Abstract
A transmission for providing mechanical power from an input includes a transmission assembly having an arm configured and adapted to be connected to a mechanical input for rotation at an input speed. A first planet is rotatably mounted to a first end of the arm. A trim ring operatively contacts the first planet for mutual rotation therewith. A brake is operatively connected to the trim ring for controlling rotation of the trim ring. A second planet is rotatably mounted to a second end of the arm. The second planet operatively contacts the first planet for mutual rotation therewith. An output ring operatively contacts the second planet for mutual rotation therewith to rotate at an output speed based on an input speed of the arm and a trim speed of the trim ring.
