A simplified calculative method for thermal protection of SCAT nosetip

Simplified analysis for thermal protection of the self-contatined Adaptive Transpiration (SCAT) nosetip is provided and the simplified calculation formulas of thermal protection are deduced. The calculation examples of thallium, indium, tin and water coolants are given. The deduced formulae in this paper are simple and convenient. An engineering calculation method of nosetip thermal protection design is obtained in this paper. It can be used in prediction before the ground simulation experiment.
