Wang Xushan smiled happily after hearing this, "I'm so excited, so excited!"

Little did he know that the aircraft Yang Xiaotao wanted to build was the Alliance MiG-25 as a reference, and the main purpose of developing the MiG-25 was to deal with the XB-70 bombers and Blackbirds of the United States.

So from this aspect, Yang Xiaotao's talk about developing fighter jets can be regarded as being of the same line.

"But we found that the two vertical tails at the back are a bit interesting!"

Wang Xushan spoke again, and then looked at Yang Xiaotao, because when he was at the train station, he found that Yang Xiaotao valued the design of the vertical tail very much.

"Do you have any ideas?"

Yang Xiaotao asked, and Wang Xushan nodded immediately, "We discussed it, and Lao Sun told Lao Zhou that the function of the vertical tail is to maintain the balance of the aircraft during flight!"

"It's just that foreign countries used to use single wings, but these double wings are rare."

"We guess that the design of this double vertical tail should also be based on this aspect!"

After Wang Xushan finished speaking, Wu Zhe interrupted and said, "I also looked through the alliance's aircraft over the years and found that this double vertical tail design does exist."

"It seems like both the Alliance and the United States are doing research and development. I don't think their efforts are in vain. Maybe this is the direction of future development."

Yang Xiaotao nodded, and then opened the information in front of him, "This is based on some materials provided by the battlefield in Shanghai!"

As he spoke, he gave it to Li Haonan beside him and circulated it.

"It clearly states that this big guy's speed has reached Mach 3!"

"If they hadn't tried to turn around and escape, we might not have been able to hit them!"

"Since the other party uses this method of double vertical tails, it shows that it is necessary!"

"The next design of our aircraft will be based on this!"

Yang Xiaotao spoke directly about his decision.

Everyone looked at each other and no one dared to object.

Here, the only person who has the qualifications to be a communicator is Yang Xiaotao!

"Understood, we will arrange for someone to design it immediately!"

Wang Xushan nodded immediately, without any doubt about Yang Xiaotao's words.

"Also, now that it has been restored, the relevant design, layout, and angles must be carefully confirmed. This is very important to us!"

Yang Xiaotao thought that when it comes to high-speed flight, aerodynamic requirements will be more stringent.

Wang Xushan naturally knew this. He was studying aerodynamics, but it didn't involve such a fast speed. He immediately nodded in agreement.

"Mr. Yang, I have a question!"

"you say!"

Li Haonan handed the information to Wu Zhe, and then said, "I wonder if you have heard of a word, thermal barrier."

"Thermal barrier?"

Wu Zhe's eyes widened immediately, and then he nodded, "I've heard of this."

Yang Xiaotao vaguely felt that he had heard this word somewhere, but he was not sure, and then he looked at Li Haonan.

Since he brought it up, he naturally explained it.

Seeing that Wu Zhe had no intention of explaining, Li Haonan said, "What I call thermal barrier is that when an aircraft flies at supersonic speed in the atmosphere, the body of the aircraft will interact with the air, and high-temperature compressed gas will be formed on the surface of the aircraft.

heating..."

"So, the temperature that affects the surface of the body is the thermal barrier."

"Generally speaking, the speed of ordinary aircraft will not exceed Mach 2, but if our aircraft exceeds Mach 2.5 or even Mach 3, it will definitely face the problem of thermal barrier."

"I have seen in the data that if it exceeds Mach 3, the temperature on the surface of the aircraft will rise to about 350°C."

"This temperature has exceeded the ultimate temperature of aluminum alloy."

"So, if we want to overcome this thermal barrier, we have to use better high-temperature resistant materials."

"For example, the titanium-rhenium alloy used in our engine, or a slightly worse titanium alloy."
