Kinematic Operating Modes of Two-Speed Two-Carrier Planetary Gear Trains with Four External Shafts [PDF]
Two-speed planetary gear trains with four external shafts, composed of two simple planetary gear trains, are considered in this paper. The labelling system of these trains is defined and all possible variants are determined.

Helicopter transmission arrangements with split-torque gear trains [PDF]
As an alternative to component development, the case for improved drive-train configuration is argued. In particular, the use of torque-splitting gear trains is proposed as a practicable means of improving the effectiveness of helicopter main ...
