摘要
本文介绍了球冠倒锥形返回舱的外形母线方程、特征点参数和气动性能。用修正牛顿理论对返回舱的气动系数进行了计算预测并与现有的实验数据作了比较。对现有的阿波罗、双子星座和联盟号三种小升阻比返回舱的气动系数进行了给定、分析和评述。
This paper introduces the equations in generating curve,the parameters of characteristic points.and the aorodynamic coefficients of the spherical segment-reversing cone modules of re-entry vehicles.Comparisons have been made between the predicted curyes of modified Newtonian theory and ayailable experimental data of aerodynamic coefficients for the spherical segment-reversing cone modules of re-entry vehicles.The aerod ynam ic characteristics of three type modules,Apollo,Gemini,and Soyuz,have been prescribed,analyzed and eyaluated.
