  • Method of and apparatus for driving aircraft generator at a constant-speed
    Patent number: 6561940
    Abstract: An output rotational driving power of the engine is split into a first split power and a second split power. The first split power is transmitted to a continuously variable speed transmission that transmits the first split power by a shearing resistance of a fluid. The second split power is transmitted to a differential planetary gear system. An output power of the continuously variable speed transmission is transmitted to the differential planetary gear system to combine the first split power and the second split power in the differential planetary gear system. A variation of a rotating speed of the output rotational driving power is absorbed by the continuously variable speed transmission to adjust an output rotating speed of the differential planetary gear system to a constant speed.
