摘　　要：为解决火箭基组合动力飞行器上升段飞行过程中飞行走廊规划的问题,提出一种基于马赫数-高度参考曲线的走廊规划方法。针对飞行器的飞行任务及飞行过程中的多约束问题,建立基于二分法求解迎角实现走廊规划的算法流程,选择马赫数-高度曲线作为走廊剖面,依据二分法求解迎角最大值最小值的思路,对马赫数和迎角二分求解,并对规划方法进行了仿真分析。仿真结果表明,该方法能够在满足各种约束的情况下求解出合理的走廊剖面。To solve the problem of flight corridor planning of ascent for RBCC,a method of corridor planning based on the reference curve of Mach-height was proposed.Aiming at flight mission of the aircraft and multi-constraint problem during the flight,puts forward the corridor programming based on the reference curve of Mach-height,and establishes the algorithm flow of corridor programming based on dichotomy to solve the attack angle.Select Mach-height curve as the corridor profile,according to the idea of solving maximum and minimum of attack angle by dichotomy,solve the Mach and attack angle dichotomy.Carry out simulation analysis by planning method.The simulation results show that the method can solve the reasonable corridor section under various constraints.
