Accelerated Mission Test of a TF41 with Aircooled Second Stage Turbine Blades.
Abstract
An accelerated mission test (AMT) of a TF41 was conducted in the Air Force Aero Propulsion Laboratory's '3' stand sea level engine test facility between 10 August 1977 and 26 October 1977. The primary objective of the test was to evaluate the structural reliability of a set of aircooled second stage high pressure turbine blades under realistic usage conditions. A two hundred sixty three hour test program was initially planned but only one hundred sixty hours were actually completed due to a variety of problems. A post-test teardown inspection revealed that six of the new aircooled blades had indications of fatigue cracks near the leading edge of the blade on the suction side. (Author)
