The Kline–Fogleman airfoil or KF airfoil is a simple airfoil design with single or multiple steps along the length of the wing. It was originally devised in the 1960s for paper airplanes. In the 21st century the KF airfoil has found renewed interest among hobbyist builders of radio-controlled aircraft, due to its simplicity of construction. [1]
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.
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.
Camber (aerodynamics) In aeronautics and aeronautical engineering, camber is the asymmetry between the two acting surfaces of an airfoil, with the top surface of a wing (or correspondingly the front surface of a propeller blade) commonly being more convex (positive camber). An airfoil that is not cambered is called a symmetric airfoil.

Douglas D-558-2 Skyrocket. The Douglas Skystreak (D-558-1 or D-558-I) was an American single-engine jet research aircraft of the 1940s. It was designed in 1945 by the Douglas Aircraft Company for the U.S. Navy Bureau of Aeronautics, in conjunction with the National Advisory Committee for Aeronautics (NACA). The Skystreak was a turbojet -powered ...
