Abstract: A device including a resonant array of a plurality of synthetic jet generators where neighboring jet generators are coupled, resulting in the potential for constructive and destructive interference between jets of the plurality of synthetic jet generators depending on the relative phase of a corresponding plurality of drive signals to plurality of synthetic jet generators. The device also includes a controller configured to control the relative phase of the corresponding plurality of drive signals to effect a change in a first jet emitted by a first synthetic jet generator of the plurality of synthetic jets by changing a given phase of a second jet emitted by a second synthetic jet generator of the plurality of synthetic jet generators.

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.
