Abstract
A fairing system for a rotary wing aircraft is provided including a shaft fairing mounted for rotation about a first axis of rotation. A de-rotation system contained with the shaft fairing includes a toroidal continuously variable transmission configured to control the rotation of the shaft fairing about the first axis of rotation. A position control system includes at least one position sensor and a controller. The at least one position sensor is configured to monitor a position of the shaft fairing relative to the first axis of rotation. The controller is operably coupled to the at least one position sensor and the de-rotation system. The controller is configured to adjust a gear ratio of the toroidal continuously variable transmission in response to a sensed position of the shaft fairing.
