1. A propulsion system, comprising:
an engine configured to discharge a pressurized flow; a nozzle system configured to receive the pressurized flow, wherein the nozzle system includes a nozzle, an inflected throat and at least two fluidic injection zones, wherein the inflected throat includes a first throat portion having a first throat flow area, and a second throat portion having a second throat flow area, wherein the first throat portion and the second throat portion face different directions, wherein the nozzle system is configured to discharge a first portion of the pressurized flow from the first throat portion in a first direction by reducing flow through the second throat portion using at least a second fluidic injection zone, and to discharge a second portion of the pressurized flow from the second throat portion in a second direction different from the first direction by reducing flow through the first throat portion using at least a first fluidic injection zone, further comprising a plurality of independently controllable fluidic injectors, including a first fluidic injector positioned in the first fluidic injection zone proximate to the first throat portion and a second fluidic injector positioned in the second fluidic injection zone proximate to the second throat portion, wherein the first fluidic injector is operable to reduce flow through the first throat portion; and the second fluidic injector is operable to reduce flow through the second throat portion, further comprising: a third fluidic injector in the first fluidic injection zone proximate to the first throat portion and positioned across the first throat portion opposite to the first fluidic injector; and a fourth fluidic injector in the second fluidic injection zone proximate to the second throat portion and positioned across the second throat portion opposite to the second fluidic injector, wherein the nozzle system is configured to: generate a yaw moment in a first yaw direction by increasing flow through the first throat portion by activating the second fluidic injector and the fourth fluidic injector to reduce flow through the second throat portion; and to generate a yaw moment in a second yaw direction by increasing flow through the second throat portion by activating the first fluidic injector and the third fluidic injector to reduce flow through the first throat portion; and generate a pitch moment in a first pitch direction by activating the first fluidic injector and the second fluidic injector; and to generate a pitch moment in a second pitch direction by activating the third fluidic injector and the fourth fluidic injector.
