The NACA airfoil series The early NACA airfoil series, the 4-digit, 5-digit, and modified 4-/5-digit, were generated using analytical equations that describe the camber (curvature) of the mean-line (geometric centerline) of the airfoil section as well as the section's thickness distribution along the length of the airfoil. NACA 0015 For aerobatic airplanes, NACA 0015, it also has different thicknesses, it's a great symmetrical airfoil. The results for the NACA 4412 airfoil optimized in ground effect are compared with. The lower side of the airfoil is at the three measured. For sailplanes Drela airfoils are popular, for larger gliders the AG2x series (AG24 -AG27) are common.

Obviously there are thousands of airfoils out there, so these are just examples of the types. The 15 indicates that the airfoil has a 15% thickness to chord length ratio: it is 15% as thick as it is long are four design points shown for. It's a glider so it won't require high angle of attack, NACA 4 series more efficient, as well as other non NACA airfoils that look similar A glider also always stay in non critical subsonic air flow, so filter it that maximum chamber and thickness are in front. Instead it uses a NACA 0014-1. This NACA airfoil series is controlled by 4 digits e. . wisconsin craigslist pets
