1.In this paper, 11 species Air Model is used for calculating the chemical non equilibrium viscous shock layer flow over hyperboloids. The stagnation streamline distributions of pressure、temperature and N + 2、O + 2、N +、O +、NO + and e - number density are given and compared with the results of 7 species、5 species models.
本文采用11组元化学模型对双曲体粘性激波层化学非平衡绕流流场进行了数值计算，给出了压力、温度，N＋2、O＋2、N＋、O＋和NO＋摩尔浓度及e－数密度在驻点的分布，并与7组元、5组元的计算结果作了比较。收藏指正
2.The third scheme,whose streamline frontal shape is shuttle shape,with lowest air pressure pulse and aerodynamic drag,was selected as the optimization scheme.
