Abstract
An oil system (118) for a tip turbine engine (10) includes an annular lubricating fluid plenum (136) which sprays lubricating fluid through a multitude of lubricating fluid passages (144, 146, 148) and into the multitude of passages (152, 154, 156) located within a gearbox assembly (90) as they revolve thereby. Lubricating fluid is thereby communicated directly into the gearbox assembly (90) and returned to a sump tank (140) through a multitude of drain passages.
