Abstract: For studying the thermal distribution on the hypersonic vehicle head in the case of full cover protection, this paper proposes a thermal protection scheme with the active film cooling based on micro jet, and an optimization of the distribution of the film holes. By solving the Navier-Stokes equations, the hypersonic stagnation pressure and the surface temperature distribution of the vehicle front are obtained. It is shown that the temperature at the wall of the hypersonic vehicle could be below 1000 K under the active thermal protection. This scheme provides a new idea for the future hypersonic vehicle design.
