Summary:

The reduction in drag of an airfoil when the air stream is oscillating is called the Katzmayr effect. This effect was first described by Dr. Katzmayr. Confirming experiments have been made by Toussaint, Kerneir and Girault, and are given in a report translated by the National Advisory Committee fro Aeronautics in Technical Note No. 202 (Reference 2). That report confirms Katzmayr's results, yet contains no explanation or reason why an oscillating wind should reduce the airfoil drag. The purpose of this note is to offer a simple explanation of the cause of the Katzmayr effect.
