Abstract

Abstract This paper presents the approximate analytical solutions on velocity, altitude, range, deceleration, maximum deceleration, time rate and maximum time rate of average and local stagnation region heat transferred into vehicle, total heat transferred into vehicle and time of flight for boost glide or orbital re-entry into planetary atmosphere for various kinds of re-entry trajectories. These trajectories include (1) Great circle flight at small angles of inclination, (2) Great circle flight at large angles of inclination, (3) Minor circle flight at small angles of inclination, (4) Minor circle flight at large angles of inclination, (5) Constant equilibrium temperature flight, (6) Constant deceleration flight, (7) Constant aerodynamic load factor flight, (8) Constant rate of descent flight, (9) Constant angle of inclination flight, and (10) Constant rate of heat input flight.
