THRUST VECTORING WITH A PLUG NOZZLE BY PLUG TRANSLATION

Abstract

A theoretical and experimental investigation was made of a convergent plug exhaust nozzle to determine if thrust vectoring could be achieved through the use of a translating plug which traveled in plane motion across a base region of slightly increased diameter. The objectives were to determine the angle which the resultant thrust vector made with the axial direction when the plug was translated and, to determine the loss in axial plug wall thrust due to the step. The method of characteristics was applied to determine the theoretical pressure distribution over the plug wall contour of a basic Mach 2 plug nozzle with the plug in the fully translated position. To verify the above results the experimental study was made using a two-dimensional nozzle tested in cold flow. Good qualitative correlation was obtained between the method of characteristics solution and experimental results.
