The concept of supercavitating vehicle cavity pattern was introduced to describe in a unified way thevehicle shape,cavity shape,and their geometric matching.The hydrodynamic characteristics of supercavitating vehiclewere expressed by quantitative parameters.The mathematical model of supercarity in maneuvering rotational movement wasestablished,and the expression of supercavity shape in maneuvering rotational movement was deduced.The transition fromrectilinear motion to steady maneuvering rotational movement of supercavitating vehicle was analysed and the variation ofsupercavity shape was presented.The influences of angular velocity and centrifugal force on supercavity shape inmaneuvering rotational movement were discussed and the affection extent of these two factors were revealed.Taking thegeometric matching between cavity shape and vehicle shape as a constrant a preliminary assessment of maneuveringcapability was made,and the critical rotation angular velocity characterizing maneuvering capability was provided byunmerical simulation.
