Flying batteries: In-flight battery switching to increase multirotor flight time

Karan P. Jain,Mark W. Mueller,Karan P. Jain,Mark W. Mueller

We present a novel approach to increase the flight time of a multirotor via mid-air docking and in-flight battery switching. A main quadcopter flying using a primary battery has a docking platform attached to it. A `flying battery' - a small quadcopter carrying a secondary battery - is equipped with docking legs that can mate with the main quadcopter's platform. Connectors between the legs and the...
