Thermal protection material for space plane (ablator)
A spacecraft orbiting the earth travels at a speed of 8 km per second, and the kinetic energy of the spacecraft is tremendously high. As the spacecraft returns to Earth, the kinetic energy is converted to thermal energy, which causes the surface temperature of the spacecraft to increase dramatically. If no measures are taken to protect the spacecraft surface, the spacecraft will burn up quickly.
Therefore, we are researching ultra-lightweight thermal protection materials for the safe return of spacecraft to Earth, or an experimental vehicle that can actually enter the atmosphere.
