Multi-Stage Liquid Propellant Launch Vehicle Conceptual Design, Based on Combinatorial Optimization of Major Design Parameters

The principle goal ofthis paper is developing ofLaunch Vehicle Conceptual Design (LVCD) method based on combinational optimization of major design parameters. To this end, len sub-algorithms will be presented in this design approach. Mass distribution of different stages to launch maximum payload mass to the orbit, pitch program trajectory to get to the maximum final velocity, and providing minimum velocity loss due to gravity. and also minimum axial acceleration ofvarious stages of launch vehicle will be optimized as the results ofthe presented approach. The optimization process is performed subject to the restrictions. Also, the performance index is optimized in a mutual iteration mechanism. Evaluation and verification of the presented method is performed using available data a/two and three-stage launch vehicles.
