摘　　要：为了验证牛顿流理论的效度,在高超声速高温气体效应下设计验证模型,对比牛顿流理论解析解和数值模拟结果,证明牛顿流理论在高温气体效应下仍然具有相当高的效度。研究表明完全气体模式下的牛顿理论仍然可以移植到高温气体情形下,在高温气体效应下为飞行器设计提供前期的概念指导。In order to verify the efficiency of Newtonian theory,an model considering high temperature gas dynamics effect of hypersonic is designed to analysis the results of Newtonian theory and numerical simulation. The results showed that Newtonian theory of complete gas mode also has fairly high validity in high temperature gas,which can provide guidance for aircraft design.
