  • Turbine engine with differential gear driven fan and compressor
    Patent number: 8561383
    Abstract: A gas turbine engine (10) provides a differential gear system (58) coupling the turbine (20) to the bypass fan (14) and the compressor (16). In this manner, the power/speed split between the bypass fan and the compressor can be optimized under all conditions. In the example shown, the turbine drives a sun gear (74), which drives a planet carrier (78) and a ring gear (80) in a differential manner. One of the planet carrier and the ring gear is coupled to the bypass fan, while the other is coupled to the compressor.
    Type: Grant

  • Coupling system for a planetary gear train
    Patent number: 5433674
    Abstract: A coupling system including a sun gear coupling (32) and a ring gear coupling (158) for connecting the sun gear(36) and the ring gear housing (50) of a planetary gear train (26) to an external shaft (24) and an external mechanical ground (56) respectively are each characterized by undulant cross sections for accommodating parallel and angular misalignments. A ring gear deflection limiter (158), antirotation spline (190) and vibration damper are also included for enhanced operation.
