Supersonic Annular Nozzles

Authors: D. MIGDAL;

Supersonic Annular Nozzles

Abstract

An analytical method is presented for the design of axisymmetric annular nozzles to yield uniform and axial flow. Computed results are used to display typical matched inner and outer contours, the effects of major initial flow variables, and the resulting wall forces. For axial inflow, the inner contour is longer than the matched outer contour, and there is an apparent maximum expansion area ratio. Variations in the initial flow angle can be used to vary the base height required from matching considerations, to effect the relative division of thrust and length between inner and outer contour. Previous plug-type nozzles are simple limiting cases of the annular nozzles described here.
