This memorandum presents the results to date of a study of the problem of re-entry into the earths atmosphere, by a vehicle returning from a space flight mission. Various re-entry conditions are studied using aerodynamic lift for deceleration and range control. Particular attention is given to cases where re-entry velocity is equal to escape velocity. The report shows that for non-lifting trajectories with re-entry velocity of 11,000 ms approximately escape velocity only 0.4 degree variation in re-entry path angle is allowable if peak deceleration is to be held less than 10 gs. Range from re-entry to impact is shown to be variable up to 10,000 km for re-entry with escape velocity. Author
