AER100 Lecture Notes - Lecture 1: Monocoque, Fuselage, Geodesic
Document Summary
Aer 100 lecture 1 : parts of an airplane: fuselage: main body of airplane, construction techniques, non-structural skin. Frame of metal or wood covered by fabric (later covered by metal: consists of longerons, trusses, and girders. Skin does not contribute: consists of members and braces, can be truss type or geodesic type, truss: rectangular shape with trusses forming triangles. Strong and simple to build, but heavy: usually square shape with much drag, geodesic: flat strip stringers are wound about the formers in opposite spiral directions, forming a basket-like appearance, complex and expensive, but low drag. "single-shell: consists of bulkheads, formers and stringers, usually only feasible in composite airplanes, all parts are made with monocoque construction. Skin must be thick and strong to carry all compressive and tensile loads. Semi-monocoque: consists of an internal skeleton and skin both carrying load, consists of frames (bulkheads) running vertically and longerons and/or stringers.
