摘要

THRUST-REVERSER ASSEMBLIES THAT UTILIZE ACTIVE FLOW CONTROL AND SYSTEMS AND METHODS INCLUDING THE SAME Thrust-reverser assemblies (60) that utilize active flow-control and systems and methods including the same are disclosed herein. The thrust-reverser assemblies (60) define a forward thrust configuration (62) and a reverse-thrust configuration (64). The thrust-reverser assemblies (60) include a bullnose fairing (100) that defines a portion of a reverser duct (66) and an active flow-control device (150). The active flow-control device (150) is located to energize a boundary layer fluid flow within a boundary layer that is adjacent to the bullnose fairing (100) to resist separation of the boundary layer from the bullnose fairing (100) when the thrust-reverser assembly (60) is in the reverse-thrust configuration (64). The methods include flowing a thrust reverser fluid stream through the reverser duct (66) to generate the boundary layer and energizing a boundary layer fluid flow within the boundary layer with an active flow-control device (150) to resist separation of the boundary layer from the bullnose fairing (100). / / /FFig.2
