摘　　要：回顾了Weissman图的产生及发展历程,对高速再入航天飞行器的横航向气动特性进行了综合分析,指出了引入Weissman图分析方法的必要性。通过对横航向小扰动方程的讨论给出了中国航天领域常用机体坐标系下的CnβDYN和LCDP的表达式,并对一种典型高速再入航天飞行器气动布局进行了全面的横航向特性分析,指出了Weissman图分析的重要意义。The derivation and development of Weissman chart was reviewed in this paper. The Lateral-Directional characteristic of High-Speed reentry vehicle was discussed and the importance of introducing Weissman chart to aerodynamic configuration design was indicated. The form of CnβDYN and LCDP under domestic astronautics body-axis coordinate system was deduced in this paper, and the Lateral-Directional characteristic of a typical reentry vehicle was fully discussed.
