Chang'e-6's Mach 31 is the least worth bragging about, and the black technology behind him is even more invincible than this.
First, it is precision guidance and automatic control, this is our "Fifth Academy of Aerospace", independently developed system, called "GNC system", he is composed of guidance (Guidance), navigation (Navigation) and control (Control) 3 parts, it can be said that without him, Chang'e-6 will not be able to complete the precise landing, and this system, basically the state of automatic driving, only some special circumstances need people to intervene, he is in the entire mission of Chang'e-6, Chang'e-6 is controlled by him in terms of attitude adjustment, orbit correction and flight control.
Second, it is the matter of returning to the earth, this technology has actually been applied to our intercontinental missiles before, and this is already a very mature technology for us, otherwise it would not be broadcast live around the world, because there is no fear of accidents.
Third, black barrier communication technology, this is a key point! What do you mean? Because when the spacecraft enters the atmosphere at high speed, the spacecraft and the atmosphere will have violent friction, and the materials on the surface of the spacecraft will be decomposed and ionized, which will form a plasma shell that wraps the spacecraft, which can absorb and reflect electromagnetic waves, and the spacecraft will not be able to communicate with the outside world.
However, we at the Shanghai Research Institute of the Chinese Academy of Sciences have invented a special material that can maintain communication with the outside world in the midst of black obstacles, which is something that only we can grasp in the world.
Fourth, it is the heat insulation technology, more than 3,000 degrees outside, and the inside has been maintained at a constant temperature of more than 20 degrees, but this is definitely not comparable to the old beauty, after all, people's have passed through the atmosphere and nothing has happened, and the outside is still shiny and bright, hahaha! Funny!
The above technologies are basically our only one, you can use these four technologies to ask Lao Mei, and if you don't know what to ask, then it will be clear at a glance how he landed on the moon!
