Su Feng looked at Luo Hai's shocked appearance and smiled slightly: "The ws-10A military pushes 75 thousand N and the afterburner thrust is 125 kN, which is the most cost-effective." Type B is equipped with axisymmetric vector nozzle technology, with a military thrust of 90 kN and an afterburner thrust of 150 kN, which is suitable for third-generation aircraft. The C-type we developed three years ago, with increased high-speed circulation, does not use vector technology, has a military thrust of 112 kN and an afterburner thrust of 160 kN, which is mainly suitable for fighter-bombers and strategic bombers. ”

"Awesome! That's amazing! Luo Hai heard Su Feng's statement about the WS-10 'Taihang' aviation turbofan engine, and the whole person was instantly stunned.

Shock!

It's amazing!

Luo Hai didn't expect that the domestic Shenfei Dawn Engine Company had upgraded the WS-10 'Taihang' aviation turbofan engine to such a terrifying Cheng Dù.

God, the WS-10 'Taihang' aviation turbofan engine has been improved to the C type, and each model has its own characteristics, and the performance has reached a frightening level.

The ws-10C aviation turbofan engine, the military thrust reached 112 kN, and the afterburner thrust reached 160 kN, although it does not have vector technology, but for fighter-bombers and strategic bombers, as well as heavy air supremacy fighters, its role is too great.

The J-11B and J-11A equipped with the Russian-made AL-31 aviation turbofan engine, as well as the J-16 and J-15 heavy air supremacy fighters, only need to be replaced with the WS-10C aviation turbofan engine, and their performance is increased by at least 30%.

Su Feng showed a kind smile on his face: "By the way, Xiaohai, what are you flying?" J-10A or J-11? It is not easy for a pilot who can achieve a level of secrecy up to B9. ”

"Hey, Grandpa Su, I flew the J-10B." Luo Hai smiled at Su Feng.

Su Feng heard the model Luo Hai said, and nodded with satisfaction: "J-10B, not bad." At the beginning of the J-10B modeling test, it had a winning rate of more than 89% in the face of the F-16V, and more than 80% in the face of Typhoon and Rafale equipped with AESA radar, as well as MiG-29 and other fighters of the same level. ”

"So high!" Luo Hai was immediately surprised when he heard what Su Feng said.

"Hehe, the heads of the Military Commission and our big guys, we must do our best, and while ensuring the production of fighters, we must also improve the quality of fighters. However, the J-10B is generally equipped with the most cost-effective WS-10 aviation turbofan engine, and the J-10B, which was previously tested with the F-35, is equipped with a more advanced WS-10B aviation aviation turbofan engine. ”

Su Feng smiled slightly, and after eating the working meal by two, he put the lunch box aside and explained to Luo Hai.

Luo Hai nodded again and again, of course he understood this situation, the installation of the WS-10B aviation vector turbofan engine has made the performance and combat effectiveness of the J-10B canard wing fighter improve in a straight line.

"Well, by the way, Grandpa Su, when the plane enters the transonic region, is there a way to solve the air turbulence and avoid the engine from surging. And how to destroy the aerodynamic balance of the enemy plane, while ensuring that the parts of the enemy plane's fuselage and wing do not have problems, how to destroy it? ”

"Huh? Xiaohai, your question is not simple, you have focused on aerodynamics? Hearing Luo Hai's question, Su Feng's eyes suddenly lit up, and he couldn't help but glance at Su Feng in surprise.

Luo Hai smiled at Su Feng: "I studied a little fur in school, but I don't know much about it. ”

"Since we are in love, I can also sue you. For transonic flow, there is a simplified equation for transonic flow, both around and inside. According to the different characteristics of the transonic flow field in the subsonic region and the supersonic region, the mixed difference method with different difference formats is adopted, which has a promoting effect on solving the transonic flow. ”

Su Feng nodded and said to Luo Hai with a smile.

"At the same time, a better finite element method can be used to calculate the number jù and solve the situation of air turbulence. Of course, there are many other methods, such as transonic supercritical wings, where shock waves still do not occur on the supercritical wing surface after the flow Mach number exceeds the critical Mach number. Of course, you probably know all of this, but it's the most practical and effective way to do it right now. ”

"I see." After Su Feng's explanation, Luo Hai nodded thoughtfully.

"As for what you said, it is difficult and simple to destroy the aerodynamic balance of the enemy aircraft and cause it to stall or tail spin while ensuring that the parts of the enemy plane's fuselage and wings are intact. It was too difficult for the pilot to operate. In terms of disrupting the aerodynamic balance alone, it is only necessary to disturb the airflow of different pneumatic control surfaces many times, and hide in the area with high air turbulence above 4,000 meters during the battle. ”

Then, Su Feng explained to Luo Hai and answered his second question.

When Luo Hai heard this, his eyes lit up, and he immediately wrote down Su Feng's words in his heart, and then asked, "What if it's at a low altitude, Grandpa Su?" ”

"Low-altitude, it's simple. Due to the high density of gases at low altitudes, if the environment is not good, such as heavy rain, sandstorms, and the density of inhalable particles in the air, it is only necessary to disturb the air intake of the enemy aircraft, or it is pneumatically controlled, and there is a high probability that the aerodynamic balance will be destroyed. Su Feng smiled slightly, and took the trouble to answer Luo Hai's questions:

"However, you need to understand the number and performance of fighters in various countries, and there has been no good way to deal with tail spin between American-made fighters and British-made fighters."

"Hmm." Luo Hai nodded and wrote down what Su Feng said, just like a student, constantly absorbing knowledge.

Looking at Luo Hai, who nodded again and again, Su Feng's eyes flickered, and he couldn't help asking: "Xiaohai, I don't think you are an ordinary pilot, what you said about destroying the aerodynamic balance of the enemy plane, this can only be done under very extreme circumstances." For example, the J-10B that flew against the fighter just now used the trick of destroying the aerodynamic balance of the enemy aircraft. However, this is very extreme, and it must be said that he is gambling with his own life. ”

"Grandpa Su, actually, I am the pilot of the J-10B just now." Luo Hai smiled slightly and said respectfully towards Su Feng.

When Su Feng heard Luo Hai's words, his eyes immediately widened, and he looked at Luo Hai incredulously: "You! How is this possible! ”

Incredible!

It's incredible!

Su Feng didn't expect that the pilot who had good literacy and chatted with him until now turned out to be the pilot who flew the J-10B just now.

"Hehe, aren't you surprised." Luo Hai looked at Su Feng's incredible expression, with a smug smile on his face, and smiled.

"Smack!" Su Feng suddenly slapped Luo Hai on the back of the head, which immediately made Luo Hai, who was smiling proudly, come to an abrupt end.

Su Feng looked at Luo Hai, who was depressed, and suddenly showed a smug smile on his face, and then said: "Surprised, you kid dare to be proud in front of me." Good fellow, you kid is hiding a lot of ground, and you've deceived me. Say, which troops. ”
