Ground-effect hovercraft vehicle with retractable wings
View Patent ↗A ground-effect amphibious hovercraft vehicle having a system of retractable wings ( 8 ), which are retracted (parking mode) by retracting arms ( 17 a and 17 b ) of both wings by a head ( 19 ). At the same time, the vehicle acts as a ground-effect hovercraft vehicle when the wings ( 8 ) are extended (flight mode), which is done by extending the arms ( 17 a and 17 b ) of both wings by the head ( 19 ). The head ( 19 ) is extended/retracted using a cylinder ( 22 ) moved by a drive motor ( 18 ), which may be an electric motor, a hydraulic motor or a mechanical motor, or manually using cables and pulleys.
1 . A hovercraft comprising retractable wings ( 8 ) having extender/retractor arms ( 17 a and 17 b ) connected by means of a retracting/extending head ( 19 ), wherein the head ( 19 ) is extended/retracted by a cylinder ( 22 ), and is mobilized by a drive motor ( 18 ), wherein the retractable wings ( 8 ) are mounted on a wing mechanism box ( 20 ), wherein the wing mechanism box is installed between base plates ( 15 a and 15 b ), together with a structural reinforcement ( 14 ) under a chassis or fuselage of the hovercraft, wherein when the extender/retractor arms ( 17 a and 17 b ) of the retractable wings ( 8 ) are extended flight mode), the hovercraft is configured in ground effect hovercraft mode, and when the extender/retractor arms ( 17 a and 17 b ) of the retractable wings ( 8 ) are retracted (parking mode), the hovercraft is configured in amphibious hovercraft mode.
2 . The hovercraft according to claim 1 , wherein the retracting/extending head ( 19 ) allows extension/retraction of the extender/retractor arms through hinge axes ( 21 a and 21 b ) of a right wing and hinge axes ( 21 c and 21 d ) of a left wing of the retractable wings.
3 . The hovercraft according to claim 1 , wherein the retracting/extending head ( 19 ) and the structural reinforcement ( 14 ) further comprises front and rear beams ( 25 and 26 ), upper adjustment and rolling rollers ( 24 a and 24 b ), and lower adjustment and rolling rollers ( 24 c and 24 d ) which maintain the retractable wings' load.
4 . The hovercraft according to claim 1 , wherein the wing mechanism box ( 20 ) comprises an upper adjustment and rolling roller ( 30 a ) and a lower adjustment and rolling roller ( 30 b ).
5 . The hovercraft according to claim 1 , wherein the retractable wings ( 8 ) further comprises flaps, improving the lift, and ailerons ( 11 ), which together with a rudder ( 4 b ), facilitate and have greater control of turns, and wherein a “winglet” devices ( 13 ) eliminates the effects of turbulence that could be generated in the wings.
6 . The hovercraft according to claim 1 , wherein the wing mechanism box ( 20 ) comprises a drive pinion ( 27 ) that is driven by motor and reducer, a receiving pinion ( 28 ), which is integrally joined to the front beam ( 25 ), which performs oscillation sliding in a guide ( 29 ).
7 . The hovercraft according to claim 1 , wherein the drive motor ( 18 ) is selected from the group consisting of electric, hydraulic, mechanical, and manual motor.
8 . The hovercraft according to claim 1 , wherein the drive motor ( 18 ) comprises cables and pulleys.
