Efficiency Testing of a Helicopter Transmission Planetary Reduction Stage.

Abstract

A parametric study of the efficiency of a 310-kW (420-hp) helicopter transmission planetary test section (four-planets) was performed. The purpose was to determine the planetary contribution to the overall transmission power loss. Test parameters varied were oil flow rate, oil inlet temperature, lubricant type, shaft speed, and applied torque. The measured efficiency over all the test variables ranged from 99.44 to 99.75 percent. These experiment results were compared with other experimental and computational results.
