A fluidic effector provides enhanced plume mixing for an aircraft engine. Air jet injectors are located on both the external and internal cowl surfaces and angled in opposite directions to induce large scale vortices in the exhaust plume. The vortices mix actuation air with the exhaust plume to produce ejector action. The plume mixes out quickly, thereby lowering jet noise and jet exhaust temperature. The injectors have orientations and injection rates that are adjustable to allow variable mixing rates for use at different flight and engine conditions.
1. 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 ...
