An experimental investigation was made of a convergent plug exhaust nozzle to determine if effective thrust vectoring could be achieved through the use of a translating plug which travels in plane motion across a base region of slightly increased diameter. The objective was to determine if effective thrust vectoring could be obtained at higher pressure ratios than 6.2. Results showed that when operating at pressure ratios below the design value the amount and direction of thrust vectoring obtained was a strong function of the pressure ratio. For underexpanded operation the thrust vectoring was found to be nearly independent of the pressure ratio, but of too small a magnitude to be significant. The axial thrust was materially reduced by the step in both plugs.
