EVALUATION OF RAIN-EROSION-RESISTANT MATERIALS TO PROTECT THE HH-43B/F HELICOPTER ROTOR

Abstract

The report describes the tests of various materials to determine a suitable protective covering for the HH-43B/F helicopter servo-flap leading edge when operating in rain. Nineteen materials were tested and compared on a rain erosion spray rig in the electric motor whirl stand facility at WPAFB Ohio. Impact velocity varied from 330 to 730 ft per second. A description of the facility, test procedures, results and recommendations is presented. Photographs of the spray rig and test specimens are also included.
