Abstract
An exemplary engine noise reduction system, can be provided, which can include a noise reduction fluid source, and a microjet(s) placed at an axial location downstream from a nozzle exit of an engine and configured to asymmetrically inject a noise reduction fluid from the noise reduction fluid source into a jet flow of the engine. The engine can be a jet engine. The microjet(s) can include four microjets, which can be about 90 degrees apart in a plane at the axial location. The four microjets can be asymmetric microjets. The microjet(s) can be configured to inject the noise reduction fluid in a direction that is normal with respect to the jet flow.
