Abstract:

A study of applications of filamentary composite materials to aircraft fuselage structure was performed. General design criteria were established and material studies conducted using the 727-200 forebody as the primary structural component. Three design approaches to the use of composites were investigated concept 1, uniaxial reinforcement of metal structure concept 2, uniaxial and biaxial reinforcement of metal structure and concept 3, an all- composite design. Materials application studies for all three concepts were conducted on fuselage shell panels, keel beam, floor beams, floor panels, body frames, fail-safe straps, and window frames. Cost benefit studies were conducted and developmental program costs estimated, also for all three concepts. On the basis of weight savings, cost effectiveness, developmental program costs, and potential for early application on commercial aircraft, the concept 1 design is recommended for a 5-year flight service evaluation program.
