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 se...
[ What is claimed is:] [23.] A method for vectoring a primary flow through a small area expansion ratio nozzle, comprising the steps of:directing the primary flow through a physical throat of the nozzle wherein the nozzle comprises:an opening for accepting a primary flow through the nozzle;a smooth convergent portion of the nozzle wherein said primary flow is subsonic;a physical throat coupling said converging portion to a diverging portion of the nozzle downstream of said physical throat;at least one primary injector located proximate to said physical t...
