Chapter 774: Positive circulation

Yes, it's nice to have money.
Tan Zhenhua knows that in the history of his previous life, if there is money, China is likely to have a mid-thrust engine with measurable performance as early as the 90s.
Liu Da thinks of the Gas Turbine Institute, Tan Zhenhua is not an unfamiliar name, he is by no means just as Song Wenhua introduced, he is a well-known aero engine expert in China.
If Wu Daguan is well-deserved as the "Father of China Aviation Engine" for laying the foundation of China Aviation Engine, then Liu Da thinks that among the second generation of aviation engineers, he is definitely the most capable. The strongest and most influential one is the current first person in China Aviation Development.
It was this man who was born in 1937, graduated from the Beijing University of Aeronautics and Astronautics, and was trained by Xin Huaxia himself, which laid the foundation for the research of Huaxia turbofan engines.
He himself served as the chief engineer, first chief designer or one of the main technical leaders of several large-scale national defense science and technology pre-research projects and national key projects. Under his leadership, 3624, the China Gas Turbine Institute, were constructed It has become China’s largest aero-engine test and research base and pre-research center, and he himself presided over the construction of a large continuous high-altitude simulation test bed necessary for independent research and development of aero-engines.
He is also the reviewer of the National Design Specification for Turbofan Engines.
These achievements made him the well-deserved first academician of the Chinese Academy of Engineering.
However, among the countless scientific research achievements of Academician Liu in his life, there is one that is full of honor and regret.
This scientific research result is the "pre-research plan for high-performance propulsion system engineering," historically called "pre-research on high-performance propulsion.
This project started in 1980. It is said that the rabbit family obtained a classic F404 engine of General Electric Company of the United States through a certain channel, and its performance was immediately shocked by a crowd of onlookers after a test run. People, at the same time, also discovered that the Rabbit family has to go a long, long way to get the same performance engine...cough cough cough cough.
(Qian Zhiyu solemnly declares that the content of the previous paragraph is purely Internet gossip from a suspicious source without any stone hammer.)
The core goal established by the "high-power pre-research" program is to analyze and pre-research the F404 engine, develop a mid-power core engine equivalent to the F404 core engine, and provide technical reserves for China's self-developed turbofan engine. The project takes China Gas Turbine Research Institute as the chief engineer unit, and more than 1,000 senior and intermediate scientific and technical personnel from 24 factories, institutes and universities across the country participated. The leader is Liu Daxiang.
This project was stumbling forward under the constraints of limited funds. Huaxia first took F404 as the pre-research object, conducted a comprehensive analysis and research on the structure, cycle parameters, cooling methods, materials and processes of F404, and then carried out research on related technologies. And breakthrough work. After 10 years of difficult research, the relevant core technology of the China Push core machine has been broken one after another, and the front technology is basically mature.
At the end of 1990, the China push core machine was officially listed as one of the 18 key pre-research projects during the "Eighth Five-Year Plan" period of the National Defense Science and Industry Commission. The 3624 Institute immediately carried out the formal development of the Zhongtui core machine, and at the same time actively carried out the demonstration work of the Zhongtui verification machine. The pre-research of Zhongtui is divided into 3 stages, namely the development of three high-performance components, the development of the core machine of Zhongtui and the development of the verification machine of Zhongtui. Among them, the three major components, namely the high-pressure compressor, combustion chamber and turbine of the aero engine, are the focus of the aero engine development.
Due to the fruitful pre-research results, the development of the China thruster core aircraft went smoothly. On December 12, 1992, the China thruster core aircraft reached the maximum speed on the ground. In January 1994, the China thruster core aircraft reached the design index. According to the China Aviation Engine model According to the naming convention, China Push’s core machine is named "Tianshan".
After more than two years of testing and adjustments, the parameters of the Zhongtui core machine have been mature and stable. In 1997, 3624 obtained the approval for the development of the Zhongtui verification machine.
At a time when everyone was rejoicing after more than ten years of hard work to finally turn the original "high push pre-research plan" into a real, engineered engine model. In 1999, the plan was terminated due to funding problems. , And at this time, the overall technical level of the central push core machine has been comparable to the F404 and the Soviet Russian RD33.
This plan was terminated because, according to China's actual needs, the development of another advanced engine with greater thrust has entered the most critical stage, and the limited funds can only guarantee one...
This is the true situation of Huaxia Military Industry at the time. It is no exaggeration to say that for Huaxia Airlines, the tragic situation at that time is like having two children in the family, but there is not much food and only enough to feed one. Therefore, it must be pinched. Die another...
It is conceivable that when this project was announced to be terminated, how many people who had been silently paying for it for 19 years shed tears.
19 years, enough for a person to go from full of green silk to frost-stained sideburns, and how many 19 years in life?
Although the results of this "high-promotion pre-research" have been affirmed at the national level, it has also played a practical role in the subsequent research and development of several domestic engines, laying the first cornerstone of China’s self-developed advanced turbofan engine. However, the failure to turn it into a real model, the "Huaxia Heart" of a war eagle soaring in the blue sky, Liu Daxiang's regret can be imagined.
However, this time is different.
Because Xiao Tan Tan is ready to blend.
This is not only because the second son of Tan is holding a lot of votes, but also because his understanding of technology with previous life experience far exceeds that of the vast majority of people in China.
Tan Zhenhua knows nothing about aeroengines, and he is also familiar with materials science. However, he knows that to promote the development of technology, it is not enough to rely on the will of the country, especially when the country is not rich enough.
He must give full play to the role of the market.
It is a shortcut to buy a ready-made Zhongpu engine solution from Rolls-Royce. Based on the Spey technology that Rolls-Royce has already transferred to China, it doesn’t cost much to derive other models, but the confidence of success is much greater. The product may not be advanced but sufficient. Practical. In addition to providing a viable upgrade plan for a large number of "J-7" internationally in the future, this new one may also include a large number of old "Phantom" series, which may also erode some of the Maozi RD33 in the future. The market, its possible market capacity may reach the level of hundreds of billions of dollars!
Only by forming this positive cycle of "investment in research and development-output of finished products-profit generation-continued investment in research and development", technology can obtain sufficient capital investment and continue to make breakthroughs.
Moreover, Xiao Tan Tan also believes that the stone of its mountain can be used for jade, holding the technology of the F404 and Spey engines, and confirming and referencing each other, will help the Gas Turbine Institute to break through its own bottleneck faster.
Working behind closed doors has never been the correct method for scientific research.
Therefore, Xiao Tan Tan is now very eagerly looking forward to the arrival of Liu Daxiang, a future academician of the Academy of Engineering.
