Investigation of Integrated Multi-disciplinary and Multi-objective Optimization of the Torpedo Shape Design Method

A multi-disciplinary and multi-objective optimization of the torpedo shape design method was proposed. The design model for integrated multi-disciplinary and multi-objective optimization of the torpedo shape was built. The frame of improved concurrent subspace optimization algorithm was pro- Dosed. An example of the torpedo shape optimization design was given. The optimized results were compared with the original shape. The compared results show that the optimized performances in the respects of hydrodynamics and acoustics are greatly improved, and the proposed method is feasible and adaptable.
