    Abstract
  • The tail-slaps of supercavitating vehicle and the distortion of cavity shape are coupling with each other. The coupling motion equation of supercavitating vehicle was established and the tail-slaps of the vehicle influenced by the distortion of cavity shape were also analyzed in different conditions of velocity and initial angel velocity. The research results show that the vehicle-s rotating angel, movement cycle, lift force of tail-slaps and drag force of tail-slaps increase by the effect of the distortion of cavity shape. In different velocities, the vehicle-s rotating angel, movement cycle and tail-slap cycle, which are influenced by the distortion of cavity shape, decrease by the increment of velocity. In different angel velocities, the vehicle-s rotating angel, movement cycle and tail-slap cycle, which are influenced by the distortion of cavity shape, increase by the increment of angel velocity.
