ABSTRACT:
Cooling air delivery systems for gas turbine engines are used to increase component life and increase efficiencies. To change the flow rate of cooling air in past engines, major disassembly of engine components was required resulting in the loss of the engine's service and excessive costs. With the changeable cooling air delivery system of the present invention, major engine disassembly is eliminated. An elongate member extends into a fluid control passage to establish a preselected flow area which can be changed. The time and expense required to change the cooling flow rate is drastically reduced because the elongate members are accessible external of the engine. The elongate member is removed from the engine and replaced by different elongate member having a different outer diameter of the stem or sleeve. The different diameter results in a new clearance or preselected flow area for cooling air to pass therethrough.
