ABSTRACT:
A supersonic inlet flow duct (10) is provided with a pivoting bleed stability door (34) and biasing spring (42). The door (34) opens under the influence of increased static fluid pressure behind a shock front (24) which is displaced forwardly by a downstream pressure perturbation. The opened door (34) diverts portions (31, 44) of the inlet duct flow stabilizing the shock front (24a) and downstream shock train (25) within the duct (10) until the perturbation subsides.
