An investigation of hypersonic boundary‐layer flow along a flat plate is being presented. The high Mach number investigated calls for the consideration of the chemical reactions and the change in thermodynamical properties for temperatures up to T = 6000 K. For the current investigation a test case at M = 20 and the atmospheric conditions at an altitude of H = 50 Km is chosen. The differences to the ideal‐gas result is demonstrated.
