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;
- providing a first oil pump that includes a first oil supply element and a first scavenging element and a second oil pump that includes a second oil supply element and a second scavenging element;
- coupling the first oil pump and the 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 via the first scavenging element and such that the second oil pump is in flow communication with, and receives scavenge oil from, the second scavenge port via the second scavenging element;
- coupling the first oil supply element in flow communication to an oil supply source for receiving oil therefrom;
- coupling the second oil supply element in flow communication to the oil supply source for receiving oil therefrom;
- and
- coupling an output of the second oil supply element to the output of the first oil supply element to provide a combined output flow.
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 comprising a first oil supply element and a first scavenging element, wherein said first scavenging element is coupled in flow communication with said first scavenge port for receiving scavenge oil therefrom, and wherein said first oil supply element is coupled in flow communication with said oil supply source for receiving oil therefrom;
- and
- a second oil pump comprising a second oil supply element and a second scavenging element, wherein said second scavenging element is coupled in flow communication with said second scavenge port for receiving scavenge oil therefrom, and wherein said second oil supply element is coupled in flow communication with said oil supply source for receiving oil therefrom, the first oil supply element having an output fluidly coupled to an output of the second oil supply element to provide a combined output flow.
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 comprising a first oil supply element and a first scavenging element, wherein said first scavenging element is coupled in flow communication with said first scavenge port for receiving scavenge oil therefrom and wherein said first oil supply element is coupled in flow communication with said oil supply for receiving oil therefrom;
- and
- a second oil pump comprising a second oil supply element and a second scavenging element, wherein said second scavenging element is coupled in flow communication with said second scavenge port for receiving scavenge oil therefrom and wherein said second oil supply element is coupled in flow communication with said oil supply for receiving oil therefrom, the first oil supply element having an output fluidly coupled to an output of the second oil supply element to provide a combined output flow.
