[0021] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

The wording "and / or" used here includes all or any unit and all combinations of one or more associated listed items.
[0023] like Figures 1 to 4 As shown, the utility model relates to a full-lift air cushion catamaran, comprising a hull 1, an engine, a ducted air propeller 2, a lift fan 3, a rudder 4 and a full-finger skirt 5, the hull 1 comprises a hull 11 and a hollow sheet 12, both sides of the lower part of the hull 11 are connected to the sheet 12, the engine is arranged on the hull 11, the ducted air propeller 2 is located behind the hull 11, the rudder 4 is arranged behind the ducted air propeller 2, the lift fans 3 are installed on the two sheet bodies 12, the engine is transmission-connected with the ducted air propeller 2 and the lift fan 3, the bottom of the sheet body 12 is circumferentially provided with a full-finger skirt 5, and the interior of the full-finger skirt 5 is connected with the interior of the sheet body 12.
[0024] In the utility model, by combining an air cushion craft and a catamaran, the catamaran has a larger width, better lateral stability, and can have a certain obstacle crossing capability and a certain buoyancy. Due to the arrangement of the full-finger skirt 5 at the bottom of the air cushion craft, when the cushioning fan 3 is running, the wind can be blown to the full-finger skirt 5, so that the full-finger skirt 5 is lifted to a certain height, which can effectively reduce the power. Therefore, the full-lift air cushion catamaran of the present application combines the characteristics of the air cushion craft and the catamaran, sacrifices part of the lateral obstacle crossing capability to improve the longitudinal obstacle crossing capability, and is also beneficial to reduce the cushioning power required for high obstacle crossing. At the same time, the bottom of the two sheets 12 are provided with full-finger skirts 5 to have better stability, so that there is no need for a special apron design or special device to ensure longitudinal and lateral stability.
[0025] In this embodiment, the front end and the rear end of the upper part of the sheet body 12 are provided with the lifting fan 3, that is, the lifting fan 3 is four, one of which is provided with the lifting fan 3 at the front end and the rear end of the upper part of the sheet body 12, and the front end and the rear end of the other sheet body 12 are also provided with the lifting fan 3. The engine can drive the lifting fan 3 to operate through a transmission mechanism such as a belt drive, a drive shaft drive or a hydraulic drive system, so that the lifting fan 3 can provide sufficient lifting force. The lifting fan 3 can be an axial flow or centrifugal lifting fan 3.
[0026] Moreover, the air is blown into the sheet body 12 by the cushion-lifting fan 3 and then directly poured into the full-finger apron 5, so the air passage is simple, thereby reducing the loss.
[0027] In this embodiment, two ducted air propellers 2 are provided, and the two ducted air propellers 2 are arranged side by side behind the hull 11. The rudder 4 is provided behind the two ducted air propellers 2. The engine can drive the ducted air propellers 2 to operate through a transmission mechanism such as a belt drive, a drive shaft drive or a hydraulic transmission system to provide sufficient propulsion force.

[0029] By providing the engine compartment 6, the engine can be installed and fixed, and the engine can be protected.
[0030] In this embodiment, the hull 11 and the sheet body 12 are fixedly connected by fixing members. Specifically, the fixing members are bolts or rivets, so as to firmly fix the hull 11 and the sheet body 12 together to ensure the stability of the full-lift air cushion catamaran.
[0031] Preferably, the hull 1 is made of aluminum alloy or fiberglass, that is, the hull 11 and the sheet 12 are both made of aluminum alloy or fiberglass, so as to have sufficient structural strength and better corrosion resistance.
