Abstract
An oil tank assembly for a gas turbine engine may include an oil tank having an upper compartment and a lower compartment. A baffle may separate the upper compartment of the oil tank from the lower compartment of the oil tank. A de-aerator may be included, where the de-aerator includes an oil inlet, a de-aerator outlet, and an air vent. The de-aerator may be configured to separate air from oil in an air-oil mixture such that the oil flows through the de-aerator outlet and such that the air flow through the vent. Further, the de-aerator may include a fill port for receiving oil.
Claims20
An oil tank assembly for a gas turbine engine, the oil tank assembly comprising:
- an oil tank having an upper compartment and a lower compartment;
- a baffle separating the upper compartment of the oil tank from the lower compartment of the oil tank;
- a deaerator, wherein the deaerator includes a deaerator inlet, a deaerator outlet, and a vent, and wherein the deaerator inlet receives oil circulated by an oil pump, wherein the deaerator is configured to separate air from the oil in an air-oil mixture such that the oil flows through the deaerator outlet and such that the air flow through the vent;
- and a filler port formed by a first opening in an upper portion of the deaerator wherein the upper portion of the deaerator is located outside a reservoir of the oil tank, and wherein the deaerator outlet is located in the lower compartment of the oil tank and wherein the upper portion of the deaerator consists of a single opening with a diameter greater than ½ inch, and wherein the single opening accommodates the filler port and the deaerator inlet.
An oil tank assembly for a gas turbine engine, the oil tank assembly comprising:
- an oil tank having an upper compartment and a lower compartment;
