Chapter 754 Rocket Recovery Technology

When the Future Launch Vehicle Type 1 reaches a height of about 100 kilometers above the earth's surface, it has completely escaped the influence of gravity.

Reaching the speed of the first universe, when the object obtains the horizontal speed movement in this direction, it can realize the movement around the earth without increasing the power.

However, the launch vehicle continued to move toward higher space, but the speed no longer increased.

In the ground command center, after the launch vehicle successfully escaped the gravity of the earth, there was no cheering as expected.

Everyone still stayed quietly at their posts, watching the launch vehicle that was moving away from the earth step by step.

At a distance of one thousand kilometers from the earth, the fairing on the head of the launch vehicle broke away from the launch vehicle, and the space capsule officially separated from the launch vehicle. After the separation, one of the two objects continued to fly forward, and the other was towards the earth. Fall back vertically.

The two opposite-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 hatch of the future space capsule is opened, and a satellite weighing only about 100 kilograms is separated from the space capsule, and is pulled away from the position of the space capsule by the gravity of the earth. Afterwards, two solar panels are deployed, and the satellite begins to Work.

At this time, the power system of the future space capsule will continue to increase its power and fly towards a height farther away from the ground.

On the ground, after the command center watched the image of releasing the satellite from the space capsule, Musk looked surprised.

Originally, he just thought that the three satellites carried in this launch were only released in the first orbit or adjacent orbits at once.

But I didn't expect that it would be more difficult to release satellites separately in multiple orbits. This technology is a new threshold for launch vehicle launch technology.

In particular, the design requirements for space capsules have become very demanding. There are not many countries in the world that can independently research and design such space capsules.

This was Musk's first surprise. The other surprise was that the launch vehicle that was returning to the earth actually came towards the launch center.

This made him feel once again that Cai Ruichen was playing too big.

Launch vehicle recovery technology is not a simple technology, and it has extremely high risks.

In his opinion, it is the best choice for the rocket to land on the sea. After all, even if there is an accident on the sea, it will not hurt personnel and facilities.

And this kind of technology is relatively simple. It only needs to reserve a certain amount of fuel on the launch vehicle, so that the launch vehicle can fall freely after the space capsule is released, and arrange to meet the launch vehicle on the sea where the landing point has been calculated. Landed flat boats will do.

But the Future Technology Group obviously did not do this, because the launch vehicle during the return process has been resting its own orbit, and the target is directly aimed at the launch vehicle recovery platform in the launch center.

Seeing that the launch vehicle is constantly resting its orbit on the way back to Earth, Musk's original thoughts of pride were 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 bottom of the rocket to choose to land.

Instead, after the rocket falls freely, under uncontrollable circumstances, the landing point is calculated in advance, and then the ship is arranged to go to prepare in advance.

After re-entering the atmosphere, the engines on the Dragon spacecraft will start to run with the support of the reserved fuel.

Reduce the falling speed of the carrier rocket, and at the same time adjust the falling attitude of the carrier rocket so that it slowly lands toward the position facing the ship on the sea surface.

Compared with such technology, Future Technology Group also needs to prepare a large flat ship capable of recovering launch vehicles in the Arabian Sea.

But obviously, the launch vehicle of the Future Technology Group looks more advanced, at least it does not need to land on an unstable sea vessel, 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 towards the northern desert.

As the height of the launch vehicle fell rapidly, everyone in the command center couldn't help holding their breath.

The successful launch of the rocket is not exciting enough for every staff and engineer here, because it is only the first step to success.

But the most critical rocket recovery is the most critical last step of this rocket test launch. Whether this launch can be completed perfectly depends on whether it can land on the recovery platform stably.

The carrier rocket that quickly fell towards the satellite launch center, when it was less than 10,000 meters away from the ground, the engine at the tail nozzle accelerated.

The falling speed of the launch vehicle was slowing down again, and when the launch vehicle accurately landed on the recovery platform, the speed had dropped to an extremely low level.

The flame from the tail nozzle will be sprayed on the ground. There is no dust and dust around the prepared recovery platform. On the hard alloy platform, almost everyone has forgotten to breathe, watching the launch vehicle slowly land 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 approach the ground a little bit, and finally land on the platform smoothly and vertically like a helicopter , at the moment when the landing was stable, the engine of the launch vehicle just stopped working.

When the launch vehicle landed steadily on the recovery platform, everyone in the entire command center cheered uncontrollably.

Future Media Company also broadcast this historic scene live 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 whole of Iraq excited. Cheers.

Such a picture also made many people excited. Of course, many people thought it might 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 the recovery of the launch vehicle of the Future Technology Group this time is absolutely different in meaning. It can even be said that this kind of recovery is the real recovery technology of the launch vehicle.

Compared with the recovery method of American space exploration technology, it is more efficient and complete. It seems to be the same, but it is actually quite different.
