OPTIMUM STAGE-WEIGHT DISTRIBUTION OF MULTISTAGE ROCKETS

Abstract

In this analysis a generalized method is developed for determining the optimum stage-weight distribution for multistage rockets. Inclusion of the variations in structural factors with stage weights in the optimization process is shown to lead to a more generalized set of optimum conditions. Expression of all rocket weight parameters in terms of the stage weights allows for convenient optimization as well as for a comparison with previous optimization methods. This approach permits improved optimum design over existing methods for maximizing payload ratios for given ranges and for maximizing ranges for given payload ratios. An evaluation of previous methods is included for comparison purposes, and the limitations of these previous methods are discussed.
