520 ▼a The structure and dynamics of a shock train are studied experimentally using a direct-connect isolator model with a nominal inflow Mach number of 2.0. The experiments mimic the flow in high-speed air-breathing engines, where the shock train is r
520 ▼a Schlieren imaging is used to study the shock train oblique-to-normal transition as the pressure downstream of the isolator is increased. During this process, the shock system moves upstream where the approach conditions are different, as these q
520 ▼a The major contribution of this work is the development of a theory that explains why the shock train is inherently unsteady even with constant bulk inflow and outflow conditions. Cross-spectral analysis of pressure and shock position fluctuation
520 ▼a The inherent unsteadiness theory introduces several mechanisms that explain how perturbations influence the shock system. One mechanism links downstream disturbances to the isolator dynamics. To examine this further, oscillatory downstream forci
