Advanced Simulations of Reusable Hypersonic Rocket-Powered Stages

After successful completion of the MRR, technical progress of the SpaceLiner ultra-high-speed rocket-propelled passenger transport is achieved in Phase A conceptual design work. Following geometry refinement the structural design is maturing based on extensive trade-offs. Aerodynamics are investigated by numerical CFD-simulations of the two winged stages and will be supported by windtunnel tests. Aerodynamic control surfaces of the passenger cabin and rescue capsule and its subsystems are defined. Alternative options for the capsule with innovative morphing shapes are critically investigated taking into account system aspects, structural design, and advanced CFD-simulations. Potential intercontinental flight routes, considering range-safety and sonic boom constraints as well as good reachability from major business centers, are evaluated and flight guidance schemes are established. Extensions to this trajectory model are implemented to investigate the attitude dynamics and related controllability issues of the asymmetric launcher configuration. The space transportation role of the SpaceLiner concept as a TSTO-launcher is now addressed in technical detail.
