Abstract:

The aerodynamic performance of lifting reentry vehicles in the high Mach number Ma 10 and high altitude H 50 km regime is analyzed. Due to the high flight velocity chemical reactions and due to the low density viscous and rarefaction effects are of importance. Free flight data of the US-Shuttle and low density wind tunnel data of DFVLR are used. It is found that aerodynamic performance loss and a destabilizing pitching moment change can be explained by viscous-rarefaction effects.
