Aerodynamically alleviated marine vehicle (original) (raw)

An aerodynamically alleviated marine vehicle (AAMV) is a high speed marine vehicle configuration that uses aerodynamically generated forces (lift) to ‘alleviate’ its weight. The advantage is that the hydrodynamic lift required to sustain the weight of the vehicle is diminished, leading to a diminished hydrodynamic drag. The vehicle is in constant contact with the water, therefore the aerodynamic surfaces operate in ground effect. The name derives from the '‘Aerodynamic Alleviation Concept’', presented by L.J. Doctors to illustrate the positive effect of using a wing-like superstructure on a catamaran configuration.
