摘要： A toy air cushion vehicle comprising a hull the lower portion of which carries a skirt bounding the air cushion space, an electrically driven lift fan having a substantially vertical axis, at least one propulsion unit mounted on the hull and comprising an electrically driven propeller, and at least one movable weight for balancing the vehicle on its air cushion both in the transverse and longitudinal directions. The skirt has parts subdividing the cushion space. The hull has a compartment with a door automatically closed by the lift fan through a pneumatic device. The propeller may be a flexible member maintaining its shape partly by centrifugal force and may have a torque limiter including a magnetic or friction coupling.

摘要： A pressure-fluid cushion device for a ground-effect machine movable opposite a surface, which device comprises two sidewall structures extending substantially parallel to and on each side of the longitudinal medial plane of the machine and having a front end portion and a rear end portion, the sidewall structures having sufficient rigidity to resist deformation as a result of variable external forces acting on them during displacement of the machine and laterally defining a space between the machine and the said surface, chambers obstructing the space at the front and rear and extending between the sidewall structures, these chambers being bounded by flexible skirts deformable by such external forces, and means for supplying pressure fluid to the chambers and space.
