![]() ![]() naca 5 digit airfoil explanation, The original reference for symmetrical airfoils must be: "Tests of six symmetrical airfoils in the variable density wind tunnel" NACA Technical Note No. Source Code: naca4_mpt.m, extracts the M, P and T parameters from a NACA 4 digit code. These sections had the same thickness distribution, but used a camberline with more curvature near the nose. NACA Airfoils Mean camber line Chord line Chord x=0 x=c Leading edge Trailing edge x z Definitions: Airfoil Geometry NACA Nomenclature NACA 2421 1st Digit: Maximum camber is 2% of 2D airfoil chord length, c (or 3D wing mean chord length, c). The NACA 5-Digit Airfoil This airfoil is an extension of the 4 digit series which provides additional camber lines. NACA 5 digit Airfoil Generator (Scripts) Publisher's description from Divahar Jayaraman "naca5gen.m" Generates the NACA 5 digit airfoil coordinates with desired no "naca5gen.m" Generates the NACA 5 digit airfoil coordinates with desired no. The AeroToolbox NACA 4-series calculator can be used to plot and extract airfoil coordinates for any NACA 4-series airfoil. ![]()
