The report presents the results of an investigation of the fatigue strength of structural lugs. Design charts were formulated for fatigue-loaded steel and titanium lugs containing interference-fit liners. These lugs are representative of design practice in highly loaded aircraft applications, particularly that found in helicopter blade attaching systems. A primary element in the analytical study was a two-dimensional structural analysis of lug configurations. The designs are considered to be particularly applicable to helicopter rotor and control systems. (Author)
