Vol 3 Chapter 753: Cai Ruichen is playing a little big (5 more for a reward

ps: Thanks to the "ss-skeleton division" in the fan group for the 200 yuan red envelope sent to gorgeous on qq. This chapter continues to add more for him.

In the Space Launch Center of the Future Science and Technology Group, a loud alarm sounded, and the rocket launch entered the last-minute countdown.
In the command center of the space launch center, hundreds of staff members all sit quietly at the grassroots jobs.
Hundreds of people stayed in their posts, only occupying a small corner of the entire command center. This is a satellite command organization that can accommodate at least five thousand people.
In the half-floor of the command hall, this is the key place of the entire command center. There are still a large number of posts on it, but all satellite launches are controlled by these posts.
When Cai Ruichen brought Musk here, the inside was already quite busy.
The central area of ​​the command center is a central computer display area with a diameter of fifty meters. At this moment, the image on the satellite launch platform is clearly projected here.
The lens in the projection screen is drawn very close, and the projected satellite is standing quietly on the launch platform, and the fixing frames on both sides have all fallen down and are lying flat in the groove on the ground.
In the entire launch site, there is only this solitary carrier rocket waiting to be launched. The white rocket paint clearly depicts the future technology group.
The elliptical space capsule is on the top of the missile. There are three test satellites inside, which will be released into orbits at different altitudes after lift-off.
The long carrier rocket, like the long sword against the sky, pointed at the blue sky, waiting for the final moment of ignition.
Standing with Cai Ruichen, Musk took a very careful look at the projected launch vehicle in front of him through the augmented reality projection in front of him.
It seems that there is still a big difference from the Dragon spacecraft developed by Musk himself, but there are many similarities.
The most critical part of the same place as the Dragon spacecraft is the design of the space capsule and that the rocket propeller uses the overall first-level rocket technology.
The use of this technology is to be able to send the entire launch vehicle back directly after the space capsule is put into orbit.
Otherwise, if a multi-pole rocket launch method is used, the difficulty of recovery will increase by a geometric multiple.
After all, if you want to prepare enough fuel for each stage of the rocket thrusters to return to the earth and land smoothly, and set multiple landing points, you must also replace those rocket thrusters with engines that can reignite. The cost is still It is better not to recycle.
For this design, Musk is naturally recognized, but for the future technology group without even pre-testing, it will directly launch this launch vehicle named-Future Launch Vehicle Type 1, in his opinion , Is too confident and risky.
At the beginning, he led the launch vehicle recovery project, but from the beginning, he carried out many experimental recovery tasks for the missiles he developed.
The rocket is launched to a certain height and then recovered smoothly. In each test, the height is constantly increasing.
When the tested altitude reaches a height of 100 kilometers and it can be recovered smoothly, it means that the recoverable technology of this launch vehicle has reached the standard.
However, the Future Technology Group did not take this step. Instead, once the missile was launched, it had to directly launch the launch vehicle, which is simply crazy.
If this matter were put on Musk, it would definitely not be done. After all, there is no certainty, and it will give people a feeling of overconfidence.
Of course, Cai Ruichen is different from Musk. Musk needs to consider the ideas of those investors. Naturally, it is impossible to do so. If it succeeds, it is good to say, if it fails, it will lose the trust of investors.
And he has no investors at all, and no one can influence his decision. At the same time, he trusts in the production of the base, and he is too lazy to carry out those unnecessary tests. Whatever the outside world thinks, it is all right for this matter. Negligible, no impact at all.
Before, Musk also persuaded Cai Ruichen a few words, but Cai Ruichen just let him watch at ease.
Therefore, Musk did not continue to talk about entangled in this issue. He is not a person who cares about it. After all, this is not his company. Whether it succeeds or fails, it does not affect him much.
As for him, the interest of this launch vehicle in front of him can surpass everything.
His current gaze has always been focused on the rocket in front of him. Through the ratio to the surroundings, he can see that the size of this launch vehicle is a bit larger than the Dragon spacecraft.
This seemingly unimportant feature is what he is most concerned about now. The size and aerodynamic shape of the launch vehicle have strict data requirements.
He is now calculating some data information of this launch vehicle in his mind, but since he doesn't know the overall material and weight of the launch vehicle, he can only get a little simple information.
After a simple calculation, Musk couldn't help but nod, because this missile is very reasonable in terms of aerodynamic shape and size.
As long as the engine thrust and fuel can meet the requirements, then this is an off-take launch vehicle.
For this launch, he couldn't help but gain a little more confidence.
At this moment, the command center sounded a countdown to the last ten seconds. When the number was reset to zero, on the augmented reality projection screen, a large amount of water vapor was sprayed out at the position where the launch vehicle was in contact with the ground ~EbookFREE.me.
This is the effect of evaporating a large amount of cold water under the launch platform after the heat from the tail nozzle of the rocket thruster is ejected.
In the water mist, the launch vehicle slowly left the ground first, and the tail nozzle emitted a small blue flame, but it was this small blue flame that quickly pushed the entire launch vehicle off the ground. .
Seven seconds after launch, the speed of the launch vehicle has broken through the speed of sound at high speed, and the speed is still climbing rapidly, and during the whole process, the flight effect is very stable. Direction, and then use the traction of the earth's gravity to achieve the purpose of gravitational acceleration.
At this moment, the earth is just like a long spring wire, pulling the launch vehicle continuously, which makes the launch vehicle gain the acceleration effect of the planet's gravity in addition to its own power. On the speed buff.
When the rocket completely disappeared from the field of vision of ground personnel, the speed had climbed to the first cosmic speed, and it was approaching at a high speed towards a low-Earth orbit of 200 kilometers.
