"Okay, talk quickly, I like it."

"I respect you."

As he spoke, Mr. Song went to get the wine glass, but the goblet was already empty, so he picked up a glass of white wine and stood up.

Yang Xiaotao didn't take it seriously. He was also holding a drink and looked at the old man who was half a head taller than him. He had a righteous look on his face and couldn't help but feel good about him. "Uncle, I'll do it first out of respect."

"Okay, I'll accompany you."

Gudong

The two of them finished the wine in the goblet, and at this moment, the people around them stared at Mr. Song who stood up and was about to sit down.

Mr. Wang's Adam's apple clacked even more.

Mr. Chen also looked at the two of them speechlessly.

Mr. Xia felt regretful in his heart, regretting that he had not made it clear to Yang Xiaotao earlier.

belch

As soon as Yang Xiaotao sat down, he heard Mr. Song burping, and his face instantly turned red. Then he smiled at Yang Xiaotao, "I, I forgot, you can't drink too much."

Burp~

"Quickly, send Lao Song back quickly."

Mr. Chen quickly said, this is Lao Mo. If it is demolished, no one will be able to bear the responsibility.

Mr. Wang stretched out his hand to pull, ready to leave, but Mr. Song's body just shook, and Mr. Wang almost bumped into Mr. Qin.

Mr. Xia quickly said something to Yang Xiaotao from the side.

Yang Xiaotao was also stunned, but he reacted quickly, got up and ran to the opposite side, and grabbed Mr. Song when he was about to throw away his hand.

Then I felt that Mr. Song had great power.

He has met many people over the years, and the one with the greatest power is probably Zhou Kui.

But here, he felt that even the three Zhou Kui might not be able to catch up with him.

Fortunately, Yang Xiaotao is not an ordinary person.

The strength is also surprisingly great.

Just when Mr. Song felt someone grabbing his arm, he subconsciously pulled hard, but Yang Xiaotao's grip was so tight that he couldn't pull it at all.

Mr. Song got drunk and tried his best again, but he still couldn't break free.

This time, Yang Xiaotao used both hands and one arm, and then used force to pull Mr. Song up.

"Uncle, we've finished eating and it's time to go home."

"When the time comes, we'll make the machine tool, and you can come and do it..."

Yang Xiaotao persuaded and supported her, and the two quickly walked out of the restaurant.

Yang Youning, Liu Huaimin and others followed behind, fearing that something would happen.

The people at the Chinese Academy of Sciences also knew what their boss was capable of, but when they saw that he was so obedient, their eyes widened and they hurriedly ran out after him.

Mr. Wang rubbed his shoulders, and Mr. Qin opened his mouth.

Finally, the two looked at each other and nodded to each other.

"These damn monsters are all monsters."

...

the next day.

After Yang Xiaotao arranged the work in the machinery factory, he drove to the Seventh Machinery Department.

There were too many things going on yesterday and I didn't say a few words to Mr. Qian. He could also tell that Mr. Qian had something to say.

So after making arrangements, I drove over.

When he came to the office, Mr. Qian saw that it was Yang Xiaotao, so he called him directly and started talking without hesitation.

"Xiao Tao, come on, sit down."

"Uncle, I don't think I had time to talk yesterday, so I came to take a look."

Mr. Qian nodded, "If you don't come, I will call you and tell you. It would be better if you come."

"I read the notebook. I have studied the situation he mentioned before. But this is the first time I have studied this kind of aircraft."

"However, the basic principles are correct."

Mr. Qian was not polite when he came up. He took out a pen and paper to write and draw on it. After this period of study, Yang Xiaoao could basically understand it.

"You see, this is that kind of effect. It can appear on objects moving at high speed, and the compressed lift formed can form a sound barrier shock wave. When I studied it earlier, I called it a waverider."

"I just didn't expect that this kind of phenomenon could occur on this aircraft."

"By the way, what happened to Shengjing last time was because of the design imbalance at high speed. I guess it is also related to this."

"So, when you are designing an airplane, you must consider the problem of compressed air at high speed. If used well, it can become a free lift. Just like this person said, when the airplane is in stance,

The generated shock wave is used to form upward compressed air, which is then captured by the wings and turned into free power."

"This is very important, especially if you want to build a high-speed, high-altitude fighter jet."

"By the way, this is a design of wing angle that I studied."

"The normal sweep angle is usually between 20 degrees and 60 degrees, depending on the design goals and performance requirements of the aircraft. If you are pursuing high speed, I think it should be between 40 degrees and 45 degrees.

.”

Qian Lao talked little by little. Ever since Yang Xiaotao came in, he has not been idle for a moment.

After talking about the wing sweep angle, let’s talk about the placement of the engine.

Yang Xiaotao's decision was to place it on the sides of the aircraft fuselage instead of at the rear.

This is also based on the design of the MiG-25.

Mr. Qian had a very pleased look on his face, "Yes, I think so too."

"This is good..."

"Also, uncle, I think if the aircraft is flying at high speed, it is best to use the dihedral angle of the wings, but I am not sure about this angle."
