When Zhou Hai heard this, he was slightly puzzled, and said, "Go, why don't you go?" ”

Astronauts, the super-elite at the top of the human pyramid, are magical, and their number is almost the same as that of cutting-edge scientists in the history of human civilization.

Compared to becoming a top pilot flying the J-20, becoming an astronaut stepping on the stars is more attractive.

"Registration may not necessarily become a preparation, the preparation must be through centralized selection, and after the selection, it must be determined, and the selected astronaut may not be able to go to space."

Su Peng stared at the edge of the blue sky in the distance and expressed his inner concerns: "What is the difference between an astronaut who can't go to the sky and a salted fish?" ”

Whether or not an astronaut can go to space is the basis for measuring value.

From registration to the selection of official astronauts, there are many hurdles to go through, which is almost the same as the pilot recruitment mode, but the selection personnel are the best Air Force fighter pilots, not ordinary people.

The best of the best are selected, and the selection conditions are so harsh that it makes people's scalp tingle!

At the beginning, the criteria for the selection of the first batch of astronauts were all active special pilots of the Air Force, active top test pilots, and even so, only 14 astronauts were selected from the 1,500 Air Force pilots.

1500:14, a cold and cruel number.

Among the first batch of official astronauts, only three of them took the first step to conquer the starry sky, taking the Shenzhou spacecraft into the mysterious and vast starry sky.

If pilots are made of gold, then the equivalent value of astronauts is comparable to diamonds.

"Everything has a case, overlord, come to us to daydream, suppose you sign up to become a preparer through the primary selection, and then go through the centralized selection and re-selection, and then become a formal astronaut after the re-selection, and then train for three years and five years, maybe you will have good luck and go directly to the sky, and when the time comes, that is the nationally renowned aerospace hero." Zhou Hai said with a smile, his words were relaxed, and he had already described Su Peng's future development route, climbing to the peak of his life step by step.

"I can only dream, I thought about it, and I won't sign up for the time being." Su Peng sighed, his worries were still not dispelled, he shook his head, and said, "By the way, zero, do you have any idea to sign up for astronauts?" ”

Compared with the illusory astronaut hero honor and title, he thinks that it is still real to fly the J-20, and after a few years, maybe the Pengcheng base will be replaced with the latest improved J-20.

From a personal point of view, Su Peng feels that he is still young, and it is not too late to sign up as an astronaut after experiencing the feeling of the J-20 'Weilong' soaring into the sky.

After all, the astronauts who signed up for this time completely followed their own independent wishes and never forced them.

When Zhou Hai heard this, he was self-aware, and said slowly: "Yes, but it is estimated that the astronaut brigade does not want me." ”

In the words, there is a trace of regret.

If nothing else, he has basically no chance of becoming an astronaut.

As for embarking on the road to conquering the starry sky, this is not necessarily, with the development of aerospace technology and space technology, space fighters may be developed in the future.

"It's true that you guy's food is too much, and if you go on a long-term mission, the Shenzhou spacecraft needs to carry more food." Su Peng thought of Zhou Hai's appetite, and an irrepressible smile poured out, and the faint sorrow and regret in his heart were washed away.

Eating too much is a funny and cruel reason to refuse.

When the spacecraft is launched into the sky, in order to prolong the time in the air as long as possible and complete the important mission, every gram of payload is precious.

With Zhou Hai's terrifying food exceeding that of ordinary people, it is bound to carry more food, thereby reducing the carrying weight of scientific research equipment.

And this situation is unacceptable.

"Overlord, but if you want to become an astronaut, you have to solve the problem of being single first." Zhou Hai smiled, also poked open Su Peng's wound, and sprinkled a handful of salt by the way.

“……”

Silence fell within the radio-encrypted communication channel.

Su Peng didn't want to continue talking at all, and chose to keep quiet.

Time gradually passed, and more than 10 minutes later, the two J-10D 'Fire Dragons' crossed a distance of nearly 200 kilometers and arrived at the target airspace over the mountainous areas in the northwest of Sichuan Province.

Il-78 tankers, equipped with four D-30KP-2 high-bypass ratio turbofan engines, are already quietly waiting in the target airspace at an altitude of 4,500 meters, flying smoothly along an elliptical trajectory, with the vertical tail painted with the dazzling and distinctive August 1 logo and the official number of the Air Force.

"Zero, reduce the altitude, prepare to converge on the rendezvous, refueling at a speed of 500 kilometers per hour." Su Peng's face was serious, he pressed the lever forward, lowered the altitude and speed, and said to Zhou Hai.

It's just like that, but Su Peng takes everything very seriously and has no contempt.

"Zero received, is lowering altitude, preparing for rendezvous." Zhou Hai's voice was solemn, his right hand held the rod, and the No. 008 J-10D complemented each other, facing the behemoth in the airspace below.

The comprehensive flight data of the whole army is linked to the relevant flight data and refueling instructions transmitted by the tanker, and all of them are presented on the central multi-function screen, outlining a green section that allows refueling.

The green line belongs to the refueling section, and the red line is the section where refueling operations are prohibited, which is simple, direct, clear and clear.

The weather is cloudy, the airspace climate and environment are poor, and the sun is almost gone.

Steadily reduce altitude and speed, and dozens of seconds later, the two J-10Ds entered the core area of air refueling and came to the airspace behind the Il-78 tanker, maintaining a slightly faster flight speed and approaching smoothly.

"Buzz!"

The four engines running at the same time spew out a steady stream of high-temperature air like water pumps, and together with the horizontal and vertical tail and aerodynamic layout that rise high, they form a vortex in the airspace behind the fuselage.

In the middle of the belly, a soft refueling hose like an earthworm has been released, and a funnel-shaped refueling docking probe is installed at the end.

"Call Zero, I'm Cow One, I'll allow you to start refueling." In the encrypted radio channel, the command of the mission commander of the Il-78 tanker was heard.

"Zero has been received, ready to get closer to docking."

Zhou Hai replied, staring at the refueling docking probe more than 100 meters away, relying on the flight experience accumulated in thinking simulation, holding the rod with his right hand to adjust the angle of the canard, stabilize the attitude of the aircraft, and resist the influence of air turbulence and the vortex area of the Il-78 tanker.

The J-10D, which was shuttling in the faint clouds, accelerated forward and gradually approached under the close gaze of Su Peng and the tanker operator.

Fifty meters.

Thirty meters.

Ten meters.

"Ding!" The J-10D almost did not stop, the metal refueling pipe at the top of the nose and the refueling docking probe composed of the same metal material, accurately docked, and the whole process was smooth, fast and stable.

The fuel dispenser operator, who was still worried, was stunned and felt a little dazzled: "This is connected?" ”

PS: I'm sorry last night, I was too sleepy, as soon as I closed my eyes, I went straight to this morning.

This is yesterday's, and it is still today.
