It took three days to test the turbofan 10A engine intermittently, and finally came up with the thrust loss data of the turbofan 10A engine at different heights and speeds.

With these data, not only the turbofan 10A engine finalization review team was very satisfied, but also the 624 institutes responsible for the turbofan 10A data test were also surprised.

The Gas Turbine Research Institute is carrying out the development of the core engine of the advanced aero engine of the Republic, but the gas turbine institute, a variety of key components in the advanced aero engine, also has a variety of pre-research, for the convergence and diffusion tail nozzle that Southwest Science and Industry suddenly took out and finalized, 624 Institute also feels that the strength of Southwest Science and Industry is indeed good.

Mr. Wu, who came to watch the turbofan 10A engine test, was all kinds of surprises, and the first reaction of Mr. Wu was that the tail nozzle technology used in the turbofan 10A engine was that the core machine that had just been successfully developed.

"The convergence and diffusion tail nozzle technology on the turbofan 10A engine should be the most advanced tail nozzle technology in our and even in the world, and it will be applied to the new generation of the mid-push engine developed by the core engine in the future, which can definitely be used perfectly, and it seems that the technology of the new generation of the mid-push engine has already been prepared in Southwest Science and Industry!"

The reason why Southwest Science and Industry approved the turbofan 10A engine in the early stage was developed without a national project, not only that the turbofan 10 engine was indeed necessary to improve in this regard, but also to take this opportunity to test and reserve the convergence diffusion tail nozzle technology.

Chief Engineer Li Jufeng, who came here with him for testing, also knew about the follow-up military turbofan engine development plan of Southwest Science and Industry, and naturally knew what the new generation of medium-thrust core engine and the new generation of medium-thrust engine that Chief Engineer Wu said.

"What Chief Wu said is not bad, we have carried out the pre-research of a new generation of military mid-thrust turbofan engine early, and the current turbofan 10A engine also has the meaning of verifying new technologies. As long as the state approves the project, we can come up with a mature new generation of medium-push engines within three to four years. ”

When the Southwest Science and Industry Co., Ltd. was carrying out the intensive development of the CG-2000 engine, it used some time to conduct pre-research on various technologies promoted in the new generation of military, so as to prepare for the development of a new generation of military engines that may be possible at any time later

The words are good, and the imagination of the future is also very beautiful. But now the protagonist here is not the new generation of advanced medium push core machine that does not even have the state of the drawings, but the current military leader of the Republic Hua Dan turbofan 10A engine.

Yang Hui walked next to the leader of the review team, the leader of the review team this time is still the leader of the review team of the last turbofan 10 engine, Wu Daguan Wu Lao, the relationship between this old gentleman and Yang Hui is not bad, and the first time Yang Hui came over, he understood what Yang Hui was going to say.

Nodding with great satisfaction: "Don't worry, the performance of this turbofan 10A engine has indeed reached the specified indicators, and the convergent diffusion tail nozzle developed is also the first great breakthrough in China, and the review team on our side will definitely not get stuck." ”

After Wu Lao's statement, the experts of the review team who came to participate in the engine finalization meeting also stood up for affirmation. The ins and outs of the Southwest Science and Industry turbofan 10 engine and the current use are also very clear.

"Rest assured, we have previously handled the development of the turbofan 10 engine, after the use of the turbofan 10 engine in the past few years, it is indeed an excellent and reliable product, the ability of Southwest Science and Industry is indeed very good, the current turbofan 10A engine will presumably inherit the excellent genes of the turbofan 10 engine, and it can also be better than the blue."

Hearing these beautiful words, Yang Hui also had a bottom on the finalization of the turbofan 10A engine in his heart, and from all aspects. This time, the turbofan 10A engine will definitely not have any more problems.

At this time, he hurriedly responded: "The review team means that there is no problem with the finalization of our engine, and I don't know when we can issue an official document." We are also preparing to produce a batch of engines in small batches for use in the FC-17 project, which is also waiting for the engine. ”

Since Yang Hui asked all the words here, Wu Lao, as the leader of the review team, naturally gave a quasi-letter, anyway, all the procedures for the finalization of the engine have been completed, but it is just a matter of a document.

I looked at Yang Hui who was still digging into the bottom of the problem helplessly, for Yang Hui's style. Wu Lao is also a little helpless, Yang Hui still hasn't changed it after so many years, but there is no need to change this good habit.

"Okay, our review team will issue you the engine finalization document tomorrow, and you can just wait here for two days." Anyway, the finalization of the core machine here is also related to your Southwest Science and Industry, and it is not bad for you to take a look here. ”

Yang Hui agrees with Wu Lao's statement, but the engine is very cumbersome, and the core machine is also not simple, which is related to whether the development of the engine will be smooth in the future, and the review of the core machine is even stricter. The previous review of these design data, without ten days and half a month, it is absolutely impossible to enter the actual performance test of the core machine, and it will take about a month to finally come out with the results.

It is absolutely impossible for Yang Hui to spend nearly a month in 624 to read these materials, and there is another very important thing to come to Fucheng this time. Regarding the radar issue of the FC-17 Lightning Joint Strike Fighter project, it is now necessary to see the progress of the Changhong Factory, and Yang Hui still needs to see the actual development progress.

After getting the turbofan 10A engine finalization document issued by the review team, the personnel who came to participate in the turbofan 10A engine finalization with other people from Southwest Science and Industry took the car to leave the 624 Institute and enter Fucheng again.

Here, the team separated again, Yang Hui and three other radar system technicians of the FC-17 project went to the Changhong factory together, and the other team members naturally returned to the southwest science and industry, and they needed to prepare to organize the production of the first batch of turbofan 10A.

At this time, although Fucheng developed very fast, due to the special military background of Fucheng, it still had a great tilt towards military units in many cases, and Changhong Factory was one of the beneficiaries. Yang Hui almost didn't make much effort to come to Changhong Factory again, and Yang Hui was naturally greeted by Director Ni, who is now leading Changhong Factory by leaps and bounds.

After seeing Yang Hui, the factory director didn't say too many polite words, he knew Yang Hui's style of acting, so he took Yang Hui directly to a place that Yang Hui didn't expect.

"Take a look, this is our electronic components manufacturing plant, after the development of the past few years, relying on our supporting J-74, J-75 series of fighters supporting radar order projects, as well as our Changhong factory electrical manufacturing orders, and some other unit orders, this factory now has reached the 7,000 yuan mark, compared to our Changhong factory civilian projects are not weak!"

Hearing this, Yang Hui didn't understand what was going on at first, and after thinking about it for a long time, he suddenly found out what was going on with the factory here, and this factory can also be regarded as a fixed asset of Southwest Science and Industry.

This was when the Blue Fox Radar was introduced, because the Changhong Factory had no foreign exchange for the introduction of radar, and in the end it was introduced at the expense of Southwest Science and Industry, and the return was that Southwest Science and Industry got half of the shares of the factory, but only participated in the share or future share sale.

And the reason why Yang Hui doesn't remember this factory very much, or because the frequency of this factory in the financial statements of Southwest Science and Industry in recent years is too low, this factory is indeed profitable, and the expansion rate is also quite fast, and the annual profit is used for the expansion of the factory, which is similar in nature to the civil small piston engine factory of Southwest Science and Industry, and the two factories have not provided cash flow to Southwest Science and Industry.

In addition, the contract at that time stipulated that Southwest Science and Industry only held shares in the factory, only the right to supervise and not the right to manage, until now Yang Hui remembered that Southwest Science and Industry still had shares in such a factory, which was a golden chicken that laid eggs in the future.
