Cavitator Design for Straight-Running Supercavitating Torpedoes

A practical cavitator design method for straight-running-type supercavitating torpedoes was developed in this paper. Design requirements were first drawn terms of torpedo performance characteristics, such as maximum range and motion stability. This determines the optimum satisfying that not only minimize total drag torpedo, extending range, but also provide hydrodynamic forces required straight level flight. The procedure includes determining a cavitation number type (disk or cone) obtaining optimal minimizes To determine an cavitator, equations force moment equilibrium flight iteratively solved by existing mathematical models cavity shapes generated disk- cone-shaped cavitators acting on vehicle. For validation, model experiments small-scale vehicle conducted towing tank, results agree well with those used study. preliminary based newly proposed implemented realistic More precise computations using CFD should be to investigate physics more detail near future.
