中文摘要：

开展了飞行器气动与隐身综合特性数值研究，编制了相应的计算与分析程序。该程序的主要功能包括：飞行器外形参数化和计算网格的生成，气动特性计算（利用有限体积方法求解NS方程），隐身特性计算（利用时域有限差分方法求解Maxwell方程），飞行器气动与隐身综合特性分析。作为应用的一个实例，对一种带翼钝锥体的气动和隐身综合特性进行了分析，并设计出两种新的外形，新外形的气动和隐身综合特性与原形相比有明显提高。

英文摘要：

The aerodynamics and stealth performance of hypervelocity aeroeraft were researched using numerical method and the corresponding computing and analyzing program was implemented. This program includes four main parts： Gathering the parameters of the aerocraft outer shape and generating computing grids; Calculating the aerodynamics performance by numerically solving the N-S equations; Calculating the stealth performance using finite difference time domain method ; Analyzing the syntheti- cally performance of aerodynamics and stealth. To test our method, the aerodynamics and stealth performances of a blunt cone with three wings was calculated and analyzed, and two new profiles were designed. The results showed that the aerodynamics and stealth performances have been improved significantly.
