Airfoil->Spline->Smooth Matlab
 

Hello everyone, I´m working with Matlab to draw airfoils. I use splines to improve the visualization, but in the leading edge I have problems, I want to have a curve more smoother, like a circle in the leading edge.

Anybody knows other method to join the points of an airfoil?

Anybody knows a smooth method to use whit airfoils?

In the photo, you can see my problem. I use cubic spline (natural conditions).

Thank you, and sorry for my English.

I think you did something wrong in the spline....

Thank you FMDenaro for your answer. I have two splines, one for the upper surface and another for the lower surface. I can´t use an spline to join all the points.

why not? you define the law x=x(s), y=y(s) with s a natural parameter ...
