Research on Multidisciplinary Integrated Design and Optimization System of Tactical Missile

Aiming at the problem of multidisciplinary coupling design of short-range tactical missile, an overall design model with minimum takeoff mass as the optimization objective is established. Based on the integrated design method, Aerodynamics, Motor, Mass Properties, Trajectory and other disciplines are analysed and their models are established. The multidisciplinary design optimization integration framework is constructed, and a missile multidisciplinary integrated design system is established through the program encapsulation, which can realize the coupling design and the overall parameter optimization of each subdiscipline. The system can design, analyze, simulate and optimize functions both system and subsystem, provide methods for optimization of aircraft programs and parameters, and support design schemes management in different technical states. The simulation results show that the system has obvious optimization effect and practical engineering.
