I ask you to build tractors, but you build rockets?

"Damn, the tractor factory really doesn't stop for a moment."

"The guy named Lin is like taking an aphrodisiac. He has made more new tricks in a few months than we have in ten years. New rockets are fired as soon as they are pulled out, and they have to be recycled if they are not tested. Are there any people in the aerospace industry like this?"

"If you ask me, young people have to suffer a little bit..."

In the Eighth Institute, He Ruang and the leaders of the Sixth Institute hid in the office to watch the live broadcast of the Xinyuan-1B launch.

Both of them had a lot of grievances. One was poached by Lin Ju, and the other was because the project was crashed and cost crushed.

They were originally discussing the YF100 minor modifications and the cost control issues of Changliu. It happened to be the launch live broadcast, so they simply became an online audience and did not forget to quietly diss Lin Ju.

You and I have nothing nice to say, but General Manager Zhao suddenly thought of the extremely high performance of the K120 and suddenly said:

"Then what if the recycling is successful?"

"Success? It's not like you didn't participate in the dozens of previous seminars. We haven't been studying rocket recovery for so many years. What was the result?

This road is totally unworkable. Only when the Tengyun Project is successful and the aerospace plane comes out will they know who is on the right path! Reusable rockets are just a trick used by an American businessman to defraud investors. The capitalists don’t understand, but we still don’t know? "

"What if, I mean what if?"

"What if?" He Zhuang imagined it for a moment, suddenly got excited and shook his head violently.

"It's impossible. This is just the first experiment. By the time he succeeds, the aerospace plane will have been out long ago."

When will the aerospace plane come out? The current plan of the Aerospace Port is 2025, which means at least ten years!

Chief Zhao stopped talking and looked at the screen, wondering what he was thinking.

…

"Lao An, tell the truth, is this thing really reliable?"

Outside the launch site, Zhou Rui, wearing an all-in-one training suit, quietly asked system engineer Androv.

"Of course Zhou, X1B uses the latest control technology, I have 101% confidence."

Androv would definitely not believe it based on the original trajectory, but he became extremely determined after the institute accepted the C-level recycling technology. No one understood the system better than them.

Zhou Rui shook his head, thinking that Maozi seemed quite honest, but he was also radical, and he was here to make a technological leap forward.

"Just wait, it will be launched in 15 minutes. I am very confident in the rocket I designed."

"Good luck to you Androv."

In the control room, Lin Ju had stopped interacting with netizens, and his face slowly became serious as he stared at the screen.

Although he had confidence in the system, the repeated failures of Kongcha still made him a little nervous. You must know that the reason for his rebirth was because of the crash of the out-of-control starship.

The barrage comments on the screen nearby are still beating rapidly. At this time, the number of viewers has exceeded 150,000. If there is a reward channel, you may be able to earn gas money.

The escaping liquid oxygen spiraled up around Xinyuan No. 1B, like a swimming dragon carved on a stone pillar, seeming to break through the sky.

"Countdown, thirty seconds!"

Since the take-off weight of the rocket is only a hundred tons, the launch tower is just a simple base, and the rocket stands completely by its own weight.

This first flight did not carry a payload, and the second stage was a fake model. Anyway, the technology is the same as the second stage of Xinyuan 1, so it would save trouble.

"Fifteen seconds!"

In the live broadcast, the countdown in the lower left corner kept beating, and on the launch trajectory in the middle below, the icon representing the rocket flashed white.

"Ten, nine, eight...three, two, one, light the fire."

The live broadcast screen switched to the camera on the diversion trough. The engine in the center of the screen began to tremble as the turbine pump with hundreds of thousands of horsepower was running, spitting out an orange flame.

The throttle valve slowly increases the pressure, and more and more fuel enters the combustion chamber. When it reaches 75%, the engine thrust exceeds its own weight and the rocket breaks away from the launch tower.

The screen was covered by a large area of ​​orange flames.

Xinyuan No. 1B dragged flames twice as long as itself, gradually transitioning from orange to blue, and flew towards the sky at extremely high acceleration.

The launch control room was quiet, with eyes fixed on the rocket's flight attitude and constantly reporting sensor data.

The comments in the live broadcast room also decreased rapidly. Everyone knew that the main event was coming later, and they all waited with bated breath.

150 seconds after the rocket ignites, the first stage engine shuts down and the second stage ejects and separates.

On the UI of the live broadcast screen, the rocket sketch represents fuel filled with white and a little bit at the bottom.

In the camera on the top of the first stage, the four aerodynamic grille rudders on the first stage unfolded and began to rotate.

At this time, the rocket enters the turning process after launch, and the rocket body is lying horizontally. It must be returned to the straight position as soon as possible to avoid excessive lateral pressure that may cause the rocket body to deform.

The rocket's shell is very thin and can withstand a large overload in the axial direction, but it is very poor in the radial direction. Once the attitude is turned sideways, it is easy to lose control and enter a roll, which is completely impossible to correct.

But the four-piece grille rudder rotates flexibly, allowing the rocket that begins to fall naturally to slowly swing vertically through aerodynamic pressure.

Since the engine at the bottom is very heavy, the center of gravity of the first stage with only a little fuel left is very low, so once it is upright, it can return to the value by gravity. It only needs a slight action of the grille rudder to keep the attitude stable and prevent violent shaking.

In this way, the descent relying on gravity is no slower than flying. The height of the rocket, which was still at the edge of the atmosphere, rapidly decreased, and the altitude number on the live broadcast screen decreased at an alarming rate.

"It's so fast, it must be unable to slow down and it will crash."

He Ruang, who was in front of the computer, calculated the rate of decline in his mind, and was secretly surprised when he saw the serious but still under control expressions of everyone in the control room.

When the altitude dropped to 7,000 meters, the tracking cameras on the ground had captured small white dots.

The rocket falls vertically just like when it was launched, but in the opposite direction.

5000 meters, 3000 meters, 2000 meters, 1200 meters, 1100 meters.

There are two live broadcasts, one is the entire rocket that has been clearly captured by the ground camera, and the other is the camera above the engine.

At 1000 meters, the K120V ignited again.

In just two or three seconds, when the altitude dropped to 900 meters, people outside the launch site could already see the rocket ejecting a long tail flame again.

In the live broadcast, the speed of descent finally began to slow down, but it was still falling to the ground rapidly.

He Zhuo was extremely surprised when he saw this, because Xinyuan-1B really successfully controlled the rocket near the landing site through the adjustment of the grille rudder. This is already a very powerful technology.

The engine continued to work. At this time, the effect of the aerodynamic grille rudder began to decrease, but the rocket was still far away from the X in the center of the landing point.

In the camera above the engine, the nozzle began to swing continuously within a 25-degree range, pushing the rocket, which was descending slower and slower, toward the center of the landing site.

Lin Ju's back had already left the sofa at this time, his eyes fixed on the rocket that was becoming more and more stable, and his heart had begun to settle down.

Just when he thought he was close to success, the rocket's posture suddenly tilted sharply, almost reclining and accelerating as it fell.

Everyone in the control room was suddenly startled. He Yuan, who was sitting in front of the computer and sweating nervously, subconsciously shouted:

"wind!"
