Regular reflection of a strong shock wave by the surface of a wedge

Experimental investigations show that when allowance is made for the real properties of a gas it is possible to have a regime of regular reflection of a shock wave from the surface of a wedge in which the reflected shock wave is attached to the tip of the wedge. In the present paper, which uses perturbation theory in a form close to a modified small-parameter method, an approximate analytic solution is constructed to the problem of the interaction of a strong shock wave with the surface of a wedge for such a regime.
