What are the new research directions of China scientists at this year's China Aerospace Congress?

China Aerospace Congress is a comprehensive industry event jointly sponsored by China Aerospace Society and China Aerospace Foundation, and has been selected as an important academic conference guide of China Association for Science and Technology for two consecutive years. ?

This year's China Aerospace Congress raised many scientific and technological issues in the aerospace field in 2020. These problems are solved by experts and scholars from the Academic Committee of China Aerospace Congress. Facing 2050 will play a guiding role in the development of space technology; Play a key role in aerospace technology or industrial innovation; It represents the focus and point of space technology development. As an important standard, it was reviewed and finalized. ?

Its research direction is mostly high-tech in modern aerospace, and the easy-to-understand technologies are listed as follows:

1. Nuclear-powered spacecraft and its engineering application?

Modern rockets are still launched with fuel, and when they are in space, their main energy sources are solar energy and fuel. Nuclear energy has advantages in volume and released energy measurement. Therefore, the application of nuclear power in the space field provides new possibilities for more experiments and long-distance travel in space.

2. Core technologies for clearing space debris

In fact, the outer surface of the blue planet is not what it used to be. It is surrounded by a large number of satellites. In addition, there are all kinds of space junk, as well as debris left by space flight and garbage that can no longer work. As the space around the earth is getting more and more tense, cleaning up the space has become an important issue.

3. Reusable thermal protection materials and life prediction for aerospace vehicles?

According to theoretical calculation, it costs 10 thousand dollars to launch a kilogram of objects into space, and its high price can be quadrant. So how long it can be reused has become the direction that must be studied, which puts forward new requirements for materials science, not only can it be shot out, but also can be recycled!
