Dynamics of a split torque helicopter transmission [PDF]
, 1992 A high reduction ratio split torque gear train has been proposed as an alternative to a planetary configuration for the final stage of a helicopter transmission. A split torque design allows a high ratio of power-to-weight for the transmission.

Automatic identification of redundant gears in planetary gear trains
Mathematical and Computer Modelling, 1994 Redundant gears should be eliminated in the design of automatic transmissions in order to reduce inertial power loss and manufacturing costs. The purpose of this paper is to present a computerized method for the identification of redundant gears in planetary gear trains.

Global Analysis of a Planetary Gear Train [PDF]
Shock and Vibration, 2014 By using the Poincaré-like cell-to-cell mapping method and shooting method, the global characteristics of a planetary gear train are studied based on the torsional vibration model with errors of transmission, time-varying meshing stiffness, and multiple gear backlashes.
