    Abstract
  • Based on the cavitation theory of unattached expansion, the time-delay effect of supercavitation was considered, the vector from the empennage center of maneuverable supercavitating vehicle to supercavitation center in accompanying reference frame was established, and a motion control model of the vehicle was presented, which could describe the maneuverable motion property of the vehicle.Convenient for practical application, the model was simplified to straight-and-level flight without roll based on investigating the motion characteristics of the vehicle.The model is close and applied.It adequately considers the time-delay effect of supercavitation, accurately describes the motion characteristics of the vehicle at cruise phase and is the base of designing the motion control system of the vehicle.
