Cold Weather Evaluation of the 206-011-850-1 Tail Rotor Equipped with Elastomeric Flapping Bearings in Fairbanks, Alaska.

Abstract

A flight test evaluation was conducted at Ft. Wainwright, Fairbanks, Alaska for the purpose of determining the effect of cold ambient temperatures on the elastomeric bearings in the 640 main rotor and 206-011-850-1 tail rotor. The results of testing are contained in this report in tabular and graphic form. Oscillatory and mean loads exceeded both the infinite life load limits for the non-rotating control tubes and the hydraulic boost capability. (Author)
