摘要

A dynamic model is developed for vertical-plane motions of a hydroplane boat supported by aerodynamic, hydrodynamic, and propulsive forces. The model is based on unsteady nonlinear formulations of the extreme ground effect theory for the hydroplane platform and the added-mass strip theory for planing hulls. The steady-state attitudes, thrust-to-weight ratios, and static stability margins are calculated for a selected hydroplane configuration with several variable parameters. Simulations of unsteady regimes are also carried out, including responses to an initial disturbance, reactions to wind gusts, and motions in head and following regular waves. The developed model can be applied for aero-hydrodynamic design of hydroplanes with realistic geometries and other types of air-supported high-speed boats.
