Monopropellant Hydrazine Engine Evaluation with Shell 405 and Shell X-4 Catalysts.
Abstract
Test and evaluation of five 75-lb thrust monopropellant hydrazine engines developed by Rocket Research Corporation were performed with both Shell 405 and Shell X-4 catalysts to determine the suitability of the hardware for meeting initial Post Boost Propulsion System (PBPS) design requirements. The original engines with Shell 405 catalyst failed to deliver the required minimum thrust level (71.25 lb/f when tested at the AFRPL. Two of the test engines were refurbished with Shell X-4 catalyst and exceeded all of the minimum specified design and operating requirements with a delivered vacuum thrust and specific impulse in excess of 75 lb/f and 220 seconds, respectively, for the complete design life of 500 seconds. A third refurbished test engine was subjected to two ambient restarts and failed to deliver the minimum required thrust and specific impulse after 280 seconds of operation. (Author)
