    Abstract
  • The major partial surfaces of supercavitation vehicle are wrapped by the bubbles of supercavitation, which forms a new hydrodynamic distribution as the vehicle running in water. Therefore, the vehicle′s motion mode is fully different from conventional one with complicated force state and nonlinear hydrodynamic force. To analyze the force characteristics of the vehicle, it is necessary to linearize the planing force and cavity lift. This paper describes the shape of cavity, discusses the major parameters affecting cavity shape, analyzes and linearizes the planing force and cavity lift. Simulation results show that the forces are linear within a certain scope. The motion characteristics of the vehicle can be analyzed further by using these linearized forces.
