The Start Of Technology Live Broadcast To Build Rockets

Chapter 15 – Recover a hundred tons of rockets!

The tongue of fire spouted from the bottom of the rocket, and the Long March 5 rocket flew straight into the sky.

One second, two seconds, three seconds, the Rockets were safe and sound, without any accidents. At this moment, the sky is cloudless, only one rocket rushes into the vast space!

In the command center, everyone’s expressions eased slightly. During the rocket launch process, the first ten seconds are crucial.

Most launch accidents happen at this time! But now they can’t take it lightly. According to the plan, they have to wait for the rocket to send the Tianwen-1 to the cross orbit of the earth and Mars to be considered successful!

The audience in the live broadcast room can’t wait any longer, and they have swiped their messages on the barrage.

“Thank you for the rocket sent by Lao Tie!”

“What a big firework!”

“awesome!”

“Put the noodles!”

“Fly so fast! I’m almost out of sight!”

Du Xingyu’s mobile phone has limited shooting effects, and I can’t see clearly. The rocket that is nearly 60 meters high has turned into a small black stick in the screen after ten seconds, and I can’t see it clearly if I don’t look closely.

Du Xingyu said: “Everyone, let’s go to the command center now.”

He hurried to the command center, the rocket was still taking off, but the recovery of the rocket was about to begin.

He Jingcheng stared at the screen nervously and asked, “There are still ten kilometers, get ready!”

Du Xingyu explained to the audience: “Our Long March 5 Yaosi rocket this time is a three-stage rocket design. When it lifts up to 70 kilometers, the first-stage rocket body will automatically fall off. This is the most important thing in rocket recovery. The most expensive engine is on the first-level arrow body!”

There is also a large screen in the command center, on which are satellite photos and images from the rocket’s internal camera, so you can see it more clearly at this time.

“At the 94th second of lift-off, the first-stage rocket engine shuts down, and the first-stage rocket body begins to separate!” In the command center, the electronic sound of the intelligent system sounded.

In the picture, the lowermost stage of the rocket will fall off automatically, and it will fall directly from an altitude of 70 kilometers!

At the same time, the second stage rocket engine started to ignite, and the rocket body continued to lift off!

“Is the recycling platform ready?” He Jingcheng asked.

“It’s ready, the recovery platform is open, and the sea fishing boat is in place!” Tao Ran said solemnly. Although he did not agree with Du Xingyu’s plan at the beginning, he did not slack off when he was actually working.

Du Xingyu said to the audience: “Rocket recovery is dangerous. With such a large rocket body falling from a height of 70 kilometers, if the recovery fails, the power is equivalent to dropping a missile!”

“So the recovery platform is built on the sea to avoid danger, let’s just watch the monitoring screen!”

He pointed the camera of his cell phone at the surveillance screen of the command center. In the sky, the first-stage rocket body weighing several hundred tons was still falling rapidly.

This is not comparable to the Xingkong-1 model launched by Du Xingyu. With its gravitational potential energy, if it were in the original square of Hang Da, it would be able to blow up the square directly!

On the barrage, the audience became worried: “Drop so fast?”

“Get out of the way, let me catch it!”(Read more @ wuxiax.com)

“Can you catch it? Haha, I’m afraid it’s not being smashed!”

“As everyone knows, people cannot be generalized. In extreme anger, I can manually catch the hundreds of tons of rockets falling from 70 kilometers!”

“Nima, I’m a slippery shovel when I go up!”

The rocket body is rapidly approaching the ground. In the command center, they constantly adjust the rocket’s power parameters to adjust the rocket’s position so that it can fall on the offshore recovery platform according to its positioning.

Seeing that the rocket is getting closer and closer to the sea, when it reaches a predetermined altitude, the automatic ignition system is turned on again.

The extinguished rocket engine restarts, and the jet flame is accompanied by a reverse updraft to curb the falling tendency of the rocket!

The first-level rocket body began to slowly descend in the air, and everyone’s nerves became tense. The most critical time is coming!

Five hundred meters, three hundred meters, one hundred meters!

The first-level rocket body of the rocket is already in front of us, and at this time, it is still doing fine-tuning of its position! Even a gap of a few centimeters may cause this recovery to fail!

“The recycling rack is open!”

“No positioning error!”

“Start to take a seat!”

The first-stage rocket body slowly landed on the offshore recovery platform with extremely slow movements. When the bottom of the rocket body fell on the recovery rack and the rocket body was stable, the rocket engine stalled for the second time.

The rocket’s first-level body fell on the recovery shelf intact!

“Successful!” In the command center, some people exclaimed excitedly.

“Great! It’s a success!” He Jingcheng couldn’t hide his joy. In the past, the rockets they launched were all dropped directly into the sea after they disintegrated in the air.

For the first time in history, they successfully recovered the first-stage rocket body, which cost hundreds of millions of dollars!

“Really successful!” Tao Ran took a deep breath. These days, his position has been shaking.

He remained skeptical of Du Xingyu’s plan, but could not find a reason to refute him!

And now, the successful recovery of the first-level arrow body lets him know that Du Xingyu’s plan is correct! This young student who has just graduated from Aviation University really did a miracle!

“Okay, okay! Come on, everyone!” Cao Liang was also very excited, he said: “The rocket is still taking off, and it’s not time to celebrate!”

“Yes!” He Jingcheng said, “The recovery of the first-level arrow body is successful, and the second-level arrow body and the fairing are about to be separated soon, ready for the second recovery!”

“Yes!” Everyone waited in full battle and went to work again.

At this time, the Long March 5 has already flown out of the stratosphere and is entering space!

In Du Xingyu’s live broadcast room, the audience also followed with excitement.

“The Jiangnan observation is normal!”

“Like the boss!”

“The tea-drinking doctor gave a gift rocket!”

“Wuhu, Niucha!”

“It’s too strong, the first level of the rocket body has been successfully recovered! I would like to call you the world’s most hardcore anchor!”

…

“The rocket has flown out of the atmosphere, and the fairing has separated!”

“The second-stage rocket engine is turned off, and the second-stage rocket body is separated!”

“The three-stage rocket engine is ignited, and the three-stage rocket is about to enter the TMI orbit (Earth and Mars transfer orbit).”

The three-stage rocket body does not need to be recovered, it will continue to move forward with the Tianwen-1 Mars probe until it enters the TMI orbit.

“Attention all, prepare to recover the fairing and the secondary rocket body!”

In the ground command center, the recovery of the second-stage rocket body and fairing began again.

The general process is the same as before, but this time it is easier than the last time. Because the second stage rocket body is smaller than the first stage, it is easier to control.

On the offshore recovery platform, the second-level rocket body also successfully landed on the recovery shelf, without the slightest error or crash!

“The recovery of the secondary rocket body is successful!”

“Successful recovery of fairing!”

“I declare that the rocket recovery has been successfully completed!” He Jingcheng shouted in the command center!
