Helicopter transmission arrangements with split-torque gear trains [PDF]
, 1983 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 ...
