Abstract:
Unsteady rectilinear motion of an air-cushion vehicle over an ice sheet at various speeds is considered. Ice is modeled by a viscoelastic ice plate. The effects of the basin depth, the thickness and relaxation time of ice, vehicle length, acceleration, deceleration, and speed of uniform motion on the wave resistance of the vehicle are analyzed. Maneuvering methods for increasing or lowering the wave resistance of the vehicle are proposed.
