In parallel with the press interview, there was also the inspection of the final stage of the Yinglong heavy launch vehicle.

At 12:30 Yanjing time, there was still half an hour before the launch.

The 69-meter-high, 20-story giant rocket is standing proudly on the launch pad at this moment.

If you look at it from a distance, Yinglong Rocket is dressed in snow-white paint, with a bright red rectangular pattern on the top, which is the flag of China, and it is also like a dragon's eye.

At this moment, Yinglong Rocket is diffusing a billowing white mist of water vapor, which is in response to the scene of soaring clouds and fog in myths and legends.

In the media live broadcast room, Chen Liang, chief engineer of Muyu Aerospace, is still introducing relevant details to everyone.

"Yinglong heavy-duty launch vehicle adopts the containment release technology, what does it mean, that is, before the rocket erects the launch pad and ignitions and takes off, the rocket is restrained by the containment release system integrated in the launch pad, and at the same time, the rocket engine is erected and the launch pad works under low working conditions for a period of time, and some of the main sensitive parameters of the engine are collected and evaluated and analyzed. Well, to put it simply, it is to light the fire lightly, drag the rocket, and then observe it for a while, and then let it fly freely when it is okay, which can improve the safety and reliability of the rocket launch. ”

"Muyu Aerospace's engineering team is putting the finishing touches on the three Chongmingniao engines, and now is the critical moment to decide whether the launch will proceed."

"What does Chief Engineer Chen mean, the launch of Yinglong's rocket may be terminated?" A media reporter on the side asked.

"No, no, no." Chen Liang waved his hand again and again, "Not being able to launch is an extreme case, a small probability situation." ”

In the face of this interview, the live broadcast network exploded again.

[How can this Chief Engineer Chen be a good Yazi who has no confidence!? 】

[That's, that's it.] 】

[Before the launch, I started to find excuses to find steps, and it seems that I have no confidence. 】

[Keyboard warriors are harsh, people are just more rigorous. 】

……

Chen Liang wiped his sweat, as the chief engineer of Muyu Aerospace, he knows his own products very well, although he is full of confidence in the Chongmingniao No. 1 engine and Yinglong heavy launch vehicle, but there are too many variables in rocket launch, and no one dares to pat his chest and say 100% success.

In other words, the Falcon of Space X was blown up 3 times in a row before the test launch was successful.

Looking at the powerful national teams in the world, who hasn't blown up a big firework isn't!

And this time, Mr. Hua arranged for him to deal with the media, which was really a bit embarrassing for himself.

He has no words about old Chen technology, and he is not afraid to work, but in the face of the long guns and short cannons of the news media, it is indeed a little pee (sui, the first sound).

But before coming, Mr. Hua patted him on the shoulder very confidently and said that although you can rest assured, you can play casually.

So what to do, the boss said to play casually, we have to work hard.

So Chen Liang had no choice but to adjust his heartbeat, with a smile on his face, and continued to introduce in a slow tone.

"After 36 seconds of takeoff, the boosters on both sides will start to reduce power, which is to prepare the rocket for maximum aerodynamic loads. Once you get through this phase, the boosters on both sides will return to maximum power again......"

"After about another minute, the boosters on both sides will reduce the thrust again, this time to reduce the force on the rocket's structure. At this stage, the weight of the rocket decreases because a large amount of propellant has already been consumed......"

"About 2 and a half minutes after Yinglong takes off, the boosters on both sides will be completely turned off, and the hydraulic separation device of the center rocket will be activated, unlocking the thrusters on both sides and pushing them away separately."

"The head of the two thrusters is separated from the core stage rocket first, and then the roots, so that they naturally turn out from the middle to the sides and enter the recovery link."

"Chief Engineer Chen, is Muyu Aerospace confident in the recovery mission of the Yinglong rocket?" The moderator asked again.

"Sure enough!"

"I'm sure you've noticed, and now many people on the live broadcast network are asking, what is the difference between our Muyu Aerospace's rocket recovery technology and Space X Company?"

"In fact, the use of rocket recovery technology is basically the same, of course, due to launch conditions and geographical factors, we will have some differences, our specific arrangement is like this......"

……

After another introduction, the time was approaching 13:00.

The popularity in the live channel has also reached its peak.

According to the real-time statistics of major mainstream live broadcast platforms, the number of people watching Yinglong's heavy-duty launch vehicle online around the world has exceeded two million at this moment.

Most of them are professionals, and there are also some people who come to eat melons.

There are local audiences in China, as well as peers from all over the world, or some aerospace enthusiasts.

Some people are full of excitement and anticipation,

There are also people who are full of doubts and even mockery.

Some people expect success in one fell swoop,

There are also people who wait for the final blow up in the air.

In the last 3 minutes of the launch stage, the live broadcast screen immediately fully cut to the launch platform.

At this moment, the white mist was still rolling around Ying Long's rocket, and the water vapor was rising.

The final preparations for launch are being broadcast in the monitoring system:

"The first stage rocket has completed the delivery of liquid oxygen......"

"The liquid oxygen delivery port of the second-stage rocket is closed ......"

"Vector thrust control motion of the two-stage rocket is normal......"

"Center Rocket Lock Completed ......"

"Positioning plate locks the end of the preparation of the second stage rocket......"

"Yinglong rocket began to turn to internal power supply ......"

"The rocket adjusts itself, the ground delivery valve begins to close, and the rocket gas delivery is completed......"

"The self-inspection of the three Chongmingniao No. 1 engines has been completed......"

"Automatic Flight Termination System Ready to Complete ......"

"Ground Gas Transfer Valve Completely Closed......"

"The Yinglong heavy launch vehicle is ready for launch."

……

Seeing that there were only 30 seconds left on the launch countdown board, the entire live channel exploded.

Full of barrage, the screen is densely packed in an instant.

All kinds of words flew by, and it was simply dizzying.

"15 seconds from launch!"

As the system announced, a burst of cheers and screams suddenly erupted in the video message at the launch site.

This must have been the sound of the crowd watching the scene, and the sound pressure was almost bursting through the screen.

"The countdown to launch begins."

“10…… 9…… 8…… 7……”

In a burst of cheers, the people at the scene began to count the seconds in unison.

About 8 seconds into the countdown, the entire screen content of the live video began to shake.

That's Ying Long's rocket roaring on the ground!

So much so that cameras in the distance were affected.

“6…… 5…… 4…… 3…… 2…… 1…… Launch! ”

After the countdown was over, I saw a fierce flame suddenly lit up at the bottom of the rocket, and in an instant, the billowing smoke spread out from the rocket launch pad to all sides.

Surrounded by clouds and smoke, Ying Long rose into the air and rose from the ground!

Cheers, screams and screams!

The audience who watched the live launch also exploded.

[Rush! Come on! 】

[Ahh Yes! Yes! 】

[Why am I not there!? 】

[Up, up!] 】

[Come on! 】

【Fried !! 】

【Fried fried fried !! 】

[Explode!] 】

【it!】 】

I saw that Yinglong's rocket was flying faster and faster, breaking through the clouds and fog!

The monitoring system also began to broadcast the real-time flight of the rocket.

"The Yinglong heavy launch vehicle began its test flight and flew into space!"

"The rocket is ready for maximum dynamic pressure and is about to reduce the thrust."

"The rocket reaches supersonic ......"

"The boosters on both sides returned to the maximum power, and we passed the stage of maximum pressure on the aircraft!"

[Rush! Come on! 】

[Come on! 】

[Envy the people who watched live.] 】

【Fried fried fried !! 】

[Why doesn't it explode yet!?] 】

……

At the same time, outside the safe distance of the rocket launch platform, Li Chenjing, Lu Jieshi, Mao Xianyu, Xiao Wangran and other relatives and friends who came to watch the rocket launch were tearing their voices and cheering.

Unlike other melon-eating people, this rocket is definitely their own son!

Li Chenjing and the others waved their arms hard, and the Ying Long rocket flew higher and higher, faster and faster.

Hua Kejing also stood in the crowd with a happy face.

He was also excited, but unlike other field engineers, Wacovision was not nervous at all.

The rocket launch mission was successful, as was the recovery of the two boosters and the core-stage rocket.

He has demonstrated all this several times in the computational model.

So at this moment, what he needs to do is to wait quietly and wait for Muyu Aerospace Technology to complete this wonderful aerospace debut.

Hua Kejing's heart is extremely emotional.

In order to complete the B001 and B002 missions released by Xiaole, he has almost exhausted all his resources in the past year.

In the initial stage, although the [Scientific Research Institute] and the [Engineering Research Institute] successfully designed a new liquid rocket engine scheme that is closest to the current stage, it is a technology that exists in the virtual world after all.

In order to put the design of the Chongmingniao No. 1 engine into reality, Huake Jing contacted more than 100 suppliers non-stop.

In order to obtain support in the production process, he used nearly 100 computational models to negotiate and communicate.

36 joints have been opened successively, and only then have they received the support and help of various key institutions and groups.

When Muyu Aerospace successfully manufactured the rocket engine, Xiaole immediately released the B003 mission - the rocket test launch.

And then another mess.

But fortunately, the rocket engine is the core of the whole rocket, and after getting the engine and then manufacturing the rocket, the whole process will be much smoother.

After all, many insiders in the bureau are full of expectations for the new liquid rocket engine of Chongmingniao No. 1, so after determining the cooperation plan, all parties have given great help to the design and manufacture of Yinglong rocket in the later stage.

This finally created the results of today's Yinglong liftoff.

I salute every friend who has been with me all the way, thank you for your support!
