Multi-modal vehicle
View Patent ↗The present invention relates to a multi-modal vehicle operable in a first mode as a fixed wing aircraft and reconfigurable to be operable in a second mode as a ground vehicle. The vehicle comprises first and second ends configured to operate in a first direction, with the first end leading the second end, in the first mode and in a second direction, with the second end leading the first end, in normal operation in the second mode.
1. A multi-modal vehicle operable in a first mode as a fixed wing aircraft and reconfigurable to be operable in a second mode as a ground vehicle, the vehicle having first and second ends and being configured to operate in a first direction in the first mode, with the first end leading the second end, and in a second direction, opposite the first direction, in the second mode, with the second end leading the first end, in normal operation the multi-modal vehicle comprising at least one retractable wheel configured to engage the ground in the second mode and an auxiliary wheel, the auxiliary wheel located at the second end of the vehicle, wherein the retractable wheel is configured to retract in an upward direction such that the auxiliary wheel is located relatively higher than the retractable wheel in the second mode so as not to contact the ground and is configured to engage the ground during retraction of the retractable wheel.
2. The multi-modal vehicle according to claim 1 , comprising a body, the body comprising an aerodynamic surface shaped to provide lift when operating in the first direction and/or shaped to provide downforce when operating in the second direction.
3. The multi-modal vehicle according to claim 2 , wherein the body is substantially aerofoil shaped along a longitudinal axis thereof, the leading edge of the aerofoil provided at the first end of the vehicle and the trailing edge of the aerofoil provided at the second end of the vehicle.
4. The multi-modal vehicle according to claim 2 , wherein the body is angled such that the first end of the vehicle is raised with respect to the second end of the vehicle.
5. The multi-modal vehicle according to claim 1 , wherein the vehicle comprises a first control system configured to allow an operator to control the vehicle in the first mode and a second, separate, control system configured to allow the operator to control the vehicle in the second mode.
6. The multi-modal vehicle according to claim 5 , wherein the first control system and the second control system are arranged in substantially opposing directions, the first control system being arranged such that the operator is facing the first direction and the second control system being arranged such that the operator is facing the second direction.
7. The multi-modal vehicle according to claim 5 , comprising a seat, the seat movable between a first position/orientation to allow the operator to operate the first control system and a second position/orientation to allow the user to operate the second control system.
8. The multi-modal vehicle according to claim 1 , wherein one or more wheel comprises a fairing, the fairing configured to act as a rudder in the first mode.
9. The multi-modal vehicle according to claim 1 , comprising one or more wings configured to generate lift in the first mode, wherein the one or more wings are retractable in a telescoping arrangement.
10. The multi-modal vehicle according to claim 1 , comprising an auxiliary aerofoil located proximal the first end of the vehicle and/or a second auxiliary aerofoil located proximal the second end of the vehicle.
11. The multi-modal vehicle according to claim 10 , wherein the first auxiliary aerofoil and/or the second auxiliary aerofoil is rotatable about a longitudinal axis thereof.
12. The multi-modal vehicle according to claim 10 , wherein the first auxiliary aerofoil and/or the second auxiliary aerofoil are retractable.
13. The multi-modal vehicle according to claim 1 , comprising a propeller for propelling the vehicle in the first mode.
14. The multi-modal vehicle according to claim 13 , wherein the propeller is located proximal the first end of the vehicle.
15. The multi-modal vehicle according to claim 13 , wherein one or more blades of the propeller are retractable/removable.
16. A method of operating a multi-modal vehicle according to claim 1 , comprising:
operating the vehicle in a first direction, with the first end leading the second end, in the first mode and operating the vehicle in a second direction, with the second end leading the first end, in normal operation in the second mode.
