Dynamic Testing of a Composite Material Helicopter Transmission Housing

Abstract

The program was carried out to investigate the integration of a GFE composite material gear housing into a UH-1 bench test transmission. The composite material housing was designed to replace a conventional magnesium sand cast housing. A test program using the composite housing was outlined to: (1) investigate tooling parameters and finish machine a housing; (2) determine the coefficients of thermal expansion and thermal conductivity; (3) conduct a spiral bevel gear development test; (4) thermal map a transmission; (5) conduct a 50- hour overpower test; and (6) conduct a fail-safe test.
