Patent ID: 8484976

Claim:
A system for abating noise during emission of high pressure fluid, comprising: a device that emits a fluid flow at a high pressure through an aperture having an inner surface and an outer surface, the device comprising one of the following: an aircraft turbine engine, a turbine of a turbo generator, a microturbine, and seagoing vessel turbine power plant; a source of actuation air; an inner fluidic effector mounted to the device adjacent the aperture at the inner surface, the inner fluidic effector coupled to the source of actuation air for emitting an inner actuation air flow through the inner fluidic effector in a first direction; an outer fluidic effector mounted to the device adjacent the aperture at the outer surface, the outer fluidic effector coupled to the source of actuation air for emitting an outer actuation air flow through the outer fluidic effector in a second direction that is different than the first direction; the inner and outer fluidic effectors are positioned to increase a shear magnitude between the fluid flow and the flow of actuation air, force vorticity and increase penetration of the fluid flow and actuation air flows into each other; and the inner and outer actuation air flows combine with the fluid flow to reduce a noise level generated by the device.
