tens of thousands of intelligent equipment perform their duties in the factory, more than 800 robots are lined up, more than 500 AGVs shuttle between them, and more than 100 fully intelligent AGV islands replace the original fixed floor chain transmission, which greatly reduces manual participation and increases production efficiency by 20%.

The reporter also learned that the Changan Automobile Digital Intelligence Factory has adopted an innovative software automatic packaging and testing process, which has greatly reduced the data filling time and improved the efficiency of cloud-based electrical inspection by nearly 100%. The AI manufacturing database has become the first factory in the industry to generate more than 28T of manufacturing data per year.

The first 100% to the machine station, the first 100% to the station, the first independent controllable and 5G-compatible industrial control Internet of Things… The application of 5G technology in Changan Automotive Digital Intelligence Factory has set a number of industry firsts. "This is due to China Unicom’s Legion innovation model." Zhou Hua, general manager of China Unicom’s 5G Fusion Innovation Center and Automobile Manufacturing Legion, which undertakes the Changan Automotive Digital Intelligence Factory solution, said.

Focusing on the C2M model

Meet personalized market demand

Data standards are not uniform, it is difficult to share and integrate, limiting real-time information transmission and business collaboration, business complexity lacks unified management, business collaborative efficiency is low, and it cannot adapt to new market demands… In recent years, in the face of the new consumption patterns of "customer engagement manufacturing", "user-defined car" and "user experience car building", the lack of interoperability between the original systems of traditional automobile OEMs, inconsistent standards, and difficult data sharing have become increasingly prominent.

In response to this problem, after nearly two years of practice and polishing, China Unicom Automobile Manufacturing Corps has given its own answer. On July 19, the Shanghai World Expo Center officially released the China Unicom Automotive Industry C2M Overall Solution (hereinafter referred to as the "Solution") at the "Innovation Achievement Release and Partner Conference" jointly organized by China Unicom Research Institute and China Unicom Automobile Manufacturing Corps.

C2M stands for "Consumers participate in manufacturing, organize production according to orders, and provide delivery response and delivery control according to orders". The core of the C2M solution is the Qingtian unified industrial control platform, which provides data standards, application standards, and information interaction standards, and integrates basic applications such as planning, execution, logistics, and quality. Develop enhanced applications that are compatible with C2M, such as logistics enhancements such as warehouse management, manufacturing execution enhancements such as order insertion management, and program enhancements such as dynamic sequencing, so as to achieve data sharing, instruction accessibility, and business implementation coordination, and ultimately realize delivery visibility.

It is understood that the program is based on the practice of multiple projects such as Changan Automobile, relying on advanced Internet of Things and data modeling technologies to provide enterprises with fully connected visual management to ensure the transparency of the whole process, so as to improve enterprise management efficiency and decision-making ability, and achieve the purpose of reducing costs and increasing efficiency.

Leverage the advantages of Unicom integration

Supporting C2M solutions

China Unicom’s C2M solution involves multiple levels of progressive change such as 5G network replacement, edge application reconstruction, data empowerment, and platform reconstruction. The Legion innovation model of Unicom’s integrated capability aggregation plays a crucial role in it.

The Automobile Manufacturing Corps is one of the first vertical innovation units established by China Unicom for the automobile manufacturing industry. It integrates the group’s technological accumulation and innovation resources, carries out technological innovation for the automobile manufacturing industry, overcomes the technical difficulties in the industry, and practices the responsibility of the central enterprise to serve the national strategy.

The Automobile Manufacturing Corps gives full play to Unicom’s cloud network resources and technological endowments, provides 5G-based "cloud network edge" new infrastructure, and supports "visual, manageable, dimensional, and configurable" platform support. It solves the problems of fragmentation, black box, and inefficiency in the original infrastructure, and meets the industrial production requirements such as data not coming out of the network, uninterrupted business, and unified control plane, providing reliable and credible network protection for C2M.

At the same time, the Automobile Manufacturing Corps provides standardized and process-oriented business modeling around business scenarios, ensuring consistent modeling between different business units, providing business-level API calls for upper-level applications, enabling business connection, service sharing, and capability precipitation. It can quickly track positioning and complete iterations when requirements change, laying the foundation for C2M to quickly respond to business requirements.

Based on the accumulation of China Unicom technology, combined with the characteristics of the automotive industry, the Automobile Manufacturing Corps has created a data management system, providing data collection, storage, analysis, and governance capabilities, integrating global data, breaking down barriers, forming unified sources and unified standards of data and services, and providing high-quality data protection for C2M.

Faced with the "chimney-like" problem in the traditional production and manufacturing process, the Automobile Manufacturing Corps combines industrial control requirements, supports data collection and control command integration by innovatively, and uses its pioneering "factory-workshop-production-station-station" five-level space modeling technology to simplify the architecture, support business two-way forwarding, instructions can go directly to the station and other minimum execution units, and the performance exceeds 30% of congeneric products, providing C2M with the ability to direct instructions.

Promote industrial chain collaboration

Empowering traditional manufacturing to digitally upgrade

The C2M solution not only reshaped the production scene in the factory, but also strengthened the linkage and collaboration outside the factory, promoting the quality of the industrial chain collaboration to a new level.

The solution can not only achieve data sharing and real-time updates with other information systems such as supply chain management systems, but also enable upstream and downstream enterprises in the industrial chain to understand each other’s production status and demand information in real time, break the information island, improve information transparency, form more accurate co-frequency collaboration, and improve the collaborative efficiency of the supply chain.

The C2M solution can also integrate multi-dimensional factors such as market demand, production capacity, material inventory, and material supply planning, and efficiently and reasonably arrange production plans. Under the premise of meeting the order delivery time, it takes into account levelized production, which is not only conducive to the stability of the factory production rhythm, but also conducive to maintaining the stability of the supply chain.

In the face of emergencies, C2M solutions can quickly simulate and analyze, evaluate risks, and this ability to accurately calculate and respond quickly can assist factories in making overall plans, making quick decisions, and minimizing impact. By collecting and analyzing the big data generated by the interaction between the production scheduling system and the supply chain management system, enterprises can continuously optimize the supply chain layout, improve the flexibility and adaptability of the supply chain, and help upstream and downstream enterprises in the industrial chain to better cope with market changes and challenges.

This time, the C2M overall solution released by China Unicom Automobile Manufacturing Corps takes the order as the main line and takes the delivery as the goal, which can quickly realize the delivery response and delivery control, and newly defines the new standard of mixed-line production and flexible production. It will inject new impetus into the digital transformation of traditional industries, which is not only suitable for the construction of new factories, but also for the transformation of old factories.

Which is better, Xingyue L or Link 01？

Thanks for clickingpay close attentionYou can receive all kinds of content about cars for free in the future.

L and are both domestic cars, and they are both "Hua Dan" cars. The back of this palm is full of meat, no matter which one is praised, it is a kind of harm to the other. Therefore, only by comparing the advantages and disadvantages of these two cars in detail can we find out which car is more valuable. As the saying goes, "There is no shortage of gold, no one is perfect", and so is the car.

Reality always makes us feel "cruel" powerless, and we have no choice but to make one choice: I personally suggest choosing. It’s more cost-effective than ours, and I have my reasons for saying so.

Xingyue L chooses 2021 2.0TD DCT EVO two-wheel drive distinguished model, and Lingke 01 chooses 2021 2.0TD two-wheel drive Pro. The first choice is that these two cars are both equipped with 2.0T, followed by compact cars.

Next, I will analyze and compare the car from the following five aspects. With the comparison, it is clear at a glance which car is more suitable. As the saying goes, there is no harm without comparison.

The listing time is July 2021, and the listing time of Link 01 is December 2020. Although they are all 2021 models, the gap between the time of listing of the two cars is full for half a year, and the gap is still a bit large.

The official guide price is 155,200 yuan, and the official guide price of Link 01 is 179,800 yuan. They are all 2.0T compact SUVs, but the price difference is nearly 30,000 yuan. If you refuel this 30,000 yuan, you can basically run more than 40,000 kilometers and nearly 50,000 kilometers per kilometer according to 0.6 yuan, which is not a small sum.

The comparison result of this first item is that Geely Xing Yue L is obviously superior to Link 01.

andLectra 01 is equipped with 2.0T turbocharged engines, with a maximum power of 160kw and a maximum horsepower of 218 HP L4,325 N m.. CarriedThe engine model isJLH-4G20TDJ, the technical parameters are all the same. It is true that the same engine is matched to different models, and the price will rise.

The only difference is the gearbox. Geely-carriedIt’s 7th gear.Wet (DCT), andThe Lectra 01 is equipped with an 8-speed (AT) gearbox. Generally speaking, wet dual clutch may not be as durable as AT gearbox, but it has higher transmission efficiency and better fuel economy. For a family car, dual clutch is absolutely no problem, and it is still (DCT), so there is no need to worry too much.

In the second comparison, the engine technical parameters of the two cars are exactly the same, the only difference is the gearbox, and the wet dual clutch has obvious advantages over AT.

Body sizeLong x wide x highrespectively are4770x1895x1689mm, Lectra 01Body sizeLong x wide x highrespectively are4549x1860x1689mm。 It is also a compact SUV, but the body of the Xingyue L is longer than that of the Lectra 01. Although it is not many, it is always so big. Judging from the configuration of the chassis, Linke 01 is not very dominant.

And the driving methods of these two cars areFront drive, and the suspension system is the same. The front suspension form is multi-link independent suspension.

The steering system is the same, all of them, and the body structure is load-bearing. Even the configuration of the tires is the same. The wheel hub size configuration of the front and rear tires is 235/50 R19.typeelectrical parking brake.

From the analysis of the chassis configuration, the chassis of these two cars are exactly the same, and it may be more sporty than the adjustment of the chassis.

Through the comparison of the third item, it is found that the body length of Xingyue L is longer. The chassis suspension configurations of Xingyue L and Link 01 are exactly the same, so this one is more advantageous.

Active security configuration this block,andThe configurations of the two cars are almost identical. ABS anti-lock braking (EBD/CBC, etc.), brake assist (EBA/BA, etc.), traction control (TCS/ASR, etc.) and body stability system (ESP/DSC, etc.) are all standard.

Active safety early warning system,Lane departure warning, front collision warning, active braking, and road traffic sign recognition are also standard.

The configuration of Linke 01 is more than that of Xingyue L:Rear traffic warning, reversing vehicle side warning,Parallel line assistance, fatigue driving tips.

The passive security configuration is the same as that of. Passive safety configuration mainly includes: in front of the airbag in the main driver’s seat and the co-pilot’s seat, the front rowSide airbag,, (Tire pressure display),Child seat interface ().

Through the comparison of active safety configuration, LEEK 01 has four more configurations than Xingyue L. These configurations can make the driving journey safer, so LEEK 01 configuration is really rich.

andThe common configuration of the Lexus 01 cars:Driving assistance reversing image and 360 panoramic image, constant speed cruise, adaptive cruise, full speed adaptive cruise, (AUTOHOLD), uphill assist (HAC), rear parking radar, engine start-stop technology,L2 levelAuxiliary driving level.

ofThere are four driving modes. respectively areSports, snow, standard comfort;Lingke 01ofThe choice of driving mode is divided into three modes, namely:Sports, snow, standard comfort,There is one less snow mode than the star crossing L.

Xingyue L has the configuration that Linke 01 does not have:Front parking radar,540 panoramic image,The steep slope descends gently (). Is there a configuration for:Car side blind spot image.

Through the comparison of the fifth item, it is found that the Lectra 01 is even better than the Star Yue L. I really don’t know what to say. I didn’t compare it in detail before, so I always feel that the Lectra configuration is rich, which is really a bit disappointing.

No contrast, no harm. Through the comparison of the above five items, a problem is fully explained. The high price is not necessarily affordable, and the whole department is tens of thousands higher than the price. So … I think it’s more affordable. If I choose between two cars, I’ll choose.

Wu Jing invited Jackie Chan to film! ＂Dragon Horse Spirit＂ reveals new feature footage

1905 movie network news The movie starring the screenwriter, director,,, and lead is being released. So far, the movie has won the single-day box office championship for 11 consecutive days, with a total box office 160 million. In the movie, Jackie Chan’s flexible and changeable action comedy style is still light and humorous. In addition, what is more moving and unforgettable is Jackie Chan’s sincere tribute to the spirit of the Dragon Tiger martial artist. The film not only reviews the many wonderful moments in Jackie Chan’s 60 years of film, but also dedicates it to every Dragon Tiger martial artist who "works hard to fight".

On April 18, the film released a clip of "Tribute to the Dragon and Tiger Martial Artist". Yuan Wei, a junior action actor played by Jackie Chan, invited Lao Luo, an outdated martial artist played by Jackie Chan, to shoot a scene and pay tribute to the spirit of the Dragon and Tiger Martial Artist. Lao Luo, who has been away from the studio for many years, still insists on the spirit of the Dragon and Tiger Martial Artist’s practice and requires "real fight and real fall" in the face of emerging visual effects technology. Under Yuan Wei’s dissuasion, Lao Luo’s sentence "Don’t fall, what will the audience watch" is very emotional. Jackie Chan and Wu Jing, representatives of two generations of action movies, joined hands to offer this tribute scene, which made many audiences call "profound significance".

Jackie Chan and Wu Jing join forces to pay tribute to the Dragon and Tiger martial artist

The collision of the two generations of martial arts concepts is touching

"Dragon and Tiger Martial Artist, never say no". In the movie, Jackie Chan’s role as Lao Luo has adhered to the spirit of Dragon and Tiger Martial Artist for decades. No matter how dangerous the jump, no matter how difficult the action is, he will do his best to complete it. "They are very simple, action, jump, hospital", just three words, not only summarize the professional characteristics of Dragon and Tiger Martial Artist, but also almost outline Jackie Chan’s film career. Jackie Chan’s true character as Dragon and Tiger Martial Artist brought the audience bluntly said that "some empathy does not need to be played, it is the truth that comes from the heart".

Among them, the tribute scene completed by Jackie Chan, Wu Jing, and Tang Jili, three representatives of Chinese action movies, is particularly meaningful. When the traditional concept of real combat meets the upgrade and update of emerging technologies, Lao Luo, who does not understand visual effects, insists on "tribute, come true", while Yuan Wei said that "tribute is not fatal". The concept collision of the two generations of dragon and tiger martial artists deeply touched many audiences. "This scene is like the intersection of the silent film era and the sound film era in the history of film, and both sides have their own attitudes and demeanors."

Jackie Chan is no longer an "invincible" character

"Easy to jump down, hard to walk down" makes people cry

Jackie Chan and Wu Jing in the opposite scene, there is a line that left a deep impression on people. "It’s easy to jump down, but difficult to walk down." This sentence comes from Jackie Chan’s real experience as a dragon and tiger martial artist. Director Yang Zi specially put this sentence in the dialogue between Jackie Chan and Wu Jing, and Jackie Chan, who is nearly 70 years old, also gave the best interpretation of this sentence.

At the end of the three-person tribute scene, Jackie Chan’s role as Lao Luo made a decision that surprised the audience. This time, Jackie Chan no longer "jumped down" fearlessly, but let go of the so-called dignity of the dragon and tiger martial artist and "walked down" steadily. This choice is both sighing and touching. Some viewers said, "I will be amazed by this toughness, even if the tough guy who has jumped all his life did not jump down this time, but walked down steadily. The toughness in the blood of the bones cannot be worn down by time, let alone fade."

There are only five countries in the world that can build aero-engines. How can China achieve ＂parallel running＂？

　　Cartography: Zhang Fangman

　　In the vast desert, soldiers were stationed on the battlefield. At the grand military parade held at the Zhu Rihe Joint Training Base not long ago, nearly 600 sets of engines, including turbofans, turbojets, turboshafts and turboprops, two types of auxiliary power devices and two types of transmission systems developed and produced by China Aviation Engine Group participated in the review.

　　The collective appearance of the "heart" of these aviation equipment is inspiring. At present, seven series of aero-engines, auxiliary power devices and transmission systems have been widely installed on various military aircraft and helicopters in China. More people are concerned, when will China’s independently developed large aircraft be able to use the independently developed "China Heart"? What are the breakthroughs and difficulties in the development of aero-engines in China? With these questions, the reporter conducted an interview.

　　How is the development going?

　　Improve manufacturing efficiency and strive to achieve "parallel running" in about 20 years.

　　Aero-engines play a decisive role in the whole aviation industry, are the "heart" of aviation weapons and equipment to ensure national security and show the status of a powerful country, and are also an important driving force for the development of civil aviation. Moreover, because of the long industrial chain involved and wide coverage, they have a huge driving effect and industrial radiation effect on the development of basic industries and science and technology.

　　Different from previous years, the aero-engine development has been done quietly. At present, the "two engines" project of aero-engine and gas turbine has been included in the 100 major projects and projects planned to be implemented in China in the "Thirteenth Five-Year Plan" and ranked first. It is imperative to develop China’s own aero-engine. On August 28th last year, China Aviation Engine Group, which was jointly funded by the State Council, Beijing Municipal People’s Government, aviation industry corporation of china and China Commercial Aircraft Co., Ltd., came into being, raising the innovation and development of aviation engines to the national will.

　　What progress has been made in aero-engine development in the past year? The reporter learned that in the first half of 2017, the delivery rate of new aero-engines in China increased significantly, which was 8 percentage points higher than that in the first half of last year. When the output of a key model product increased by 34%, the year-on-year product delivery rate increased by 10 percentage points.

　　In addition to the improvement of manufacturing efficiency, the reliability and quality of aero-engine products have also been steadily improved. Li Ping, director of the Production and Supply Chain Office of China Hangfa Production Department, said: "At present, the product field integrity rate is above 90%."

　　At present, the scientific research tasks of China Hangfa are full: there are several engines, auxiliary power units and gas turbines.

　　Dry aero-engines, when can China "run" or even "lead" with the world advanced level? It is understood that the countries that can build aero-engines in the world are the five permanent members of the UN Security Council. Although China ranks among them, its overall manufacturing level is relatively backward. "Strive to achieve it in about 20 years ‘ Run side by side ’ 。” Cao Jianguo, Party Secretary and Chairman of China Hangfa, explained that everything is difficult at the beginning, and so is the engine. We must finish one or two or three models and go through a complete R&D process to form a complete system of design, manufacturing, testing and talent team, and then develop new models. There is a foundation. "The products independently developed by the first generation may not be advanced, but we will continue to work on the second and third generations, or we may become advanced, increasing with generations.

　　What is the difficulty in current development?

　　The biggest shortcoming is the engine design, and the magic weapon for winning is the "national system"

　　According to statistics, it takes more than 20 years to develop a new type of trans-generation aero-engine, which is twice as long as that of the same generation aircraft. It can be said that it is the most complex and multidisciplinary engineering machinery system in the world today, and it is known as "the pearl on the crown of modern industry". Picking the pearl is extremely difficult.

　　First of all, the aero-engine should meet many demanding and contradictory requirements: it should not only work under the harsh conditions of high temperature, high pressure, high speed and high load, but also meet the requirements of large thrust, light weight, high reliability, good safety, long life, low fuel consumption, low noise and low development and maintenance costs. For example, at present, the average on-board life of civil aviation engines should reach more than 20,000 hours, and if they fly for 6 hours every day, they can be used for 10 years.

　　Secondly, the operating space of aero-engine is narrow and the operating environment is harsh, which puts forward higher requirements for design, manufacture and test. A turbofan engine for supersonic fighters is generally only about 1 meter in diameter and 4 meters in length. Such a small cylindrical object has to be stuffed into more than ten stages of fans, compressors, turbines, combustion chambers, afterburner and other components. What’s more serious is that the temperature of the engine combustion chamber and turbine is very high, reaching 1600— At 1700 degrees Celsius, the temperature in the afterburner is as high as 1800— 1900 degrees Celsius, while the highest tolerance temperature of superalloy materials at present is only 1100 degrees Celsius. Therefore, it is necessary to adopt a complex cooling system in the engine and set a labyrinth-like cooling channel.

　　Great technical difficulty also brings huge investment demand. The development cost of a large and medium-sized advanced engine is 2 billion-— 3 billion dollars, more advanced up to 5 billion dollars.

　　Among all the difficulties, where is the biggest shortcoming?

　　"The biggest shortcoming is design." Yin Zeyong, director of China Aerospace Science and Technology Committee and academician of China Academy of Engineering, said frankly that we often say that aero-engines have a long development cycle and large capital investment because they are not only designed and manufactured, but also tested and flown. But only by strengthening the design can we reduce "experiments — Modify the design — Remanufacturing — In the process of trial and error, the backward design ability is the main factor restricting the development of aero-engines in China, which prolongs the research and development cycle.

　　Lack of standards and accumulation is also a big shortcoming. "To build an aero-engine, in addition to the craftsman spirit, there must be a set of standardized design criteria." Yin Zeyong said that the parts that can be made by masters cannot be made by ordinary employees, and the technical reliability is weak. Wang Yingjie, director of the Management Innovation Division of the Quality and Technology Department of the Group, said that the core secret of the world’s advanced engine manufacturers is hundreds of sets of design and manufacturing guidelines. They have accumulated a set of standard systems with years of R&D and manufacturing experience. "In this respect, we still have a big gap."

　　Make up the short board, and the airman is very confident. In their view, the magic weapon to win is the "national system" and the development mechanism of "small core and big cooperation". "China Hangfa is a state-owned super-large enterprise managed by the central government and the only aero-engine development enterprise in China. Its birth itself shows that it is necessary to engage in aero-engines with the power of the whole country." Luo Ronghuai, deputy secretary and general manager of China Hangfa Party Group, said that the state has provided a strong institutional mechanism and financial guarantee for the development of Hangfa industry. "Relevant enterprises have given their full support, and some central enterprises have produced special steel products for us, but the demand is very small, and losing money also supports us." "Industry-University-Research has close cooperation, and our enterprises have established common basic research platforms with universities and Chinese Academy of Sciences to carry out technical research and frontier technology exploration" … …

　　How to climb the hill in the future

　　Information technology means grasping design, and basically establishing an aero-engine R&D system at the end of the "Thirteenth Five-Year Plan"

　　What should China aero-engine do in the future?

　　"At present, the first thing to grasp should be design, otherwise it will be difficult to catch up with the world advanced level." Yin Zeyong said.

　　To do a good job in design, we should not only establish standards and solidification processes, but also make good use of information means. Yin Zeyong, for example, used computers to realize three-dimensional design drawings in the design process; The simulation link should be simulated by using three-dimensional information platform, and the design scheme should be simulated and installed in the computer to see if there is interference between the systems and the assembly sequence is correct; In the manufacturing process, the three-dimensional information of the engine should be transmitted to the factory, and the workshop workers use the three-dimensional model to directly manufacture and process.

　　From the top-level design, China will basically establish an aero-engine R&D system at the end of the 13th Five-Year Plan. Wang Yingjie introduced that China Hangfa is building a complete set of operation management system, including product research and development, manufacturing, supplier management and service guarantee, in which product research and development system is at the core, and independent research and development and manufacturing criteria should be accumulated through system construction in the future.

　　"This system is currently ‘ Bones ’ It’s put up, but it needs to be full ‘ Flesh and blood ’ 。” Wang Yingjie said. For example, the product development stage should provide a technical definition for the development of the whole engine life cycle; In the manufacturing process, the application of advanced management methods such as lean manufacturing and intelligent manufacturing should be realized; Supplier management should not only abide by the rules of market economy, but also strengthen macro-control at the group level; The service guarantee link must not only meet the use demand of weapons and equipment, but also realize the value-added service.

　　At the same time, China Hangfa will strengthen the independent research and development of civil engines that started late, and strive to make civil aircraft such as C919 use "China Heart" as soon as possible.

　　Since 2017, China Hangfa has implemented the "casting heart" project in the whole group. Heart, not only represents the engine is the heart of aviation power, but also represents the concerted efforts of aviation developers. The hard power of the former cannot be separated from the soft power of the latter. Chang Longshu, Party Construction Department of China Aviation Development Party Group Work Department, said that the improvement of new aircraft delivery rate and the shortening of manufacturing cycle can not be separated from the "casting heart" project that gathers wisdom and strength, and will keep in mind the mission and wholeheartedly support the "China heart" of aviation power in the future.

Ramos’s untimely post-match remarks angered the fans (translated from Corriere dello Sport)

After losing to Bayern Munich, Paris Saint-Germain once again fell to the last 16 of the Champions League. This is undoubtedly a heavy mental blow to a club that is determined to be crowned king of Europe. Although the team has a top player like sergio ramos, who has won the Champions League four times, his great experience in the Champions League seems to have brought no effect to the team. The Spanish defender also expressed his disappointment with the team after the game.

The former Real Madrid defender said on his Instagram: "Like your fans, we are deeply disappointed with the result. The team has not yet won the Champions League, and we are still immature in how to deal with the key details. Unfortunately, we failed to achieve an important goal. Although it is very painful, the champion teams all grow up from failure and adversity. We will come back! "

Ps: Ramos is actually telling the truth. Paris Saint-Germain still has many problems and does not have the strength to win the championship for the time being. But after all, the team spent so much money to buy so many stars, but the Champions League record failed to meet expectations, which made many fans psychologically uncomfortable and it was understandable to scold him. In other words, this year’s luck in Paris is really bad. In the group stage, we met Benfica (super this year) and Juventus. After the second qualifying in the group, we drew one of the strongest Bayern.
