Hydraulically Driven Local Pump

Abstract:

A gas turbine engine includes a compressor section, a combustion section, and a turbine section arranged in serial flow order; a casing surrounding the compressor section, the combustion section, and the turbine section; a first system comprising a first system fluid line, the first system fluid line including a first system fluid therein; and a second system including a hydraulic motor, the hydraulic motor positioned within the casing and fluidly coupled to the first system fluid line such that a flow of the first system fluid through the first system fluid line drives the hydraulic motor, the second system further including a fluid pump and a second system fluid line, the hydraulic motor drivingly coupled to the fluid pump, the fluid pump operable with the second system fluid line for providing a flow of a second system fluid through the second system fluid line during operation.
