Chapter 32: The Wind
"Damn, the tractor factory really doesn't stop for a moment."
"The surname Lin is like taking an aphrodisiac, there are more new tricks in a few months than we have in ten years, new rockets are pulled out and fired, and if the test is not done, it will be recycled, is there such a thing in aerospace."
"If you want me to say, young people have to suffer a little......"
The Eighth Academy, He Ruo and the leaders of the Sixth Academy hid in the office to watch the live broadcast of the Xinyuan No. 1B launch.
Both of them have a lot of grievances, one is that they were dug by Lin Ju, and the other is that the project was crashed and crushed by the cost.
They were originally discussing the cost control of YF100 and Changliu after the minor change, but they happened to encounter the live broadcast of the launch, so they simply started to be an online audience, and they did not forget to quietly DISS Lin Ju.
I don't have any good words to say about you, but Mr. Zhao suddenly thought of the K120's extremely high performance, and suddenly said:
"What if this recovery succeeds?"
"Success? It's not that you didn't participate in the dozens of seminars before, and we haven't studied rocket recovery for so many years, what is the result?
This road will not work at all, and when the Tengyun project is successful, they will know who is the right path as soon as the aerospace plane comes out! Reusable rockets are a trick of an Aramco businessman to cheat investments, the capitalists don't understand, we don't know yet? ”
"What if, I mean?"
"What if?" He Ruo imagined it for a moment, and suddenly a spirit shook his head violently.
"Impossible, this is only the first experiment, and when he succeeds, the space plane will come out early."
When will the space plane come out? The current plan for the space port is 2025, that is, at least ten years!
Chief Zhao stopped talking and looked at the screen, not knowing what he was thinking.
……
"Lao An, you tell you the truth, is this thing really reliable?"
Outside the launch site, Zhou Rui, who was wearing an integrated training suit, quietly asked Anderov, a system engineer.
"Of course, the X1B uses the latest control technology, and I am 101% confident."
Anderov certainly didn't believe it according to the original trajectory, but when the institute embraced C-class recycling technology, they became extremely determined, and no one knew the system better than them.
Zhou Rui shook his head, thinking that Mao Zi looked quite honest, but he didn't expect it to be radical, so he was here to make a big leap forward in technology.
"Wait a minute, there are still 15 minutes to launch, and I am very confident in the rocket I designed."
"Good luck Anderov."
In the control room, Lin Ju had stopped interacting with netizens, and his face staring at the screen slowly had a serious expression.
Although he was confident in the system, he was still a little nervous about the failure of the empty fork again and again, knowing that the reason for his rebirth was also because the runaway starship smashed down.
The barrage comments on the screen on the side are still beating rapidly, and the number of viewers has exceeded 150,000 at this time.
The fugitive liquid oxygen swirls around Xinyuan No. 1B, like a dragon carved on a stone pillar, as if it is about to break through the sky.
"Countdown, thirty seconds!"
Since the take-off weight of the rocket is only 100 tons, the launch tower is just a simple base, and the rocket stands completely on its own weight.
This time the first flight did not carry a load, the second stage is a fake model, anyway, the technology is the same as the second stage of the Xinyuan 1, simply save some trouble.
"Fifteen seconds!"
In the live broadcast screen, the countdown in the lower left corner keeps jumping, and on the launch track in the middle below, the icon representing the rocket flashes and glows white.
"Ten, nine, eight...... Three, two, one, ignition. ”
The live stream switches to a camera on the deflector, and the engine in the center of the screen begins to tremble as hundreds of thousands of horsepower turbopumps run, spewing out an orange flame.
The throttle valve slowly increased the pressure, more and more fuel entered the combustion chamber, and when it reached 75%, the engine thrust exceeded its own weight, and the rocket broke away from the launch tower.
The picture is covered in a large field of flames from orange.
Xinyuan No. 1B dragged twice as long as itself, gradually transitioning from orange to blue flames, and flew towards the sky with extremely high acceleration.
The launch control room was silent, staring at the rocket's flight attitude without blinking, and constantly reporting the data of one sensor after another.
The comments in the live broadcast room also decreased rapidly, and everyone knew that the highlight was behind, 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 screen, the rocket stick figure represents the fill white of the fuel and a little bit of the bottom layer.
In the camera at the top of the first stage, the four pneumatic grille rudders above the first stage unfold and begin to turn.
At this time, the rocket enters the turning procedure after launching, and the attitude of the rocket body is lying horizontally, so it must be returned to the center as soon as possible to avoid the deformation of the rocket body caused by too much pressure on the side.
The shell of the rocket is very thin, the axial direction can withstand a large overload, but the radial direction is very poor, once the attitude is sideways, it is easy to lose control and enter the roll, then it is completely impossible to correct.
But the four-piece grille rudder rotates flexibly, allowing the rocket, which is beginning to fall naturally, to slowly swing vertically through aerodynamic pressure.
Because the engine at the bottom is very heavy, the first stage center of gravity with only a little fuel left is very low, so once it is erected, it can rely on gravity to return to the value on its own, and only needs the grille rudder to act slightly to keep the attitude stable and not shake violently.
In this way, the descent by gravity is no slower than that of flying, and the altitude of the rocket, which was still at the edge of the atmosphere, decreases rapidly, and the altitude number on the live screen decreases at an alarming rate.
"It's so fast, I can't slow down and crash."
He Ruo, who was in front of the computer, calculated the decline rate in his heart, and saw the serious but still controlled expressions of everyone in the control room, and he was secretly surprised in his heart.
When the altitude dropped to 7,000 meters, the tracking camera on the ground had already captured small white dots.
The rocket falls vertically as if it was launched, but in the opposite direction.
5000 meters, 3000 meters, 2000 meters, 1200 meters, 1100 meters.
The live broadcast became two, one was the entire rocket that had been clearly captured by the ground camera, and the other was the camera above the engine.
At 1000 meters, the K120V ignited again.
In just two or three seconds, when the altitude fell to 900 meters, people outside the launch site could already see the rocket re-ejecting a long tail flame.
In the live footage, the rate of altitude drop finally begins to slow down, but it is still rapidly falling to the ground.
He Ruo was already extremely surprised when he saw this, because Xinyuan No. 1B really successfully controlled the rocket near the landing site through the adjustment of the grille rudder, which is already a very powerful technology.
The engine continued to work, and at this point the role of the aerodynamic grille rudder began to decrease, but the rocket was still a long way from the X in the center of the landing point.
In the camera above the engine, the nozzle began to swing non-stop in a range of 25 degrees, pushing the slower and slower descent of the rocket towards the center of the landing field.
Lin Ju's back had already left the sofa at this time, and his eyes were looking at the rocket whose posture was becoming more and more stable, and his heart had already begun to settle down.
Just when he thought he was close to success, the rocket's attitude suddenly tilted sharply, almost lying down and accelerating down.
Everyone in the control room was suddenly startled, and he subconsciously shouted, sitting nervously sweating in front of the computer:
"Wind!"
