A mathematical model to analyze the static stability of hybrid (aero-hydrodynamically supported) vehicles

Among the new concepts developed for high speed marine vehicles over the last two decades [1], the ‘aerodynamic alleviation’ [2] approach consists in using an aerodynamic surface to ‘alleviate’ the weight sustained by the hydrodynamic lift. Such vehicle experiences aerodynamic and hydrodynamic forces of the same order of magnitude, therefore the dynamic models developed for airborne and waterborne vehicles are not suitable.
