The overall life of the body is caused by many factors, we must analyze the impact of each factor, consider the overall situation, and constantly improve the shortcomings in the bucket effect and improve the life of the entire body.

The original idea was to change the nose of the J-7M, and change it, so that it could become a new type of fighter for export and seize this low-end market.

However, with the increasing demands of the Pakistani side, not to mention the major changes to the front fuselage, even this rear fuselage is impossible to take and use, and under such continuous changes, it is almost the same as developing a completely new aircraft.

Don't take off the rear fuselage, tail blocking hook, overall life extension, this means that the rear fuselage has to be changed on a large scale, the front has not been completely determined, and there are a lot of problems in the back.

"The fuel capacity of the aircraft should reach 4,000 liters, which is a hard indicator that we recently proposed, and at the same time, the overall windshield and bubble-type hatch cover are all we have mentioned before, and these must be clear, and the following needs to be British ejection seats, and the pylons under the wings must continue to increase." Lieutenant Colonel Mirza kept saying one indicator after another.

This new aircraft, negotiation, is very difficult, the other party has more and more requirements, and they must also follow the customer's opinions, so they need to constantly change the design, and the amount of tasks is also increasing.

Such an improvement, relying only on the design institute of the 132 factory, is estimated to be very choking, if the time drags on, it may make the whole project finally yellow.

Everyone's hearts are heavy.

"The last requirement, this kind of aircraft, must have a corresponding two-seat trainer aircraft." When this request was spoken, Qin Feng blurted out: "This training aircraft, we are already developing the J-7 training aircraft, the new aircraft is a modification of the J-7, maybe, we can complete considerable training directly on our J-7 training aircraft." ”

If you change the training aircraft again, then you can't finish it no matter what, others are not sure, Qin Feng can also be sure.

The two-seater trainer aircraft, don't look at just adding a seat in the back, but there are quite a lot of changes, and the amount of work is very large.

"J-7 has a trainer plane?" Lieutenant Colonel Mirza was very curious: "In this case, we can really inspect it as soon as possible, import a batch, and now, the army is modified J-7M, and there is a lack of training aircraft!" ”

When Pakistan imported J-7, it went through a cumbersome process, and the 132 factory went through countless difficulties before finally winning the project, and the plan of the J-7 CP was even more rugged, but on the J-7 CP, Pakistan surprised everyone, just like going to the vegetable market to buy Chinese cabbage, after an inspection, I decided to buy it, which was too efficient!

Because they really need it.

"Can we go and investigate now?" Lieutenant Colonel Mirza was interested and asked this question.

Now go to investigate, the J-7 trainer has not yet flown up!

"Or will we do it next time?" This stubble was provoked by Qin Feng, of course, Qin Feng must be asked to solve it: "The J-7 trainer aircraft is not here, but in the aircraft factory in Guizhou, we can't arrange it this time, the next time you come to inspect, the J-7 trainer inspection will also be determined, by the way, when will we talk next time?" ”

In this meeting, we talked about a series of issues, in short, there was no decision, and we had to continue, both sides pondered for a few more months, and then held a meeting, we can determine the current design plan, cooperative research and development methods and the most important cost bearing and other issues.

This project was proposed by the Pakistani side, so they don't want to ask for the plane directly, they must bear the research and development funds, this project is a major facelift, it is impossible to do it by themselves, and it must rely on foreign capital.

"May or June." Lieutenant Colonel Mirza made a decision.

In May and June, there will be a few months to carry out these next coordination activities, and then the discussion will continue, and maybe next time, General Jamal will come with him, after all, this project was promoted by General Jamal single-handedly.

And so the meeting ended.

Tu Lao felt a lot of pressure, but there is pressure, there will be motivation, this project is successful, then the market will live, it can be said that now this project, can be related to the development of 132 factory in the next 20 years!

As for Qin Feng, he also had to shift his position.

"Qin Feng, life in Guizhou is hard, I'm afraid you will have to be wronged for a while." Old Tu personally came to see Qin Feng off.

In fact, after having an airplane, it is not difficult to change the two-seat training aircraft, but the side is now in the design stage, if you have to consider the two-seat training aircraft, it will be very difficult, not enough energy, this time, Qin Feng pushed the matter of the training aircraft to Guizhou, then Qin Feng will also go over, help fly together Jianjiao-7, at least before the arrival of personnel from the Pakistani side, Jianjiao-7 will complete the first flight, right?

If you can fly, let them see it, but as long as you can fly, there should be no problem.

Life in Guizhou is much more difficult than in Chengdu.

Now, hearing Tu Lao's words, Qin Feng didn't care at all: "It doesn't matter if life is hard, it's just that I'm going to leave Chengdu for a while, so I won't say goodbye to Song Lao, you can take the time to convey it to me, I am also looking forward to the victory of Project No. 10, and I look forward to flying our new annihilation." ”

Qin Feng is most concerned about Project 10, hoping to fly his own advanced fighter jets! Now, the plane has always been on the drawings, and he used to be of little use.

How many years is it for an aircraft to be designed and finally equipped with troops?

Now everyone has not realized that this marathon, the J-10 took 20 years, and this J-7 modified fighter, before and after, went through ups and downs, and even took 20 years before finally waiting for the final service.

Qin Feng left Chengdu and embarked on a new journey, Guizhou, which is an equally ancient land, where there are Paleolithic cultural sites, as early as 240,000 years ago, Guizhou has human habitation and reproduction, and now, Guizhou will also enter a new era of vigorous development, Guizhou's aviation industry, is also about to usher in a new take-off because of the Jianjiao Seven Project!
