Qin Feng has not been to Shenyang for many years, all these years, Qin Feng has been busy with the test flight of the J-10, autumn to winter, year after year, he just heard that the Su-27 production line has been introduced here, and the assembly of the Su-27 fighter has begun, but he has never been here.

This time, it finally came, and it was piloted by the T-10K-3 prototype and flew to Shenyang, after all, if you want to map and copy this aircraft, it must be carried out here in Shenyang.

When the wheel fell lightly on the ground, Qin Feng also felt very tired, came back from a long journey, and landed at a base halfway to refuel and rest, even so, it was a great challenge to physical fitness, Qin Feng only had one feeling, it was really old, if he was young, when his body was very strong, he didn't have to worry at all.

Now, when Qin Feng stepped off the plane, what he wanted to do most was to get a good night's sleep, but then, when he saw the person who came to pick him up, he couldn't help but pause.

"Grandpa?"

Mr. Gu has retired from the front line, he is idle at home, almost all his life has been spent on Jianba, this time, I heard that Qin Feng was coming over, and he actually took the initiative to come over to pick up the plane, which made Qin Feng also feel uneasy, after all, he hadn't come to visit the old man for a long time, and in the past, he had refused the invitation of the old man many times and did not stay in Shenyang.

"I thought you were going to call me Mr. Gu again." Mr. Gu was very open-minded, and said to Qin Feng: "Over the years, our Shenyang here has also undergone earth-shaking changes, our production line is more advanced than Chengdu's, do you want to take a look?" ”

Qin Feng immediately felt that all the fatigue was gone, after the introduction of the Su-27 production line here, it is said that it has been transformed on a large scale, but how to transform, Qin Feng does not know, now Mr. Gu said this, which aroused Qin Feng's interest, followed Mr. Gu and walked into the production workshop.

Su-27 is a third-generation machine, as a feature of the third-generation machine, that is, the use of titanium alloy has greatly increased, so the production line here has also introduced a large number of special equipment to manufacture titanium alloy modules.

Further back, it is gradually a finished aircraft, there is a row of Su-27 fighters, which are being assembled, and the sound of rivets can not be heard in the factory, there are already special rivet guns to operate, Qin Feng looks at the assembly of these fighters, and his heart is also surging, in now, the progress of Shenyang is also satisfactory, they already have an advanced third-generation aircraft production workshop, the production of the entire workshop is in good order, and they are working overtime day and night.

There is a great demand for J-11 in China, so after the factory in Shenyang was put into operation, production is constantly in progress, and now the time has passed the end of work, but the workers are still producing seriously, it seems that this is the night shift.

After passing the assembly workshop here, and then moving forward, the assembly has been completed, and after the test flight, the fighters can be delivered to the troops, and there are two in front of them, but they are just sprayed with primer.

Qin Feng circled around the plane, and when he came to the back of the plane, he immediately said in surprise: "The engine in the tail of this plane is not the third uncle?" ”

The plane in front of me is very strange, the engine has been installed in place, but the engines on both sides are actually different, as long as you look at the zigzag design of the convergence throttle of the tail nozzle, you know that it is different from the original third uncle, it is really strange, how can there be two engines on an airplane?

"The one on the left is the third aunt, but the one on the right is not, what the hell is going on?" Qin Feng asked.

"What do you think?" Mr. Gu asked.

"Could it be that the one on the right is the turbofan ten?" Qin Feng suddenly felt that his breathing was short, Turbofan Ten!

Back then, knowing the arduousness of engine research and development, many old experts jointly wrote a letter requesting the development of a new high-thrust engine, which is the turbofan ten, but after years of hard work, the turbofan ten still can't work, so the J-10 can't wait for the turbofan ten, so it can only be used by the third uncle.

And now, the weird engine seen here, is it the turbofan ten?

"That's right, it's too good." Mr. Gu said: "Now, Taihang has built it, and this aircraft is a technical verification aircraft we have here, which is built according to this idea." ”

J-11 is a twin-engine fighter, so one of the engines can be replaced with Taihang, and the other is still with three uncles, so that during the test flight, in case there is a problem with the Taihang engine, at least there are three uncles to ensure the safety of the flight.

Years of use have shown that the third aunt is a fairly stable engine.

"However, if we only need to change the engine, then we can find a random one, why use a new plane?"

That's too extravagant, isn't it? Wouldn't it be better to experiment with those planes in the Air Force that are nearing the end of their life?

Mr. Gu had a mysterious smile on his face: "So, you go up and have a look?" ”

For pilots, go up to see the cockpit, you can have a more in-depth evaluation of the aircraft, Qin Feng heard Mr. Gu say this, he knew that there must be a doorway, so he stepped on the gangway and went up, when he saw the cockpit for a moment, he couldn't help but exclaim: "This plane is no longer the original Su-27!" ”

The original Su-27, Qin Feng flew over, and the carrier-based aircraft that is flying back now can also be said to be an original aircraft, and the cockpit is full of mechanical instruments, which is quite ancient.

The Su-27 produced by the introduction of domestic technology is also such a standard, but now, the one in front of you is not like this.

The mechanical instrument is gone, it has become a display screen, but it is still a little smaller than the display screen of the J-10, count it, there are actually five display screens in it! Combined with the upper level display, what is this? One draw and five strokes?

This kind of layout,I really haven't seen it,Let's not talk about whether it's a big screen or a small screen,At least these layouts in front of you,It shows that Shenyang has begun to improve this aircraft。

The biggest problem of the Su-27 is that the avionics are backward, Qin Feng defeated the J-11 with J-10, but also because of its backward avionics, if the domestic avionics are fully replaced, the performance will definitely be improved a lot, since they can think of doing this, then of course Shenyang can also think of it, and they are already doing this, on the one hand, they are continuing to mass-produce Su-27 fighters, on the other hand, they have begun to improve with a big axe!
