20~85 km大气密度与风场对再入飞行器的安全及返回(即飞行器可控可达)有非常重要影响。分析了高空大气参数变化影响因素,基于CIRA-86大气模型与美国航天飞机飞行实测数据,分析了大气密度偏差范围;基于国外实测文献数据及等概率分布椭圆模型,给出了风矢量剖面,研究了风矢量剖面在飞行器设计中的应用。
20 ~ 85 km Atmospheric density and wind field have a very important influence on the safety and return of reentry vehicles (that is, the controllability of the aircraft). Based on the CIRA-86 atmospheric model and the measured data of the U.S. space shuttle, the deviation range of the atmospheric density is analyzed. Based on the measured data in foreign countries and the elliptic model with the same probability distribution, the wind vector cross-section is given. Application of wind vector profile in aircraft design.
