本文着重研究了航天飞机尾部设计装置飞行特性的测定方法,并通过 (STS)飞行试验前五次测出的底部阻力特性与风洞试验结果的可比性,从而得到了确定底部阻力的基础。文中以轨道返回阶段的压力传感器为测量手段,分别得到了底部压力曲线、典型分析数据、底部阻力系数等。本文旨在从理论与实践的结合上,给出航天飞机空气动力特性的底部阻力确定的依据。
This paper focuses on the determination of the flight characteristics of the aft tail design of the space shuttle and obtains the basis for determining the bottom resistance by comparing the bottom resistance characteristics measured by the STS flight test with the wind tunnel test results five times. In this paper, the pressure sensor at the orbit return stage is used as the measurement method, and the bottom pressure curve, typical analysis data and bottom resistance coefficient are respectively obtained. The purpose of this paper is to base the combination of theory and practice on the determination of the bottom aerodynamic drag of a space shuttle.
