A fixed-wing aircraft may have more than one wing plane, stacked one above another: Biplane: two wing planes of similar size, stacked one above the other.The biplane is inherently lighter and stronger than a monoplane and was the most common configuration until the 1930s.
The variable-sweep wing transforms between an efficient straight configuration for takeoff and landing, to a low-drag swept configuration for high-speed flight. Other forms of variable planform have been flown, but none have gone beyond the research stage. The swept wing is a straight wing swept backward or forwards.
Aerofoil nomenclature showing chord line Chord line of a turbine aerofoil section. Chords on a swept-wing. In aeronautics, the chord is an imaginary straight line segment joining the leading edge and trailing edge of an aerofoil cross section parallel to the direction of the airflow.
The concept of the flying wing was born on 16 February 1876 when French engineers Alphonse Pénaud and Paul Gauchot filed a patent for an aero-plane or flying aircraft [5] powered by two propellers and with all the characteristics of a flying wing as we know it today. [6] Tailless aircraft have been experimented with since the earliest attempts ...
Wing loading is a useful measure of the stalling speed of an aircraft. Wings generate lift owing to the motion of air around the wing. Larger wings move more air, so an aircraft with a large wing area relative to its mass (i.e., low wing loading) will have a lower stalling speed.
A straight leading edge may be swept or unswept, the latter meaning that it is perpendicular to the longitudinal axis of the aircraft. As wing sweep is conventionally measured at the 25% chord line [ 3 ] an unswept wing may have a swept or tapered leading edge.
A blended-wing plane would have a much wider cabin than a traditional tube-and-wing design, meaning the rows could be more than a dozen people long.
As the angle of attack of a fixed-wing aircraft increases, separation of the airflow from the upper surface of the wing becomes more pronounced, leading to a reduction in the rate of increase of the lift coefficient. The figure shows a typical curve for a cambered straight wing. Cambered airfoils are curved such that they generate some lift at ...
