Experiments were conducted to determine the nature of the deceleration of supersonic airstreams in straight passages of constant cross sectional area. The magnitude of the losses associated with the recovery of kinetic energy was established, Schlieren observations were made of the field of flow in the passage and the influence of passage length, Mach Number and effective Reynolds Number on maximum obtainable pressure rise were investigated.
