The reason why Yang Jie chose the liquid oxygen methane engine as the technical route of Huaxing Rocket Launch Company in the next few decades is naturally because the liquid oxygen methane rocket is the most in line with the requirements of repeated use.

After all, most of the cost of disposable rockets is not fuel, and the rocket body, including engines, storage tanks, navigation guidance and control systems, can only be reused to revolutionize the cost of space launches.

Huaxing Rocket Launch Company has successfully realized the primary and secondary recycling of reusable rockets in recent years, which has really reduced the launch cost and once again led to the return of the reuse boom.

The technical team led by Ban Zhinong has made a lot of efforts in rocket engine recovery technology, carbon deposition removal after recycling, and equipment testing, and the company has many launch tasks, and now the technical experience in this area has also been accumulated.

Although Huaxing Rocket Launch Company has failed many times in recycling technology, and has even been ridiculed by many domestic and foreign media or peers, the team led by Ban Zhinong has continuously improved its technology and means, and now it has succeeded more and more, and no one has laughed at the recycling technology of the technical team anymore.

Now that the technical team has even succeeded in recovering the fairing, many companies that develop rockets have begun to sit still, and have announced that they have also begun to develop rockets that can be recycled.

The liquid oxygen kerosene engine developed by Huaxing Rocket Launch Company and jointly developed by Damao can now be reused at least five times after recycling and treatment, so that the cost of rocket launch is also greatly reduced.

In this regard, Ban Zhinong's technical team has now done a very good job, and has accumulated a lot of technical experience.

Moreover, the production of fairings is also a constraint on the production efficiency of rockets, and the cost of fairings is also very expensive, so the successful recovery of fairings allows Huaxing Rocket Launch Company to reduce launch costs and further shorten the rocket launch cycle.

Now Huaxing Rocket Launch Company can basically recycle a lot of valuable parts after the rocket is launched for processing and reuse, which has become a very obvious technical advantage of the company.

Yang Jie is very satisfied with this, after all, Huaxing Rocket Launch Company has done something that those old rocket companies have not done since it was a team with a weak technical foundation, which can be said to be very remarkable.

In the research and development of rocket design, manufacturing, production and rocket recovery technology, the technical team led by Ban Zhinong can be said to have fully exerted their own wisdom and continuous technological innovation, and even developed several black technologies.

The technical team in Huaxing Rocket Launch Company will immediately realize any good ideas, and all aspects can keep up and constantly carry out technical changes.

And this strong atmosphere of technological innovation has also attracted a large number of top talents with very innovative thinking at home and abroad to join this technical team.

"Yang Shao, Dr. Liu Ming recently proposed an upper-stage technical scheme that can run in orbit for a long time, and I think it is very thoughtful. ”

Ban Zhinong said to Yang Jie at this time.

"Well, let's hear about it. ”

Yang Jie opened his mouth and said.

Ban Zhinong smiled and said to a young man in his thirties wearing glasses opposite: "Liu Ming, tell me what you think." ”

This Dr. Liu Ming stood up a little excitedly, because he was so excited that the chair he was making was bounced away by him, making a loud noise.

At this time, everyone looked at him, and Liu Ming hurriedly pulled the chair back, with an embarrassed look on his face.

"Don't be nervous, just tell us what you think. ”

Yang Jie opened his mouth and said.

"Thank you, Mr. Yang......"

Liu Ming also took a breath at this time, sorted out his thoughts, and then said: "My idea is this, can we design multiple upper stages that can be reused for a long time, so that we don't need to design super-large rockets, we only need to launch the payload into the low orbit, by rendezvous and docking with the upper stage above the low orbit, and then send the load to different orbits by controlling the upper stage, and these upper stages can achieve long-term missions for months or even years by refueling......"

Yang Jie also nodded after hearing this idea, this kind of upper stage that can be refueled is very thoughtful, and putting several upper stages in different orbital positions can indeed make Huaxing Rocket Launch Company have a more powerful space carrying capacity.

However, it is very difficult to develop such a high-energy stage of the upper stage, after all, the upper stage has to work in the extremely harsh environment of space for a long time, which is very difficult for the thermal control design of the upper stage, especially to overcome the accurate rendezvous and docking in space, and the fuel filling technology in space, which is not less difficult than the upper stage of the technical route of Eagle Sauce to build a high-performance liquid oxygen and liquid hydrogen engine like a centaur.

Yang Jie thought about it and said to Ban Zhinong: "Dr. Liu's idea is very good, you can start this project first." ”

Hearing Yang Jie's words, Ban Zhinong and Liu Ming both showed joy in their eyes.

"In addition, many of our experiments over the years have been done in space, the cost is still too high, next year I plan to build a large-scale space environment ground simulation device in Qiongzhou Province, for simulating the extreme environment of space, many of our scientific research will not need to be done in the sky, can be completed on the ground. ”

Yang Jie opened his mouth and said.

"Ah, that's great!"

Ban Zhinong said pleasantly: "With such an experimental platform, many of our products and equipment can be completed on the ground, which can greatly shorten our research and development time." ”

There is no such space environment simulation facility in China, and many research and development projects of Huaxing Technology Group in aerospace are to be sent to space with rockets to do, and the cost is very expensive.

Now Huaxing Technology Group has more and more research and development in the aerospace field, and a lot of research and development costs are wasted on rocket launches.

With such an experimental facility, the harsh environment of space can be simulated, and even the lunar environment and Martian environment can be simulated, and relevant scientific research can be carried out in this environment.

Huaxing Technology Group Co., Ltd. developed related aerospace products can be completed on the ground in the space environment in a variety of test verification, can quickly get the test data results, no longer have to wait for the rocket to be launched into space for various test verification, after all, the rocket launch is tens of millions of dollars, and it has to wait for the right launch time.

Yang Jie is a personality who wants to do whatever he thinks, so this time he also wants to put this device in Qiongzhou Province.
