Methods and apparatus to maintain a state of a fluid in a system are disclosed. An example system includes a pump including a primary inlet, a primary outlet, and a secondary inlet, at least one injector including a first inlet, a second inlet, and at least one outlet, a third conduit coupled to a first conduit upstream of the primary inlet and coupled to the at least one injector at the first inlet to deliver the fluid, a fourth conduit coupled to a second conduit downstream of the primary outlet and coupled to the at least one injector at the second inlet to deliver the fluid, and a fifth conduit coupled to the at least one injector at the at least one outlet to receive the fluid and coupled to the pump at the secondary inlet.

A cooling system for a turbine engine. The turbine engine includes a compressor, a turbine, and a shaft that drivingly couples the compressor and the turbine. The cooling system includes one or more cavities of the compressor. The cooling system includes a shaft flowpath defined in the shaft. The shaft includes one or more shaft apertures that provide fluid communication between the shaft flowpath and the one or more cavities. Air passes through the one or more shaft apertures and the shaft flowpath during a shutdown of the turbine engine to cool the one or more cavities.

A feeder duct assembly for a gas turbine engine, which negates the need for a ball or axial joint in the duct for required for flexibility under thermal loading. The feeder duct assembly of the present innovation comprises an end fitting designed to meet flexibility requirements without compromising dynamic performance of the system with added weight from ball or axial joints in the ducts.
