If you want to compare with the Americans, it must be incomparable, people have invested funds in place in all aspects, the aviation industry has a long history, and as the boss of the same industry on the whole earth, it is definitely not a joke, and the powerful heritage is that the republic cannot envy it anyway.

"It's definitely not comparable to the Americans, but we can refer to a lot of things, such as the F16A fighter that is highly consistent with our new Jel, and the F100 engine it uses is also a little more than eleven tons of maximum afterburner data, so our new J can actually accept engines of the same thrust level, anyway, it's only an early model, isn't it?"

It can be seen that in order to be able to do a good job of the new annihilation, Chief Wen compared many international fighters of the same level, which can directly point out the problem that the thrust of the F16A fighter engine is only 11 tons, and the thrust-to-weight ratio of the F100 engine is as high as 8, which is naturally ignored magnificently.

"The F100 engine is currently the world's most advanced military high-thrust turbofan, although it has only 11 tons of thrust, but it can't stand the high thrust-to-weight ratio of others, so we still don't want to compare in a short time, there is no harm if there is no comparison. Wang Zhengguo looked very open, and he was half-joking when he spoke.

When the chief engineer heard the witty words, he suddenly felt much better: "You are right, but we can't just raise the morale of others, if you go back and compare the current international arms sales market with the F16 and the F16 French Mirage 2000 fighter, what do you think of the power of this aircraft?"

For the power of the French aircraft, the country has a relatively real survey, the Air Force test flight Mirage 2000 for several years, back to the review of the fuselage design and J-8 fighter between half a pound and eight taels, although this is a little not good, but the fact is so.

In later generations, when domestic military fans talked about French military fighters, they all had a sneering attitude, in fact, since the Air Force's evaluation of the Mirage 2000 in the eighties, the roots have been buried.

Speaking of which, when someone pretended to be forced in the forum, he also belittled the French machine, and now he has not changed his true colors, almost with a contemptuous expression on his face, and responded very confidently,

"The French plane, the M53 single-rotor turbofan of the Mirage 2000, is simply an oil tiger among oil tigers, this kind of engine really has nothing to praise, and the radar aperture is so small that it is ......."

No, I feel bad before I finish speaking, the sequelae of complaining about the French aircraft all day long in the past are coming, and now it may be reasonable to say that the French engine is general, but if you want to talk about the French radar, people are now the world's top goods, but it is not an existence that the role of the Republic can despise.

Quickly changed his words: "However, the French machine actually has its advantages, such as the modular design of the M53 engine is very good, and the reliability and maintainability are at the top level, so it still has a certain reference significance and competitiveness, although its overall level is not as good as the F100." ”

Quickly back to the engine, for the M53 this strange engine, people are generally at a standard of use, can make the Mirage 2000 meet the design requirements, then it is a successful product.

Chief Wen was a little suspicious of why Wang Zhengguo had some opinions about the French radar, but when he thought that what he said was only about the radar aperture, and then thought about it, it seemed that the radar aperture of the French aircraft was indeed quite small.

"That's right, the M53 engine is very average, and the thrust provided is not large, not even up to the ten-ton level, but it is still available on the advanced fighter of the Mirage 2000, so why can't our new J-J initial power system accept a power system that is similar to the M53, or even better?"

After going around in a big circle, and finally getting to the point, Wang Zhengguo seems to have grasped the key thing at this time: a turbofan engine of the same level as the M53, which in the world, except for Spey 202, who else can be regarded as the same level?

And if you ask to say Spey 202, it is obvious that this can explain why Mr. Wen advocates the use of turbofan engines as the early power of the new J, because there are relatively mature engines to choose from in China.

Spey 202 is also the same level as M53, and the country has also spent money to introduce related technology, another J-7 fighter under development also uses this engine, if the new J-202 early model uses the domestic model of Spey 202, it must be able to more directly promote the localization of this engine, with the original formal technical support, which is much easier than closing the door and reversely copying the Soviet turbotze-spray engine.

Figured out that Chief Wen was originally playing the idea of Spey 202, Wang Zhengguo didn't know whether to laugh or use other expressions, even if according to the domestic situation, it was indeed a safe choice to suggest that the new J use the more reliable Spey 202 at this time, however......

However, where is the situation so easy to explain, the water in it is still very deep: "I understand, you must recommend using the domestic Spey as the initial power system, but the problem is that the thrust curve of Spey and the vortex engine are completely opposite, probably considering the positioning requirements of the army for the new J, this is also a problem!"

Wang Zhengguo's words are obviously reasonable, after hearing this, Chief Wen smiled bitterly, obviously guessed three of them, the reason why the high-level did not agree with this plan, in fact, is because of the positioning of the new J, it is simply to require an interceptor with maneuvering ability, in this case must choose the vortex spray machine.

"You guessed very accurately, indeed from the needs of the army, the initial model of the Spey engine of the domestic model is not suitable, with a turbo spray machine can make the new J have good high-speed performance, according to the military plan, the initial model of the new J focuses on air superiority volley, so the use of vortex spray, the subsequent model to expand subsonic multi-purpose, so a high-thrust turbofan engine is planned. ”

Or is it the first time you have heard such a statement, and you actually plan to make the new J-1 the existence of one aircraft and two models, and realize different combat missions by installing engine types with different thrust curves?

Now Wang Zhengguo must say that the air force has a very flexible mind and knows that the current plan for the development of military aircraft models is not easy to come by, so it makes full use of resources and wants one machine and two types; knowing that the domestic engine industry is weak, it is necessary to arrange two engines in case of emergency.

Listen, what a good plan, this is obviously a product of the difficult environment of the early eighties, and in the case of the time, this one-machine, two-type plan was clearly the best choice.

After all, no one knew at that time that the Republic would be able to obtain world-class heavy air superiority aircraft in another five or six years, and no one even dared to think that as a homeland defense air force, a large number of small and medium-sized fighters were the historical choice of the Republic.

Besides, the bomber that does the dirty work is already under development, and at the same time, there is no need to develop another aircraft that licks the ground and pays attention to the flight qualities of subsonic at medium and low altitudes, which is a waste.

It can be regarded as solving a historical mystery, and only in this way can Wang Zhengguo be fortunate enough to know why in the 80s there were some strange choices in the eyes of future generations, a fighter positioned in the future chose a vortex engine as the power, which is still forced by the times after all!
