Abstract

Abstract: Abstract： The entry flight envelope of orbital reentry vehicle is divided into three phases: the atmospheric entry, terminal area energy management (TAEM) and autolanding. In this paper, a flight range and vertical profile optimization algorithm are developed for the terminal area energy management phase. Through the propagation of the dynamic equation from different initial states, by maximizing the control margin of speed brake, a range which is most fit for the aerodynamic characteristic of the vehicle is generated, and the best heightdynamic profile in correspondence with this range is designed simultaneously. The 6DOF simulations under various initial states deviation and dynamic uncertainties demonstrate that the vertical profile is robust.

Key words: Keywords： orbital reentry, TAEM, range optimization
