Abstract:

The report presents the results of dynamic load tests performed on a turbine powered helicopter transmission which incorporates a roller gear drive unit as the main reduction stage. The primary purpose of this program was to conduct a 200-hour endurance test at 100 design speed and at a load spectrum equivalent to military helicopter usage.
