Patent ID: 7219854

Claim:
A wing in-ground effect flight vehicle which comprises: a fuselage formed with at least one chamber filled with a volume of lighter-than-air gas to provide lift for said vehicle, said fuselage defining a longitudinal axis; a wing fixedly mounted on said fuselage, said wing being substantially symmetrical relative to a plane containing the axis; a first cycloidal propulsion unit mounted on said fuselage to operate in a selected mode for generating a first thrust vector substantially in the plane of symmetry; and a second cycloidal propulsion unit mounted on said fuselage to operate in a selected mode for generating a second thrust vector substantially in the plane of symmetry, wherein said second cycloidal propulsion unit is axially distanced from said first cycloidal propulsion unit and cooperates therewith to provide said wing in-ground effect flight vehicle with thrust, lift and longitudinal stability to maintain a predetermined altitude for wing-in-ground effect flight.
