Trajectory analyses for space missions are often based on impulsive approximation in which finite-thrust powered phases of finite duration are replaced by instantaneous changes of velocity; investigation has been carried out by use of perturbation methods that enable optimal impulsive trajectory to be compared with corresponding finite-thrust trajectories for same mission; analysis is limited to in-space maneuvers (orbit transfers); simple, convenient formulas are presented for estimating performance penalty (extra characteristic velocity requirements) resulting from use of finite thrust.
