Transmission Research Activities at NASA Lewis Research Center

Abstract

The NASA Lewis Research Center and The U.S. Army Aviation Systems Command (AVSCOM) are involved in a joint research program to advance the technology of rotorcraft transmissions. The program consists of analytical and experimental efforts to achieve the overall goals of reducing transmission weight and noise, while increasing life and reliability. The work includes in- house studies and tests, university grants, industry contracts, and joint programs with other military organizations. This paper highlights recent activities in the areas of transmission and related component research. Current areas include specific technologies in support of military rotary wing aviation, gearing technology, transmission noise reduction studies, a recent interest in gearbox diagnostics, and advanced transmission system studies. Results of recent activities are presented along with near term research plans. Keywords: Transmissions, Gears, Noise, Diagnostics.
