1. Autonomous Docking and Payload Handling Platforms

1.1.  In-Flight Recharging and Data Sharing System for Drones Using Overhead Power Lines

The Boeing Company, 2023

Systems and methods for in-flight recharging, data sharing, and metering of aircraft that fly near overhead power transmission lines. An unconnected power and data line is extended from an aircraft and can induce electrical currents from the changing magnetic fields around power lines. These currents are rectified and used to charge the aircraft's batteries and power systems, eliminating the need for landing and ground charging. The line can also transmit data between aircraft via the induced currents. The line can be extended between airborne aircraft by lowering it down and connecting gripper balls.
