Abstract:
A hovercraft with at least one fan for producing an air cushion and at least one thrust unit, which acts on the top surface (4) of the craft, where the thrust unit serves to propel the craft and/or control its direction, and both the fan and the thrust unit have at least one airscrew that is driven by means of a motor (5, 6, 21) and generates an air current, characterised in that the motor (5, 6, 21) takes the form of an electric motor located directly on the airscrew, in that at least one central energy generator (7), which supplies the electric motor (E1, E2, A) with drive energy via an energy line (5a, 6a, 21a), is provided in order to generate the electrical drive energy required by said electric motor (E1, E2, A), in that at least one thrust unit is designed as a rotatable unit (2, 3), which can rotate about a vertical axis (2a, 3a) and is used for both propulsion and steering, and in that two rotatable units (2, 3) are provided, which are arranged in the direction of the lateral principal axis of inertia xâ€”x of the hovercraft, as well as mirror-symmetrical to its longitudinal principal axis of inertia yâ€”y.
