An interchangeable 5° or 6° wedge was mounted downstream of the first wedge to produce the second incident shock wave.

WebWhen supersonic flow goes over a diamond shaped aerofoil it creates 2 different types of shockwaves, Oblique shock waves and Expansions waves. Oblique shock waves are created when supersonic flow hits sharp pointed object, like a diamond shaped aerofoil. Expansion waves are waves that expand the medium through which they are transmitted.
