Abstract:

This report presents Sound Exposure Level SEL vs distance curves for eight models of Army rotary-wing aircraft OH-58, AH-1G, UH-1M, UH1-1H, UH- 1B, CH-47B, CH-54, and TH-55 performing dynamic operations, and Equivalent Sound Level contours for the same aircraft in static operations. The dynamic operations consisted of level fly overs, ascents, descents, turns, taekoffs, and landings static operations included in-ground and out-of-ground effect hovers. Results are grouped according to model and type of operation and are suitable for use in manual or computerized programs for predicting noise impact from rotary-wing aircraft.
