Abstract:

The free planet gear drive was applied to the requirements of the Medium-Range Utility Transport Helicopter. Design studies showed potential advantages for the free planet drive as compared to conventional planetary systems used hitherto. Recommendations were made that existing free planet hardware be further tested to better define load-carrying capability and system reliability.
