Wang Bin naturally understood Elder Qin's worries very well. After all, China had just experienced launch failures and sacrifices in the early stages of developing its space industry. Therefore, Elder Qin and others did not want the tragedy to happen again on the side of Pass Technology. After all, Even if Tiangong Science and Technology Aerospace Company is a private enterprise, it is still a Huaxia Aerospace Company and a part of China's aerospace industry. Tiangong's aerospace development is actually the development of China's aerospace industry.

Therefore, after thinking about it, Wang Bin finally agreed to Mr. Qin's proposal to go to the South China Sea launch site to launch the Tiangong-2 rocket.

Of course, this launch, like the previous two, is not an empty rocket launch, and will also be equipped with China's official spacecraft, and this time because the Tiangong-2 rocket of Tiangong Technology has a capacity of 5 tons The low-Earth orbit carrying capacity has a prohibitive orbital carrying capacity of about one ton, so the spacecraft carried this time will be very different from the last time.

That is, the spacecraft to be carried this time will be larger in size, and its weight will reach the limit that this rocket can carry, which is about 5 tons. Of course, the manufacturing success or failure of this spacecraft will also be higher , Not to mention the launch cost, the success or failure of just manufacturing this spacecraft is as high as billions.

Moreover, according to Mr. Qin's penetration, if this launch of this rocket can perfectly send the spacecraft into the predetermined orbit, then the next time they launch the spacecraft for the official launch of Tiangong Technology, it will no longer be Instead of launching into low-Earth orbit, spacecraft in medium and high orbits will be launched.

This also made Wang Bin look forward to it very much.

Of course, although the second rocket of Tiangong Technology has been successfully developed at this time, under the rocket of the same weight, the carrying capacity of this rocket of Tiangong Technology is still somewhat low.

Although, among them, the rocket of Tiangong Technology has the function of recycling, so after the launch, a certain amount of fuel must be left so that the rocket can be returned to the earth. If there is no remaining fuel left If it is, then the rocket cannot change its orbit in space at all, so as to recover the rocket.

However, Wang Bin still believes that this rocket still has a lot of room for improvement, so at this time, Tiangong Science and Technology's rocket research and development laboratory is also designing a transformation plan for this rocket to make the rocket's carrying capacity stronger. .

And at this time, Rocket Lab has already achieved certain results. They decided to use the new solid-state fuel technology provided by Wang Bin. In this case, the rocket's carrying capacity will definitely have a lot of room for improvement.

However, for the recovery of solid fuel boosters, there is still a big problem in front of everyone in the laboratory, and there is no good solution yet.

After all, unlike liquid rockets, solid rockets cannot be extinguished after ignition. They can only be extinguished after the solid fuel of the rocket is exhausted. Therefore, it is still very difficult to accurately recover solid fuel rockets, unless Installing another engine on the solid rocket will undoubtedly greatly increase the take-off weight of the rocket, which is absolutely not advisable.

Therefore, for this rocket of Tiangong Technology, after its solid fuel booster is separated from the main body of the rocket, it can only choose to use a parachute for parachuting. After all, after the fuel inside the rocket is exhausted, the solid fuel rocket It's not very heavy, and there is absolutely no problem using a parachute.

It's just that after the booster rocket lands, people still need to search for it. After all, parachuting cannot accurately land on the launch platform and come back. certainly,

There is no problem controlling the booster rocket to land in a general area.

In addition, since the rocket this time is a multi-stage rocket, there are also certain difficulties in the staged recovery of the rocket. Fortunately, their rocket research and development personnel of Tiangong Technology have solved all these problems .

Afterwards, Wang Bin and his Tiangong Technology transported the first completed Tiangong-2 five-ton carrier rocket to the South China Sea launch base by sea, and carried the official spacecraft, and finally succeeded. put the official spacecraft into orbit.

At the same time, the recovery of the rocket was also very successful. Not only was the rocket booster successfully parachuted and landed on the scheduled sea, but the rocket was also successfully recovered in terms of classification, which also made heaven Engineering Technology has greater confidence in the rocket it designed.

It's just that although this rocket has been successful, because it is the first rocket of this rocket, after the successful recovery, this rocket was not ready to be reused, but was transported back to the company by Tiangong Technology. Together with the previous Tianshou Gong-1 rocket, it was put into the aerospace exhibition hall of Tiangong Technology for the employees of Tiangong Technology and future guests to visit.

At the same time, the manufacture of the first Tiangong-2 rocket has also begun, and the diameter of this rocket is slightly smaller than that of the first Tiangong-2 rocket, but it is much longer in length.

At the same time, some optimizations have been made in the structure of the rocket, which will make the rocket's load capacity even larger, reaching about 6 tons, and the technology in rocket recovery is also more mature, which can be achieved More precise recycling.

In addition, in terms of larger rockets, Tiangong Technology has also launched a comprehensive design work, and the rocket designed this time, which is the Tiangong-3 rocket, has a maximum carrying capacity of the earth orbit. It will reach about 10 tons, and the self-weight of the rocket will also reach about 600 tons. It can be said that if this rocket can be designed and launched successfully, this is definitely a milestone for Tiangong Technology.

Therefore, whether it is Wang Bin himself or the technicians at the rocket research and development laboratory, they are all looking forward to the design of the new rocket. Of course, because the rocket is heavier and has a stronger carrying capacity, its technical difficulty is naturally higher. Therefore, the designers in the laboratory are more cautious when designing. Even the design of each part of the rocket has to go through countless calculations before it can be determined, although many calculations are king. What Bin provides is a mature technology.

Of course, in addition to being concerned about new rocket design and development projects, Wang Bin has not relaxed his concern about aero-engines.

Especially for the test flight of No. 9 plane, he basically called Qiu Tuan and the others every day to inquire about the condition of the plane and the engine.

At the same time, their Tiangong Technology has now begun to modify other No. 9 transport planes, and Wang Bin and his Tiangong Technology have basically solved the problems discovered before, such as the previous engine problems, and the No. 9 transport plane itself. skinning problem.
