Abstract—Though it is easier to model and create an airfoil profile in CAD environment using camber cloud of points, after the creation of vane profile it is very difficult to change the shape of profile for analysis or optimization purpose by using cloud of points. In this paper, we investigate and described the creation of airfoil profile in CAD (CATIA) environment using the control point of the camber profile. By means of changing the values of control points, the shape of the profile can be easily changed and also the design of the cambered airfoil was established without affecting the basic airfoil geometry. In this paper, the Quintic Reverse Engineering of Bezier curve formula was used to find the camber control points from the existing camber cloud of points.
