Composite-Material Helicopter Rotor Hubs
Abstract
This report describes the development work for construction of helicopter rotor hubs from fibrous composite materials. The prototype hubs were designed to be structurally and functionally equivalent to the metallic hub used on the Sikorsky CH-54B HELICOPTER. The design is based on the principle of filament-wound tension loops in combination with laminated shear panels. The report contains a description of the design elements, of the structural analysis, of the construction methods, and of the experimental evaluation of rotor hubs subjected to static as well as cyclic loads. Design and construction problems are discussed, and the potential of the composite hub concept is outlined. (
