Abstract

A combined flying-driving vehicle having a hybrid propulsion system architecture, foldable wings, and rotatable propulsion devices that is capable of vertical take-off and landing (VTOL), fixed wing cruise, and legally operating one a roadway surface.

Claims

1. A combined flying-driving vehicle comprising:

a vehicle body comprising a passenger compartment comprising a front end and an aft end, wherein the vehicle body defines a longitudinal axis along a length thereof substantially parallel to a preferred direction of motion of the vehicle along a length thereof;

a plurality of wheels coupled to the body and configured to support the vehicle body on ground;

a ducted fan disposed at the aft end of the body, wherein the ducted fan defines a fan axis substantially parallel to the longitudinal axis;

at least two folding wings coupled to the body, wherein the folding wing are adapted to fold around wing folding axes substantially parallel to the longitudinal axis, and wherein the folding wings are adapted to transmit lift to the body during flight and provide less lift when folded;

a plurality of pods pivotably mounted to the folding wings; and

a plurality of propeller blades pivotably mounted about a folding axis to the pods.

2. The combined flying-driving vehicle of claim 1, wherein the wheels are adapted to be retracted into the body during flight.

3. The combined flying-driving vehicle of claim 1, wherein each pod comprises at least one electric motor.

4. The combined flying-driving vehicle of claim 1 further comprising at least one of an electric motor and a hydrocarbon fuel engine adapted to power the ducted fan.

5. The combined flying-driving vehicle of claim 1 further comprising a steering wheel adapted to turn the vehicle.

6. The combined flying-driving vehicle of claim 1 further comprising an accelerator pedal adapted to accelerate the vehicle during flight.

7. The combined flying-driving vehicle of claim 1 further comprising a brake pedal adapted to decelerate the vehicle during flight.

8. The combined flying-driving vehicle of claim 1 further comprising at least one digital computer with at least one power source adapted to stabilize and control the vehicle.

9. The combined flying-driving vehicle of claim 8, wherein the at least one digital computer is wirelessly networked to a data source comprising data about at least one of real-time traffic, weather, and airspace.

10. The combined flying-driving vehicle of claim 8, wherein the digital computer is adapted to interpret high level commands from the operator to operate the vehicle substantially autonomously.

11. The combined flying-driving vehicle of claim 1 further comprising pod doors on sides of the vehicle body adapted to enclose the pods when the wings are folded.

12. The combined flying-driving vehicle of claim 1, wherein the pods are adapted to pivot about pivot locations substantially aligned with a vertical and longitudinal center of gravity of the vehicle.

13. The combined flying-driving vehicle of claim 1, wherein each propeller blade is pivotably mounted about an axis substantially parallel to a root chord of the propeller blade.

14. A combined flying-driving vehicle comprising:

a vehicle body comprising a passenger compartment comprising a front end and an aft end, wherein the vehicle body defines a longitudinal axis along a length thereof substantially parallel to a preferred direction of motion of the vehicle along a length thereof;

at least one motor;

a plurality of wheels coupled to the body and in a drive mode coupled to the at least one motor, the plurality of wheel being configured to support the vehicle body on ground;

a ducted fan disposed in the aft end of the body and structured and arranged to provide horizontal propulsion during flight, wherein the ducted fan defines a fan axis substantially parallel to the longitudinal axis;

at least two folding wings coupled to the body, wherein the folding wing are adapted to fold around wing folding axes substantially parallel to the longitudinal axis, and wherein the folding wings are adapted to transmit lift to the body during flight and provide less lift when folded, wherein the folding wings are disposed on first and second sides of the vehicle body and each of the folding wings is structured and arranged to fold along one of the sides of the body;

a plurality of pods pivotably mounted to the folding wings; and

a plurality of foldable propeller blades pivotably mounted to the pods and configured to fold against the pods when in a stowed position.

15. The combined flying-driving vehicle of claim 14, wherein each pod comprises at least one electric motor.

16. The combined flying-driving vehicle of claim 14 further comprising at least one of an electric motor and a hydrocarbon fuel engine adapted to power the ducted fan.

17. The combined flying-driving vehicle of claim 14 further comprising one or more of a steering wheel adapted to turn the vehicle, an accelerator pedal adapted to accelerate the vehicle, a brake pedal adapted to decelerate the vehicle.

18. The combined flying-driving vehicle of claim 14 further comprising at least one digital computer with at least one power source adapted to stabilize and control the vehicle, wherein the at least one digital computer is wirelessly networked to a data source comprising data about at least one of real-time traffic, weather, and airspace.

19. The combined flying-driving vehicle of claim 14 further comprising at least one digital computer with at least one power source adapted to stabilize and control the vehicle, wherein the digital computer is adapted to interpret high level commands from the operator to operate the vehicle substantially autonomously.

20. The combined flying-driving vehicle of claim 14 further comprising pod doors on sides of the vehicle body adapted to enclose the pods when the wings are folded.
