The Kline–Fogleman airfoil, sometimes known as the KF airfoil, is a basic airfoil with one or more steps along the length of the wing. In the early 1960s, a series of KF airfoils were constructed and used in paper planes for the first time. Because of their simple design, high climb and wind resistance, they are now widely used in remotely ...
It was advertised in TV commercials. It was a small delta-wing glider, maybe 6 or 7 inches long, made out of a sheet of yellow plastic folded to create a Kline-Fogleman airfoil with a step on the underside surface of the wing, and it had a rubber nose weight for balance and a plastic tab sticking down from the belly to hold while throwing it.
An airfoil (American English) or aerofoil (British English) is a streamlined body that is capable of generating significantly more lift than drag. [1] Wings, sails and propeller blades are examples of airfoils. Foils of similar function designed with water as the working fluid are called hydrofoils.

At best, we can say that the airfoils drawn in the Kline-Fogelman article are in a state of "perpetual flaps-extended" mode. Nimur ( talk ) 18:50, 16 August 2011 (UTC) [ reply ] Kline Fogelman airfoils are used only on small scale RC aircraft where the requirements are different then on full size.
