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.
