| Abstract: | This paper develops the optimal control formulation for multi-burn propellant-optimal vacuum flight trajectory.An alternative simple method for handling the inner constraints and transversality conditions has been developed.A more effective and stable numerical method has been employed to solve the problem.Two typical applications have been given to validate the superiority of multi-burn flight in propellant assumption compared with single-burn and impulsive flight. |
