Abstract

The purpose of this article is the CONCEPTUAL DESIGN of a two-stage crew launch vehicle with side boosters. At first, in order to achieve a suitable design point, the STATISTICAL DESIGN technique is used, and then STATISTICAL DESIGN process is validated by using two degree of freedom simulation and doing energetic-mass calculations. Then, MULTIDISCIPLINARY DESIGN OPTIMIZATION approach is applied for initial CONCEPTUAL DESIGN optimization. The preferred structure for MULTIDISCIPLINARY DESIGN OPTIMIZATION is all-at-once and GENETIC ALGORITHM (GA) is used as the optimizer algorithm. In order to achieve more accuracy, SIMPLEX METHOD is employed using GA’s results as a combined algorithm. Having performed the optimization process, a mass decrease of about 4 tons from missile gross weight was attained with respect to normal simulation results, and as already known, the decrease in gross mass undeniably leads to a consequent decrease in the cost of producing and launching missiles.
