Abstract
Thrust-reverser assemblies that utilize active flow-control and systems and methods including the same are disclosed herein. The thrust-reverser assemblies define a forward-thrust configuration and a reverse-thrust configuration. The thrust-reverser assemblies include a bullnose fairing that defines a portion of a reverser duct and an active flow-control device. The active flow-control device is located to energize a boundary layer fluid flow within a boundary layer that is adjacent to the bullnose fairing to resist separation of the boundary layer from the bullnose fairing when the thrust-reverser assembly is in the reverse-thrust configuration. The methods include flowing a thrust-reverser fluid stream through the reverser duct to generate the boundary layer and energizing a boundary layer fluid flow within the boundary layer with an active flow-control device to resist separation of the boundary layer from the bullnose fairing.
