Abstract
Space propulsion systems play an increasingly important role in planning of space missions The traditional method for design of space propulsion systems includes numerous design loops which does not guarantee to reach the best optimal solution Multidisciplinary Design Optimization MDO is an approach for the design of complex systems that considers a design environment with multiple disciplines The aims of this study are to implement and compare Multidisciplinary Feasible and Collaborative Optimization architectures for the multiObjective optimization of a bipropellant space propulsion system design Several disciplines such as thrust chamber cooling and structure were exploited in a proper combination The main optimization objectives in the MDO frameworks were to minimize the total wet mass and maximize the total impulse by considering several constraints Furthermore Genetic Algorithm and Sequential Quadratic Programming are employed as the systemlevel and locallevel optimizers The presented design methodology provides an interesting decision making approach to select the best system parameters of space propulsion systems under conflicting goals
