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

It's wind, a strong cross wind caused by rapid changes in temperature caused by thermal airflow when approaching the surface!

Lao Ma's Falcon 9 has been defeated by this many times!

Ah Mei, Lao Ma, who was watching the live broadcast, almost suspected that a miracle was about to happen - just like every time he watched the end of Falcon 9, but at this time he also knew that it was just another natural failure.

Because the rocket was only 400 meters away from the ground at this time, the tilt angle had exceeded the rocking angle of the rocket engine and it was impossible to adjust it.

Lin Ju's hands were about to hold bleeding marks, and he felt very unwilling. At the same time, he felt regretful: Could it be that he was really too radical and the system was not omnipotent?

However, Guo Shen, who was away from the control room, put his hands on the console. Although his face was gloomy, he did not look like he had failed. He just whispered to himself in a voice that only he could hear:

"There's still 4% fuel left, that's enough, that's enough."

At this time, outside the launch site, the sharply tilted rocket seemed to be about to fall to the ground. Everyone was about to feel sorry when they suddenly heard an explosion.

It is a circle of ultra-small solid rocket motors buried at the top of the rocket, with its axis perpendicular to the rocket and distributed in a fan shape.

They are divided into three layers, ensuring that there is one in each radial direction, which can be instantly ignited to produce a short but powerful thrust and quickly correct the posture.

This technology is commonly used in missiles. Every time friends who like the military look at the missile, it is clear that the vertical launch speed is very high, but suddenly changes to the horizontal direction at high altitude. This is because the micro solid engine installed on the rocket body sprays out powerful flame violence. Change posture.

RCS (Reaction Control System), which sprays nitrogen and other gases, is commonly used on rockets. It is softer but has less instant thrust and is easier to control.

But at this time, it is obvious that the miniature solid motor is more useful, and can complete the change of the rocket's attitude in a few seconds.

The rocket that was originally tilted at a large angle immediately swung in the opposite direction, and then the solid motor at the other end started. Before it burned out, the remaining solid motor on the opposite side also started. The two-way action re-fixed the attitude of the rocket in a vertical state.

At the same time, the throttle of the rocket engine at the bottom expanded, and the suddenly expanded thrust caused the rocket, which had fallen outside the launch site and was only more than a hundred meters above the ground, to drop its descent rate to only two or three meters per second, almost stopping in the air. .

Then the engine nozzle swings slightly again, controlling the rocket to slowly descend while moving toward the landing site.

This process is very complicated, but the total time it takes place is no more than 5 seconds, and it has brought the first stage rocket back to life and saved it.

Chief Zhao next to He Ruang slapped the table and stood up, leaning over as if to put his head into the screen to take a closer look.

This time there were no accidents. The tilted tail flame at the bottom of the rocket returned to normal a little bit, and then gradually closed the throttle valve. The height of the rocket dropped little by little amidst the vibrations and sound waves of the bombardment on the ground. The rising heat wave made the camera capture the scene There's a big twist.

100 meters, 50 meters, 30 meters, the attitude of the rocket remains unchanged, and it steadily decreases in altitude.

20 meters above the ground, the four support legs are smoothly unfolded under the action of hydraulic cylinders, so that the end is lower than the engine nozzle.

In Lin Ju's heartbeat that seemed to tear his chest apart, the engine's tail flame became smaller and smaller, and it shut down when it was less than one meter above the ground.

The four supporting legs immediately touched the ground. The 33-meter-high core stage vibrated due to its own weight when it fell to the ground, but it quickly stopped under the action of the elastic supporting legs.

The live broadcast screen finally cut to the landing site. At this time, a white rocket whose appearance was ablated by the atmosphere and tail flames and looked like peeling paint spread out its four black claws, perfectly blocking the center of the X-shaped landing point.

Lin Juxiang fell heavily on the sofa, covered his face with his hands and took a deep breath.

"Success, success! Ahhh!"

"屮, 屮屮屮屮!"

The originally quiet control room was flooded with crazy cheers, which almost pierced Lin Ju's eardrums, but he didn't seem to hear it, clenching his fists and waving continuously.

This time, he made history!

Not only was Xinyuan No. 1B successfully recovered, but it also made a real comeback against the wind, using its ridiculously powerful flight control to save itself from the edge of crashing.

This not only proves that vertical recovery is feasible, but also shows that its anti-interference ability is not bad at all, and is even more stable than common sense.

"Old boy, look, it's successful. This rocket is actually successful! Haha."

Zhou Rui watched Rocket keep pulling Tong Peiqiang next to him, but he only heard vague sounds of um um ah ah.

"Ah, old Tong, what are you doing... Someone come here quickly, Director Tong has dislocated his jaw!"

But his shouts were drowned in loud cheers, and it took a long time for the doctors from the clinic to come over and take Director Tong away.

Zhou Rui turned to shake Androv's shoulders: "Look, the Chinese have successfully recovered the rocket!"

Androv was expressionless: "Zhou, I am a Tatar. I have the same origin as Mongolia, not a white person. And now I am Chinese. I also designed the rocket, so it should be us."

"Haha, yes, it's us!"

In the office of the Vice President of the Eighth Hospital, He Zhuang lay on the chair and muttered to himself as if he had drained all his strength:

"Impossible, this is unscientific. Is it really that we are too conservative and dare not take a step forward?"

Chief Zhao, who was also shocked, shook his head and said:

"The sky is about to change in the aerospace industry. It is feasible to recycle rockets. Even if they are reused 10 times, the cost will be reduced by more than 80%... We are about to live. Reusable rockets will completely change everything.

His grandma's had so many meetings, but it wasn't as fast as ten minutes! "

On the other side of the ocean, Lao Ma looked at the core first-stage rocket frozen in the center of the screen. He listened to the sweet host who had no idea what it meant and only knew that it was very powerful. He continued to explain without any nutrition, and crossed his hands to support his chin.

"President."

The assistant reminded him to pay attention to his mobile phone, which showed the interface of Little Bluebird, and now countless people were going crazy @老马.

No need to think about it, he knew what it was about.

"Scott, when is our next scheduled rocket launch?"

"It will be launched at Cape Canaveral Air Force Base in January next year." The assistant replied respectfully.

"Are you confident this time?"

Seeing Lao Ma's unclear expression, Scott quickly said:

"There is no need to be upset, sir. We have collected data and the flight control is being further improved..."

"Okay," Lao Ma interrupted him, closing his eyes for a few seconds and then opening them again, his eyes filled with determination again.

“It’s really frustrating for a small Chinese private aerospace company to suddenly appear and accomplish what I haven’t accomplished in ten years... maybe it’s just frustrating, I admit it, especially if it succeeds the first time.

But this also just tells me that we are right, and specaX is not far behind, only a little bit. As long as we work harder, we will definitely succeed. The biggest fear in scientific research is not knowing whether it will succeed. Now that we have changed from pioneers to followers, we should take advantage of being latecomers and catch up quickly.

From now on, we will produce one Falcon 9 rocket a month and launch one every month until we succeed. We have thousands of employees, the most powerful production capacity, and the support of the space agency. Scott, we will succeed, we will! "
