The SCRAMSPACE I scramjet flight experiment feasibility study

The Phase A activities of the development of the SCRAMSPACE I scramjet-powered freeflight experiment are described in this paper. The objectives of this flight are first described together with the definition of the primary, secondary and tertiary experiments. The Scramjet configuration studied is first discussed together with the rocket motor system selected for this flight. The different flight sequences are then explained, highlighting the SCRAMSPACE I free-flyer separation and re-orientation procedures. A trajectory analysis and the derived thermo-structural analysis are presented, discussing the alignment of the predicted performance with the mission scientific requirements. The global system architecture and instrumentation of the vehicle are then explained. The conclusions of these Phase A technical activities are that the presented mission concept is in line with the SCRAMSPACE I scientific requirements and no major technical difficulties have been identified.
