Description
Summary:For the continued study of Army helicopter operations, a multichannel operational usage data program was conducted on two UH-1H helicopters flying assorted missions in the arctic environment from December 1972 to April 1973. During this period, 88 hours of valid in-flight data were recorded and processed for each of 15 time-related parameters. These parameters were selected to reflect the operational usage of the helicopters. Two techniques, the Four Mission Segment and the Flight Condition Recognition (FCR) methods, were used in processing and analyzing the data. The ultimate objective was to improve the fatigue analyst's understanding of the operational flight spectrum of U.S. Army helicopters and its effect in defining reliable design criteria for helicopters.
