有升力时的再入弹道解析解

Approximitive Solution of the Ballistic Missile's Reentry Trajectory

建立了导弹再入段运动方程的简化式,利用空气阻力、升力及飞行迎角的拟合式,对简化的运动方程进行了近似计算,推导出了飞行速度、迎角、弹道倾角及射程关于飞行高度的表达式。仿真结果表明,该计算方法是可行的。

The simplified formula of a reentry movement equation is established, the equation is calculated approximately by using the fitting expression of aerodynamic resistance, climbing force and angle of attack. The expression of velocity, angle of attack, ballistic obliquity and range along with altitudes is presented. The result of simulation shows that the mathematical model is feasible.
