Introduction

3.11.1 Introduction

This function group computes the thermodynamic properties of an oblique shock wave given either a mach number and the surface deflection or wave angle or based upon both the wave and deflection surface angles, using algorithms as described in [usafv1], [naca1135] and [NASA187173].

Oblique Shock Waves are classified by the following properties, where the subscript $1,2$ refers to upstream and downstream, respectively. The normal mach numbers $M1n$ and $M2n$ represent the mach numbers through the shock front as by the normal shock wave equations.

The following properties will be available:
