Abstract:
1. A method operable to improve pressure recovery and distortion of an inlet, comprising: providing a first fluid flow to at least one primary jet vortex generator, wherein the at least one primary jet vortex generator injects fluid at a first injection rate into a boundary layer of a primary fluid flow within the inlet; providing a second fluid flow to at least one secondary jet vortex generator wherein the at least one secondary jet vortex generator injects inject fluid at a second injection rate into the boundary layer of the primary fluid flow within the inlet, and wherein the fluid injected at the first injection rate and second injection rate are operable to induce secondary flow structure(s) within the boundary layer; and redistributing a ratio of the first injection rate and second injection rate to improve pressure recovery and distortion of the inlet when at least one particular engine condition exists; wherein redistributing the first injection rate and second injection rate comprises adjusting a ratio of a first pressure within a first manifold and a second pressure within a second manifold, wherein the first manifold provides the first fluid flow to the at least one primary jet vortex generator and the second manifold provides the second fluid flow to the at least one secondary j et vortex generator.
