Multidisciplinary Design Optimization and Simulation Validation for Shape Design of Torpedo

Concurrent Subspace Design based on Response Surface(RS-CSD) is an effective method for complex systems design.The shape design of torpedo was divided into two disciplines: drag reduction design and noise reduction design,and how to use RS-CSD to optimization shape design of torpedo was explained in details.In the end optimization design and simulation testing using FLUENT software of a certain torpedo were given.Optimization results and simulation results also indicate that the drag and noise of optimal shape are improved.
