The nose of the MiG-21MF fighter is raised upward, the landing gear is lowered, the wheels are firmly in contact with the runway, and then slides forward.

Qin Feng's landing is quite standard, and in the eyes of the Egyptian Air Force, it is definitely one hundred points.

When the cockpit canopy was opened, the first thing Qin Feng did was to take off this helmet, but when he saw the ground crew surrounding outside, he quickly put down the glass piece in front of his helmet again, covering his face tightly.

"Alexander, you're amazing!" The people below shouted, watching Qin Feng walk down the gangway, and the group of people actually lifted Qin Feng up and threw him high into the air.

Qin Feng was wearing Alexander's flight suit, this plane was also Alexander's, the ground crew was familiar with it, thinking that it was the Alexander who usually didn't smile, the whole airport was boiling, and the MiG-21 piloted by Alexander drove away the Jewish reconnaissance plane!

Qin Feng fell from the sky, and then was thrown up again, three times in a row, and finally, Mustafa's plane landed, and as soon as his plane stopped, he poked his head out, and shouted to this side: "You lambs, don't you go to work?" ”

Mustafa's face was very serious, as if he was dissatisfied because he had not completed the task, and the ground crew saw him like this, and quickly dispersed.

Mustafa took Qin Feng and went to change his clothes, shook off everyone, and then said with a smile: "Qin, your actions are really amazing!" However, it was Alexander who had just ascended to the sky. ”

Mustafa's meaning was very clear, and of course Qin Feng knew it, and said, "That's right, that Alexander's technique is amazing. ”

Han Guo's air base in Egypt is top secret, and it is already a preferential treatment to allow the other party to test fly the MiG-21MF once, and if he also participates in the interception mission, maybe he will leak secrets, even Mustafa feels that he is a little bold this time.

Taking off his flight suit, Qin Feng came to the experts again.

"You're so daring." Regiment Commander Tang said to Qin Feng: "I have repeatedly emphasized the discipline of secrecy, and you actually took the initiative to provoke the reconnaissance plane." ”

"Don't take it as an example." Qin Feng hurriedly said.

"And next time?" Commander Tang said: "Until we leave, you don't want to fly anymore." ”

Captain Tang walked away with a straight face, and Song Lao slowly walked to Qin Feng's side and said, "That plane, how is it flying?" ”

Compared with Commander Tang, Song Lao attaches more importance to flight quality, because the purpose of this visit is to transport away the MiG-23 and MiG-21, and this kind of MiG-21, which is imitated after being brought back by his own side, is the J-7III, which belongs to the main project of Chengfei in the future.

Qin Feng is not a violation of discipline, after all, under the circumstances at that time, it was right to give a helping hand to the class brothers, and besides, Qin Feng could be regarded as winning glory for everyone in front of the class brothers.

Hearing Song Lao's question, Qin Feng carefully recalled the control in the sky, and said: "I feel that its flight quality is not as good as our current J-7, and its flexibility is not good." ”

Song Lao frowned, in order to deliberately make a large air intake cone to facilitate the placement of radar, and in order to increase fuel, he made a fuel tank on the back of the aircraft, which seems to have an impact on aerodynamics.

It depends on whether the price is worth it.

Glancing at the MiG-21MF again, Song Lao said: "Let's go, let's complete the acceptance of the MiG-23 first, you and I will go over, and let's collect the information." ”

Mr. Gu and some others were carefully carrying out the technical acceptance of the aircraft, while Song Lao took Qin Feng and began to sort out the corresponding technical information on the side.

Several large wooden boxes, opened in turn, according to the catalog, a book of technical information, was carefully read by Song Lao, any omission of information, there may be a big problem in the imitation.

Qin Feng assisted Song Lao, checked the information together, looked at it, and suddenly said to Song Lao: "This kind of variable sweep wing aircraft, the hinge is made of steel, I'm afraid it will cause the weight of the aircraft to be too large, right?" ”

When Qin Feng was helping to check the information, he happened to turn here, looked at the contents inside, and couldn't help but say.

"Yes, if it is made of titanium alloy, it will be better, but unfortunately, the processing and welding of titanium alloy are all difficult problems." Song Lao said to Qin Feng while tidying up.

The variable sweep wing is an idealized scheme to achieve the best aerodynamic layout at different speeds through the different sweep angles of the fighter.

But at the same time, it also brings an increase in the weight of the structure, depending on how the aircraft designer chooses.

"Young man, you don't understand this, variable sweep wing, but the trend in our current aircraft design industry, the added weight for this, is worth it." At this moment, Lu Lao, who was in charge of testing the variable swept wing of the aircraft, heard Qin Feng say about this problem with the variable swept wing, and immediately spoke.

On the land, Qin Feng has already met, this Lu Lao is from Nanchang, and at the same time, I heard that Nanchang proposed a variable sweep wing attack aircraft, as a replacement for the strong five, it seems that Lu Lao is very fond of the variable sweep wing.

"Well, yes, Lu Lao, you're right." Qin Feng said, of course he can't argue with Lu Lao about the design of the aircraft, after all, he is a designer, he is just a pilot, and the aircraft designed by the designer can fly by himself.

"Especially for ground attack, as soon as the wings are so deployed, the ultra-low-altitude flight ability must be good, and now, with the development of missiles and radars, high-altitude penetration is unreliable, and ultra-low-altitude penetration is the right way." Lu Lao said while he was busy.

By reversing the structure of this MiG-23, the republic's own attack aircraft with a variable swept wing was developed! Lu Lao is full of confidence, although he is full of gray hair, he is full of energy.

On this day, he worked until the evening, when Regiment Commander Tang received a telegram, and his face changed again: "Comrades, in order to keep it secret and complete the task as soon as possible, we originally expected that the seven-day testing work should be completed within four days!" Let's work hard, tonight, let's do a little more. ”

These two planes, which were secretly sold to themselves by the Egyptian brothers, if something goes wrong in the past few days and the Soviets know, these planes will not be bought.

After that, Head Tang said to Qin Feng again: "Qin Feng, you go to the Consulate General in Alexandria to coordinate and secure the cargo ship that transports these two planes, there must be no accidents." ”

Qin Feng can't fly, it's useless to stay here, it's better to send it to coordinate.
