For this credit, Tan Zhenhua didn't intend to be modest at all.
As mentioned in the previous article, an aero engine needs to burn a lot of money and time from the initial design to the final maturity and use (see Chapter 829 of the fourth volume of this book, "The Three Generations of Aviation Development"). The experience of the undisputed first country in the development industry, the Americans, starting from the development of the core machine, going through the entire development process of SIA, usually requires hundreds of thousands of hours of test time.
These hundreds of thousands of hours are of course distributed in all links of engine development, of which the longest time-consuming is actually the first and last two links, that is, the development of the core machine and the various working conditions of the final machine. Testing session.
For the current "Huashan" engine, a shortcut was taken, because it uses a ready-made, well-tested core engine-Spey MK555. In the contract between Tan Zhenhua and Rolls-Royce, this All the technical information of this engine needs to be disclosed to China, including all the test data when the core engine was originally developed. This greatly saves China’s needs for further research and development of this engine. Work and experiment.
The core engine is undoubtedly the most critical and important core component of the entire aviation engine. For the development of the entire engine, the time and other resources spent on the core engine are correspondingly the highest.
The development process of the core engine was omitted, and the development time of the "Huashan" engine was greatly shortened. However, even so, in order to add an afterburner to this mature engine, Liu Daxiang and his team have already It took more than ten thousand hours of test time.
Such a long test time should be placed in the same working state as before. It will not be completed in ten years. After all, it takes time not only for the test, but also for finding problems, adjusting and improving designs, and producing new parts. Yes, this is also the reason why it takes a long time to develop a new aviation hair, sometimes even whitening the hair of a generation.
For example, as mentioned in the previous article, Liu Daxiang is currently undertaking the national project, which is the famous "high push pre-research" project. This project began pre-research in 1980 and was officially approved by the state in 1994. The "Advanced China Propulsion Core Aircraft" completed the national phased acceptance and reached a stable state in 1997. The country approved the next step of the China Propulsion Demonstrator's complete machine development task until it was finally dismantled in 1999. This has not yet completed an aviation development 20 years have passed since the entire development process of the company. If we really go through the entire process, it will take 30 years or more for this Zhongtuihang development to reach a mature and usable state.
Some students are about to ask, it takes 30 years to develop an aviation development? Are you kidding me? Are all the advanced voyages of the Americans popping out of the cracks in the rocks?
Um, this, I have to admit that the Americans have a solid foundation in this area.
The aero engine is the jewel in the crown of modern industry. It covers many fields such as basic materials science, thermodynamics, dynamics, precision machining, hydraulics, automatic control, petrochemicals, etc. To develop such a device requires the entire Supported by the country’s scientific research and industrial system, the United States, which has accumulated deep in these aspects, has unique advantages, and it can also obtain the resources of the advanced industrial system of the entire Western countries for its own use, such as purchasing Hans’s most advanced machine tools, The best precision bearings, the highest grade carbon fiber in Japan, the purchase of the latest British aviation development basic research patents, and so on.
On these foundations, in order to win the Cold War victory over Soviet Russia, the Americans were willing to spend a lot of money to burn money in various cutting-edge fields, piled up huge databases with massive tests, and in countless trial and error. Finally a way out.
Let's put it this way, the American people piled up countless dollars on this road.
But even so, in the field of aviation development, Americans have pitted many times. For example, when the F15 was mass-produced, the Pratt & Whitney F100-100 engine equipped on it had encountered major problems since 1974. By 1979, 1,100 engines of this type had set a record of 660 stalls caused by surging in 250,000 flight hours, often stalling as soon as the afterburner was applied, resulting in the F15 fighter aircraft equipped with this type of engine being awarded the " The famous name of "Hangar Queen".
In the field of aviation development, there is no shortcut to "overtaking on a curve". The only feasible way is to burn it honestly, "stack" the data with massive test experiments, and finally "stack" the best result.
I am afraid that the only feasible way to save time is the method Tan Zhenhua now uses, which is the same as the Americans and even worse than that-burning money, burning money to buy time!
Isn't it just a pile of data? Let's change our thinking and upgrade from "single-core" computing to "multi-core" parallel. As long as the "bus" is wide enough, all the data throughput will be piled up for you!
When did China play "Crowd Tactics"? This time it was just a little bit of a facelift, replaced by "machine sea" tactics!
Back then, China was engaged in the "910 Project", that is, the unsuccessful "Turbofan 6". From 1964 to 1983, it was dismantled. In nearly 20 years, a total of 10 test prototypes were manufactured. But this time?
According to the hard cost of more than 3 million prototypes, Tan Zhenhua gave 70 units in one go. For this alone, he invested more than 200 million yuan!
In addition to the investment in material development, test consumption, equipment transformation, personnel salary bonuses, and various technical research and development of supporting enterprises, it is clearly recorded in Tan Zhenhua’s own small account book that for the "Huashan" today, In 4 years, he has spent more than 800 million yuan, which is 800 million in the 1980s!
This money is N orders of magnitude more than the amount spent by Liu Daxiang's state-invested "pre-research" project from 1980 to the present!
You know, in the last time and space, the "Flying Leopard" created by China after 20 years only cost 1 billion yuan.
With such a generous investment, Liu Daxiang, who presided over this project, felt a little embarrassed. Although he had seriously warned Tan Zhenhua to engage in aviation development, this is a pit of "burning money without blinking", but He really didn't expect that this rich master Tan really planned to fill this pit with banknotes. He would spend hundreds of millions of banknotes without even blinking his eyelids!
You know, there is also a "TF41", which is "Qinling II", and a "MK606" localization project that is being advanced in parallel during the same period!
How could this kid be so rich? He robbed the national treasury of which country, right?
This is the thought that occasionally pops up in Liu Daxiang's mind in the dead of night, but when this kind of thought emerges, he will laugh at himself and think it is too unreliable and forget it.
What he didn't know was that he was right. Tan Er did rob another country's treasury, and more than once, there was one of them now in progress...
