Aero-Heating Analysis for Hypersonic Blunt-Headed Body

Lü Hongqing,Wang Zhenqing,Wang Yongjun,Zhang Cuie,Jin Chengbin(Department of Space Engineering,Harbin Engineering University,Harbin,150001)  
Taking hypersonic reentry body as an example,the boundary-layer edge parameters are determined by solving Euler equations.The heating flux density of warhead at zero attack angle is calculated by using reference enthalpy method basing on theory and semi-empirical,and the heat proof effect of blunt leading edge is proved by the temperature curve.Based on this,the temperature field along thickness for stagnation region is analyzed by using finite-element method,which provides a reference for heat proof design of the heat protectetion design of reentry body.
