Clark Y is the name of a particular airfoil 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 using thickness distribution of the German-developed Goettingen 398 airfoil. [ 1 ]
Various airfoil generation systems are also used. An example of a general purpose airfoil that finds wide application, and pre–dates the NACA system, is the Clark-Y. Today, airfoils can be designed for specific functions by the use of computer programs.
The General Aviation GA-43 was a single engine low-wing monoplane airliner produced in small numbers in the United States in the mid-1930s, also known as the Pilgrim 150, Fairchild 150, and sometimes but erroneously as the Clark GA-43 for the designer, Virginius E. Clark who was also responsible for the Clark Y airfoil section used.
The lower wing had a Clark-Y airfoil, a structure of wood with plywood planking. The upper wing, also constructed of wood with a Herrick M-7-II airfoil, had double planking. The symmetrical airfoil, with a curved top and flat bottom, had a depth of 1.20 m at the center, tapering to 0.60 m at the wingtips.
Virginius Evans Clark (February 27, 1886 – January 30, 1948) was an officer in the United States Army, a military aviation pioneer, and a World War I engineer. Clark designed the 1922 Clark Y airfoil used by many early aircraft.
In 1921, Colonel Virginius Clark, chief designer of the Dayton-Wright Company, designed the Chummy sporting biplane. [1] The airframe was advanced in its use of the new Clark Y thick-section airfoil and a welded fuselage framework of chrome-molybdenum steel tubing. A departure from the all-wood structures found in other trainers, the structure ...
Staib flew his aircraft in airshows with the title "The Diamond Wizard". [2] The LB-4 is a high-wing, uncovered welded steel tube fuselage, single seat twin-engine tricycle gear aircraft. It was registered by the FAA in 1966, and was considered at the time to be the world's smallest twin engine aircraft. The wing ribs were a shortened pattern ...
DSK Airmotive Hawk. The DSK Airmotive DSK-1 Hawk was an unusual homebuilt aircraft designed in the United States in the early 1970s. While the design itself was utterly conventional - a single-seat low-wing cantilever monoplane with fixed tricycle undercarriage - its method of construction was not, since the DSK-1 Hawk used a surplus 200 US Gal ...
