Abstract : The high speed maneuvering control of amphibious hovercraft involves a careful balance of aerodynamic and hydrodynamic forces and control effectors. Hovercraft maneuvering control can be either extremely precise or practically non-existent according to the selection and placement of control devices. A wide variety of options are available to the hovercraft designer who must match mission requirements against design complexity, reliability and cost considerations. These tradeoffs must be accomplished through reliable methods for maneuvering prediction and analysis including direct and supporting experimental methods. The development of hovercraft simulations is discussed with an emphasis on the practical experience gained in recent years by the U.S. Navy in amphibious hovercraft operations at all speeds over water and solid terrain. A specific data based simulation which requires extensive tow tank testing is presented and the tankery requirements are defined. (Author)
