After confirming the export plan, the three major groups divided their forces into three groups. Norinco returned to Zhongbing with Chen Nian's technical drawings and began the trial production of individual air defense missiles and A-300 rocket launchers. Poly Technology sent people to Saudi Arabia to start Sales are warming up, and the AVIC Group represented by Lin Yongming quickly launched the J-8 transformation project.
What is gratifying is that the optimization project for the J-8 has actually been ongoing, so it is not difficult to temporarily add new design requirements.
----Of course, this is not difficult, just relatively speaking.
The current J-82 uses the WP-13 engine. This engine is completely designed for high-altitude and high-speed performance, and is adapted to the function of the J-8 as an interceptor.
But the problem is that after the era entered the 21st century, the role of interceptors has been infinitely reduced. Not only China, but even some small countries no longer need such interceptors.
Therefore, this modification will involve functional changes to the J-8, the most core of which is to replace the turbojet engine with a turbofan engine.
To achieve this, we must first build a usable turbofan engine - the WS-10 project, which is urgent.
In Institute 606, Wang Xianguo transferred three people from the project team originally responsible for the F119 engine to the WS-10 project team, bringing them the latest technology and materials.
This time, with the support of newly arrived hot isostatic pressing equipment, the WS-10 engine project has progressed much more smoothly.
For nearly two months, the members of the project team were like ants moving, bit by bit digesting Project 22, or the technology sent by Chen Nian, and then applied it to the WS-10 engine.
With the industrial machines running at full speed, almost every day, this engine that should have been formed is undergoing changes.
First, the overall blisk design replaces the previous welded and riveted structure, which greatly reduces the failure rate, reduces human tolerances during the assembly process, and greatly improves the stability of the engine.
Secondly, the materials of the combustion chamber, compressor, turbine, and fan blades were completely replaced, and the fan blades even used a perforated heat dissipation structure.
As a result, the high-temperature performance of the entire engine has been greatly improved, and the high-temperature creep problem that was originally unresolved has been solved. The theoretical maximum thrust of the entire engine has also been increased by more than 20%.
At the same time, the problem of strengthening the structural optimization originally caused by the excessively high compressor pressure ratio has also been comprehensively solved. The new single crystal material directly solved the problem of insufficient strength, and the weight of the entire engine was reduced by more than 15%.
Finally, the application of TBC and Alloy C coatings completes the last step of the engine's thermal working environment and completely solves the problem of high-temperature ablation at the compressor outlet.
After the entire modification, WS-10 is still WS-10, because most of the structure has not changed.
However, it is no longer WS-10.
Because this engine is no longer the original WS-10 that was pieced together, had extremely poor technical maturity, and had an impressive failure rate and longevity.
It's been given a new lease of life!
After ground testing, this engine was finally determined to have a rated thrust of 13.9 tons, a peak thrust of 15.2 tons, a thrust-to-weight ratio of 7.8, and a total weight of only 1,600 kilograms, which is 100 kilograms lighter than the AL-31FN.
Moreover, whether it is high-altitude, high-speed performance or low-speed performance, this engine is not weaker than the AL-31FN, not to mention its stability.
However, looking at the excellent data, many researchers participating in the WS-10 project invariably raised a question:
This engine...is really going to be sold?
…
No. 601, in the temporary office of the general manager.
Wang Xianguo and Lei Gang sat opposite Lin Yongming, carefully looking at the frowning man in front of them, and no one dared to disturb him.
After a long time, Lin Yongming put down the information in his hand and said:
"Is this the engine you built? Is this your J-83?"
"Has the data been verified? Are you sure it's not a false bid for foreign trade?"
"Why is it so high...these data are much higher than we expected. If this happens, I won't be able to sell takeaways!"
Lei Gang and Wang Xianguo looked at each other, with a tacit smile on their faces.
If Lin Yongming's tone is like this, then they can rest assured.
So, Wang Xianguo spoke before Lei Gang:
"Leader, the current data is indeed a bit over the standard, and the cost is also high, but I promise that it will not delay export foreign trade."
"My thinking is this, no matter what the situation, it is always good to have technological breakthroughs."
"So, in the WS-10 improvement project, I did not limit the performance of the project team. Any new technologies or breakthroughs were used directly without considering the manufacturing cost."
"But if we want to export, it is very easy to make a foreign trade version. We just need to reduce the materials and simplify the process..."
After hearing Wang Xianguo's words, Lin Yongming shook his head helplessly.
"You call it a little over the standard? Is the thing you are working on now still the same thing as the WS-10 we originally designed?"
"According to your approach, the cost of a single machine will be in the tens of millions, and exporting will definitely not be a concern."
"what is it now?"
Wang Xianguo smiled and asked knowingly.
"What else can we do, go ahead and kill Shibai! You're just waiting for me here, right?"
Lin Yongming replied angrily. Although he pretended to be serious on his face, in his heart he was almost smiling.
Well, I just wanted you to use the scraps from Project 22 to improve an old project that was on the verge of death. As a result, you not only saved this project, but you even solved the problem of the J-10 being unable to fly to the sky. It is urgent!
Once this WS-10 comes out, what else will we need AL-31FN?
Sure enough, Chen Nian's overall vision was definitely not as simple as he thought.
At first, I thought that he was just blindly arrogant and ambitious in stopping the introduction of AL-31FN.
But after seeing him take out various technologies from Project 22 one by one, my opinion changed again.
At that time, I already recognized that he was a genius, but at the same time, he was also a slightly radical genius who was too keen on taking risks.
For a long time, I comforted myself by saying, "It doesn't matter. Being a genius means being confident. Even if you make some mistakes, it doesn't matter. As long as the organization provides more guidance and care."
But now it seems that my view of Chen Nian is still wrong!
They had no intention of making a mistake at all.
I am afraid that when he first proposed the No. 22 project, he had already predicted that technological evolution would have a reverse impact on the existing WS-10 project, and prompted this project to achieve results in a short period of time, replacing the original AL-31FN. Location.
Otherwise, how could he be so determined to stop the AL-31FN project?
How could it be possible that when Project No. 22 was in financial trouble, instead of proposing to share the budget from the readily available WS-10 project, he immediately came up with a series of products suitable for military sales after he had just issued a consultation request? Product technology?
Far-sighted.
Lin Yongming never thought that one day he would use such a word to describe a college student.
But what's wrong with this?
Having such a talented person is definitely a huge blessing.
It can even be said that it is the destiny of the country.
