Abstract: For solving the torpedo shape optimization design problem in low-drag, low-noise and high-maneuverability, based on MDO theory, using the algorithms of bi-level integrated system synthesis (BLISS) and concurrent subspace optimization (CSSO),a multidisciplinary optimization algorithm for solving the torpedo shape integrated optimization design is represented in this paper. The system level optimization model is established, the coupling problem between system and discipline level are solved by using quadratic response surface method. Finally, the effectiveness of analysis and optimization methods, models and calculation programs are verified through the examples, a better project in comprehensive performance was obtained.
