Abstract: Systems and methods for recharging the battery onboard an aircraft (hereinafter “receiving aircraft”) via resonant inductive coupling. In accordance with some embodiments, wireless power transfer to the receiving aircraft is effected by means of a second aircraft (hereinafter “transmitting aircraft”). The receiving and transmitting aircraft are both equipped with respective LC circuits. The aircraft fly in a formation such that transmit coils onboard the transmitting aircraft and receive coils onboard the receiving aircraft are separated by a distance within a resonant inductive coupling range. During the recharge procedure, each transmit coil is driven by an alternating current source having a frequency equal to the resonant frequency of the LC circuit onboard the receiving aircraft. The receive coils then feed the induced alternating current to a rectifier for supplying direct current to the onboard battery charger.
