STV engine requirementsThe Space Exploration Initiative program and the Space Transfer Vehicle studies provide the opportunity to evaluate the engine requirements for the next generation space engine within the context of a credible but technologically demanding program. Some of these requirements are generic, basically independent of the architecture, and others are mission and configuration dependent. Generic requirements include high reliability, space-basing, man-rataing, long life and reusability, and extended health monitoring, including automatic pre-mission checkout. Mission and configuration dependent requirements include vehicle/engine interfaces, engine throttling, performance specifications, engine system architecture, and operational requirements. It is argued that engine technology requirements must be extended from the usual performance-related issues to encompass reliability, space-basing, life, and extended health monitoring.
