Because the progress of the core machine development project carried out in advance by the 624 Institute is very good, a lot of data does not need to be discussed too much between the two sides, even if Yang Hui is still a little dissatisfied with some of the technology of the core machine, but because the development of the core machine is a systematic project, many aspects are limited by the specific level of the country, Yang Hui can only make a compromise.

For Yang Hui's dissatisfaction, Chief Engineer Liu can only express regret: "Some aspects of the data are indeed not good-looking, but what we need is the overall performance of the entire core machine is enough, I can guarantee that the final data will meet the performance requirements, just in the name of my 624 director to guarantee, 90 years before the end of the qualified core machine, I don't need to go now." ”

Chief Engineer Liu is confident, Yang Hui is even more difficult to say anything, the 624 Institute is also the big brother in the field of core machine development in China, Southwest Science and Industry over the years because of the core machine project, the team that has been accumulated on the turbofan 10 engine has also been dismantled, and it can only be pressed down on the combustion chamber of the three parts of the core machine.

That is to say, if it is now up to the Southwest Science and Industry to do the core machine project in this push, it will not necessarily be as good as the 624 program, it should be the work done by the 624 people, and the Southwest Science and Industry will not be able to snatch it away.

"Then continue according to this plan, if we can come up with a mature core machine before 90 years, what else can we say about Southwest Science and Industry. Everything depends on the results. Anyway, the only requirement is that the surge margin of the core machine should be high. Our core aircraft this time is used to power civil aviation passenger aircraft, which is a major matter of human life. ”

The reason is that the surge margin of the core machine should be designed higher. This is all because according to the flight record of the regional airliner given by Embraer, the flight altitude of the regional airliner is not as high as that of the mainline airliner, and it is more susceptible to turbulence.

Not only does the ride feel less than that of a large aircraft, but also because the flight situation changes too much, the air intake of the engine will also have more changes, which requires the engine to have a higher surge margin, which is a point that Yang Hui must emphasize.

And Chief Engineer Liu seemed to be tired of listening at this time. simply told Yang Hui directly what the design of the core machine was based on this time, and it believed that as long as Yang Hui passed, he would not say anything.

"The core aircraft we developed this time is not only used for civil aviation, but also for military and civilian use, which can meet the requirements of military surge margin, and will civilian use be weak? I don't believe that the flight environment of civil airliners is as bad as that of military aircraft, so you can put your mind at ease. ”

After hearing that this core machine is dual-use, there is no need to worry about anything, but there is a trace of joy, and the small-thrust turbofan engine that can be used for both military and civilian purposes means that there is no need to worry about the military turbofan engine line in the future. Whether it's a large jet, a high-altitude long-endurance drone. Or maybe it will be an L-15 trainer in the future, and there will be no need to worry about the engine, which may be the first time in the republic that there will be a mature engine before the aircraft project is established.

"So we'll see, 50 million yuan plus 20 million dollars. We will also receive the special funds soon, anyway, money is not a problem, just ask for quality and efficiency. ”

For the development of the core machine this time. The scientific research cost requirements given by 624 are already quite inflated, according to the estimates of 624. Only 50 million yuan is needed to complete the development of the core machine, and the other 20 million US dollars is actually used by 624 to engage in other projects.

It's not that Yang Hui can't see this. The reason why I am willing to give 20 million US dollars is because this fund is a drop in the bucket compared with the 300 million US dollars extorted to Brazil by Southwest Science and Industry, and the 624 Institute is also more generous, and it is a dual-use core machine developed for military and civilian purposes, and after thinking about the request of 20 million US dollars, it was given to 624 institutes.

And Liu Gong is also full of joy, being able to get this extra 20 million US dollars is a good thing that the entire 624 can't think of, first of all, 20 million is not a small number, plus this is still in US dollars, this is amazing.

I remembered that when I was invited to visit the Central Aero Engine Research Institute of the Soviet Union not long ago, many of the equipment in the Soviet Union were things that were not available in 624 now, and I had no money in my pocket at that time, even if the Soviet Union agreed to export some special test equipment, Chief Engineer Liu still had no money to purchase these things, but now with this money

"Okay, well, we will complete this project with the greatest enthusiasm, and hope that the funds will arrive soon, and we are ready to use the funds to purchase some special equipment, which will be of great benefit to our next scientific research and testing work."

As long as he has the money in place, and the 624 Institute also guarantees to take out the things on time, Yang Hui will not care what the 624 uses the funds to procure.

Regarding the new core aircraft issue, the situation has been dealt with almost, and when I returned to the Southwest Science and Industry again, it was a full twenty days before Yang Hui left, and the J-18 radar selection that was about to be held before leaving had been completed, and the final result was a little unexpected, but I didn't do too much entanglement.

Anyway, the selection of this radar is actually not considered to be decided by the Southern Science and Technology Industry, this thing can actually be regarded as an important subsystem as the engine, the engine is selected by the army, this time the radar is naturally selected by the army, and the army's choice is to go directly to the radar with the best performance.

Different from the J-82 project in the previous plane, the J-82 project in this plane was given two years ahead of schedule because of Yang Hui's butterfly wings, and the current J-82 II aircraft has been finalized, and the procurement share of the first batch of a flight regiment was given to Fengtian by the Air Force.

After all, in this era, the J-82 is still the only twin-engine "long-legged" combat interceptor that the Republic can afford, and the radar used by the 82 project in this plane has also changed greatly, although the APG-65 radar from the F-18 has been castrated by the US Navy to attack the sea, but the overall performance is still quite good.

Naturally, the army chose the APG-65 radar of the old United States, and the localization task was handed over to the Jinling 14 Institute, which made the Southwest Science and Industry not dissatisfied, anyway, the ability of the 14 Institute is still quite good. There are not too many regrets that the project did not fall to the 38 institutes under the Southwest Science and Industry Group, anyway, these 38 institutes are also preparing to focus on early warning aircraft.

Changhong Factory, which has always had a good relationship with Southwest Science and Industry, unexpectedly took out the JL7807 radar for the No. 10 project, and added additional ground and sea attack functions to this radar, although it is heavier than the 7807 radar in terms of weight, but it is not a matter of J-18, and overall this is also a very good radar candidate model.

But the Changhong factory is now a little too much radar project in hand, considering the limited scientific research strength of the Changhong factory, the army finally chose the 14 copycat APG-65 radar, although there are some other reasons in it, but it doesn't matter, anyway, the probability of successful development of these two radars is quite large, or consider the performance.

Yang Hui didn't pay much attention to the problem of radar, but he was very interested in the 29 institutes that were just about to pack up the materials and leave, and the 29 institutes came to the southwest science and industry to participate in the bidding, which is quite interesting in itself, as if the 29 institutes paid more attention to electronic countermeasures, although they also had research on radar, but they came to compete for the J-18 airborne radar project and did not go to the right mountain pass at all.

You are a professional giant engaged in electronic countermeasures in China, and it must still be engaged in electronic countermeasures to have a future, and it is also the most promising project, you don't see how brave the US imperialist EA-18G Growler electronic warfare aircraft is, and even be able to pick up the F-22 head-on, relying on its powerful electronic countermeasure capabilities, if the J-18 can also have this function, then it is definitely like a tiger with wings.
