"Seeing this, I really want to come here for a test flight." Qin Feng tried to take his eyes off the cockpit, he didn't even dare to sit in, if he sat in, he definitely didn't want to leave, after all, for him, the current cockpit was too attractive.

For pilots, the cockpit is a platform for them to communicate with the aircraft, they sit here, control the aircraft, look at all kinds of data, a good cockpit allows pilots to take care of the aircraft with less energy, and put more energy into observing the surrounding environment.

The more graphical the display, the simpler it is, and even through the transfer, only the important information is displayed on it, for example, the head-up display is like this, when flying, the flight data is displayed, and when the combat is fighting, the fire control data is displayed, so that the best effect can be played.

Therefore, the glass cockpit is bound to be the trend in the future, and on the J-10 fighter, it is planned to use this method, however, the J-10 has only now reached the point of building a metal prototype, and there is still a long way to go before the assembly of the actual machine.

"What about activation? What type of engine is used in this aircraft? Qin Feng tried his best to divert his gaze from the cockpit, he couldn't look at the cockpit, just looked at the engine in the tail.

In China, the engine is the biggest weakness, even more than avionics, don't look at the modern avionics technology is very complicated, but in the diligent work of domestic scientific researchers, the gap in avionics is gradually narrowing, but the engine is different, in the field of engines, almost has always been standing still, in the turbofan engine, even more so, it is said that the localization of Spey engine, has stopped, the country after spending a huge amount of money, this project is ultimately a dead end, heartache.

The engine used in the trainer aircraft is different from that of the fighter, it does not need to have much thrust, and it does not need to have an afterburner, but it needs to be stable and reliable, especially the fuel consumption rate is low, after all, the trainer aircraft needs to train pilots, and during the entire life cycle, the flight time is very long and the fuel consumption rate is low, which is a very important advantage, which can significantly save costs.

"In terms of engine, we use the TFE-731-2A turbofan engine produced by Garrett Company in the United States, which was selected by Lao Ba." Shi Lao said.

Speaking of engines, it is still the weakest link in the country, although the country has been sanctioned by the United States, and all kinds of military exchanges have been suspended, but now this project has not been affected, this is because the export object of this aircraft is Lao Ba, and the Americans sanction China, not Lao Ba.

This is the same as the Super Seven Project, the J-8 Peace Model Project was suspended all of a sudden, and even now those planes and equipment are still detained by the Americans, but the Super Seven Project has been greatly eased, and even Grumman Company gave a notice in advance, so that Tu Lao's subordinates can bring back the information as much as possible, this is because the Super Seven Project is originally an international cooperation.

The same is true of the K-8, this aircraft is to be exported to the old bus and installed with American engines, and there is no problem at all.

This engine is advanced in performance and is also the engine of the United States' own domestic trainer aircraft.

As a small thrust turbofan engine, its maximum thrust is only 16 kN, and the Su-27 engine, a single maximum thrust of 122 kN, you know how big the gap is, and the fuel consumption rate of this engine is 0.502 kg / (kg force · hour), this has nothing to do with the size of the thrust, it is the average fuel consumption rate of one hour per kg force, and then look at the third aunt, this indicator is 2.0, and the third aunt is four times it! It can be seen how advanced the aviation technology of the United States is, and this is still the comparison of turbofan engines, and if compared with turbojet engines, this gap can even be expanded to ten times.

It is precisely because of this advanced engine that the K-8 has a large range, quite an excellent cost-effectiveness ratio, and at the same time, as a mature engine, its periodic inspection interval is as high as 1,000 hours! During the entire life of the aircraft, there is no need to change the engine at all.

"Moreover, its engine is still digitally adjusted." Shi Lao said: "If our plane is going to be digitally telex, the engine can support it." ”

Shi Lao mentioned the digital telex for the first time, and when she said these words, Gu Tingting listened carefully on the side, after all, this is the purpose of her coming here to investigate.

"It's a pity." When he said this, General Lin suddenly sighed.

What a pity? Such a good engine, you can't use it! General Lin felt a pity for this, of course, this is also something that cannot be helped.

This kind of training aircraft is not only to meet foreign trade, but also for its own use, and if it is used for its own use, the American engine will never be provided, so if the country wants to use this kind of aircraft by itself, there is still a gap in the engine.

"General Lin, this is also where I want to report to my superiors." Shi Lao said: "We are now communicating with the Soviet Union and carrying out military-technical cooperation, and the Soviet Union also has engines of the same specification in China, although we cannot get advanced engines from the United States for our own use, but in the Soviet Union, we still have a chance." ”

As soon as Shi Lao said this, General Lin's eyes lit up, yes, why didn't I think of it?

The door to the West has been closed, and it is not possible to buy advanced equipment from the West, but what the West has, the Soviet Union still has, such as fighter jets, after ten years of choice, is now finally going to the step of purchasing, and if it succeeds in fighter jets, it can also cooperate in other aspects.

The USSR also had a large number of trainer aircraft, what kind of engine did they use for their trainer aircraft? As long as the specifications are about the same, you can use it, even if the Soviets' engines are slightly behind, the fuel consumption is higher, and the life is shorter, these are secondary, and now the problem of whether there is or not will be solved.

In terms of domestic research and development, General Lin did not hold out this hope, and it is difficult for the Air Force to concentrate all the forces in China to build a turbofan ten, and the number of equipment for this kind of training aircraft will not be much, and it is not the most urgent, so it is impossible to guarantee it in terms of funds and personnel, so it is better to try to introduce it from the Soviet Union.

"It seems that if we go to the Soviet Union next time, we can bring our comrades from the 320 factory with us." General Lin said: "However, looking at your appearance, I guess I already have an idea, right?" ”
