Method for Parametrically Optimizing a Power-Propulsion Complex for an Orbital Transport System

Abstract

A procedure for solving the problem of design-parameter optimization of the power-propulsion complex of an interorbital transport system on the basis of a reusable tug with electric propulsion power plants by considering the stochastic character of the initial information is presented. The efficiency factor of the power-propulsion complex is the probability of mission success. Conditions of mission success are presented as a set of stochastic inequalities. The problem is formalized, optimizing variables are determined, the relationships for calculating the target function are determined, and the restrictions are examined. It is shown that it is reasonable to consider the adaptive possibilities of the power-propulsion complex of an interorbital transport system under specifying the initial information, and the way for considering them is also presented. How to consider the uniqueness of the implementation stage of structure perfection (specific masses) for a power-propulsion complex’s elements, which are the random values at the early design stage, is examined.
