  • Phase and speed control system
    Patent number: 4245955
    Abstract: A phase and speed control system for synchronizing the speed and controlling the phase relationship between a pair of aircraft engines, each engine having associated therewith a centrifugal governor, includes a phase comparator circuit which provides a pulse width modulated signal only to the governor coil of the engine having the slower initial rotational velocity. A variable delay on one input of the phase comparator may be adjusted to determine the relative rotational phase relationship between the engines.
