Dynamics of a split torque helicopter transmission [PDF]
6th International Power Transmission and Gearing Conference: Advancing Power Transmission Into the 21st Century, 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.

Spin-torque efficiency enhanced by Rashba spin splitting in three dimensions [PDF]
Physical Review B, 2012 We examine a spin torque induced by the Rashba spin-orbit coupling in three dimensions within the Boltzmann transport theory. We analytically calculate the spin torque and show how its behavior is related with the spin topology in the Fermi surfaces by ...

Split Torque Transmission Load Sharing [PDF]
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 1994 Split torque transmissions are attractive alternatives to conventional planetary designs for helicopter transmissions. The split torque designs can offer lighter weight and fewer parts but have not been used extensively for lack of experience, especially with obtaining proper load sharing.
