3.14.1 Introduction

This class computes the thermodynamic properties of compressible gas flow over a wedge for a calorically perfect gas, as described by [naca1135]. It computes the following properties given the specific heat ratio γ and any of the up- or downstream mach number plus any of the other properties. After calling any of the evaluation functions the following properties will be available, where the subscript 1,2  refers to upstream and downstream, respectively;

The following properties are computed:
