After Premier Zhu finished his speech, he also shook hands with the senior staff and technical backbones of Yonghan Company, and Wang Yonglin also introduced them one by one.

These people were very excited to shake hands with Premier Zhu, and many of them did not expect that even the prime minister would come to the company for inspection this time, which shows the importance that China attaches to the company.

The CCTV news reporter who followed also filmed the situation of the prime minister shaking hands with the employees of Yonghan Company at this time.

In the afternoon, Zhu Ronghua was also talking to Yang Jie in the conference room.

"The last time I looked at the two bombs and one star credit Academician Wang Hengyu, he also put forward the proposal that Huaxia must engage in a large aircraft project, and I also asked some other academicians for their opinions, and they also discussed that the development of a large aircraft project is of great strategic significance to the country, and I also want to hear your thoughts. ”

Zhu Ronghua looked at Yang Jie and asked.

"Prime Minister, I also feel that we should embark on the development project of a large aircraft as soon as possible, and the question is what kind of large aircraft we want to make and what kind of method we want to use to make a large aircraft. ”

"Tell me what you think. Zhu Ronghua asked with interest.

"Prime Minister, our company has made a guess, according to the current economic growth rate of Huaxia and the expansion of the scale of the domestic market, it is expected that ten years later the country needs about 2,000 single-aisle narrow-body passenger aircraft, if our domestic passenger performance accounts for one-third of the share, then the total output can be close to 700, with each passenger aircraft equipped with 2 engines, plus spare engines, the production scale of supporting engines has also reached as many as 2,000 units, according to the current production of the same type of large bypass ratio turbofan engine produced by these foreign aviation giant companies each tens of millions of US dollars, this is more than 200 billion US dollars of market size, plus the aircraft platformThis is a market size of five or six hundred billion US dollars, which is enough to support the project of domestic large aircraft. ”

"Now Huaxia has established a high-altitude platform with independent intellectual property rights, and controlled the high-altitude platform technology below ten tons of thrust, on this basis, it is not particularly difficult to build a large bypass ratio turbofan engine that can experiment with 20 tons of thrust. ”

"Although China has initially controlled the construction of high-altitude platforms, it is comparable in number to Europe, the United States, and the United States. The Russian high-altitude platform is still very grand, the United States has nearly 10 experimental bases, with 10 high-altitude platforms, dozens of high-altitude experimental cabins, Britain and France and Russia are more than us, a new type of engine development, need to occupy 3 to 4 high-altitude cabins, 2000 to 4000 hours or even more high-altitude imitation experiments, the engine high-altitude platform performance test for a month's workload, equivalent to 300 take-offs and landings of flight experiments, and the hourly use of high-altitude simulation experiments is about 1/30 to 1/6 of the degree used in flight experiments, although the early investment of high-altitude platforms is very large, but once completed, can greatly reduce the degree of flight experiments。 ”

Yang Jie looked at Premier Zhu Ronghua and said: " Although the flight test bench is an important means of engine experiments, but the current flight test bench is generally a transport aircraft bomber, limited by its flight performance, can only imitate the flight altitude of 11km below, 0.85 Mach field engine experiments, while the modern engine flight altitude is 25 to 38 km, flight speed in 2.5 to 3 Mach, if it is a ground test if it creates a problem, you can quickly rest, if it is a problem in the aircraft experiment, then the trouble is big, the application of high-altitude platform does not have this danger. ”

"At the same time, the high-altitude platform can imitate a variety of harsh environmental conditions, some of which are impossible to emerge in actual flight, which is conducive to ensuring the reliability of the engine. In addition, if the application of the flight platform needs to be tested in the field, the development staff must travel thousands of miles to find a place, which is time-consuming and costly, while with the high-altitude platform, manpower, material resources, financial resources and time are greatly saved. ”

"According to the experience of some of our company's employees who have participated in the development of several engines, in order to successfully develop a high-performance afterburner, it is generally necessary to conduct 2,000 hours of full-scale afterburner experiments on a high-altitude platform, so as to ensure the reliability and safety of the developed engine. ”

Speaking of this, Yang Jie smiled: "In addition, with high-altitude platforms, non-traditional aero engine experiments can also be carried out, and now with the development of hypersonic technology, some new concept engines can also be tested with high-altitude platforms." ”

Zhu Ronghua also nodded approvingly when he heard this.

Yang Jie said with a smile: "If we can build a high-altitude platform with a suitable thrust of 20 tons within a few years, the turbofan engine launched and the PD-90 aircraft developed and produced by Pratt & Whitney Company will be established, and with the help of the platform of the MD90 produced by the Chinese aviation company and the original McDonnell Douglas Company in the United States, the process standards for production, processing and assembly have been established with reference to the process standards of the original McDonnell Douglas Company, and there is a lack of standard systems in other aspects." ”

"Not to mention anything else, the domestic standards are different in the development of aero engines, I think these domestic aviation companies are really much worse than the standards established by your company!"

Zhu Ronghua looked at Yang Jie and said: "Your standards in aviation development are on par with Rolls-Royce Company, and I think the domestic standard system for engines is in accordance with your company!"

"Huh?" Yang Jie was stunned: "Our company's engine has not been tested for a long time and the high-altitude platform has not yet been completed, if the country comes according to our standards, it is not convincing." ”

"Some of your company are technical experts who have experience in the development of several engines, which is much stronger than the other four domestic aviation development companies, and it is based on your standards!" Zhu Ronghua said decisively.
