Last year, in order to solve the problem of the nose counterweight of the J-7, and also to thoroughly understand the technology of the J-7, the 132 factory funded the 618 Institute and the Western University of Technology to carry out the contract of "J-7M Stable Quality Calculation" and "Cancellation of Counterweight Relaxation of Static Stability Control Law Calculation".

In the past, due to the replacement of new avionics equipment, the performance was improved, and the dead weight was reduced, which was a good thing, but because the J-7 was not completely thorough, the design of the center of gravity could not be changed, so it was forced to adopt a simple solution, how much to reduce the weight, then how much to increase the counterweight, so that it is okay.

Although the problem of shifting the center of gravity backward was solved, the weight loss did not bring any benefits, so, affected by this problem, Tu Lao finally made up his mind to pay for the solution of this problem, and everyone made a careful calculation of the J-7, so that it could be solved.

After removing the counterweight, the center of gravity moves back, so that it will become static and unstable, now, after calculation, you can also make the aircraft have enough handling quality, this is a great success, in the aircraft to remove more than 100 kilograms of counterweight, it will make the performance of the aircraft stronger.

Now, this result is coming so fast!

At this moment, Qin Feng saw Tu Lao from the production line again, Tu Lao was busy negotiating during the day, and now he is still paying attention to the situation on the production line, after all, there are a lot of orders, and only by delivering products with quality and quantity can he lay a good enough reputation foundation for himself.

"Tu Lao." Qin Feng shouted, Colonel Salim on the side was also very happy, the negotiation matter was put aside, and he still had a lot of respect for Tu Lao, a technical expert.

"Well, Colonel, welcome to our visit." Tu Lao said: "The fighter here is produced for you. ”

Although everyone is noisy on the issue of the J-7 CP, the Pakistani side is quite satisfied with the J-7M fighters, and what is being produced now is the new fighters equipped for them.

At their request, this batch of fighters has been replaced with Martin Baker ejection seats, which is also one of the biggest improvements of this batch of aircraft.

"Oh, it's our plane." Salim was happy: "I really wish that the production of fighters could also be carried out in our country, and every time I come here, I look at the assembly of fighters with envy on the production line." ”

Although there is an unpleasant thing today, however, they are in order to develop the aviation industry in their country, and this has not changed.

"yes, we'd like to see that too." Tu Lao said: "The first batch of fighters you are equipped with have been in operation for a while now, is there anything that needs to be improved?" ”

If it was before, hearing people chattering about such changes, then if you change it, everyone will frown, just give it to you, where are there so many things!

This is the typical Soviet idea, the fighter plane is built, and the pilot is allowed to adapt to the fighter.

But now, it's different, everyone has changed, it's not the pilots to adapt to the fighters, but the fighters to adapt to the pilots, if there is anything bad about the fighters, then it has to be improved, the Pakistan Air Force is the most demanding, and many of the opinions they put forward are to improve the combat effectiveness.

Now that the other side has been equipped for some time, is there anything else that needs to be improved?

This is also the need of market competition, and only by building new fighters that suit the market can they continue to develop in the international arms market, otherwise they will be eliminated.

"If there's one thing that needs to be improved, it's the steering stick." Salim thought for a while and said seriously: "When our pilots are operating, they still feel that when the steering stick is operating, it is not particularly smooth, and it is easy to get tired after a long time. ”

The comfort of the joystick is very important, which helps the fighters to further complete the combat mission, and now, this is also summed up after a period of flight, shortened, it is more convenient.

"Anything else?" Tu Lao recorded it carefully, and then continued to ask.

What else?

"It's still a plug-in ability." Salim continued: "Continue to increase the strength of the pylon, increase its load capacity, the more the better. ”

For them, the pursuit of large auxiliary fuel tanks, the number of missiles, is endless, and if possible, the payload capacity must be increased.

Increasing the number of auxiliary fuel tanks, which can increase the time of air stay, increase the number of missiles, and improve the combat capability when performing tasks, are what they are most looking forward to.

"yes, let's continue to improve, we can only continue to think of a way from the wing fuel tank." Tu Lao said. Expand the overall fuel tank of the wing a little more in order to increase the fuel storage?

Tu Lao was pondering, Salim looked at the busy scene in the workshop, and said, "These fighters, not all of them are produced for us, right?" ”

"Of course not, the final assembly line over there is a J-7M fighter produced by our own Air Force." Tu Lao said.

Our own Air Force! Hearing this, Qin Feng also felt a burst of excitement, Jian-7M, this fighter was originally for its own use, but the Air Force didn't want it, and now, a large number of them have been exported, feeding the entire enterprise, and at the same time, the Air Force has also begun to eat grass.

The Air Force also ordered a batch!

In fact, according to the number, the export is called the F-7M, this F can have a variety of understandings, if it is according to the American naming method, it is the meaning of the fighter, and according to its own Chinese pinyin, this is a flying word, in short, this is the number of the export.

For personal use, it is called J-7M

After discovering that this aircraft is good, the Air Force will also order it, but the Air Force has just begun to operate, and among the pilots of the Air Force, there are too few who are familiar with the operation of the head-up display, otherwise, it will be much easier for their new fighters to select pilots.

Qin Feng was still thinking about the test pilot of the new J, there was no way, this was always Qin Feng's greatest concern.

No matter how J-7 is changed, it is impossible to jump out of the framework of the second-generation aircraft, when he saw the chic attitude of the MiG-29, Qin Feng has a sense of urgency, the domestic research and development of the new J-1, it is urgent to wait, as a test pilot, to be able to fly the third-generation aircraft, is a thing to look forward to.

"It would be nice to be able to fly an F-16 and find out how it feels." Qin Feng let out this exclamation, and in the face of Qin Feng's proposal, Salim had a smile on his face: "Perhaps, we can find an opportunity." ”
