Advanced Altitude Simulation P8: Current Status of Development

Abstract

The paper reports the current status of a DLR Lampoldshausen project towards the design, erection, and operation of an advanced altitude simulation facility at the European R&T Facility P8. The system will allow for testing of subscale thrust chamber assemblies (TCAs) including surrounding supersonic flow around the nozzle. This facility will allow for investigation into the speci¦c features of altitude simulation facilities but also on the interaction of nozzle and its exhaust plume and the surrounding flow for subsonic, transitional, and low supersonic coflow conditions. The design bases entirely on the broad experience on design and operation of various altitude simulation facilities such as the satellite engine bench P1.0, the cryogenic and storable upper-stage engine facilities P4.1 and P4.2, sophisticated engineering design tools and continuous numerical effort. Knowledge about nozzle and thrust chamber design and operation bases on broad investigations carried out at the cold-flow facility P6.2 and the hot-fire bench M3 and P8.
