Technology readiness assessment of advanced space engine integrated controls and health monitoringAn evaluation is given for an integrated control and health-monitoring (ICHM) system that is designed to be used with hydrogen-oxygen rocket engines. The minimum required ICHM functions, system elements, technology readiness, and system cost are assessed for a system which permits the operation of H-O engines that are space-based, reusable, and descent-throttleable. Only the advanced sensors and some engine-dependent software are not found to be ready for applications to laboratory demonstration. Other systems related to the minimum functions are more developed, bringing the total system readiness to the conceptual design stage. Based on the evaluation of the H-O ICHM, it is estimated that the minimum system requirements for demonstration on an engine system testbed will require an investment of 30-45 million dollars over 6 years.
