Abstract : The article considers the variational problem of the optimum motion in a gravitational field (the useful-load maximum) with an engine system of limited power in conjunction with an energy accumulator and an engine of limited exhaust velocity. The general properties are determined for optimum motion exhibiting the indicated limitations. It is demonstrated that an optimum trajectory may be made up of those segments of motion with optimum variations in exhaust velocity, the intervals at which the exhaust velocity is equal to its limit value, as well as of passive segments.
