Vol 3 Chapter 754: Rocket recovery technology

When the future launch vehicle Type 1 reaches a height of about 100 kilometers from the surface of the earth, it has completely got rid of the influence of gravity.
When the speed of the first universe is reached, when the object obtains the horizontal velocity movement in this direction, it does not need to increase the power to realize the movement around the earth.
However, the launch vehicle continues to move towards higher space, but the speed has no longer increased.
In the ground command center, after the launch vehicle successfully got rid of the gravity of the earth, there was no cheering as expected.
Everyone stayed quietly at their posts, watching the launch vehicle moving away from the earth step by step.
At a distance of 1,000 kilometers from the earth, the fairing on the head of the launch vehicle separated from the launch vehicle, and the space capsule was formally separated from the launch vehicle. After the separation of the two objects, one continued to fly towards the front and the other towards the earth. Fall back vertically.
The two opposed jet engines ignited almost simultaneously, and the launch vehicle quickly returned to the earth. At the same time, under the acceleration of its own power, the space capsule immediately came to the tenth place of the first satellite.
The first door of the future space capsule was opened. A satellite weighing only about 100 kilograms was separated from the space capsule, and the gravitational pull of the earth moved away from the position of the space capsule. Then the two solar panels were deployed and the satellite started jobs.
At this time, the power system of the future space capsule continues to increase its power and flies toward a height farther away from the ground.
On the ground, Musk looked surprised after watching the release of the satellite from the space capsule in the command center.
Originally, he only thought that the three satellites carried in this launch were only released in the first orbit or adjacent orbits all at once.
But I didn't expect that it would be a more difficult multi-orbit to release satellites separately. Such a technology is a new threshold for launch vehicle technology.
In particular, the design requirements for space capsules have become very demanding. There are few countries in the world that can independently research and design such space capsules.
This was the first unexpected place for Musk. Another thing that made him feel surprised was that the launch vehicle, which was returning to the earth, came towards the launch center.
This made him feel once again that Cai Ruichen was playing a little big.
The launch vehicle recovery technology is not a simple technology, and it is inherently extremely risky.
In his opinion, this rocket landing on the sea is the best choice. After all, even if an accident occurs on the sea, it will not harm personnel and facilities.
And this kind of technology is relatively simple. You only need to reserve a certain amount of fuel on the launch vehicle to let the launch vehicle fall freely after the space capsule is released, and arrange to welcome the launch vehicle on the sea where the landing point is calculated. The landing flat boat will do.
However, the Future Technology Group obviously did not do this, because the carrier rocket during the return process has been restoring its orbit, and the target is directly aimed at the carrier rocket recovery platform in the launch center.
Seeing that the launch vehicle was constantly restoring its orbit as it returned to Earth, Musk had some proud thoughts, but it was completely shattered in an instant.
In fact, the Dragon spacecraft of space exploration technology also has similar capabilities, but it is not used to rest the rockets that choose to land.
Instead, after the rocket landed freely, under uncontrollable circumstances, the landing point was calculated in advance, and then the ship was arranged to go to prepare in advance.
After returning to the atmosphere, the engine on the Dragon spacecraft will start to run with the reserved fuel support, reducing the speed of the launch vehicle’s fall, and at the same time adjusting the launch vehicle’s fall attitude so that it faces the ship on the sea. The position slowly landed.
Compared with this technology, the Future Technology Group also needs to prepare a large flat ship that can recover the launch vehicle in the Arabian Sea.
But obviously, this launch vehicle of Future Technology Group looks more advanced, at least it does not need to land on ships that are not very stable at sea, but relatively speaking, the technical difficulty is naturally higher.
Before the space capsule released the second satellite, the launch vehicle had re-entered the atmosphere, returned to the airspace of Iraq, and landed toward the northern desert.
As the launch vehicle fell rapidly, everyone in the command center couldn't help holding their breath.
The successful launch of a rocket is not enough for every staff and engineer inside, because that is only the first step to success.
But the most critical rocket recovery is the most critical final step of this rocket test launch. Whether this launch can end perfectly depends on whether it can land on the recovery platform stably.
The launch vehicle that fell quickly toward the satellite launch center, when it was less than 10,000 meters from the ground, the engine of the tail nozzle accelerated ~ EbookFREE.me ~ the launch vehicle's falling speed slowed down again When the launch vehicle arrived accurately on the recovery platform, its speed had dropped to an extremely low level.
The flame from the tail nozzle will be sprayed on the ground. There is no dust or dust around the prepared recovery platform. On the hard alloy platform, almost everyone forgot to breathe and watched the launch vehicle descend slowly like a helicopter. .
All the balance wings on the launch vehicle, under the control of the computer, ensure that the launch vehicle is completely perpendicular to the ground at a 90-degree angle, and then a little bit closer to the ground, and finally, like a helicopter, it will land on the platform smoothly and vertically. At the moment when the landing stabilized, the engine of the launch vehicle also stopped operating.
When the launch vehicle landed firmly on the recovery platform, everyone in the entire command center cheered with emotion.
Future Media Company also broadcast this historic scene to audiences all over the world for the first time. From the launch of the rocket to the successful recovery of the launch vehicle to the launch center, such an exciting scene is enough to make the entire Iraqi Cheers.
Many people are passionate about this picture. Of course, there are many people who think it may be nothing. After all, there were successful pictures of rocket recycling and reuse a few years ago.
It’s just that those who understand are very clear that this time the future technology group’s launch vehicle recovery has absolutely different meanings, and it can even be said that such recovery is the real launch vehicle recovery technology.
Compared with the recovery method of American space exploration technology, it is more efficient and complete. It looks the same, but in fact it is quite different.
