About
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.
Future Work
- Check for possible bug in findshockangle function.
- Fix bug in coefficients calculation.
- Create a class using parts of this for other Java programs.
- Redesign user interface.
Name
This applet is named after one of the lead characters from the Animaniacs.
