Chapter 1144: Turbofan-15 project

When Qin Guan said so, everyone was solemn.
Because, not long ago, the Eagles started the tender for the next generation of fighter jets.
For the Eagle State, it has always been ahead of the entire era. While Xiong State was still struggling with the technical problems of the third-generation Su-27, the Eagle State had already looked forward to the future and began its next-generation fighter project plan.
Of course, people also know that it is not for use now, but for the next-generation "Advanced Tactical Fighter (ATF program used in the mid to late 1990s.
The current F-15 is already against the sky, and its performance has to exceed the F-15 in an all-round way. Of course, there are some hard indicators.
In addition to requiring good maneuverability, ATF must also highlight good agility, high stealth, supersonic cruise and short take-off and landing capabilities. Correspondingly, the engine used for ATF requires a thrust-to-weight ratio of 10.0, a high intermediate thrust, and vector nozzles.
This plan is too advanced, and the average company can’t figure it out. Therefore, it can only be a combination of various companies. For example, the YF-22 plan jointly proposed by Lockheed, Boeing and General Dynamics, Northrop, Mai The YF-23 program jointly proposed by the two companies participated in the bidding competition.
At the same time, in terms of engines, Yingguo Pratt & Whitney and GE are the main ones, respectively proposing PW5000 (XF119) and GE37 (XF120) engines with a thrust-to-weight ratio of 10.0 and 133.6kN to compete.
In this way, the development of Yingguoren's fourth-generation aircraft has gradually begun.
For China, fighter jets are still working on the third-generation aircraft. Even so, they are much better than in history. After all, in the history of the parallel world, the current Han is still repairing on the J-7. Eight, these are still key projects and are kept secret.
Everyone has just begun to gnaw on the hard bones of the third-generation machine, and at the same time, the fourth-generation machine cannot relax. After all, this is an opportunity to catch up. For example, Mr. Song has already begun planning to develop a fourth-generation aircraft with a duck layout. After all, the 6611 has the most abundant technical reserves in the duck layout.
After Lu Lao copied the Tomcat fighter for surveying and mapping, he will definitely improve on this fighter, with stealth performance and the advantage of variable swept wings.
"If we are to fight against this project of the Eagle Country, then our engine must not only achieve a thrust-to-weight ratio of 10, but also have a large intermediate thrust, so that the fighter can fly at supersonic speed without afterburner. The vector nozzle, in short, is not as difficult as usual."
Elder Kang knew the difficulty, and at this time, every one of these things he mentioned had technical difficulties.
"Yes, we have a great difficulty, but if we are afraid of the difficulties, then we will always be behind, and we will always be behind the of others. Only by facing the difficulties can we develop." Qin Guan said: "Are we going to be laggards forever? If we are behind, we will be beaten. Isn't it the first time we accept this lesson?"
If you fall behind, you will be beaten. Of course, everyone knows that the history of modern Han is a history of blood and tears.
Qin Guan said that, everyone's hearts were stirred: "Yes, we must not be afraid of difficulties, we must aim at the highest peak of this era."
"Our North Industries Corporation will also find ways to obtain some materials from abroad to improve our level. Our materials must also be developed as soon as possible. In short, we think in one place and work hard. We must Climb the Mount Everest of this aviation industry."
"Yes, that is, no matter how difficult it is, let's him!" Old Wu clenched his fists, as if he was also participating.
Mr. Wu is already old, and this new engine project is not his turn. He only hopes that he can see this engine appear after retirement, so he is satisfied.
Qin Guan can find technical information, but if you have technical information, it doesn't mean that you can imitate it. It just came out from 4430, isn't there a failure experience?
Qin Guan is mentally prepared, this will definitely not go smoothly, but his own pre-research will never give up.
"You pre-research first, and the results of your pre-research can also be used to improve our engines." Old Wu continued.
In later generations, the country of Xiong disintegrated, and their planned AL41 engine was completely dust-sealed. This same project with a thrust-to-weight ratio of 10 was impossible. However, the pre-research results on this project were all used for three. Uncle, the improved third uncle's thrust has approached 14 tons.
In this way, huge research and development funds will not be wasted.
Old Kang smiled: "You will pick up the ready-made cheap."
"It's all for the aviation industry of the motherland." Old Wu said: "Good things, don't even think about hiding them."
Qin Guan came to the Gas Turbine Research Institute and gave them an arduous task, and this project is equivalent to the turbofan-15 for later generations.
This kind of engine with a thrust of more than 150 tons and a thrust-to-weight ratio of about 10 was jointly developed by a number of factories, and its core engine is also from Xiong Country.
That’s when the bear country was disintegrated. Because of their poor economic conditions, many fighter projects were forced to suspend, including the latest vertical take-off and landing fighter Yak-141. After this aircraft was terminated, the supporting R The -79 engine was no longer used, and no other fighters used this engine, so this engine was introduced.
The full set of design drawings and technical data of the R-79 engine, especially the introduction of production equipment and production process data for manufacturing the core engine of the R-79 engine, is equivalent to bringing this engine over.
As for the supporting vector nozzle technology, it was subsequently introduced, including the R179-300 engine design scheme with a thrust of 20 tons and the R-79M design drawings and technical data.
Under this circumstance, the surveying and mapping imitation of this R-79 engine has just begun, and the surveying and mapping imitation work of the three core components of the R-79 engine's high-pressure compressor, combustion chamber, and turbine started first.
In the surveying and mapping imitation of the three core components, it boldly advocated the adoption of many cutting-edge design technology achievements of aerodynamics and the application of a large number of new materials and new processes, thus breaking through more than 120 key technologies.
At that time, it was the 6624 Institute. After obtaining the R-79-300 engine design scheme with a thrust of 20 tons and the R-79M design drawings and technical data, they developed the YWH-30-27 core engine, YWH-30 The --27 core engine is based on the R-79 engine core engine for in-depth development.
CJ-2000 is further developed based on the YWH-30-27 core machine, and WS-15 is the code name of the CJ-2000 model.
This is the source of power for the J-20 engine. Of course, in 2020 when Qin Guan crosses, this engine is still under development.
But now, Qin Guan has no plans to develop this turbofan-15. Of course, he has to do it on the basis of the mature F119. This will be a real self-developed model, because there is no such equipment in the weapon cemetery. It can be found through the weapon data cemetery.
