Fuselage

The component of an aircraft that provides the payload containment and the structural connection for the wing and the empennage (tail assembly). The fuselage and the wing are major structural components of an aircraft. The fuselage is the mounting structure for the horizontal and tail surfaces that provides stability as well as the means of introducing pitch and yaw control to the aircraft. For some aircraft like fighter and private aircraft, the fuselage houses the engine or engines. The nose or tail gear and the main landing gear are often attached to the fuselage structure.

The history of the construction of aircraft fuselages has evolved through the early wood truss structural arrangements to the current metal semi-monocoque shell structures. A majority of aircraft fuselages are fabricated from aluminum alloys and are produced by a process of automatic machining of the skins and stringers (see illustration), with much of the assembly being done by automatic drilling, countersinking, and fastener installation. In some areas, adhesive bonding is used as a means of attaching doublers to reinforce skin panels. In many of the high-performance aircraft, such as fighters and bombers, extensive use is made of titanium and high-strength steel. See Airframe

Fuselage 

in aviation, the body of an aircraft, used to accommodate the crew, passengers, cargo, and equipment; it ties together the wing, empennage, and sometimes the landing gear and power plant. The principal structural elements are a frame and a skin. In truss fuselages, the frame is a three-dimensional truss, and the skin serves to give the fuselage a streamlined shape. In shell-type fuselages, the framework is created by longitudinal elements (longerons and stringers) and transverse elements (ribs); the skin, which provides stiffening, and the frame both take up the load. Composite fuselages may combine a forward section of the truss-type with a shell-type tail, or vice versa.

Supersonic aircraft have the nose section sharply pointed for improved aerodynamics. In some aircraft the empennage is mounted on special beams; in such cases the fuselage is called a gondola. The fuselages of seaplanes are made in the form of a marine hull.
