Cars Īn inverted Clark Y airfoil was used on the spoilers of the Dodge Charger Daytona and Plymouth Superbird. Inexperienced modellers are more readily able to build model aircraft which provide a good flight performance with benign stalling characteristics. The Clark Y is appealing for its near-flat lower surface, which aids in the construction of wings on plans mounted on a flat construction board. Applications on model aircraft is very wide, ranging from free-flight gliders through to multi-engined radio control scale models. The Clark Y has found favor for the construction of model aircraft, thanks to the flight performance that the section offers at medium Reynolds number airflows. The paper studies background of different airfoil sections such as NACA0012, NACA0015, NACA4412, CLARK Y. The Clark Y was chosen as its flat bottom worked well with the design goal of a low radar cross-section.

The profile was designed in 1922 by Virginius E.

The Northrop Tacit Blue stealth technology demonstrator aircraft also used a Clark Y. The sentative of the best airfoils at present available for Clark Y airfoil was tested with 3 widths of ordinary flap, use on conventional airplanes. 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. Louis are two of the better known aircraft using the Clark Y profile, while the Ilyushin Il-2 and Hawker Hurricane are examples of mass-produced users of the Clark YH. You are encouraged to add airfoil coordinates to this database. 6 Turbulator spar stock, 1/8 x 3/16 x 24 in.The Clark YH airfoil is similar but with a reflexed (turned up) trailing edge producing a more positive pitching moment reducing the horizontal tail load required to trim an aircraft.2 Leading edge stock, 1/4 square x 24 in.

Clarks eventful career, the various aircraft that he designed and the many applications of his most famous creation are reviewed. The slotted Clark Y airfoils tested are shown in fig-ures 2 and 3. Combine multiple wing kits to produce higher aspect ratio wings (glider application) or clip the base wing for low aspect ratio applications. Clark was 1920's IIRC - some of those foils were the 'base' designs that NACA worked with. A Clark Y-14 airfoil, which is used in this demonstration, has a thickness of 14 and is flat on the lower surface from 30 of chord length to the back. He designed many aircraft and served in several important military and industry positions both during and after the First World War. Airfoil: CLARK Y AIRFOIL (clarky-il) Reynolds number: 100,000.
