PARAMETERS CONTROLLING THE PERFORMANCE OF SECONDARY INJECTION
Abstract
Experimental data indicate that wide variations in the performance of secondary injection can be attributed to injectant-fluid properties and variations in the geometry of injection. A onedimensional model of this fluid-interaction process was analyzed to determine the effects of the injectant-fluid properties and motor variables on the pressure recovery of the main-stream gases. The motor parameters investigated were chamber pressure and propellant-flame temperature. The injectant parameters investigated were temperature, velocity, axial location of the injection port, angle of injection, heat of vaporization, specific heat at constant pressure, specific-heat ratio, and molecular weight. This analysis provides a better understanding of secondary-injection phenomena and establishes general criteria for the proper selection of injectants. (Author)
