Waiting for the Turbojet-13, it is not only the new project of the current Jian-7, but also an old project, which has been waiting for a long time!

In Factory 132, Qin Feng saw the Jian-7 3 in the assembly workshop, and now, in the face of this kind of fighter, Qin Feng also felt speechless for a while.

How many years?

When I first went to Egypt, it was a long time ago, Qin Feng at that time, who had just participated in the test flight work, followed to test the MiG-21MF, and once flown it, this kind of big-nosed aircraft looks so ugly, I am used to watching the domestic J-7, and then look at this, I feel like a monster in a cartoon.

Now, in the workshop of the factory, Qin Feng saw this kind of aircraft, Qin Feng saw that this kind of aircraft had been assembled, and it stayed quietly in a corner, but the fuselage and tail were separated, the tail was empty, and the engine inside was nowhere to be seen.

"Old Song and them, this Jian-7 3 project is also impressive." Tu Lao took Qin Feng to the workshop, saw the plane here, Tu Lao was a sigh, back then, Tu Lao had some conflicts because of the problem of surveying and mapping or eating thoroughly, and later, handed over to Song Lao, according to his ideas, went through the whole design process, and was considered to have eaten the technology.

The result? It has dragged on for several years, and it has been dragged to the point that the superiors do not want it at all, because the development of the situation is very fast.

At that time, there was no domestic fighter that could have over-the-horizon combat capability, and the biggest feature of this imitation MiG-21MF fighter was the addition of an air intake cone, which could accommodate a small radar, so that the fighter had the ability to guide medium-range bombs.

But what about now? J-8 has been changed to air intake on both sides, which can have enough space to accommodate large radars, and J-7 is also carrying out the plan of the J-7 CP project, this project will also be air intake on both sides, leaving the nose to install radar, in this way, it is definitely much better than the J-7 3 of the air intake cone radar.

The size of the radar added to the air intake cone is limited, and the caliber can be 500 mm, which is already against the sky, but what about the J-7 CP, it is no problem to add a 700 mm one, and the performance must be stronger.

Moreover, because it is in the inlet tract, the echo reflection formed by the lip of the intake tract has always been a big headache, so to speak, and now it is chicken ribs.

It is a pity to abandon the tasteless food, after all, the country has spent a lot of effort and invested a lot, at the beginning, the body has been cut, and it is wasted if it is not produced.

Now, it's all here, the fuselage is assembled, and it's just waiting for the engine.

Because of the design of this kind of fuselage, the engine is stuffed in the middle, so the fuselage and tail are separated, this method has made the Pakistani side criticize a lot, and it must be improved, but if it is improved, this is definitely a big project.

"We've been in contact with people from GE a few times, and they promise that their engines are very reliable, and they basically don't need to dismantle them several times during the whole life cycle, so they think that the problems raised by the Pakistani side that will be opened later can be ignored." Tu Lao looked at the tail of the plane, and what he thought of was still the Jian-7 CP project.

The Pakistani side emphasized that it should open its mouth and push directly from below, but if it is done in this way, the rear fuselage may have to be redesigned, which is a big project.

Now, General Electric has patted its chest, and now this is no problem, because the reliability of people's engines is very high.

Qin Feng nodded: "Yes, the gap between our engines is too big, will we install the turbojet-13 when the test run is completed?" ”

Tu Lao's face was a little serious: "Yes, there is no other choice but to install it on this kind of plane for a test flight." ”

J-7 3 is new, turbojet-13 is new, these are the first time, test flight is actually very dangerous, if it is more safe, should be installed turbojet-13 on a twin-engine fighter, such as J-8, while loading turbojet-7, while installing turbojet-13, such a test flight will be more secure, many new engines, are tried out in this way.

However, there is no time in Shenyang, and people don't match, so here we can only test the new machine with a new engine.

I guess it's about the same next year.

This kind of aircraft, in order to increase the fuel tank, deliberately increased the back, which bulged in the back, blocking the sight of the entire pilot's rear, and at the same time led to a further decrease in maneuverability, which also made the plane appear even more ugly.

"I was in the test flight institute and suggested that they study air refueling technology, and our aircraft can only have the possibility of air refueling if it is changed to J-7 CP, right?" Qin Feng asked.

Tu Lao shook his head: "We haven't considered this yet, this meal has to be eaten bite, and the work has to be done little by little, and now we really can't take care of it." ”

The J-7 CP project has exhausted Tu Lao, and the negotiations with Marconi were protracted, and now the negotiations on the J-7 CP project are progressing even more slowly.

"On the American side, are you still talking about it?" Qin Feng came here, in fact, mainly for the Jian-7 CP project.

It's really hard to negotiate with them, and if you are a little careless, you will be taken into the ditch.

"Now, we are talking about TAA, which is a technical assistance agreement, an agreement by the Americans, and now, as everyone knows, the Americans want to make money, and they are afraid that we will acquire technology, these are the key points, and it is estimated that it will be soon, and these negotiations will be completed, and we will go to a group of experts, who will be resident there, and promote this project." Tu Lao said.

"Tu Lao, I don't understand a little." Qin Feng was thinking about this problem all the way, and now in Tu Lao's place, he finally said it: "Our J-7 CP is Pakistan's Sabre project, the Americans have been guarding against it, and they are afraid that we will get any technology, what F404 engine, what advanced pulse Doppler radar, but on the other hand, Shenyang has decided to send the J-8 to the Americans to improve, the radar has been selected, the engine, they are also highly recommending the F404, they are not afraid that we will get the technology?" ”

The contrast between these two projects is too great, and they are both carried out by Grumman, and they are both in charge of Pelehak, why do he have two completely different attitudes.

"Yes, we are also very strange, it is estimated that the difference between the two projects, one is that they are purely making money, and the other is that we want to make more money." Tu Lao said.

Americans, in the final analysis, are all about making money. Dealing with foreigners a lot, Tu Lao can be regarded as understanding, they are also studying the laws of the United States, how to bypass the law, reach an agreement and so on.
