IN-FLIGHT BATTERY RECHARGING SYSTEM FOR AN UNMANNED AERIAL VEHICLE
First Claim
Patent Images
1. An in-flight charging system for an unmanned aerial vehicle (UAV), comprising:
- a hub portion,a motor attached to the hub portion via a support arm,a rotor rotationally driven by the motor to produce a thrust airflow; and
a prop oriented for rotational movement in the thrust airflow and operatively coupled to a generator via a generator shaft, the generator producing a first electrical charge responsive to the rotational movement of the prop with the thrust airflow.

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.
