The drag force is obtained by calculation of the momentum deficit in the wall boundary layer.
拖曳力,得到了计算的势头赤字在墙上的边界层。

Using numerical calculation, optimal roll program, the ratio of lift and drag, reentry Angle and reentry time of spacecraft are gotten.
通过数字计算,得到飞船的最优滚转程序、升阻比、再入角和再入终端时间。

The calculation results prove that unless the initial film thickness or the relative velocity is very large, the inner evaporation drag should be taken into account at high temperature conditions.
