| Abstract: | Simplified analysis for interior flow of transpiration cooled nosetip is provided and the simplified calculation formulas of internal flow parameter are deduced. The calculation examples for T1, In, Sn, H2O coolants are given. The deduced formulas 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. |
