Abstract
Experimental measurements of side force for an underexpanded two-dimensional nozzle and an axisymmetric contraction for a three-dimensional nozzle with side wall translation demonstrate that vectored angles of 20 deg can be obtained at a pressure ratio of 11.5. For a vectored control jet the magnitude of side force can be increased by the translation of the side wall where the optimum length is dependent on the pressure ratio value. The inviscid wave equation results are in good agreement with the experimental two-dimensional measurements. The optimum length of extension for the three-dimensional nozzle occurs at 1.6 times the throat dimension with similar thrust vectoring capability. The physics of the expansion and the jet momentum turning are qualitatively described using an optical schlieren system.
