ABSTRACT:
An integrated drive-generator system in which a casing housing a constant speed drive unit is attached to a casing housing a generator unit with means being provided to isolate mechanically debilitating debris within the unit which expelled it and so avoid damaging the other unit. The units share a common lubrication-coolant fluid system which provides fluid circulation to both from a reservoir. Expelled debris is isolated within the faulty unit by a barrier partition which separates the interiors of the units' casings and supports a breather which promotes fluid communication between the units' casings and permits a single pressurizing device to service both units. A scavenge pump for extracting fluid from each unit and transmitting it to the reservoir is located within the unit it services. As a result, if debris expelled by either unit becomes entrained in the fluid of that unit, only the scavenge pump within that unit will be damaged or jammed and system repair will be limited to the faulty unit. Thus, the units are cooperatively integrated as regards their functioning, but are effectively segregated as regards debilitating debris within the debris originating unit so as to isolate and minimize the damage to the system.
