Abstract
A surveillance aircraft recharging system based on energy collection by magnetic induction from the current flowing in a randomly selected alternating current transmission line conductor. The charging energy originates in the magnetic field surrounding the current carrying conductor and is obtained by way of a laminated magnetic circuit surrounding the current carrying conductor and disposable in both an open and transmission line receiving state and a closed and energy collecting state upon command. Latching of the magnetic structure into a condition providing physical suspension stability for the host aircraft as well as an efficient magnetic circuit are provided. Latching of the magnetic structure includes a docking aircraft kinetic energy storage sequence assisting in aircraft deceleration and also providing saved energy useful during an undocking sequence.
