An investigation of the constant area, supersonic-supersonic ejector has been conducted wherein one supersonic stream is pumped directly by another inside a confining duct. The theoretical analysis is based on simplified, one-dimensional models of the constant area mixing section and inviscid interaction region. The parametric dependence of the ejector pressure recovery performance on each of seven dimensionless variables is presented. A series of small-scale, axisymmetric ejector experiments indicates that the theory predicts maximum ejector compression ratios that are 15-22% higher than the measured values and that the ejector is susceptible to separation of the secondary stream at the point of confluence of the primary and secondary streams.
