ABSTRACT:
A method and apparatus for varying the effective area of a jet engine exhaust nozzle. The apparatus includes a center body disposed upstream of the nozzle throat and configured to form a recirculation wake extending to and through the nozzle throat. The conditions of fluid flow are selectively variable, for example, by axial movement of a portion of the center body, to vary that portion of the nozzle throat which is effectively blocked by the recirculation wake so as to be unavailable for downstream motive fluid flow.
