Abstract: An apparatus and method for varying the effective cross sectional area of an opening through a nozzle provides a controller 78 that pulses a fluidic cross flow through an injector associated with the nozzle 68 proximate to the opening of the nozzle. The controller 78 directs the injector 76 to provide a pulsed cross flow having a predetermined frequency, amplitude, or wave form. The pulsed cross flow interacts with a primary flow 14 through the nozzle 68 to partially block the nozzle's opening 72, thereby effectively decreasing the cross sectional area of opening 72 in a jet engine 42. A plurality of pulsed cross flows proximate to a nozzle's throat 70 permits effective afterburner 64 operations even with a fixed geometry nozzle by allowing throttling of the primary flow 14. Further, variations in the cross flow's orientation pulse frequency, amplitude or wave form, or the cross flow's mass flow characteristics can allow vectoring of the primary flow 14.

Abstract: An apparatus and method for varying the effective cross sectional area of an opening through a fixed geometry nozzle provides a fluidic cross flow with an injector incorporated in the throat of the nozzle 68 proximate to the subsonic portion of the flow through the nozzle. One or more injectors 76 are directed at an injector angle opposed to the subsonic portion of the flow. The opposed cross flow from injector 76 interacts with a primary flow 14 through the nozzle 68 to partially block the nozzle's opening 72, thereby effectively decreasing the cross sectional area of opening 72 in a jet engine 42. A plurality of cross flows proximate to a nozzle's throat 70 permits effective afterburner 64 operations even with a fixed geometry nozzle by allowing throttling of the primary flow 14. Further, variations in the cross flow's mass flow characteristics or injection angle can allow vectoring of the primary flow 14.
