Unmanned aerial vehicle
First Claim
1. A method of an unmanned aerial vehicle configured to glide within a geographic region, the unmanned aerial vehicle comprising a generator arranged to be driven by a rotor, the method comprising:
- defining a maximum altitude threshold for the geographic region, above which the unmanned aerial vehicle is not permitted to be flown;
identifying a location of at least one identified updraft within the geographic region;
manoeuvring the unmanned aerial vehicle within the identified updraft; and
harvesting energy from motion of the unmanned aerial vehicle within the updraft by regenerative braking of the rotor to thereby maintain an altitude at or below the maximum altitude threshold;
wherein at least one of the defining, the identifying, and the maneuvering is via a flight management system controlling the unmanned aerial vehicle; and
wherein the unmanned aerial vehicle is maneuvered within the identified updraft with a bank angle that controls the altitude of the unmanned aerial vehicle.

Abstract
The present disclosure relates to an unmanned aerial vehicle (UAV) able to harvest energy from updrafts and a method of enhancing operation of an unmanned aerial vehicle. The unmanned aerial vehicle with a gliding capability comprises a generator arranged to be driven by a rotor, and a battery, wherein the unmanned aerial vehicle can operate in an energy harvesting mode in which the motion of the unmanned aerial vehicle drives the rotor to rotate, the rotor drives the generator, and the generator charges the battery. In the energy harvesting mode regenerative braking of the generator reduces the forward speed of the unmanned aerial vehicle to generate electricity and prevent the unmanned aerial vehicle from flying above a predetermined altitude.
