Helicopter-Load Tension-Member Study

Abstract

The objectives of this program were to analyze technology applicable to tension members as it relates to the functional requirements of heavy outsized loads externally suspended from helicopters, and to develop a comprehensive design theory and conceptual designs for tension members which will provide a basis for future detail design, fabrication, and test programs. The tension-member concepts selected for study included wire rope, wire-rope belt, synthetic rope, synthetic tape, steel tape, roller chain, and jointed links. A weighted-parameter technique was used to begin evaluation of these candidate concepts, followed by an analysis of practical considerations with reference specifically to the 1972, 1975, and 1980 time frames.
