大气密度分层计算时的再入弹道解析解

给出了在考虑阻力系数为速度的函数的情况下，并将大气密度进行分层计算时，估算再入飞行器弹道主要参数的一组解析式。按上述方法进行了仿真计算，并将计算结果，Ｂａｒｂｅｒａ解，有关文献解同数值解进行了比较。结果表明，由于大气密度采用分层计算，更真实地反映了飞行器的再入环境、解析估算值较其它两种解更接近于数值解，完全可用于再入飞行器的再入弹道初步估计和再入性能分析。

Resolution Value of Reentry Vehicle Trajectory under Atmosphere-Density-Delamination

A set of resolution formulas of the mostly trajectory parameters of reentry vehicle is provided, on condition that the resistance coefficient is a function of velocity and delamination is used in calculating atmosphere density. Compared with Barbera algorithm and that of the second literature referring to numericalcal culation values, it reflects the reentry environments of vehicle relatively truly and it's values are furthermore close to the numerical calculation values,because of calculating atmosphere density by delamination in this letter, and so it can be applied to calculating trajectory of reentry vehicle approximately and making analysis on reentry performance.
