Description

technical field [0001] The invention relates to a ground simulation experiment device for atomic oxygen oxidation of an ultra-high temperature heat-resistant material. Background technique [0002] The reentry speed of the earth orbiter and other planetary probes, such as the lunar probe, is about the first and second cosmic speeds, and the reentry speed of the intercontinental missile warhead is about 7km / s, and the reentry vehicle has a high initial kinetic energy. At the same time, it is affected by the gravitational field of the earth, and it also has extremely high potential energy. As the altitude drops, this energy is converted into kinetic energy, and the aircraft will have a very high flight speed. Compression causes the temperature to rise rapidly, making the surface temperature of the hypersonic vehicle close to 2000°C; during the actual flight of the vehicle, due to the high-speed flight characteristics, the gas on the surface of the vehicle’s structural material...
