Abstract:
An in-flight battery recharging system for Unmanned Aerial Vehicle (UAV). This invention converts byproducts of a multi-rotor unmanned aerial vehicle's conventional propulsion system operation and airframe movements to generate electricity that, in turn, is used to power the propulsion system's electric motors, power onboard electronic components, and recharge the battery that initially powers the propulsion system's electric motors. Having this ability of recharging the battery in-flight gives an unmanned aerial vehicle a much improved flight time and range, thereby greatly increasing its utility.
