Rotor tip light control |
摘要 |
A control circuit for controlling the intensity of a plurality of lights mounted at the ends of the rotor blades of a helicopter. The control circuit is completely self-contained and is powered by a wind-driven generator mounted to the blades. Commands to alter the intensity of the lights or to switch the lights on or off are transmitted by a pulsed light beam mounted on the helicopter tail boom.
