-Ferguson curves
Abstract
Ferguson’s curves are widely used in airfoil design. We present a kind of Ferguson’s curves with a shape parameter by integrating the classical Ferguson’s curves with the q -derivatives, called q -Ferguson curves. This kind of curves not only preserves the interpolation properties of classical Ferguson’s curves but also has a shape parameter which provides a freedom variable to construct the desired curves satisfying the interpolation or length constraint.
