ABSTRACT:
A segregated fluid management system and method is provided for a SDG or IDG system. There is a full case hydraulics (24), a gear case section (19) and a generator section (25). The full case hydraulics section (24) operates completely full of oil. A charge pump (34) draws from the full case (33) inside this section (24) and discharges oil from the case (33) to the pump and motor (26), the servo valve (29), the control piston (30) and the charge relief valve (31). The gear case section (19) is operated as a dry sump by a scavenge pump (17) which keeps the gear case cavity from accumulating an appreciable amount of oil. The scavenge pump (17) removes oil from the gear case section (19) and routes it through a filter (35) to the full case hydaulics section (24). The generator section (25) is conduction cooled and has a pitot pump (40) arranged in an air gap (39 ) between the generator rotor (37) and the stator (38). Oil is evacuated out of the generator section (25) through both the pitot pump (40) and a stator discharge (41) associated with the sump (18) in the gear case section (19).
