A description of the test apparatus and some major experimental results are presented. The test apparatus is a pressurized test cell for simulation of translational motion by pressurization of the inlet flow to the corresponding stagnation pressure. The experiment consisted of measurement of the pressure distribution along the ejector surfaces and of the pressure, temperature and forces required to evaluate the mass flow, total forces and the ram drag. In addition, Schlieren photographs were taken at each test to observe the flow and in particular to illustrate the shock wave patterns. Combination of the pressure distribution and Schlieren photographs illustrate the successful achievement of second solution flows. Further tests are to be performed to illustrate the optimization of second solution performance and for comparison between theory and experiment. Author
