INVESTIGATION OF TWO-NOZZLE CLUSTER DIFFUSEREJECTOR WITH AND WITHOUT EJECTED MASS

Abstract

An investigation was conducted to determine the best shape for a diffuser-ejector configuration for a two-nozzle cluster rocket and included the performance of various combinations of configurations derived from six basic diffuser-ejector geometric shapes and sizes and four basic arrangements of nozzle configurations. The performance was obtained for all configurations both with and without ejected mass from the test cell. The ejected mass from the test cell was accomplished by two parallel auxiliary jet pumps. The simulated rocket nozzles were conical 13.25-deg half angle. Unheated dry air was used as the driving fluid for the simulated rocket and jet pumps. Saturated 200-psig steam was also used as a jet pump driving fluid.
