An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft.

Aircraft fabric covering

Aircraft fabric covering is a term used for both the material used and the process of covering aircraft open structures.

Aircraft fairing

An aircraft fairing is a structure whose primary function is to produce a smooth outline and reduce drag.

Angle of incidence (aerodynamics)

On fixed-wing aircraft, the angle of incidence (sometimes referred to as the mounting angle) is the angle between the chord line of the wing where the wing is mounted to the fuselage, and a reference axis along the fuselage (often the direction of minimum drag, or where applicable, the longitudinal axis).

Argus As 8

The Argus As 8 was a four-cylinder, air-cooled, inverted inline aircraft engine produced in Germany by Argus Motoren in the 1930s.

Camber (aerodynamics)

In aeronautics and aeronautical engineering, camber is the asymmetry between the two acting surfaces of an aerofoil, with the top surface of a wing (or correspondingly the front surface of a propeller blade) commonly being more convex (positive camber).
