Using these values, one can compute the coordinates of the entire airfoil using specific equations, (II)NACA Five-Digit Series: The NACA Five-Digit Series and the Four-Digit Series are quite similar as they use the same thickness forms, but the mean camber line is defined differently and the naming convention is a bit more complex. However, it may be that it is actually a standard NACA 6 digit airfoil that translated would be a NACA 64,1-415. The excellent Polish aerobatic glider Swift S-1 uses indeed a NACA 6-digit airfoil, the $64_1412$. •The geometry of many airfoil sections is uniquely defined by the NACA designation for the airfoil. NACA 6 DIGIT AIRFOILS Six digit series is an improvement over 1-series airfoils with emphasis on maximizing laminar flow. •As an example, consider the NACA four-digit wing sections, which are. 7 Finite Wings 366 5.

The aerofoil section nomenclature is given by National Advisory Committee on Aeronautics (NACA) as NACA 4 digit series, NACA 5 digit series, NACA 6 digit series etc. NACA Airfoil Wizard.

The 4-digit-modified-series airfoils are designated by a 4-digit num-ber followed by a dash and a 2-digit number (such as NACA 0012-63). For example, an airfoil of the NACA 4-digit series such as the NACA 2415 (to be read as 2 – 4 – 15) describes an airfoil with a camber of 0. 1015x4 ⌘, x 2[0,1]. To get a general overview of the various NACA airfoil series, and the 6-Series in particular, check out a previous question on that subject. Several NACA 4-digit airfoils are used in the optimization process. The trailing edge is defined similarly as the point of maximum curvature at the rear of the airfoil. p, the distance of maximum camber from the leading edge (as per cent of chord). Consider an aircraft intended to cruise so its NACA 6-series airfoil is at an AOA near 1° and its section lift coefficient is 0.
