National Transonic Facility (NTF) Prototype Fan Blade Fatigue Test.

Abstract

The Applied Technology Laboratory conducted fatigue tests on a composite fan blade designed for use in the new NTF wind tunnel being constructed at NASA-Langley. The tests were performed by the Structures Technical Area using the root end fatigue machine (REFM), which was modified for ground-air-ground testing. Simulated centrifugal and aerodynamic (bending) load tests were performed. The fan blade successfully withstood 6000 cycles at 360 rpm and 600 rpm load conditions for the cyclic rate tests. These tests simulated the starting and stopping cycles of the fan. Static load tests to 57,000 pounds design load were also successfully performed on the blade specimen. (Author)
