Helicopter Drive System Load Analysis
Abstract
To study the overtorque conditions of three Army helicopter types - the AH-1G, UH-1H, and OH-6A - and the potential effect of such conditions on the maintenance procedures and design criteria for these helicopters was the prime objective of the reported research. To this end, approximately 755 hours of previously documented multichannel oscillogram data, recorded under combat conditions in the Vietnam theater, were reprocessed and reanalyzed to investigate the extent and significance of engine and transmission operations that exceeded specific torque pressure limits for each helicopter type.
