Development and Demonstration of a N2O4/N2H4 Injector

Abstract

A program was conducted to develop and demonstrate a single-element coaxial injector with N2O4. The optimum injector configuration and one variant were employed in multiple-start, long-duration ablative chamber tests. The durability of the final injector configuration was demonstrated by over 460 seconds of operation in 44 starts, including hot restarts. Three basic configurations of the coaxial injector concept, with geometric variations, were tested to evaluate parameters controlling performance and injector/chamber compatibility, together with demonstrating the inherent dynamic stability of the injector.
