  • Pitch control capacitance coupling
    Patent number: 4756667
    Abstract: A master controller 14 on the stationary side of a propeller system 10 sends pitch control signals via a communications link 34 which comprises a pair of capacitors 64, 66, each capacitor having a stationary plate and a rotating plate, one capacitor forming a high potential signal path, the other capacitor forming a low potential return path, across a rotating gap to a slave controller 54 on the rotating side of the propeller system which sets blade pitch according to the pitch control signals and sends pitch position signals back through the communications link to the master controller.
