A number of useful utilities and educational online tools have been developed, and are listed below. Please make use of these free internet services.

• JavaScript Calculator An almost useless utility, however it does demonstrate the use of JavaScript for form-element manipulations and the JavaScript math object.
• Mohr's Circle Solver A utility to compute the principal and directed stresses in an arbitrarily loaded structural element.
• Panel Code V1 Our original panel code, producing both graphical and tabular data for the pressure distribution about NACA 4 and 5 digit airfoils.
• Panel Code V2 An updated version of the old code, including over 1150 additional airfoils from the UIUC database, and offering improved graphics with streamlines, field pressure, velocity vectors and more.
• Transonic Small Disturbance Solver A utility for computing the transonic flow over thin airfoils or through nozzles. Plots the wall pressure as well as the Mach number distribution.
