In the past, the Sukhoi Design Bureau did not have anything to do with it, but when the Su-27 came out, it really amazed the audience.

Especially at the Paris Air Show, this beautifully shaped aircraft, after its appearance at the air show, shocked the whole world, and now, putting down the newspaper, Qin Feng found the special Paris Air Show journal at that time, which contained a large number of reports, all about this aircraft.

The Soviets did a very good job of secrecy, unless the Soviets themselves declassified it, otherwise, the outside world would not know about their secrets, and many of the articles here are speculation, but there are also many merits.

After Qin Feng opened the periodical, he looked at the color picture on the title page, this color picture is the incomparably beautiful Su-27!

According to a lot of public information, they use the scientific research results of the Moscow Central Fluid Design Institute, the side wing, the wing body fusion, the whole aircraft, is a huge lifting body, from this plane, you can not see the nose, fuselage, the obvious dividing line of the wing, the whole aircraft, is one, this smooth shape, but also reflects the highest achievement of the Soviets in machining, you know, this special-shaped, processing is also quite difficult.

Although it looks similar to the MiG-29, if you compare it carefully, you can tell it.

The Su-27 fighter has a larger fuselage, so, in the same configuration, it appears more slender, compared to the MiG-29, it is more durable, the position of the optoelectronic device in the nose is different, there are pylons at the end of the wing, and, in the rear fuselage, the distance between the two engines is wider, there, there is an additional rear tail vertebrae.

Now, Qin Feng looked at this title page, and couldn't help but touch it twice, when will he be able to have such a beautiful plane!

It is different from the beauty of J-10, J-10 is a duck-like shape, it looks like a small jasper, and this Su-27 has a huge shape, more like a lady's show, and like an eagle.

Flipping back, Qin Feng read its design information again.

This kind of aircraft, the air intake is short, the belly air intake, you can see the bulge of the air intake and the engine behind it, the whole look, it is like the power unit embedded in the fuselage, which also reflects the designer's skills, so beautiful.

This information was in English, so Qin Feng could understand it, and he read it carefully again.

A lot of data is conjecturical, after all, the Soviets will not leak their secrets, but there are also some that are marked on it, reflecting the development of the Soviet Union in military science and technology.

Like, its engine.

In the past, most of the engines of the Soviet Union were also turbojet engines, after all, this was the original engine structure, however, with the development of the times and the progress of technology, it is inevitable that turbofans replace turbojets, and on the third generation of aircraft, turbofan engines are needed to provide power, and the engine of the Su-27 fighter uses the AL31F engine of the Rurika Design Bureau, and this engine is designed with various indicators aimed at the F100 series engine.

For example, its maximum thrust exceeds 12 tons, and F100 a level, under such a strong thrust, the Su-27 has reached the thrust-to-weight ratio of the whole aircraft more than 1 index, and the fuel consumption rate has decreased greatly compared with the previous turbojet engine, and the large range of the Su-27 exceeds that of any previous Soviet fighter, which is also given by this engine.

31F, 31F, this voice, how does it look like a third aunt? Qin Feng silently recited in his heart: "Well, it's good to call the third aunt, this engine, with a thrust of 12 tons and a thrust-to-weight ratio of 8.17, of course, this standard is calculated according to the dry weight standard of the Soviet Union, the engine of the Soviets does not add oil, plus various lubricants and the like, according to the standards of the West, it will be reduced to 7, but even if it is reduced to 7, the data is still good." This kind of real high-thrust engine can only be produced by the two superpowers in the world, the Soviet Union and the United States. With a diameter of 1.3 meters, it looks big enough, and the turbine front temperature is as high as more than 1700 drives, and in terms of technical level, it is definitely a third-generation aircraft! Well, the data is better than your own turbofan ten. ”

Wait a minute!

Qin Feng suddenly thought of something, the third uncle, the turbofan ten, it was very similar! Isn't this kind of engine, if it is installed on your own J-10? The J-10 fighter is now continuing to be developed, but, listening to the words of Song Lao a few times ago, he does not plan to install the turbojet 15, if he uses the turbojet 15 to test the flight first, then in the future, when the turbofan ten comes out, when the equipment is changed, there will be a lot of trouble, and Song Lao is looking forward to the turbofan ten coming out.

However, the development of an advanced turbofan engine is not an easy thing, Qin Feng is not so optimistic, thinking that the turbofan ten can be developed quickly, according to the progress of foreign countries, the research and development time of the engine is significantly longer than the research and development of the fighter, and the research and development of the two at the same time, or even the research and development of the engine is later, it will definitely not be able to catch up.

If you import F100 from the West, on the one hand, it is quite expensive, and on the other hand, it will be stuck at any time, as if your own cooperation project has been suspended.

The Air Force cannot afford to accept this risk, but since the window for cooperation with the Soviet Union has been opened, what if the Su-27 fighter can be introduced, and at the same time, this engine can be introduced and matched to the J-10?

Just like the American F-15 and F-16, they all use the same engine, if we introduce the Su-27, develop the J-10 ourselves, and then use the same model, will it greatly reduce the complexity of logistics?

The third uncle, it's really good, but it's just a blind thought, this kind of plane must be very valuable, the country estimates that it can't come up with so much money, and even if you want to buy it, the Soviets will definitely refuse to sell it, and the Sukhoi series of aircraft have always been for their own use.

Qin Feng pondered for a long time, and finally closed it, now, it is useless to ponder these by himself, after all, he is just a small test pilot, and now he is testing the J-7, which is already the most advanced fighter in China, and the second-generation Spey engine is also used, and the aerodynamic layout of the airframe is also the appearance of the second-generation aircraft.

However, when I saw the Su-27 fighter on the title page, I couldn't help but stare at it, and when it made the Cobra maneuver, it was absolutely amazing to the audience, because of the test flight of the J-7, I didn't have time to go out, if I could go to Paris to see this air show, how lucky it would be.
