Although Chief Engineer Yu had already said that Yang Hui should be bold to say, as soon as Yang Hui said this, the other personnel had different opinions, and an engineer next to him who was debugging the tail of the aircraft stopped working, and he was very annoyed by Yang Hui's opinion.

"What do you mean by this, this was originally an aircraft designed for trainers, and you say it is not qualified as a trainer aircraft? I'm here to see what you have to say. As he spoke, he put down the tools in his hand and walked over, and it seemed that he would not stop without giving a convincing reason.

Chief Master Yu didn't have any expression, just looked at Yang Hui quietly, waiting for his answer, if Yang Hui couldn't say anything, I'm afraid that Chief Master Yu would be the first to criticize him.

No matter what others think, since he said it, Yang Hui naturally has his reasons. So he continued, "The reason why I say that this aircraft is not suitable for a training aircraft is from my point of view. ”

Walked quickly to the front edge of the wing of the aircraft, pointed to the wing of the aircraft and said, "The first point is this wing, the J-7 is developed from the J-7, the delta wing is suitable for high-altitude and high-speed flight, but it is not suitable for training aircraft, of course, if you only plan to train the pilots of the second-generation aircraft, it is still barely a problem." ”

Seeing that the engineer who asked the question just now was also thinking about Yang Hui's question, Yang Hui paused. Wait until he figured it out and looked at Yang Hui again.

Yang Hui continued, "At present, some of the third-generation fighters in the world have begun to enter service, and the third-generation fighters highlight the ability of low-altitude subsonic combat. ”

In a word, Yang Hui pointed out one of the biggest problems of Jianjiao VII, that the aircraft can only train second-generation fighter pilots, and it will be blind in the era of third-generation aircraft.

At this time, Chief Engineer Yu and a group of R&D personnel all looked at each other, they didn't expect that the aircraft they had worked so hard to develop would fall behind before it came out, and the frustrated expression on their faces was obvious.

Director Bai next to him didn't expect that he was just talking casually, wanting to see how this unprofessional college student was learning in the formal course, but he didn't expect to directly point out such a big problem. Suddenly I thought about it, this is really a treasure, talent! I was really excited,

Chief Master Yu finally reacted, "What you said makes sense, let's continue to talk about everything else." "A ruthless commander-in-chief decided to continue to accept the blow.

"Okay, then I'll continue to say that the Jianjiao-7 is actually a two-seat training aircraft, with less internal fuel and a short flight range that has little impact, but there is still a fatal problem."

As soon as these words came out, everyone else was going to cry. I worked hard to develop an airplane, and I was seen to have a big problem at a glance, and I immediately pointed out a fatal problem before I finished it.

"As a training aircraft, the most important thing is the trainer function, but the Jianjiao VII is not very good, the rear trainer's cockpit vision is narrow enough, and the cockpit vision is low, and the front is blocked by the front seat pilot, I'm afraid it doesn't have much effect even if you add a periscope."

Although this problem is scary at the beginning, the R&D personnel know it early on and can accept it, so it is not as big as the above one. However, the two problems were said together, and the blow to the personnel of the first was big enough.

Chief Master Yu was the first to take the lead in clapping, which was a little confusing. What are you clapping with when you're like this, isn't it too much of a blow......

"It's very good, it's really someone who even Lao Wu is optimistic about. The questions you mentioned are important and to the point. But now we can't modify it, the above is in a hurry to get the plane, and the pilots of these planes have not been systematically trained, so it is urgently needed! ”

Chief Engineer Yu suddenly pointed to the biggest key problem of improvement, and there was no time. "There is no time for this aircraft to be improved, and if you want to improve it, you have to make a major change to the aerodynamic layout of the aircraft. We have not conducted pre-studies and have no experience in wind tunnels. It's going to take a few years, and that's the key. ”

There was silence all around, probably because after listening to this question, it was very clear that it was difficult to improve. This plane is backward from birth, but it has to be hard-headed, so that many scientific researchers are not in the mood to continue.

A few bombs were dropped, and sure enough, the morale was low, Yang Hui felt that he had lowered the morale, and now he needed to mention the morale to everyone.

"In fact, I had some research on the aerodynamic layout of this aircraft when I was in college, mainly to improve the performance of subsonic combat at medium and low altitudes. If you want to follow my pneumatic plan, if you go to the blowing tunnel and have a specific plan, it will definitely be much faster, at most only half a year. ”

Yang Hui didn't know if he should say his plan, and it was actually impossible to adopt it, and his plan had changed a lot. The money spent is not the little money allocated to the Seven Sects of Annihilation now.

Obviously, the chief engineer also knows this, and there is no possibility of implementing it, and in the end it just makes everyone's mood fluctuate a little more, but it is impossible for an aircraft designer to resist the temptation of excellent aerodynamic design.

"Then you can talk about your plan, I'm afraid it's impossible to change too much."

Yang Hui's thoughts flew to the type of plane two thousand years later. It is also a product of the 0011 base, and it is also a descendant of the magic transformation of the J-7, but it can meet the requirements of a new generation of training aircraft, and the most important thing is that the aircraft can be built under domestic conditions now.

Walked to Yang Yue's side and asked for the notepad in Yang Yue's hand, and now start drawing there.

"That's it, let's see!" Yang Hui handed over the three views of the plane and the axis side map to Chief Master Yu, and he didn't want to say anything more, and he didn't need to say anything more, everything was on that map.

Seeing that the chief master Tu Yu had no expression at first, sometimes frowning, sometimes closing his eyes and pondering, and finally a sudden realization after understanding the problem. Finally, it turned into a wry smile.

"The aerodynamic layout of the aircraft is indeed very good, and now the domestic technical conditions can also be realized, but the changes are too big, and now there are so many models off the horse, and it is difficult to re-launch a model of aircraft!" A face of unwillingness and helplessness, and perhaps some expectations.

Can it not be good? Twenty years later, the low-cost training aircraft will be better than the current Jianjiao-7, I don't know how many grades. It is no exaggeration to say that with this aerodynamic layout, the rear seat trainer cabin is canceled, and the back of the plane is pressed down a little more, and the fighting can completely blow up the J-7, and the internal oil can also throw the J-7 far away.

Hearing Chief Yu's evaluation, coupled with Chief Yu's expression, I also guessed that the pneumatic layout on this piece of paper must be excellent. Someone is ready to come and ask for a sketch, wanting to see what it looks like, after all, the Annihilation Sect Seven has been criticized as useless, and no one is interested in the Annihilation Sect Seven.

Chief Master Yu, who didn't think about it, held the drawings tightly, and then, to everyone's surprise, tore the drawings into pieces twice.

The change was so sudden that no one could react. What the hell is going on?

"Old Yu, what are you doing here?" Director Bai didn't understand the reason, and immediately reminded him.

There was a long sigh, and then Chief Master Yu looked at everyone's puzzled and suspicious eyes.

"This thing is no good now, for the time being, we can't do it without money, let's continue to get the Seven of the Annihilation Sect out! Although it will lag behind, but now the J-8 and J-7 are still continuing to develop? It's still useful."

Speaking of which, Chief Master Yu himself actually didn't want to believe his own words. After all, we all know about the problem with this plane now. Is there really a future in the future?

Then Chief Master Yu set his eyes on Yang Hui again, and his gaze was similar to that of Wu Lao a month ago. Maybe I also see hope!

"Yang Hui, right? I hope you don't mind if I tear this piece of paper, it really can't show up yet. I'm afraid it will disturb the hearts of the people in the school. After reading that piece of paper, I always felt that this plane needed to be changed, in fact, we couldn't change it anywhere, and even I am a little confused now. ”

I didn't expect a drawing to have such great power, even the old designer in his fifties was confused, and Yang Hui suddenly regretted it.

"It's nothing, it's just a simple picture, it's all in my head, it seems that I'm too radical and almost disrupt the order of scientific research."

"You can rest assured that the plane on this drawing will definitely soar into the sky." Chief Master Yu looked at the shredded piece of paper in his hand, and there were tears in his eyes.

Seeing this, Director Bai felt that it was time to leave and couldn't stay any longer. "Old Yu, let's go first, there are still dozens of kilometers to go."

"Okay, it's not good to keep you for another drink today." Hearing that he was leaving, Chief Master Yu had nothing to keep, so he just turned his head and said to Director Bai

"Yang Hui, your aerodynamic skills are very good, if it weren't for the fact that we didn't have the ability, I would definitely keep you. But now that one of us is like this, you just added to the regret when you came, and I believe you can make a difference in the second one. After speaking, he grabbed the piece of paper in his hand tightly and walked away.
