Test program was concerned with simulation of gas-particle rocket plume and creation of separated flow region around vehicle by plume up to nozzle exit to ambient pressure ratios Pj/Pinfinity of 10,000; B.H.Goethert's parameters for cold-flow testing are generalized to allow for presence of solid particles in flow and large pressure ratios; technique was developed for using commercial powders for simulation of solid particles in exhausts; gas-particle flows were violently erosive to Armco stainless steel; therefore, high-velocity areas within model plumbing were fabricated from erosion-resistant Elkonite and Stellite; results obtained.
