This calculator was created by Evan Warner while a student in AOE 3164 Aerothermodynamics and Propulsion at Virginia Tech.

The calculator concept was inspired by the Compressible Aerodynamics Calculator created by Prof. William Devenport.

Documentation of the theory, assumptions, and formulae implemented in the calculator is available to follow:
