Abstract
the RETPRO (Validation of Wind Tunnel Test and CFD Techniques for Retro-propulsion) project, part of ESA´s Future Launchers Preparatory Programme (FLPP), aims to investigate launch system reusability technologies using wind tunnel testing and computational fluid dynamics (CFD). This paper describes and summarizes the CFD based aerothermal load predictions for a Vertical Take-off Vertical Landing (VTVL) reusable launcher configuration during the retropropulsion phase. An analysis of representative numerical results, obtained for the case Mach 5.3 and three active engines, is provided with the aim to show typical flow field phenomena and the resulting heating patterns occurring on the launcher surface. Parametric studies are performed to evaluate the effect of the number of operating engines, thrust vector control and different fuels (hydrocarbon vs. hydrogen).
