For detail information you can refer to the original paper by Brenda Kulfan: So far: I have generated equation for NACA 4 and 5 series airfoil based on the input series number from the user. I have the main program that is using airfoil geometry to calculate pressure distribution and use the pressure distribution later on in other equations. You can also easily add the order of CST by simply adding additional weight value on wl or wu inputs. This is the program Im trying to create (very new to Matlab). Symmetrical airfoils NACA 4 digit airfoils NACA 5 digit airfoils NACA 6 series airfoils Airfoils A to Z. The latter will gives coordinates that resembles the shape of Clark-Y airfoil. Airfoil data Lift/drag polars Generated airfoil shapes Searches. Where the output is a set of x and y coordinates of CST generated airfoil.Īs a demonstration, you can try the following:ĬST_airfoil(, ,0,400)

As suggested you can also normalize each segment's normal and then average as such. of course you can normalize the result if you want normals of equal length. The input to CST_airfoil.m is the following: nx will contain x-component of your normal and ny will contain y-component of your normal.
#MATLAB AIRFOIL GENERATOR CODE#
The code is easy to use and also very easy to be modified for your own needs. CST build the airfoil by summing the individual contribution of its basis function that is built by Bernstein Polynomial. CST with low order polynomial is also suitable for airfoil preliminary design and optimization purpose since it only needs few parameters to give specific shape of airfoil. CST method is a powerful parameterization method because of its simplicity, robustness, and its ability to be generalized into various possible shapes of aerodynamic bodies.
