However, turning their heads, the old experts and technicians in the institute are also full of hope for China's aviation industry, because the turbofan 10 has a more advanced design after all, and the turbofan 6 has little room for improvement due to the backward design, and they can also understand the decision of the superiors.

Several units of the exchange showed great curiosity about the joint venture aircraft factory of China Eastern Airlines, and they saw that most of the technical staff of China Eastern Airlines operated simple small computers, like a large suitcase that could be carried around with the screen closed.

In particular, people in China Eastern Airlines can generally use the text tools and drawing tools on the computer to operate, which also surprises the exchange unit. How did they think that the popularity of computers in Dongxing Group is quite high, and these employees have been trained in computers after they have joined the company, and the luxury of one person ensures efficiency!

They copied most of the technical data from several research institutes, and some of them even entered them into small floppy disks. The scanners and copiers they were carrying were products of Philips and Toshiba, which also represent the highest level of the office today, and these machines are very clear and color saturated, and they are much more advanced than the machines in the office.

Seeing a large set of technical data being brushed away, the scientific researchers of the exchange unit were distressed and secretly smacked their tongues, how much foreign exchange is needed for these equipment used by this company to buy, and seeing that their inks are also imported, China Eastern Airlines Industry is really rich!

In fact, they are too worried, and there are already companies dealing in second-hand office equipment in China. Moreover, Dongxing Group is also a first-class company in the industry in this regard, and even Dongxing has gradually contracted a large share of office equipment and second-hand toner cartridge transactions in Europe, the United States and Japan.

The toner cartridge not only determines the quality of the print, but also determines the amount of money that the user needs to spend in the process of using it. In laser printers, more than 70% of the imaging components are concentrated in the toner cartridge.

Yang Wanli not only took the people of China Eastern Airlines Industry to copy all the design ideas and technical data of the turbofan 5, 6, 6G and 10 of the 606 Institute, but also did not let go of the details of the material, process and manufacturing, and personally took the technical personnel to the workshop to directly understand the manufacturing difficulties and process know-how of blades, turbine discs and other components from the front-line workers.

The people of China Eastern Aviation Industry learned key technologies such as powder metallurgy manufacturing process, compressor adjustable blade technology and blade regulator from Liming Engine Factory. The domestic aero engine compressor technology is very backward, but in the 70s, it also formed a certain level of technology, which is more than enough than the above. Design ideas and experience can still be learned.

Among the top compressors in the world, the compressor in the United States has the highest boost ratio, and the actual boost ratio is not a theoretical value.

In order to pressurize as much air as possible, the compressor must not leak, and the blades are very close to the compressor casing, so close to the distance that they are almost touched, so the air compression efficiency is very high. But the blades were so close to the receiver that the engine vibrated at 20,000 revolutions per minute. It is necessary to ensure that the blades do not touch the compressor casing, which is a very high level of manufacturing. China does not have such superb processing technology, and the compressor blades must be far away from the compressor box, so that the compressor will leak, so the pressurization ratio is low. This is not only about the design and manufacture of the compressor, but also about the accuracy of all engine segments!

The Precision Instrument Research Institute of the Eastern Star Group is working towards a processing size of less than one micron, and now this department has been split into a Los Angeles company in the United States and a domestic company, and the two are completely independent without any relationship. The project initiator and R&D personnel are different. This is also in order to maintain the research and development speed of Dongxing Group in the field of precision instruments, foreign competition is very fierce, precision instruments are related to Lin Johnson, a number of industries would rather be split into two companies that have nothing to do with each other, he does not allow the slightest delay!

If the relationship is forced, the domestic agency is also a supplier of parts and components. Lin Qiangsheng believes that the turbofan 6 level of the compressor Dongxing can be manufactured, in the field of compressors Dongxing started very early, but the design and technical ideas can not be manufactured, this is the importance of 601, 606 and other aviation industry research institutes, without their help it is really unrealistic to start on a blank piece of paper!

Of course. China Eastern Aviation Industry Company is not letting these units pay in vain, they are old-timers in the aviation industry after all. When I understand that it's time to resent the Eastern Aviation Industry, how can I continue to communicate!

The state can arbitrarily transfer the personnel and technology of these enterprises, but Lin Qiangsheng does not have such a thick skin and qualifications to do this kind of thing. Yang Wanli also submitted a list of equipment purchases to these research institutes and aircraft factories, powder metallurgy vacuum furnaces, turbine disc extrusion molding equipment, titanium alloy aluminum alloy casting equipment, etc. are all relatively important research equipment and manufacturing equipment, and the price is not low enough for these units to make a lot of money.

Lin Qiangsheng and Yang Wanli have already studied the development roadmap of China Eastern Airlines, that is, they plan to learn from other people's works first. Start from the model with low material and process requirements and simple structure, whether it is an aircraft or an engine; And strive to do processing for other aviation enterprises, strive to contract parts manufacturing, gradually improve their aviation manufacturing capabilities, and develop into a multinational aviation manufacturing enterprise that can produce and manufacture multiple systems and accept foreign entrusted tasks!

At present, they hope to be able to undertake the processing task of Hafei Zhijiu parts, as well as the processing commission of Yun-12 transport aircraft parts, and so on, and when the technology accumulates to a certain height, China Eastern Airlines will also strive for orders from foreign aviation manufacturers.

China Eastern Aviation Industry should first absorb the existing foundation and nutrients of these excellent domestic aviation enterprises. This kind of development has undoubtedly added a good starting point to China Eastern Airlines. And it is only in China that this can be done, and Lin Qiangsheng is grateful to these exchange units!

Yang Wanli led the China Eastern Airlines delegation to visit the 601 Flight Design Institute, the 606 Flight Power Design Institute and the Liming Engine Factory, and successively inspected many things that were helpful to the construction of China Eastern Airlines. These old-timers did not hesitate to provide them selflessly, after all, there has always been this kind of sharing tradition in China, and in the future, this joint venture will have the technology itself.

The goal of China Eastern Airlines is to figure out how each part of the aircraft works, how it works, how it works, and fully imitates it. By trying to modify their design, find the rules, summarize a set of theories by themselves, cultivate and introduce talents, and constantly absorb advanced technology and technology at home and abroad. At the same time, it is also the last to manufacture components within our capacity according to our own material and process level and make full use of the opportunity of international division of labor and cooperation, increase one by one, and manufacture a series of products with advanced reliability and advanced performance suitable for our own development!

Of course, Lin Qiangsheng is not the only one with these ideas, he also wants to get some technical support from abroad, so he has to use some brains in this regard!

Yang Wanli and others also visited and exchanged ideas in Shenfei, which is a much larger factory than Hafei. Saying that it is large does not mean that the scale area is larger than that of Hafei, Hafei's territory is very large, and the location where it is located is the area where Unit 731 was located in the War of Resistance Against Japan.

It is said that Shen Fei's influence and technical strength in China are undoubtedly the first, and it is also the largest fighter production base in China!

Shen Fei was also quite reserved in dealing with the sudden emergence of a joint venture aircraft factory of China Eastern Aviation Industry, and the director and chief engineer personally accompanied Yang Wanli and others to the research room to visit the front line of production.

Shen Fei's J-8 II fighter has made its first successful flight in June this year, and under the condition that Sino-US relations have greatly improved, Shen Fei hopes to improve J-8 II by introducing advanced American technology, but history proves how the Americans can introduce their own fighter technology to the Chinese, and the idea of introducing American technology naturally does not come true, so Shen Fei thought that he could let the Americans help him improve the aircraft, which is always okay, hand over the aircraft to the American company and let it help the J-8 II complete a series of modernization improvements, which is later" "Peace Model" project.

Although the J-8 II is only a second-generation aircraft, it also has its design characteristics, it is mainly used for high-altitude patrols and interceptions, and its high-altitude performance is outstanding. The technical staff of China Eastern Airlines Industry just looked at the technical information of this aircraft, and did not dare to copy it casually, after all, this is a development aircraft that has not yet been put into service, and if it is taken immediately, it will be too shameful for the old-timers!

In Shen Fei and several research institutes, the people who had transferred to China Eastern Airlines also had a bumper harvest, and Yang Wanli happily walked back and forth in several rooms in the guest house, looking at the materials sorted out by the technicians and the data entered, he couldn't stop laughing.

For many years, since the fighter jets of the Kazakh military industry were dismounted in 53, Yang Wanli has dreamed of one day being able to participate in the design and manufacture of aircraft again. But seeing that the country is gradually moving the R&D center to the west and south year after year, and the personnel are all diverted, his heart has long been numb. But I didn't expect that I would be able to participate in the formation of an aircraft factory in my lifetime, and Lin Qiangsheng is also a leader with courage and strong strength, and the most important thing is that he also has an aviation dream! This made Yang Wanli's silent heart invigorate again, and the fire of dreams in his eyes was ignited again!

Guo Yubao walked to Yang Wanli's side and asked, "Master, where are we going to copy next?" ”

"Poof, haha" Many technicians laughed when they heard Guo Yubao's jokes, aren't they just copying now, and they are copying a lot!

Yang Wanli laughed and said loudly: "First north and then south, the next step is to go all the way west to Xi'an!" (To be continued.) )
