Abstract

A vehicle including a fuselage, at least one lift-producing propeller carried by the fuselage on each side of its transverse axis a pilot'"'"'s compartment formed in the fuselage between the lift-producing propellers and substantially aligned with the longitudinal axis, and a pair of payload bays formed in the fuselage between the lift-producing propellers and on opposite sides of the pilot'"'"'s compartment. Many variations are described enabling the vehicle to be used not only as a VTOL vehicle, but also as a multi-function utility vehicle for performing many diverse functions including hovercraft and ATV functions.

Claims

1. A vehicle, comprising:

a fuselage having a longitudinal axis and a transverse axis;

at least one lift-producing propeller carried by said fuselage on each side of said transverse axis;

a pilot'"'"'s compartment formed in said fuselage between said lift-producing propellers and substantially aligned with said longitudinal axis;

and a pair of payload bays formed in said fuselage between said lift-producing propellers and on opposite sides of said pilot'"'"'s compartment,

wherein the cover of each of said payload bays is pivotally mounted to the fuselage alone an axis parallel to said longitudinal axis of the fuselage at the bottom of the respective payload bay, such that when the cover is pivoted to said open position it serves as a support for supporting the payload or a part thereof in the respective payload bay.

2. The vehicle according to claim 1, wherein each of said payload bays includes a cover deployable to an open position providing access to said payload bay, and to a closed position covering the payload bay.

3. The vehicle according to claim 1, wherein said lift-producing propellers are ducted fans.

4. The vehicle according to claim 1, wherein said lift-producing propellers are unducted fans.

5. The vehicle according to claim 1, wherein said fuselage carries a pair of said lift-producing propellers on each side of said transverse axis.

6. The vehicle according to claim 1, wherein said fuselage further carries a vertical stabilizer at the rear end of the fuselage.

7. The vehicle according to claim 1, wherein said fuselage further carries a horizontal stabilizer at the rear end of the fuselage.

8. The vehicle according to claim 1 wherein said fuselage further carries a pair of pusher propellers at the rear end of the fuselage on opposite sides of said longitudinal axis.

9. The vehicle according to claim 8, wherein said fuselage carries two engines, each for driving one of said lift-producing propellers and pusher propellers, said two engines being mechanically coupled together in a common transmission.

10. The vehicle according to claim 9, wherein said two engines are located in engine compartments in pylons formed in said fuselage on opposite sides of said longitudinal axis.

11. The vehicle according to claim 7, wherein said two engines are located in a common engine compartment aligned with said longitudinal axis and underlying said pilot'"'"'s compartment.

12. The vehicle according to claim 1, wherein the vehicle is a vertical take-off and landing (VTOL) vehicle.

13. The vehicle according to claim 1, wherein the vehicle includes a flexible skirt extending below the fuselage enabling the vehicle to be used as a hovercraft for movement over ground or water.

14. The vehicle according to claim 1, wherein the vehicle includes large wheels attachable to the rear end of the fuselage for converting the vehicle to an all terrain vehicle (ATV).

16. The vehicle according to claim 13, wherein said fuselage carries a pair of pusher propellers at the rear end of the fuselage on opposite sides of its longitudinal axis.

15. A vehicle, comprising:

a fuselage having a longitudinal axis and a transverse axis;

at least one lift-producing propeller carried by said fuselage on each side of said transverse axis;

a pilot'"'"'s compartment formed in said fuselage between said lift-producing propellers and substantially aligned with said longitudinal axis;

and a pair of payload bays formed in said fuselage between said lift-producing propellers and on opposite sides of said pilot'"'"'s compartment,

wherein the vehicle is a vertical take-off and landing (VTOL) vehicle, and wherein said VTOL vehicle includes a pair of stub wings each pivotally mounted under one of said payload bays to a retracted, stored position, and to an extended, deployed position for enhancing lift.
