Aircraft parts
A typical fixed-wing aircraft can be divided into the following major parts:
A long cylinder, called a fuselage, usually with tapered or rounded ends to make its shape aerodynamically smooth. The fuselage carries the human flight crew if the aircraft is piloted, the passengers if the aircraft is a passenger aircraft, other cargo or payload, and engines and/or fuel if the aircraft is so equipped. The pilots, who are members of the flight crew, operate the aircraft from a cockpit located at the front or top of the fuselage and equipped with windows, controls, and instruments. Passengers and cargo occupy the remaining available space in the fuselage. Some aircraft may have two fuselages, or additional pods or booms.
A pair of long, narrow, flat, nearly horizontal wings, with an airfoil cross-section shape, used to generate aerodynamic lifting force to support the aircraft in flight by deflecting air downward as the aircraft moves forward. The wings are typically symmetrical about the plane of symmetry (for symmetrical aircraft), and are attached to the fuselage roughly at its midpoint in most cases. The wings also stabilize the aircraft about its roll axis and control its rotation about that axis.
A small wing mounted vertically at the top rear of the fuselage, called a vertical stabilizer. The vertical stabilizer is used to stabilize the aircraft about its yaw axis (the axis in which the aircraft turns from side to side) and to control its rotation along that axis. Some aircraft have multiple vertical stabilizers.
A pair of small horizontal wings used mainly to stabilize the aircraft about its pitch axis (the axis around which the aircraft tilts upward or downward). The horizontal stabilizers are symmetrical and usually mounted near the rear of the fuselage, or at the top of the vertical stabilizer.
One or more aircraft engines, propulsion units that provide thrust to push the aircraft forward through the air. The engine is optional in the case of gliders that are not motor gliders. The most common propulsion units are propellers, powered by reciprocating or turbine engines, and jet engines, which provide thrust directly from the engine and usually also from a large fan mounted within the engine. When the number of engines is even, they are distributed symmetrically about the roll axis of the aircraft, which lies along the plane of symmetry (for symmetrical aircraft); when the number is odd, the odd engine is usually mounted along the centerline of the fuselage.
Landing gear, a set of wheels, skids, or floats (depending on the intended landing surface for the aircraft) that support the aircraft while it is on the ground.
