This says the Joukowski transformation is 1-to-1 in any region that doesn’t contain both z and 1/z. This is the case for the interior or exterior of. The Joukowski transformation is an analytic function of a complex variable that maps a circle in the plane to an airfoil shape in the plane. A simple way of modelling the cross section of an airfoil or aerofoil is to transform a circle in the Argand diagram using the Joukowski mapping.

The solution to potential flow around a circular cylinder is analytic and well known. Why is the radius trabsformation calculated such that the circle passes through the point 1,0 like: The advantage of this latter airfoil is that the sides of its tailing edge form an angle of radians, orwhich is more realistic than the angle of of the traditional Joukowski airfoil.
Exercises for Section Refer to Figure The sharp trailing edge of the airfoil is obtained by forcing the circle to go through the critical point at. Hassan Hassan view profile.

Details If the center of the circle is at the origin, the image is not an airfoil but a line segment. Otherwise lines through the origin are mapped to hyperbolas with equation. This transform is also called the Joukowsky transformationthe Joukowski transformthe Zhukovsky transform and other variations. It’s obviously calculated as a potential flow and show an approximation to the Kutta-Joukowski Lift.
Details Details of potential flow over a Joukowski airfoil and the background material needed to understand this problem are discussed in a collection of documents CDF files available at [1].

This is the case for the interior or exterior of the unit circle, or of the upper or lower half planes. For a fixed value dyincreasing the parameter dx will fatten out the airfoil.

The Joukowsky transformation can map the interior or exterior of a circle a topological disk to the exterior of an ellipse.
