The addition of standard leading-edge roughness causes the lift-curve slope of the newer sections to decrease with increasing airfoil thickness ratio. airfoil theory predictions for the pressure distribution on an NACA 4410 airfoil at 2°. The position of the aerodynamic center and the lift-curve slope of smooth NACA 6-series sections. Lift and pitching-moment characteristics of an NACA 0006 airfoil are presented for various deflections of a 0.15-chord leading-edge flap and a 0. ![]() What airfoil is used on the fill in the blank airplane Go here: The Incomplete Guide to Airfoil Usage (by David Lednicer). If you dont find the NACA section that you want, there are some NACA airfoil generation codes here, e.g. The quarter-chord pitching-moment coefficients and angles of zero lift of NACA 6A-series airfoil sections are slightly more negative than those of corresponding NACA 6-series airfoil sections. The only airfoil coordinates that I have are listed on the UIUC Airfoil Data Site. The name of the airfoil will also be automatically updated according to convention. An analysis of these results, which were obtained at Reynolds numbers of 3 x 10(exp 6), 6 x 10(exp 6), and 9 x 10(exp 6), indicates that the section minimum drag and maximum lift characteristics of comparable NACA 6-series and 6A-series airfoil sections are essentially the same. The NACA 5-Series airfoil is automatically generated from the ideal lift coefficient, maximum camber location, and thickness to chord ratio parameters by the functions that define the shape. The experimental results of a two dimensional wind tunnel investigation of the aerodynamic characteristics of five NACA 64A-series airfoil sections and two NACA 63A-series airfoil sections are presented. They are very effective in case of low Reynolds number flows. Tubercle Leading Edge (TLE) effectively reduces the separation bubble size and helps in delaying stall. ![]() Also presented are data for a mean line designed to maintain straight sides on the cambered sections. The Humpback whale tubercles have been studied for more than a decade. The flow over a NACA 0012 airfoil oscillating in pitch was experimentally investigated at a Reynolds number of 2.5×106, a Mach number of 0. Theoretical data are presented for NACA 6A-series basic thickness forms having the position of minimum pressure at 30-, 40-, and 50-percent chord and with thickness ratios varying from 6 percent to 15 percent.

Theoretical and Experimental Data for a Number of NACA 6A-Series Airfoil Sections The NACA 6A-series airfoil sections were designed to eliminate the trailing-edge cusp which is characteristic of the NACA 6-series sections.
