摘要

Static tests are conducted to establish reference performance levels for a round convergent nozzle and a 3.3area ratio, 37-tube suppressor nozzle. After assessing bare nozzle performance characteristics,ejector shrouds are added,and the effect of secondary inlet changes and ejector length change on thrust is established. Pressure measurements on nozzle/ejector surfaces are correlated with measured thrust. The secondary flow is measured,and the flow conditions inside the ejectors are established by performing pressure/temperature traverses. (Author)
