Zhao Shouhong's words are very skillful, neither denying nor acknowledging, and at the same time aroused Qian Xuesen's enthusiasm for work. At the same time, he said that there were no astronauts, and it seemed that another team had not developed manned space technology, so he should not be discouraged.

Qian Xuesen's eyes emitted a scorching light. It was obvious that he had been aroused by Zhao Shouhong's determination to compete. He believed that he would work harder in the future.

Zhao Shouhong turned his head to look at the group of scientists and said, "I remember that the scientific research in aerospace is put together. Why do we only see a group of rocket experts, but no jet engine experts?"

"Oh, today happened to be the first jet fighter flight, so they were all at the aircraft test site. It was more than 100 kilometers away, so it was not very convenient for them to come here." Qian Xuesen replied on the side.

"Is that right? You have to go and see. You guys keep busy. I'll go to the test flight." Zhao Shouhong waved his hand and gathered the members with surprise on his face. Zhao Shouhong left immediately, and the scientists did not have so much etiquette. After Zhao Shouhong left, they immediately devoted themselves to the new scientific research work.

Zhao Shouhong and his group drove to the test flight site, which was already half a day later. When Zhao Shouhong arrived at the airport, the test flight was over, and the silver-gray jet was landing on the runway.

Zhou Peiyuan, the team leader in charge of this aircraft design, walked over quickly, "Why are you here?"

Zhao Shouhong said with a smile: "You do such a big thing, I will naturally come and see it." As he spoke, he pointed to the jet fighter that had just stopped.

Zhou Peiyuan said embarrassedly: "You are so praising me. What a big deal? It's just a test flight of the plane. Nowadays, major design bureaus and aircraft factories in China have no test flights that month."

"But this is different." Zhao Shouhong said meaningfully: "This is a jet aircraft. In the future, it will replace propeller aircraft and occupy the dominance of the sky for a long time." These words seemed to be talking to himself. He turned his head and said, "Tell me how the performance of this new aircraft is?"

Zhou Peiyuan's face suddenly looked a little ugly when he heard this request. Looking at Zhao Shouhong's earnest gaze, he reluctantly said: "The jet aircraft is still in its infancy and everything is very immature. The two Xinhua 1 ramjet engines used in our new aircraft are only about 800 horsepower. Fortunately, the jet aircraft has smaller wind resistance and can reach a maximum flat flight speed of 870 kilometers per hour. Of course, this is just laboratory data. Because today is the first flight, we have not conducted extreme tests on the aircraft. However, when we flew multiple prototypes, we found a big problem. Because the jet aircraft's output is large, the fuselage structure is unbearable. We have had two accidents of air disintegration and lost a test pilot."

"Take me to see the plane." Zhao Shouhong didn't say anything, but walked towards the plane under the leadership of Zhou Peiyuan. The only jet fighter in the world was soon presented to everyone. Zhao Shouhong walked around the plane for a few times. He found that the plane had a triangular nose, a pair of straight down a single wing that was not much different from the propeller plane, and two huge jet engines were attached. In addition, four cannons were installed below the nose.

Zhao Shouhong looked at it and nodded, "Your aircraft has many problems. First of all, the installation method of the landing gear is wrong. Today's jet engines are more efficient and have very high thrust. It is completely different from the working mode of propeller aircraft. When the rear three-point landing gear landing in the past, the engine nozzle is obliquely lower, and accidents are likely to occur due to reaction forces, so it must be changed to the first three-point landing gear."

"I understand." Zhou Peiyuan's eyes lit up when he heard this. He immediately took out his notebook and started to remember it bit by bit.

"The wings of the aircraft are too thin, which will lose lift and reduce the structure of the fuselage. In addition, the wind resistance of the flat wing is too large, so it is no longer suitable for high-speed flights." Zhao Shouhong pointed to the wings of the aircraft and said: "The power of the aircraft has been greatly enhanced today. There is no need to increase the additional lift through the wind resistance of the flat wing. We need to minimize the drag and make the aircraft faster." Zhao Shouhong said.

"What are some good suggestions do you have?" Zhou Peiyuan asked.

Zhao Shouhong said: "To change the wing from a straight wing to a swept type, if the sweep angle of the wing is increased to forty-five degrees or even sixty degrees, the drag can be greatly reduced."

As an expert in fluid mechanics, Zhou Peiyuan knew the benefits of this method by entering his ears. He nodded and said: "Sweeping the wings in this way can indeed reduce the drag of the aircraft, but according to the laws of fluid mechanics, the airflow will flow from the wing root to the wing tip, and lose a lot of lift in vain."

"This problem is not easy to solve at the moment, but you can add wing knives to the wing surface to prevent the loss of lift." Zhao Shouhong gestured: "There is also the problem of flutter. The faster the aircraft is, the stronger the flutter of the wings will be. In the era of jets, this flutter has become a big problem. At the very least, the wing breaks, and at the worst, it will disintegrate directly in the air. I think the first two accidents came from this."

Zhou Peiyuan was quite convinced that Zhao Shouhong could guess the situation without asking the reason. At this time, he no longer regarded Zhao Shouhong as a leader who came to inspect the work, but unconsciously regarded him as a colleague and humbly asked for advice.

Zhao Shouhong said: "If the thickness of the front end of the wing is increased to two to three times, the center of gravity of the wing can be moved forward and the moment of inertia can be reduced, so that the flutter can be eliminated."

"It's indeed a good idea." Zhou Peiyuan couldn't help but slap the table. He asked immediately, "What other good idea? Let's talk about it?" Zhou Peiyuan excitedly forgot about each other's identities. He actually pulled Zhao Shouhong to sit on the ground and said, while using branches to gesture to assist instructions on the ground. Looking at the postures of the two, many guards couldn't help but sweat coldly.

Even if Zhao Shouhong no longer serves as president, he is also one of the important leaders of the country. With his identity as the founding father of the nation, he is probably not even as noble as him. Zhou Peiyuan actually pulled the father of the nation to the ground, which was simply a rebellious thing. However, Zhao Shouhong was not at all unusual, and they pretended to be unable to see it tactfully.
