Chapter 625

Baozixuan knows that what Qian Lao said is very implicit. As an international student with American background, he certainly knows the importance of intellectual property rights for a company. But after all, this is related to the development of the national aerospace industry. I know that some people are difficult, but I still want to have a try.

People like Bao Zixuan can't impress him with money. People don't lack money at all. I'm saying that the country needs funds for development, and I can't get much money. As for patriotism, I don't know what to say. At this time, Xiangjiang has no patriotic education. I just hope to find a breakthrough and see what conditions can satisfy the other party.

Bao Zixuan said with a smile, "I understand what the senior means, but some technologies don't dare to expand outward at present. Batumi has been staring at the black cloud group. It can be said that many things are stretched. If you don't worry about leaking secrets, heiyun group can process parts for domestic satellites. As long as Huaxia gives technical indicators and processing accuracy, the rest can be handed over to us. "

Hearing this, Qian Lao didn't say much. After all, it's difficult for people. Now it's very rare to get such a reply from the other party. At least there are still opportunities for cooperation.

Mr. Qian: "I can't make up my mind to promise you. I'll explain the situation to the above and make a decision. I have seen the ground effect aircraft of heiyun group, which is very shocking. It can be said that at present, heiyun group has reached the world advanced level in the aviation field, and at least the aviation engine is no worse than that of any country. In combination with the overall layout of the enterprise, does heiyun group also want to enter the aerospace field in the future? "

Although Qian is only interested in the aerospace field, he still pays attention to technology companies. China had few exchanges with other countries before, but sometimes we still need to learn from the achievements of other countries in the field of science and technology. Only by learning from each other can we make progress, otherwise the gap will only become larger and larger.

Black cloud group started from games, and then gradually entered the fields of toys, computers, household appliances, chips, CNC machine tools, digital cameras, automobiles and so on. In the past two years, it has entered the fields of military industry and aviation. From the perspective of layout and planning, baozixuan's next step must be to conquer space. The earth can't meet the ambition of the young richest man. Not only does China think so, but many institutions have made such analysis. It can be said that this is an open secret and can't deceive people at all.

Bao Zixuan: "heiyun group does have such a plan. Now the time is not very ripe. At present, the cost of rocket technology is still too high. I did a preview of rocket recovery in college, which is difficult to achieve with the existing technology. If traditional rockets are launched, it will be a waste of resources. How to use rocket recycling technology to make the aerospace industry enter a benign development is what black cloud should consider. "

If ordinary people say they want to develop recyclable rockets, it is definitely a joke. But now it's baozixuan who says that he is not only an engineer, but also a super rich. He has the ability to do anything he wants to do.

Qian Lao: "black cloud wants to directly cross the rocket to develop the space shuttle, which is a great leap in technology. And I heard that the launch cost of the space shuttle is very high, which is not as ideal as expected. "

The space shuttle is a reusable vehicle between low earth orbit and the ground. It can take off vertically like a launch vehicle and land at an airport after returning to the atmosphere like an aircraft. The US space shuttle consists of an orbiter, an outer tank and a solid booster. The Soviet space shuttle itself is not equipped with a main engine, so it is only a spacecraft, not a transporter. It needs to be sent into space by means of the energy carrier rocket.

It was originally planned that the cost of each flight should be US $50 million, but in fact, the cost of each flight is as high as US $500 million. After returning, there will be a lot of time-consuming and laborious maintenance, which makes NASA's financial burden unbearable. Although the original intention of putting forward the space shuttle is to reduce the expenses in the whole process of manned space development and launch, Americans found that this is not the case in the process of implementing this plan.

Although Qian Lao has left the United States for many years, as an authority in the world aerospace field, he can still see some clues from the data. The so-called space shuttle of the United States and the Soviet Union is not so perfect in design, and it is not necessarily the development direction of space industry in the future.

At least not in line with China's national conditions, technology is on the one hand, the most important is that the required funds will bring down the domestic economy. Now I hear that a company in baozixuan wants to do this. Mr. Qian is very worried that the space shuttle will bring disaster to the whole black cloud group.

Bao Zixuan: "even if black cloud enters the space field, it will not develop the space shuttle. At least it will not enter the space shuttle field until the space engine and fuel have made revolutionary innovation."

"What heiyun needs to do is to recycle the rocket, let the first stage rocket land vertically after launch, and realize soft landing with the help of reverse thrust engine. In this way, the first stage rocket can be reused and can be launched many times after maintenance. "

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.
