They became the NACA 4-digit airfoils. The NACA 2412 is almost exactly the same as the Clark Y. Later, the 5-digit series was created from mathematical analysis. The 6-series so-called "laminar flow" sections took it even further, with airfoils very high lift/drag ratios, but only in a narrow AOA range.Analysis of an NACA - Global Journals Look at similar-to designs and start there. There are lots of free plans. Basic NACA airfoils are fine for starting but there are plenty of openly available empirical designs like the Clark Y that perform better.

Last update 6/4/2023 what's new. Frequently, the question arises as to what airfoil or airfoils were used in the wing design of a particular aircraft. Jane's All The World's Aircraft has been a good source of this information, but in many cases ... Jan 26, 2022 · If I were to want better than 2 significant digits of accuracy, I'd turn to someone that wins contests with his air foils on model gliders versus trying to use full-scale foils like NACA Laminar flow foils, NACA 4-digit, or even Clark-Y airfoils. This report presents the results of wind tunnel tests conducted to determine the aerodynamic characteristics of the Clark Y airfoil over a large range of Reynolds numbers. Three airfoils of aspect ratio 6 and with 4, 6, and 8 foot chords were tested at velocities between 25 and 118 miles per hour, and the characteristics were obtained for Reynolds numbers (based on the airfoil chord) in the ...Abstract: This note gives the aerodynamic characteristics of the N.A.C.A. 97, Clark Y, and N.A.C.A.-M6 airfoil sections as determined in the variable density wind tunnel al Langley Field, Virginia.
