Chapter 615: Perfect

People Jeb. Although Mr. Bush can be here at such a juncture, although there are many political purposes, it is undeniable that Jeb Bush can be here. The arrival of Bush has given this launch mission a more profound political significance.

Although in the current polls show that Jeb . Bush is also slightly behind Hillary. Ms. Clinton, but after all, the final campaign speech has not yet begun, the final voting has not begun, everything is possible. Moreover, in the history of the U.S. presidential election, there are also cases where they were inferior to their competitors in the early stage, but finally won the final election in one fell swoop.

Therefore, before the final result comes out, the little Mr. Bush with eyes in front of him is the future president of the United States.

Under the leadership of Tang Feng, Jeb. Bush met with the personnel of the space agencies of various countries, and finally met with Dr. Schmitz, the chief engineer of the mission, and after saying many words of encouragement, he left the control center accompanied by a group of personnel. After all, it is not a good place to watch the rocket launch in the control center, and the best place to watch the rocket launch is from a specially set up viewing platform a few kilometers away.

Sent off Jeb. Bush and his entourage, Tang Feng grabbed Dr. Schmitz and said, "Doctor, how sure are you about this launch mission?" ”

Dr. Schmitz pointed at Tang Feng with a smile and said, "I knew you weren't at ease." Well, let me tell you the truth, I am more than ninety percent sure that this launch mission can be successfully completed, but how far the rocket recovery can be achieved still depends on the specific performance of this rocket today. ”

After a pause, Dr. Schmitz pointed to the situation on the launch stand displayed on the big screen and said, "No one dares to say that there is a complete certainty of launching this kind of thing, but Don, I have done everything I can to the extreme." So in my mind, there will be no problem with this launch. ”

Tang Feng nodded and said, "Doctor, I believe in you and your team very much, but this time it was launched with a payload, and the attention is so high, I, an investor, are really a little uncertain." ”

Dr. Schmitz patted Tang Feng on the shoulder and said, "Tyrant." You can rest assured, there is a great possibility that this launch mission will be completed perfectly. I don't know how to comfort you, but I'm confident that if you say something like that, in two hours, I'll be right! ”

Tang Feng smiled and nodded, and sat down in the relevant seats with Dr. Schmitz, waiting for the final moment to come.

One hour and fifty minutes later, with the end of the 10-second countdown, the "Starry Sky No. 1", which carried the hopes of countless people, once again erupted a strong jet. After less than 100 seconds, with the prompt sound of "the first-stage rocket engine is closed, the first-stage rocket is successfully separated, and the second-stage rocket is successfully ignited" issued by the control center, all the people on the scene cheered excitedly.

At this time, the second-stage rocket with the payload had already crossed the altitude of the Kármán line, and in the most important atmospheric flight phase, the performance of Starry One-one was undoubtedly good. Everything is exactly as pre-programmed.

At this time, it is difficult to see clearly how the separated rocket is running through the naked eye, and you can only watch how the separated second-stage rocket continues to accelerate the rocket through the large screen.

And the detached first-stage core-stage rocket body. It also began to draw a large upward parabola in the air under the action of inertia, and finally began to fall towards the ground under the attraction of the earth's gravity.

From the moment the first stage of the rocket separated, Dr. Schmitz's team split into two teams, one of which continued to track the operation of the second stage. Another team focused all their attention on the recovery of the first-stage core-stage rocket body.

Tang Feng's attention was not on rocket recovery at all, he was more concerned about the operation of the second-stage rocket.

When the second stage rocket is ignited, the rocket body has reached the altitude above the Kármán line, and the flight in the densest atmosphere has ended, but at this time. The speed of the rocket is still far from the speed that can break free from the gravitational pull of the Earth, so the second stage rocket needs to continue to accelerate for the rocket.

However, after flying past the Kármán line altitude, the atmosphere has been much thinner, and the final first-stage core rocket has been detached, which reduces the weight of the entire rocket by more than 80%.

After the two-stage rocket worked for about 80 seconds in ignition, it has pushed the rocket body to an altitude of 200 kilometers from the ground, and the speed of the rocket has reached the predetermined speed at this time, and at this time, the rocket has basically flown out of the atmosphere, so according to the preset program, the first thing to abandon is the rocket arrow fairing, and then the second-stage rocket engine is closed and separated.

At this time, the remaining tripolar rockets and payloads actually have the speed to escape from the earth's gravity, because the rocket at this time has quite strong kinetic energy, so under the action of the earth's gravity, the rocket body begins to enter the inertial flight stage, until it is tangent to the predetermined orbit of the core functional module of the lunar spacecraft, and the third pole rocket engine begins to ignite and enters the final acceleration stage of flight.

This stage takes a few minutes, and when accelerating to a predetermined speed, the third pole rocket engine shuts down, and the core functional module of the lunar spacecraft is ejected from the rocket launch vehicle into a predetermined orbit.

At this time, the entire rocket launch mission can be regarded as the final completion.

And all this, the Starry Sky 1 heavy carrier rocket has been completed perfectly, there is not even a little mistake in the middle, and the fatal mistake of the most prone tripolar rocket engine ignition failure has not appeared, so when the final core functional module of the lunar spacecraft was ejected from the rocket body of the tripolar rocket, the audience once again resounded like thunderous applause.

In fact, at this time, five or six minutes have passed since the successful landing of the first-stage core-stage rocket body of the "Starry Sky No. 1" again. In fact, before the ignition of the tripolar rocket engine, the first-stage core rocket body that fell from a height of 100 kilometers has successfully reappeared in the state of the last recovery experiment, and under the preset program control, the rocket body weighing dozens of tons has once again perfectly achieved a vertical soft landing.

When the core functional module of the lunar spacecraft successfully entered the predetermined orbit, the rocket launch mission achieved a perfect launch result.

Although it is only a real launch, it means that the "Star-1" heavy-lift launch vehicle has the function of repeated use many times, and in less than three months, the "Star-One" heavy-lift launch vehicle has completed two vertical soft landings in succession. (To be continued.) )
