After getting rid of the situation of Alice's electronic research laboratory, Zhang Lan, Xiao Chenxi, and Alice went to Alice Composite Materials Research Institute again for a walk.

Zhang Lan is very proud of the research results of the entire Composite Materials Research Institute in various new composite materials, especially in aviation composite materials: although the Composite Materials Research Institute was established in mid-1994, it has only been three and a half years since it was fully completed. However, in the past three and a half years, Alice Group has dug up all those who do have real materials in various state-owned materials research institutes, but are not reused and depressed because of various shortcomings of various state-owned scientific research units or personal personality problems.

The leaders of those units who were poached were also happy: poaching people? No way! Definitely not! Absolutely not! What the? Want to get a prick on the head? Well, this is good, no problem, you all take it away.

So after the Alice Group left, the leader of the poached unit smiled at an envelope on his desk: it contained a deposit slip with a large amount.

Maybe it's because the management of the Alice Group Comprehensive Applied Science and Technology Research Institute is not like their previous unit has so many shortcomings, or maybe the management system of Alice Group in scientific research management is very suitable for their talents. Many people have become the pillars of the composite materials research branch of the Alice Comprehensive Institute of Applied Science and Technology. \\\\

In the eyes of these poached guys, working at Alice Group may be the best place to show their talents: as long as you have real skills, you can be reused; Maybe it's because there's not so much intrigue here, as long as you can complete the task, what should be yours is yours. How far have you done and what kind of treatment you will enjoy. After the research results you have obtained are used by the company, according to the degree of application of the group, the corresponding dividend ratio will be given to you, which has become clearly written in the regulations; Don't worry about being ostracized. As long as you feel that you have been treated unfairly, you can immediately report to the general manager of the group, and the group headquarters will immediately verify this matter. No matter what job you have been doing before, or what position you are in, you will be an assistant to the general researcher, and the second time, you will leave directly.

With such a strict system, no one wants to have trouble with their wallets, and the difference between an ordinary researcher's assistant and a project researcher is absolutely unimaginable. Nature. Naturally, no one will do such a risky thing as crowding out peers.

And that's not the most important thing. The most important thing, and the most appealing thing for these guys, is if you are interested in a research project. As long as the feasibility report of the project, the future use of the product, and the possible performance indicators are made, as long as they are evaluated by a special research and evaluation team of the group. As soon as you decide that the research plan is feasible, the institute will grant you a grant immediately. You can immediately engage in the research you like, and even if you do it, the research results may be used in a very narrow range in the future.

Being able to do what you love most is what these guys love the most. This kind of treatment can not be enjoyed in state-owned scientific research units, well, for Zhang Lan, these research results are his company's technical reserves, and he may not be able to use them one day in the future?

The results of the Composite Materials Research Branch of Alice Institute of Comprehensive Applied Science and Technology allowed Zhang Lan to see the industrial material foundation of aircraft manufacturing in the future: these new materials are the foundation for aircraft to fly. \\/\

For the fuselage of an aircraft, it is nothing more than high-performance aviation aluminum, in order to reduce the weight of the fuselage of the aircraft as much as possible, and go to a relatively perfect balance point before weight and cost, most of the current aircraft fuselage is made of high-strength aviation-grade aluminum alloy materials.

The task of research on aviation-grade aluminum falls on the shoulders of the Metal Materials Research Center of Alice Comprehensive and Comprehensive Applied Science and Technology Research Institute. This metal research institute, which was originally jointly established by Alice (China) Group and the Institute of Metal Research of the Chinese Academy of Sciences, has been upgraded from the original Institute of Metal Materials to the Alice Metal Materials Research Center, and has now completely become a subordinate institution of the Comprehensive Applied Science and Technology Research Institute of Alice Group.

Aviation aluminum has extremely high requirements for the performance and quality of aluminum, and must have the unique properties of light specific gravity, high melting point, good ductility, large elastic modulus, corrosion resistance, fatigue resistance, high hardness and other ordinary metal materials.

As early as four years ago, Alice Group gave an order to the Special Metal Materials Research Center of Alice Comprehensive Applied Science and Technology Research Institute and the special aluminum profile production and research company that had just been established in the second half of 94: no matter how much money is spent, you must make your own aviation-grade aluminum. \\/\

Now, this requirement was finally realized last year, when the aviation aluminum formula was researched by the Metal Materials Research Center of Alice Comprehensive Applied Science and Technology Research Institute, and produced by Alice Special Aluminum Profile Production and R&D Company. After the acceptance of the relevant departments of the national aviation materials, the performance indicators completely exceed the existing standards of China's aviation-grade aluminum, but the cost is lower, with this, Alice Group has successfully become one of the suppliers of aircraft aviation aluminum in China, Alice Metal Materials Research Center also has an equal position with the major domestic metal materials research institutes.

"Our research center has spent a lot of money to develop super strong aluminum alloy profiles and their new processing technology, which has reached the domestic leading and international advanced level," speaking of his proud work, Lin Tao, the president of the metal materials research center, couldn't suppress the excitement in his heart, and danced with his hands and feet, saying that his eyebrows flew and danced, "The surface treatment of aluminum profiles in our research center uses the world's advanced nanotechnology, nano silica surface chemistry/grafting modification, and its application in high weathering powder coatings meets the requirements of aviation aluminum. We can proudly say that in China, we are the best manufacturer of aerospace aluminum! In the world, we are also among the first group of aerospace aluminum suppliers. \//\”,

To be precise, this kind of aviation aluminum should be called aluminum-zinc alloy, which is what we call superduralumin, but this aluminum alloy profile has a very prominent feature: compared with ordinary aluminum, its welding performance is extremely poor! So we can see in almost all airplanes with aluminum fuselage skin, the aluminum of the fuselage skin is all nailed together with rivets, not welded together. This is true whether it is an advanced American fighter jet or an ordinary civil airliner.

But if an aircraft wants to take off and land and stop normally, in addition to the fuselage to maintain sufficient strength, the weight should be as light as possible, there is also a very important point, that is, the strength of the landing gear material must be very strong, very strong, because only the landing gear with high enough strength can support the huge impact force of the aircraft when landing.

Although a variety of composite materials are used in the design of today's aircraft, in the landing gear, since the first aircraft in history, the landing gear materials used are all high-strength alloy steel! Some people may think that the high-quenched nickel-chromium alloy steel used in the special operations military dagger equipped in the special forces is already the alloy steel with the highest strength, but for the landing gear of the aircraft, this strength is not enough, or it cannot meet the needs of the strength of the aircraft landing gear, and it must be a higher strength alloy steel.

"The high-strength special alloy steel used in the landing gear of the aircraft, we can produce it now, right?" Zhang Lan is very concerned about this. The steel used in the landing gear of the aircraft has always been something that needs to be highly confidential, and if it can break through this, it means that the material of the entire fuselage is almost ready, although they have dug up a lot of people from the major state-owned scientific research and metal research institutes, and many people also know the formula of this material, but they still know the principle of secrecy, and they are unwilling to disclose the slightest news about this material.

For this, Zhang Lan admires these guys: to be able to research from scratch under such superior conditions as Alice Group, he would rather start research from scratch than use the previous technology and not divulge state secrets. These guys, they're all good!

"No problem," Lin Tao nodded, his face full of confidence, "This is not a difficult technique." ”

Hearing this, Zhang Lan was finally relieved: the problem of aviation-grade aluminum used in the fuselage of the aircraft has been solved, and the problem of landing gear materials has also been solved, what else needs to be worried about?

Well, there's also the issue of the plane braking when it lands. As for the problem of aircraft brake pads, this problem has long been not a problem: Alice (China) Brake System Co., Ltd. production of high-strength composite ceramic brake system has already developed a special aircraft special composite ceramic brake pad for the aircraft, the comprehensive performance is 30% higher than the original use of imported brakes, but the price is nearly a quarter lower than the imported aircraft brake pads, and now this composite ceramic brake has become the designated procurement product of military aircraft brakes.

After reading all aspects of this circle closely related to aircraft manufacturing, Zhang Lan finally had the bottom in his heart, although the aircraft engine himself could not be manufactured now, but he did not plan to build the aircraft within two or three years, right?

It is now the end of 1997, and if you can build an airplane that you are satisfied with in four years, then you can really burn incense and worship Buddha and thank God for your blessing.

Regarding the issue of writing technical information, which has been unanimously criticized by everyone for a while, Kiritsu can only say that these things are crucial to the development of the plot later. Basically, there will still be technical introductions for a period of time in the future, but with the education of the generals, I will not write like this, but try to write as briefly as possible and write more stories.

Finally, thank you for your support, bow down
