3000-HP Roller Gear Transmission Development Program. Volume VI. Reliability and Maintainability Report

Abstract

This report presents a summary of the testing conducted during the development of a 3000-HP Roller Gear Transmission. During this program a helicopter transmission using a 19.85 reduction ratio roller gear transmission was designed, manufactured, and subjected to extensive testing. A reliability analysis shows that a fully developed roller gear transmission offers comparable reliability to a conventional two-stage planetary unit. However, relating the development testing of the roller gear transmission to project the reliability is premature at this stage. The analysis does show that on-condition maintenance of the roller gear transmission is feasible. A summary of the testing and development of the roller gear transmission is included. Detailed reports on the design, manufacture, and bench and aircraft testing have been published separately.
