초록

An air intake for a supersonic air-breathing flight vehicle introduces or injects fluid in order to create predetermined regions of separated flow and an attendant fluid shear layer. This shear layer forms an aerodynamic boundary for the capture flow with a profile determined and optimised by appropriate injection of fluid. The aerodynamic boundary so generated replaces mechanically moveable solid surfaces used to vary the geometry of prior-art intakes. Use of an introduced or injected fluid can provide an advantage of a variable geometry, but with reduc...

1. A method of controlling a location of shock waves generated at a leading edge of an engine intake of an engine in a powerplant of a supersonic vehicle, the engine intake comprising a surface providing the leading edge and a cowl having a cowl lip downstream of the leading edge, so that the shock wave extends in an optimum orientation relative to the cowl lip, the method comprising: downstream of the leading edge and upstream of the cowl lip, injecting air into an air flow captured by the air-intake, the air being injected through or adjacent the surfa...
