Sensitivity Analysis on Weight and Trajectory Optimization Results for Multistage Guided Missile

Addressed here deals with the problem of weight and trajectory optimization for multi staged anti-air missile. By using the subsystem requirements, such as aerodynamic coefficients, thrust and structure, amount of propellant and weight of each stage can be optimized via appropriate optimization methods. In this paper, the weight and trajectory optimization results are obtained by using the commercial optimization tool, GPOPS-II. To investigate the effect of subsystem parameter and constraints on the optimization result, the sensitivity analysis is conducted.
