초록

A system for reducing distortion at the aerodynamic interface plane of a boundary-layer-ingesting inlet using a combination of active and passive flow control devices is disclosed. Active flow control jets and vortex generating vanes are used in combination to reduce distortion across a range of inlet operating conditions. Together, the vortex generating vanes can reduce most of the inlet distortion and the active flow control jets can be used at a significantly reduced control jet mass flow rate to make sure the inlet distortion stays low as the inlet m...

청구항

The invention claimed is: 1. A boundary-layer-ingesting inlet comprising: a plurality of vortex generating vanes, and a plurality of active flow control jets, wherein said plurality of vortex generating vanes and said plurality of active flow control jets operatively achieve inlet distortion of a desired level. 2. The boundary-layer-ingesting inlet according to claim 1, wherein said plurality of active flow control jets operate in the range of 0% to about 0.5% of inlet mass flow. 3. The boundary-layer-ingesting inlet according to claim 1, wherein ...
