Abstract: An improved compound planetary gear system. In embodiments, a compound planetary gear system includes at least one planet pinion including a main shaft having a first gear for meshing with a sun gear and a second gear for meshing with a ring gear, and a carrier for supporting the at least one planet pinion. Teeth of the first gear are configured with a first helical angle with respect to a longitudinal angle of the at least one planet pinion, teeth of the second gear are configured with a second helical angle with respect to the longitudinal angle of the at least one planet pinion, the first helical angle different from the second helical angle.

Abstract: A chip agitation system for use on a rotorcraft with an engine and transmission system. The chip agitation system is configured to produce a mass flux of fluid to agitate chip debris towards a chip detection device. The chip agitation system includes a reservoir and valve that can be selectively opened and closed.
