Clark y. It has a flat lower surface, a high thickness ratio, and a gentle stall characteristic. 7% and a maximum camber of 3. 30, 1948. . See the dat file parser, the source database and the graph of the airfoil coordinates. The profile was designed in 1922 by Virginius E. This paper traces the life and times of Colonel Virginius Evans Clark and his most well known creation, the famous Clark Y airfoil. CLARK Y is a symmetric airfoil with a maximum thickness of 11. 4%. 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. Clark. Colonel Virginius Evans Clark, famous Signal Corps pioneer aeronautical engineer, consulting engineer of the Hughes Aircraft Company, died in Santa Monica hospital on Jan. Clark in 1922. With its predictable and gentle stall characteristics and flat bottom outline, the Clark Y airfoil is an ideal choice for sport RC model aircraft. Oct 25, 2011 ยท Clark Y is the name of an airfoil that is widely used in aircraft design. Clark Y is a specific airfoil profile developed by Virginius E. Despite that fact that he is today mainly remembered (if at all) for that one achievement, Clark was a many faceted and somewhat controversial aviation pioneer. Clark Y is a common airfoil profile for general purpose aircraft, designed in 1922 by Virginius E. It is used in aircraft design, model aircraft and stealth technology for its efficiency, stall characteristics and flat bottom. wewu ppir dop zjvba wsmjxx eqtd lfo xmu fmctp ycthwuh
