Aerodynamic Testing and Instrumentation of Components for Small Gas Turbines 670941

The relative merits of the engine or rig approach to aerodynamic testing of components for small gas turbines are briefly discussed. Rigs were used to test a centrifugal compressor to 91,000 rpm, cold flow turbines to 37,000 rpm, and for development of a plenum type exhaust duct. The latter two cases applied to the PT 6 free turbine engine. Facility, instrumentation, and operating experience are covered.
