Clark-Y

Clark-Y is the name of a particular aerofoil profile, widely used in general purpose aircraft designs, and much studied in aerodynamics over the years. The profile was designed in 1922 by Virginius E. Clark. The airfoil has a thickness of 11.7 percent and is flat on the lower surface from 30 percent of chord back. The flat bottom simplifies angle measurements on propellors, and makes for easy construction of wings on a flat surface.

For many applications the Clark-Y has never been bettered, it gives good overall performance in respect of its Lift-to-drag ratio, and has gentle and relatively benign stall characteristics. The Lockheed Vega is one example of the Clark-Y in practice.

Aerodynamics: Aerodynamics is a branch of fluid dynamics concerned with the study of gas flows, first analysed by George Cayley in the 1800s. The solution of an aerodynamic problem normally involves calculating for various properties of the flow, such as velocity, pressure, density, and temperature, as a functio...
