An experimental study of the response to downstream pressure perturbations of transonic shocks in a parallel walled duct has been conducted. Tests have been carried out for normal shock strengths of M ∞ = 1.4 and 1.5 with pressure perturbation frequencies in the range 16–90 Hz. The measurement techn...
