The fuselage has also elements perpendicular to the skin that support it and help keep its shape. The semi-monocoque construction, which is virtually standard in all modern aircraft, consists of a stressed skin with added stringers to prevent buckling, attached to hoop-shaped frames. In transport aircraft, the majority of the fuselage is cylindrical or near-cylindrical, with tapered nose and tail sections. © Sovxx / Wikimedia Commons / CC-BY-SA-3.0. At the same time, the structural weight must be kept to a minimum.įigure 4.12: Semimonocoque Airbus A340 rear fuselage, seen from inside. The structural strength and stiffness of the fuselage must be high enough to withstand these loads. It must be able to resist bending moments (caused by weight and lift from the tail), torsional loads (caused by fin and rudder), and cabin pressurization. The fuselage should carry the payload, and is the main body to which all parts are connected.
