Build 1 of an Accelerated Mission Test of a TF41 with Block 76 Hardware.
Abstract
An accelerated mission test (AMT) of a TF41 (S/N 142163) was conducted in the Air Force Aero Propulsion Laboratory's 'D' bay sea level engine test facility between 18 Oct 77 and 13 Jan 78. The primary objective of the test was to evaluate the structural reliability of a series of parts changes known as 'Block 76' hardware under realistic usage conditions. A two hundred sixty three hour test program was initially planned but only one hundred and six hours were actually completed due to the failure of a second stage high pressure turbine blade. The second stage turbine had ben reworked and the verification of this rework scheme was a secondary objective of this test. The failure occurred at a reworked location but the actual cause of failure could not be determined. The post-test teardown inspection showed all of the Block 76 hardware to be in good condition.
