Wacko is an aerodynamics applet which calculates the coefficient of lift and drag and the pressure ratios on a quadrilateral airfoil. The inputs are checked before the main calculations are done. A bisection method is used to find the shock angle and the downstream Mach number on a Prandtl-Meyer expansion. Then the isentropic pressure ratio between two points are calculated using the Mach numbers. This applet was originally designed for a graduate high speed aerodynamics class project.

Wacko Supersonic Fluid Mechanics Applet. Requires Java to run.May not work on IE.

Future Work


This applet is named after one of the lead characters from the Animaniacs.
