Abstract
A method facilitates assembling a gas turbine engine that includes an oil supply and scavenge system, wherein the oil supply and scavenge system includes at least one sump cavity that includes a first scavenge port and a second scavenge port, a first oil pump and a second oil pump such that the first oil pump is in flow communication with and receives scavenge oil from the first scavenge port and the second oil pump is in flow communication with and receives scavenge oil from the second scavenge port. In addition, an oil supply source is coupled in flow communication with the first and second oil pumps.
Claims20
A method of assembling a gas turbine engine, said method comprising the steps of;
- providing an oil supply and scavenge system including at least one sump cavity that includes a first scavenge port and a second scavenge port;
- coupling a first oil pump and a second oil pump in flow communication with the oil supply and scavenge system, such that the first oil pump is in flow communication with, and receives scavenge oil from, the first scavenge port and such that the second oil pump is in flow communication with, and receives scavenge oil from, the second scavenge port;
- and
- coupling an oil supply source in flow communication with the first and second oil pumps.
An oil supply and scavenge system for a gas turbine engine, said oil supply and scavenge system comprising:
- at least one sump cavity;
- an oil supply source;
- a first scavenge port and a second scavenge port each coupled in flow communication with said at least one sump cavity;
- a first oil pump coupled in flow communication with said first scavenge port for receiving scavenge oil therefrom, and said oil supply source;
- and
- a second oil pump coupled in flow communication with said second scavenge port for receiving scavenge oil therefrom, and said oil supply source.
A gas turbine engine comprising;
- a gearbox coupled to said gas turbine engine;
- an oil supply and scavenge system, said oil supply and scavenge system comprising at least one sump cavity and an oil supply source;
- said oil supply and scavenge system further comprising a first scavenge port and a second scavenge port each coupled in flow communication with said at least one sump cavity;
- a first oil pump coupled in flow communication with said first scavenge port for receiving scavenge oil therefrom and in flow communication with said oil supply;
- and
- a said second oil pump coupled in flow communication with said second scavenge port for receiving scavenge oil therefrom and in flow communication with said oil supply.
