"I'm back." Qin Feng finally returned to Chengdu, after he got out of the car, he breathed the humid air here, and had a unique feeling, this time he went out, and after such a long time, he finally came back again.

However, after Qin Feng came back this time, he did not go to the 611 Institute as soon as possible, but came to the 132 factory first, and after walking into the factory, he saw Tu Lao.

Tu Lao was very happy about Qin Feng's arrival, and when he saw Qin Feng, Tu Lao's frowning brows were already relaxed: "Qin Feng, you are finally here, I thought you would have no time in the future." ”

"I've been in Shenyang for a few months this time, and I'm very touched, Tu Lao, do you know the turbojet-14 engine?" Qin Feng came to find Tu Lao, of course, for the Jianqi CP project, and he couldn't wait to remind Tu Lao.

The power of the turbojet-14 engine can be increased by 20% compared with the turbojet-13, and if the J-7 CP is replaced, it will solve a big problem.

Hearing Qin Feng's words, Tu Lao had a smile on his face: "This, of course I've heard of it, but you also know that we can't stand on a project that has just started trial production, so it's easy to delay the entire project." ”

Of course, Tu Lao had heard of it, but he had never included the Turbojet-14 in the plan under consideration.

Turbojet-13 is the engine of the overall mapping imitation MiG-21MF, just the mapping imitation, it took a lot of effort, tossed for several years, and now the test run has begun, as long as the material is passed, there will not be too many problems.

However, the turbojet-14 is different, this kind of engine is developed by itself, Tu Lao feels that putting the J-7 CP on this project is a bit hanging.

Qin Feng heard Tu Lao's words, and understood in his heart, it is indeed not reassuring, just like the turbofan six, he went to the test bench and worked on it for so many years, but in the end he did not mature it, and now the turbojet-14, I am afraid that it will also encounter such a result.

In the final analysis, the domestic scientific research force is too weak, especially in terms of aero engines, even worse, the country has not gone through a complete successful model, relying on patchwork, it is estimated that it is enough.

"When I was in the test flight institute, I saw the flight show brigade of our air force, and until now, they are still equipped with Jianjiao-5 fighters as flight demonstration aircraft, I think that we can't show the strength of our country, if we can replace them with J-7C, it would be good."

According to the plan, this kind of aircraft was originally intended to exist as an advanced low-altitude combat fighter, and it did not require a high maximum speed, but the maneuverability must be good.

In terms of international cooperation, the F404 engine will be replaced and avionics will be improved on a large scale, but if it is developed domestically, these may have problems.

On the other hand, it is the engine, if the turbojet-14 engine is replaced, the engine problem can also be solved, so that an advanced aircraft is prepared for the air show team.

But now, after hearing what Tu Lao said, it seems that this idea is destined to fail.

Tu Lao knew what Qin Feng was thinking, and now, listening to Qin Feng's words, a smile appeared on Tu Lao's face: "As for this problem of mobility, we have already begun to study it, do you remember when we asked the Western University of Technology to jointly carry out the problem of thorough calculation of the Jianqi?" ”

Of course Qin Feng remembered, at that time, it was a tripartite alliance, and the Jian-7 was thoroughly eaten, just to remove the counterweight of the Jian-7, so that the Jian-7 could achieve more advanced performance, and now, it has been realized?

"This contract, we have completed, they have done it very well, we are planning to do a new modification of the J-7, this modification, can completely remove the counterweight of the nose." Tu Lao said.

J-7 has been improved to J-7M, this aircraft has been reborn compared with the original MiG-21, and even the domestic air force has taken a fancy to it and began to order.

However, the 132 factory can not sleep on the results, they must continue to improve, develop, after all, they to the world's advanced level there is still a big gap, now this is the case, they know that their aircraft still has a lot of shortcomings, that is, to improve these deficiencies.

"So, next, are you going to do the ACT model?" Qin Feng asked.

According to the plan, the last time we discussed changing the ACT, through this active control, the aircraft can have more powerful maneuverability, if this technology is adopted, it will definitely be a pretty good aircraft for the air show team.

Tu Lao shook his head: "We don't have that plan, the domestic reserves are not enough, we want to develop such a model, it costs too much, and it is not something that our factory can afford, and we still have a CP project, and the improvement of the J-7 can only be partial." ”

Factory 132 is just a research room in the factory, the technical force is limited, but it is not a special research institute, and the foreign J-7 Cp project, it has involved too much energy, if you want to go to the J-7 ACT project, there is absolutely no energy, and there is no financial resources, the project in Shenyang, which is funded by the state.

"If Tingting can come, maybe we can make her the leader of our ACT program." Tu Lao said.

When Tu Lao said this, Qin Feng could only smile bitterly, and he changed the topic: "Then what do we want to change?" ”

"Double delta wings." Tu Lao said: "We have joined forces with Professor Sha of Xi'an University of Technology to calculate the improvement of the wing of the Jian-7 many times, and now it is basically determined, as long as we blow the wind tunnel a few more times, we can enter the manufacturing process." Tu Lao said: "Now, we just have to grasp both hands." ”

Qin Feng also participated in the discussion of the double delta wing at that time, but later, Qin Feng forgot about it, after all, when it came to Factory 132, Qin Feng always thought about the Jianqi Cp, and he really didn't think too much about anything else.

Now, Tu Lao said this improvement project, we can improve the mobility of the J-7, and now, we can change a little bit!

Compared with the J-7's current simple large sweep delta wing, it has been changed to a double delta wing, with a sweep angle of 57 degrees on the inner wing and a sweep angle of 42 degrees on the outer wing.

The nose of the aircraft has not changed, and it still does not have over-the-horizon air combat capabilities, but in terms of close-range combat, it is already able to match the F-16.

"Okay, when are we going to start?" Qin Feng said: "If I'm still in Chengdu, then let me fly!" ”

The maneuverability of this kind of aircraft has been greatly increased, and it can also be reequipped for the air show team.

"Now, let's wait for the Turbojet-13."
