摘　　要：针对滑翔飞行器平衡滑翔弹道的工程估算问题,提出高精度平衡滑翔弹道解析计算方法。首先结合平衡滑翔条件,并忽略地球自转相关高阶项及地球摄动,对滑翔飞行器的弹道方程进行简化。然后在满足工程计算精度的假设条件下,先后给出了平衡滑翔弹道的高度、弹道倾角与航程的解析计算方法,能够实现更高精度的估计。Aiming at the engineering estimation problem of the equilibrium glide trajectory of a glide vehicle,a high-precision analytical calculation method of the equilibrium glide trajectory is proposed.Firstly,the ballistic equation of the glide vehicle is simplified by combining the conditions of equilibrium glide,ignoring the high-order terms related to the rotation of the earth and the earth’s perturbation.Then,under the assumption of engineering calculation accuracy,the analytical calculation method of the height,flight path angle and range of the equilibrium glide trajectory are given successively,which can realize higher accuracy of estimation.
