How does surface roughness including frost and flaking paint affect aerodynamics? In this note, I take a look at the physics and the drag and stall characteristics of frost and flaking paint. A flight test of two Cessna 172s indicates the surprisingly large relative drag increment of flaking paint.

Joukowski Transform
\(\) The Joukowski transform is a stunningly simple mathematical operation that converts a circle into an airfoil.
$$w=z+\frac{c^2}{z}$$
The beauty of the transform is that ideal fluid flow past a circle is described by a classic and well known set of terms.
I made a small visualization program that allows experimentation with a Joukowski airfoil in an ideal fluid flow environment. This is meant to illustrate conformal mapping to my GES 554 class and airfoil theory to AEM 614.
