Configuration Analysis of Supercavitating Vehicles Based on Equivalent Pressure Center Method

Article Preview

Abstract:

Based on a detailed modeling of supercavitating flight, the Equivalent Pressure Center (EPC) method is proposed in this paper. To validating the proposed method, both of EPC and integrated moment, which are highly concerned during configuration design process for supercavitating motion, are studied for different configuration parameters including aspect ratio, fin position and cavitator size of the body. As the relative pitch angle between cavity and the vehicle would change with flight status, well designed vehicle configurations could produce better stability and maneuverability performances by locating the EPC close to the mass center. With detailed analysis of the EPC result, some of the propositional results for configuration parameters of supercavitating vehicles are given.
