- Abstract
The intent of this paper is to provide an overview of the VULCAIN X technological demonstration roadmap progress at the end of 2007. The VULCAIN X engine is a LOX/LH2 modular and evolutive ground demonstrator engine for new propulsion technologies, based on a VULCAIN 2 engine, and defined to perform both systems and sub-systems technological demonstration on test-bench, whose principal targets is cost reduction, robustness, reusability and VULCAIN 2 engine evolutions. The different Demos X that are under studies and for which one hardware will be manufactured by the end of 2007 are the Hydrogen turbo-pump TPX, the gas generator GGPX and its injection high bandwidth regulation valves VRR, the electrical hot gas valve VGC and the sandwich nozzle extension NEX. At system level, the main subjects that are being explored are the simplification of the chill-down procedure, immediate tests diagnosis (health monitoring system), mechanical integration evolutions and smooth transients. The logic for the first steps of this program are : • System demonstration, combined with characterization of limited modification at sub-systems or system level on VULCAIN 2 hardware dedicated to production follow-up tests campaign ARTA between 2005 and 2008 • Sub-systems demonstration on a power-pack system GPX to characterize and validate the limitations of the different sub-systems in 2008 • Full demonstration at engine level in 2009/2010 The VULCAIN X program is managed by the Centre National d’Etudes Spatiales (CNES). The publication will focus on the major achievements during the 2007 period, i.e. the presentation of the passengers test logic foreseen on ARTA 8, the main needs for sub-systems and system demonstration at engine level and power-pack level and the main achievements of the manufacturing of the different Demos X. The kick-off of the program took place at the end of September 2005. The first system passenger tests took place on the production follow-up ARTA 7 campaign during the summer of 2006. All the different demos X of the project VULCAIN X have successfully passed their Preliminary Definition Review and are entering the detailed definition phase.
