Aerodynamic Design of a Reusable Booster Stage Flight Experiment

Kurzfassung

The DLR Project ReFEx is a flight experiment to gain experience for future HTVL reusable rocket stages. The focus of this paper lies on the aerodynamic properties and difficulties during the reentry flight. The stable flight envelope, regions with little and without aerodynamic stability and the analysis of various forms of stable and unstable motion are covered. The test flight is scheduled for 2022.
