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.
