These are all brought out of the mother's womb.

From the J-5 era to the current J-8, everyone is copying the MiGs of the Soviets, and when the landing gear is deployed, the support point is in the middle of the wing.

In this case, the distance between the wheel base between the main landing gear can be maximized to maintain the stability of take-off and landing, after all, the fighter is like a tricycle and is unstable.

At the same time, now in the Western world, the landing gear has begun to be popular, the support point is not on the wing, but on the fuselage, when recycling, it is directly recycled into the fuselage, so that the precious space under the wing is set aside.

A fighter like the F-15 can have eight or nine pylons outside, and you can even get on composite pylons and hang as many as you want.

The J-7 is not good, the only thing that can be used by the current J-7 is the space in the outer section of the wing, which is not cut into two sections by the landing gear, and can be mounted.

"This fighter uses an outdated turbojet engine, with high fuel consumption and short range, and in order to increase the range, it is necessary to mount the auxiliary fuel tank." As an insider, Lusadi said very well: "In this way, it is necessary to increase the hardpoint of the wing, and the hardpoint of this wing must have a payload capacity of at least 500 kilograms, which can carry a 500-liter auxiliary fuel tank, rockets, bombs, and pylons on the outside, which can carry air-to-air missiles." ”

Under the fuselage, you can mount 800 liters of auxiliary fuel tanks, and under the wings on both sides, you can hang 500 liters each, so that it is barely enough, and, once necessary, rockets, bombs, etc. can also be hung on the wings, so it is absolutely impossible to add pylons now.

However, if you want to add pylons, the wings will have to be redesigned.

You must know that what Jordan requires is not only to be able to hang a magic missile, but also to be able to hang a drop fuel tank, and to have a bearing capacity of 500 kilograms.

In this way, the internal structure of the wing must also be reinforced, and the strengthened parts must be strengthened to calculate the force and meet the loading needs.

In this way, the amount of work to change is getting bigger and bigger.

Suddenly, Tu Lao thought of something, this payload capacity has increased, it can be said that five hundred kilograms are added on both sides, that is one ton, in this case, the landing gear must also be strengthened, otherwise when landing, the landing gear will be at risk of breaking.

In this way, the complexity is even greater.

Tu Lao frowned, this is a huge challenge for his side, up to now, he has not introduced Marconi to the other party's head-up display equipment, the other party has already put forward so many suggestions for improvement while visiting the factory and the fighter being assembled.

Insider, definitely insider.

The ejection seat, Tu Lao can insist, but the other improvement ideas proposed by the other party are all reasonable, and he can't refuse, if he refuses, this business is estimated to be enough.

"We will discuss these improvements in detail later." Tu Lao said: "Now, we also want to introduce a new equipment to you, and now, we are planning to install modern fire control equipment on the fighter to achieve flat shooting, which will double the combat effectiveness of the original fighter." ”

Since the other party has put forward so many opinions, it shows that he knows a lot about fighter jets, and now, listening to what Tu Lao said, sure enough, the other party is very interested.

The current fighters of the Soviets have not yet achieved the flat display, they only achieved the flat display shooting on the MiG-29, and the electronic system is a grade behind the West, and now, the 132 factory wants to add a flat display to the J-7, which immediately attracted the attention of Lusadi.

At this time, everyone has walked around the production line, and at the end of the plant, entered the office area and entered the conference room.

If there were enough equipment now, they could experience it for themselves, but alas, they still have to dictate it now.

When he came to the conference room, Tu Lao's preparation was very sufficient, he closed the curtains, turned on the slide projector, and began to play the slides.

"The biggest advantage of the head-up display is to save time, so that the pilot does not have to look down, can grasp the main flight data, we cooperate with Marconi to jointly develop a head-up fire control system suitable for J-7 equipment, this is its block diagram."

One slide after another, they began to be put up, and the Jordanian guests listened attentively.

Finally, when the lights came on again, Lusadi spoke: "In other words, if this system can be developed, it will greatly improve the performance of the fighter?" ”

"That's right, that's it, we believe that Pingxian is the hope of future air warfare."

"But what if the development of this system fails, or if the progress is too slow?"

"With Marconi technology as the foundation, how can the research and development fail? As for the progress, if you urgently need fighters, we can now produce them according to the existing standards, export them to you first, and wait until this system is completed, and then produce the fighters in the later stage according to this standard, and the early models can also be upgraded to the current standards, how about it? ”

These are all things that everyone has come up with a long time ago, Tu Lao looked at Qin Feng who was sitting in the corner, although Qin Feng has been acting in obscurity, but Qin Feng has a lot of credit for the planning of this plan, especially the current answers, which are all questions that Qin Feng may ask the other party.

R&D will not fail, at most it is a delay in progress, there is no need to be afraid of progress delay, use the current model in the early stage, and improve it in the future.

"We need to think about this before we can answer it." Lusadi said.

After all, before they came, they didn't think about improving avionics, and it was a Western avionics, if it was changed, it would definitely cost more money, and they had to be cautious, and there were no mature examples, they were the first to test the waters, so they had to be even more cautious.

"Everyone, the journey is hard, today's investigation, that's it, let's go to dinner." When the comrades of AVIC saw this situation, they immediately changed their minds.

Originally, here in the afternoon, there was another air show, it seems, forget it, these Jordanians, put forward more and more opinions, if you continue to stay, watch the air show, you may still put forward opinions, why does the engine emit black smoke, how big is this maneuver overload?

Simply, take them to eat, drink and have fun first, and make them happy first!

"Yes, all the guests have come from afar to taste our Chengdu food!" Tu Lao also breathed a sigh of relief and sent them away, he had to hurry up and make a calculation to see if the conditions they proposed were feasible.
