Qin Xue doesn't know how to drink, a drink, can also express his heart, that's right, J-10 is now successfully finalized, 14 is also considered to be a high degree of hard work, without them, there will be no qualified avionics, Shenyang has been the main J-13, just feel that the domestic avionics are unreliable, J-8 has been engaged in so many years, they have long lost confidence, as a result, here, it is really successful.

Qin Feng is also very emotional, a fighter plane, not only Chengdu's own, there are so many parts and components on it, from various brother units, now it seems that Song Lao's biggest contribution is not only to develop the J-10, but also to establish a modern fighter research and development system, the previous kind of slow style in the system has disappeared, and if you can't get qualified products, you would rather go to the outside than give the green light to the system, although you have offended many people, Song Lao still insists, now, this system is down, Everyone has also adapted, which also lays the foundation for the future.

Song Lao has good intentions.

Qin Feng usually doesn't drink alcohol, but today, as soon as he raised his head, he drank this celebration wine into his stomach.

"Yang Gong, now, we're mainly engaged in the Thunder Dragon project, right?" Qin Feng asked Yang Gong.

"It's not just the Thunder Dragon, the J-10 has already succeeded, so its follow-up model will also start immediately."

Follow-up models? Qin Feng's eyes suddenly lit up: "Is it a two-seater?" ”

"That's right, now, the J-10 will immediately equip the troops in large quantities, and it is inconvenient for the troops to train without a special two-seat training aircraft, so the troops have put forward a request to us, and we must develop this two-seat type as soon as possible."

If the aircraft is not made by itself, it is quite difficult to improve, the original J-7 has experienced this kind of problem, obviously it has lost weight, and new avionics have been used, but in order to trim, it is hard to add more than 100 kilograms of cement counterweight to the front.

Everything is done by the J-10, and now it is very easy for a single seat to become a double seat.

Directly behind the pilot, a part of the space is removed, and a second cockpit is installed, and it can become a two-seater.

"If it's a two-seater, I don't think it's cost-effective just as a trainer." Qin Feng said.

Isn't it too wasteful to purchase a trainer of the same type as a fighter with a higher purchase price than a fighter jet, and as a result, it is only used to train pilots? Now the Su-27UB in the Air Force is like this, the Su-27 is a heavy air fighter, the two-seat type is also quite valuable, and the result is that the most valuable life is consumed in the training of pilots, which is definitely not worth it.

"yes, what do you think?" Yang Gong asked.

"Single-seat becomes two-seater, air combat performance will decline, but compared with the second-generation aircraft, there is still a great advantage, I think, it is the most suitable for ground attack, so it can be used as a trainer attack aircraft, not a simple trainer aircraft."

The Su-27UB, which is a simple training aircraft, is really a waste, and now, it can also be used as an attack aircraft.

"Of course, this kind of aircraft is different from our Flying Leopard, or even the Su-30, it does not need to be used as a special ground attack aircraft, the cost is too high, we are used to train pilots, and at the same time strengthen it in the fire control system, so that it has the ability to attack the ground, I believe, our technology has been able to do this."

What is the difference between air combat, and ground attack? In addition to carrying bombs, it is also necessary to support the fire control system, in terms of radar mode, air-to-air and air-to-ground are different, if you want to bomb the ground accurately, the terrain matching ability is very important, and the synthetic aperture function of the radar is a must.

When Qin Feng said this, she was looking at Qin Xue, after all, she was the R&D personnel of this airborne radar, and adding more functions was also the most familiar to them.

"That's fine." Qin Xue said: "Our technology is completely capable of doing it. ”

"Yes, the coach attack aircraft, many training aircraft, have also begun to have the ability to attack, even our instructor eight, can also throw bombs when needed, the trainer type of the J-10 should also develop in this direction, by the way, what else do you think?"

Qin Feng has flown a lot of planes, single-seater, two-seater, all flown over, is the performance of the two the same? Of course not, in addition to the reduction of the fuel tank, which leads to a shorter range, there are quite a few changes.

"If you want to be a two-seater, you have to add a second cockpit." Qin Feng said: "The cockpit is enlarged, in order to ensure the streamlining of the aircraft, so that the dorsal fin must be equally enlarged, so that the side area of the aircraft will be increased, which will affect the lateral quietness of the aircraft, and the rolling of the aircraft will be affected. Moreover, the rear compartment can't stand it either, and it's better to install a handle on the rear compartment. ”

When rotating, the closer to the center of rotation, the less centrifugal force is subjected, the rear seat pilot is farther away from the longitudinal axis of the aircraft than the front seat, the centrifugal force will be greater, when flying, the front is the student, the back is the instructor, so there may be problems, the student rolls, and the instructor is confused.

The previous plane was fine, because the roll rate of the second-generation aircraft of the J-7 was not fast, the pilot could stand it, and the J-10 was different, and when he flew alone, he might fly himself black, not to mention the two-seater rear cabin, if there is a handle under the rear seat, it can help the rear cabin pilot stabilize his body, so that when the front cabin suddenly rolls, the rear cabin pilot's head will hit the cockpit heavily.

Now, as Qin Feng spoke, he saw that Yang Gong had already begun to take out a small notebook to record, Qin Feng was stunned for a moment, this is a celebration meeting, not an analysis meeting.

Wait a minute!

"Do you want to be the chief master of two models at the same time?" Qin Feng asked.

Yang Gong is already the chief designer of Xiaolong, and now that he is like this, he must also engage in the two-seater type of Jianten.

Yang Gong nodded seriously: "That's right." What else do you have in mind? ”

Any other ideas? Qin Feng thought about it in his mind for a while, and said, "That bulging air inlet looks very sci-fi, can we make it?" ”

"Brother, don't ask the problem." Before Yang Gong could speak, Qin Xue spoke: "Let me give you a suggestion, if we want to attack the ground, it will require a lot of equipment, perhaps, we can learn the Western way and build a pod." It is a navigation pod and a target designation pod, and after hanging two pods, it becomes a ground attack aircraft. It's more appropriate that way. ”

Qin Xue analyzed it from the perspective of her own discipline, and when she said this, Yang Gong was also stunned.
