ABSTRACT:
Design and construction of a composite material airplane having a high aspect-ratio wing and a horizontal double-lobe fuselage cross-section for cargo and/or passenger accommodations. The fuselage comprises a double-lobe shell of contoured honeycomb core composite panels and an interior vertical plane centerline web forming a divider between the lobes. Piano-hinge type joints are utilized for multi-panel junctures to provide uniform load distribution across the junctures. The piano-hinge juncture utilizes hinge lugs which are dimensioned to interface sequentially along the hinge axis, and the hinge lugs are interconnected by a tubular hinge pin.
