Details of airfoil (aerofoil)(e421-il) EPPLER 421 AIRFOIL Eppler E421 high lift airfoil. Heard rumors he had the Patrol at a STOL contest recently. The 4 series has lower Reynolds #s than the 6s so don't know how it would compare side-by-side with a Cub of similar weight/power. Bob Barrows chose the Riblett GA35-413.5 for the Patrol which worked out pretty well from the reports I've read. I'm using the Riblett GA30A613.5 on my little bush plane project. I have Compufoil loaded in my computer and with it I can overlay two airfoils on top of the main airfoil.

The Riblett GA30A613.5 should be just a tad bit better. What airfoil is used on the fill in the blank airplane Go. If you dont find the NACA section that you want, there are some NACA airfoil generation codes here, e.g. The USA35B is a good airfoil, no question about it. Where can I get coordinates for NACA xxxx or some other airfoil The only airfoil coordinates that I have are listed on the UIUC Airfoil Data Site. I've read and utilized both and Riblett has his stuff wired. and it's a lot easier read than Abbott and Von Doenhoff's book: The Theory of Wing Sections. Furthermore, it enables the cruise performance and drag divergence Mach number to be predicted with only one simulation of the cruise point, which will greatly save the computational cost of optimizations.The EAA sells a book (about $20) called GA Airfoils written by Harry Riblett which is a very informative book that the average aviator should have no problem understanding. 961 airfoil Max thickness 9.3 at 20 chord Max camber 4.6 at 40 chord Source UIUC Airfoil Coordinates Database (isa962-il) I.S.A. 961: Airfoil details Send to airfoil plotter Add to comparison Lednicer format dat file Selig format dat file Source dat file: I.S.A. It indicates that the drag divergence Mach number can be increased by obtaining a shock wave that is further upstream in the detailed design. Source UIUC Airfoil Coordinates Database (isa961-il) I.S.A. ![]() Compared with Korn's equation, the discovered correlation reduces the maximum prediction error by approximately 40%. ![]() A new linear correlation is discovered and validated by existed airfoil databases. Correlation screening and multivariate regression are carried out to discover knowledge about the airfoil drag divergence Mach number and pressure distribution features. The discussion is organized according to the application (i.e., free flight model airfoils are first discussed, then F3B airfoils and so on for each category). This paper designs a supercritical airfoil database that covers the typical free stream Mach number, angle of attack, lift coefficient, and geometry of modern transonic commercial aircraft. In Chapter 3, a discussion of all the airfoils is given first then the figures (airfoil plots and performance data) are presented in Chapter 4. However, it neither reveals the key factors of fluid features on the drag divergence nor contributes to the detailed design. ![]() It is very helpful in the aircraft initial design. Details of airfoil (aerofoil)(n63210-il) NACA 63-210 AIRFOIL NACA 63-210 airfoil. For example, Korn's equation predicts the airfoil drag divergence Mach number using the airfoil maximum thickness and the lift coefficient. Aerodynamic rules and knowledge are often obtained through theoretical research and experiments, which have contributed greatly to aircraft design.
