A concept of the terminal descent control algorithm at reentry into the earth atmosphere with near-parabolic velocity

Abstract

A concept of the terminal descent control algorithm of the descent module at reentry into the Earth atmosphere with near-parabolic velocity is proposed. Trajectories with one and two (skip reentry) reentries are considered. Simultaneously, downrange and crossrange misses are eliminated by controlling the bank angle and time of bank angle reversal at each phase of the trajectory. The designed control meets the specified load factor constraint.
