Problems associated with lateral-control devices, leading-edge air intakes, and interference are briefly discussed, together with aerodynamic problems of application. There are links to the original airfoil source and dat file and the details page with polar diagrams for a range of Reynolds numbers. Click on an airfoil image to display a larger preview picture. Available data on high-lift devices are presented. Airfoil database search (Symmetrical) Search the 1638 airfoils available in the databases filtering by name, thickness and camber. Your Reynold number range is 50,000 to 1,000,000. Included below are coordinates for approximately 1,600 airfoils (Version 2.0). Airfoil Tools Search 1638 airfoils Tweet. NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. The report includes an analysis of the lift, drag, pitching-moment, and critical-speed characteristics of the airfoils, together with a discussion of the effects of surface conditions. Details of airfoil (aerofoil)(naca4415-il) NACA 4415 NACA 4415 airfoil. Detail data necessary for the application of the airfoils to wing design are presented in supplementary figures placed at the end of the paper. The general methods used to derive the basic thickness forms for NACA 6 and 7-series airfoils together with their corresponding pressure distributions are presented. New data are presented that permit the rapid calculation of the approximate pressure distributions for the older NACA four-digit and five-digit airfoils by the same methods used for the NACA 6-series airfoils. Summary of Airfoil Data The historical development of NACA airfoils is briefly reviewed.
