In this paper，a design method for the 3-degree standard return trajectory of the manned spaceship is studied. The basic design concept is to first set up the motion equations of it's return trajectory in the return coordinate system，then to homogenize the reentry overload and diminish the flight range difference between the standard trajectory and the self-spin one when the lift is out of control by using non-constant bank angleγ_ν(t). The lateral guidance idea is introduced to determine the sign of γ_ν(t). Finally，the theoretical analysis and numerical results show that the design scheme proposed has good practical value.
