Chapter 625 (2/2)

It can be said that the technology proposed by Bao Zixuan is a proper black technology in this era. Qian must have thought about these problems before he was old; But I still feel it is difficult to break through the technical bottleneck.

Qian: ”do you know what technical problems need to be solved to make the first stage rocket soft landing! This is a complex project. Once the direction is not determined, the ground personnel will suffer heavy losses. ”

Fortunately, baozixuan has made preparations in advance, otherwise he has no right to speak in front of academic leaders.

Bao Zixuan: ”first of all, we should control the attitude of the rocket; Because the shape of the rocket is slender, the landing posture is not correct, and it is easy to fall down. ”

”Secondly, in addition to being reusable, the rocket engine also has the characteristics of adjustable thrust.”

”At the same time, the arrow body should adopt new composite materials to further reduce the weight under the condition of ensuring high strength.”

”Finally, in view of the” lessons ”of the space shuttle, the reusable rocket can meet the re launch requirements only after simple detection and maintenance after recovery.”

”In other words, we need to develop directional gyroscopes with higher accuracy to ensure that the flight attitude is balanced. Not only the hardware should be improved, but also the software of the flight control system should be improved. Qian thought it was very feasible to hear the technical difficulties and solutions given by Bao Zixuan. At least there is no problem in theory. Maybe it is really a direction of future development.

The initial investment will certainly increase. Once developed, it will definitely reduce the rocket launch cost to one-third or even lower. It is really feasible for black cloud group to enter the rocket field with this idea, but the other party is a private company after all, and always feels a little awkward.

Mr. Qian: ”it's very feasible in theory, but there are many problems to be solved in the early stage. This requires huge capital investment, and there is no guarantee of success. Aerospace is the most expensive industry; Although Americans landed on the moon, they also spent hundreds of billions of dollars. ”

”Although it is of great benefit to the future, there is no benefit at all in a short time. Black cloud is just a company and needs careful consideration in terms of capital. ”

It can be said that Qian Lao made a kind reminder only out of kindness. As the top experts in the aerospace field, of course, we know how much R & D investment will cost. Huaxia is still very hard to work as a country. It will be more difficult for a company of heiyun group to enter the aerospace field.

Bao Zixuan: ”I know this road is very difficult, but someone must go ahead first. If you're not modest, you can't spend all the money black cloud earns in 10 lifetimes. You always have to do something different to make life meaningful. ”

Old Qian thought that baozixuan was not only a rich man, but also a young super rich man. As long as it's what he wants to do, R & D investment is nothing at all. Maybe he can really succeed in the R & D of recyclable rockets.

Then the two men discussed some technical problems until Mrs. Qian told them to eat.
