摘要： A flow transfer apparatus for transferring cooling flow from a primary gas flowpath (P) to a turbine rotor (128). The apparatus includes: a first supply plenum (92) communicating with the primary gas flowpath (P) and first inducers (148 A), the first inducers (148 A) configured to accelerate a first fluid flow from the first supply plenum (92) and discharge it toward the rotor with a tangential velocity; a second supply plenum (96) communicating with the primary gas flowpath (P) and second inducers (148B), the second inducers (148B) configured to accelerate a second fluid flow from the second supply plenum (96) towards the rotor with a tangential velocity; and a cooling modulation valve (98) operable to selectively permit or block the second fluid flow from the primary gas flowpath (P) to the second supply plenum (96). The valve includes a flow control structure (108, 110) disposed in the primary gas flowpath (P) and an actuation structure extending to a location radially outside of a casing (76) defining the primary gas flowpath (P).

摘要： A gas turbine engine comprising a cyclonic separator provides fluid communication between the compressor section and the turbine section. The cyclonic separator comprises an annular volume receiving a flow of cooling fluid from an inlet and dividing the airflow into a cleaner air outlet and a scavenge outlet. The flow of cooling fluid is provided to the cyclonic separator in a direction tangential to the annular volume such that a cyclonic flow of cooling fluid moves within the annular volume centrifugally separating particles entrained within the airflow to the radial outer area of the annular volume for removal through the scavenge outlet and providing a cleaner airflow to the cleaner air outlet.

摘要： A passive clearance control limits thermal expansion between stator components relative to rotor components. A control ring 40 controls clearance in a passive manner and is located on or adjacent to stationary components which thermally expand during engine operation. The control ring is formed of material having low coefficient of thermal expansion such as CMCs (Ceramic Matrix Composites) and therefore limits, inhibits or restrains expansion of the adjacent stator components 32 as temperatures increase. Limiting expansion of the stator component reduces rotor/stator clearances and limits parasitic leakage of fluid along the flowpath through the engine core.
