Chapter 167 Is this a J-10 fighter?
The reason why the third-generation fighter design and development team came here was to see whether the Xuanwu special materials from the 077 Machinery Arsenal can be applied to the J-10 fighter.
The main reason is that the 077 Machinery Military Factory has successfully developed various types of composite materials based on Xuanwu special steel and announced the relevant parameters of various special composite materials internally.
This move immediately attracted the attention of the J-10 fighter design and development team, and then through the intermediary coordination of the Yanguo military, the two sides were able to meet.
"Chief Commander Song Wen, we will discuss the issue of special metal materials later. First, please introduce your company's J-10 fighter jet so that we can have a clearer understanding of it and better choose the special composite material that matches it. Material."
"Even if there is no suitable special metal composite material readily available, we can develop one specifically for you based on your needs."
Lin Chenran seemed very confident. After all, in the field of composite materials, 077 Machinery Arsenal is undoubtedly in the leading position.
Have this strength!
"Everyone, we need to prepare first."
Song Wen first said sorry and signaled his design and R&D team to start taking action and make preparations.
"No problem, Commander Song Wen, you prepare first. We are looking forward to seeing the J-10 fighter jet."
Lin Chenran smiled slightly.
Soon, the J-10 fighter design and development team was ready to report the situation to Song Wen.
Immediately afterwards, Song Wen began to briefly introduce the J-10 fighter jet designed and developed by himself to everyone present.
The J-10 fighter uses a high-thrust turbofan engine and a canard aerodynamic layout. It is a medium-sized, multi-functional, supersonic, all-weather air superiority fighter.
The length of the J-10 fighter jet is 14.57 meters.
Wingspan 8.78 meters
Machine height: 5.3 meters
Maximum speed: Mach 2.0
Maximum ceiling: 18,000 meters
Combat radius 1100 kilometers
Maximum range 2500 kilometers
Maximum take-off weight 19277 kg
Bomb load: 7000 kg
The thrust-to-weight ratio is greater than 1.1
Power system: The first production models of the J-10 use Soviet-made AL-31FN turbofan engines.
This made Lin Chenran a little confused. He couldn't help but ask Chief Engineer Song Wen: "Chief Engineer Song Wen, does the J-10 fighter jet use the Soviet-style AL-31FN turbofan engine?"
Lin Chenran asked: "Can the fur bears be sold to us?"
This advanced engine technology is an important strategic resource for any country and cannot be easily sold to other countries.
Lin Chenran thought further, he pointed out: "The main AL-31FN turbofan engine is the engine of the Su-27 fighter jet, which was just developed.
If we rely on foreign engine technology, we will face huge difficulties once political or economic changes occur.
Without the ability to master core technologies, Yanguo's aviation industry will always be in a passive position.
Faced with such a question, Chief Master Song Wen didn't know how to answer for a while.
At this time, a member of the J-10 fighter design and development team said: "Mr. Lin, we are just making assumptions now."
His attitude seemed unconcerned, but Lin Chenran didn't think so.
"It's unimaginable. After all, you are preparing for design and development. When the time comes, Mao Xiong won't sell the AL-31FN turbofan engine?" Lin Chenran retorted directly.
It is not advisable to rely on others for key technologies. We must have independent innovation and research and development capabilities.
"Mr. Lin, you also know that our domestic engine technology is very backward, and the established Taihang turbofan engine project has stalled."
Chief Engineer Song Wen frowned. He was worried about the current situation of domestic engine technology.
According to Song Wen's idea, if a "Yan Guoxin" can be installed on the J-10 fighter, then this fighter will be even more powerful.
However, the reality is not optimistic, because the research and development project of Taihang turbofan engine has stalled, and there is a high probability that it will not be able to catch this "hitchhiking". Song Wen shook his head helplessly, and then continued: "But we have reserved enough space and location, and we can change it to 'Yan Guoxin' at any time.
As long as the Taihang turbofan engine is successfully developed, it can replace the original engine. "
The development path of Taihang turbofan engine has been full of twists and turns.
In the previous life, the Taihang turbofan engine began pre-research in 1978, and it was not until December 28, 2005 that the design review and assessment was finally completed. The entire process lasted as long as 27 years.
Although the Yanguo military attaches great importance to the development of the J-10 fighter jet, the development path of the Taihang turbofan engine is still full of challenges.
Yanguo's domestic turbofan engine technology is relatively lagging behind, and there is a large gap between it and the world's advanced level.
Lin Chenran couldn't help but think about how to introduce advanced turbofan engines from Mao Xiong.
Lin Chenran could take advantage of Mao Xiong's downfall and introduce advanced turbofan engine technology and production lines from the opponent.
"Chief Master Song Wen, please continue!"
Lin Chenran said slowly.
The J-10 fighter jet uses 1473 pulse Doppler radar, which is a traditional mechanical scanning method.
Its performance parameters are as follows: the maximum search distance is 160 kilometers, the upward-looking shooting range is 100 kilometers, the downward-looking shooting range is 80 kilometers, and the rear-looking shooting range is 40 kilometers. It can track 16-20 targets at the same time, and can attack 6 targets at the same time. -8 most threatening air targets.
Hearing this, Lin Chenran's brows wrinkled unconsciously.
The 1473 pulse Doppler radar is just an ordinary radar, and most of the third-generation fighter jets in the world have begun to use more advanced active phased array radars.
In comparison, the J-10 fighter jet is still at the stage of using ordinary radar, which undoubtedly seems a bit outdated and backward.
This reflected the limitations of the J-10 fighter design and development team at the time. They failed to keep up with the times and chose a relatively conservative technical solution.
Song Wen noticed that Lin Chenran would frown from time to time, and he couldn't help but feel "bang" in his heart.
He attaches great importance to Lin Chenran's ideas because he is well aware of the other party's strength and talent.
Among many third-tier military factories, Lin Chenran is well-known as a genius, and his insights are often unique.
"Mr. Lin, do you have any thoughts on the use of 1473 pulse Doppler radar on our J-10 fighter jets?"
Song Wen looked at Lin Chenran and spoke modestly.
"Chief Commander Song Wen, why does the J-10 fighter jet not use the active phased array radar that is standard for third-generation fighter jets?"
Lin Chenran put forward his idea again.
"Active phased array radar?"
"Mr. Lin, what is the basic research on active phased array radar in our country?"
A J-10 fighter team member explained.
"Forehead?"
"Our J-10 fighter jets are at a very obvious disadvantage against third-generation fighter jets from other countries."
Radar is like the eyes of a fighter jet.
It has advanced radar that can detect opponents faster.
