Abstract: An algorithm for separation time T a of manned spacecraft reentry capsule from escape system is discussed.At first,an approximate solution of escape trajectory is deduced.Then,a real-time algorithm for separation time T a is presented,which is based on the approximate solution.Finally this simple algorithm is proved to be useful for increasing the probability of success of emergency rescue by numerical simulation.
