AERODYNAMIC STABILITY AND SYSTEM IMPACT ANALYIS OF SPACELINER PASSENGER AND RESCUE CABIN

Kurzfassung

The increasing interest in hypersonic passenger transport necessitates robust safety measures, particularly concerning emergency escape systems. This study focuses on the aerodynamic stability and system impact of the DLR SpaceLiner passenger and rescue cabin (SLC), aiming to ensure safe emergency separation across all flight phases and on the launch pad. A multi-objective evolutionary optimization algorithm is employed to explore five distinct design configurations that shall stabilize the spacecraft: fixed wing with flaps, fixed wing with flaps and canards, and three rotating wings in different orientations. These designs are optimized to balance three key objectives – maximizing the size of the stable flight corridor, minimizing the wing area, and reducing the added mass. Results highlight promising configurations that provide a favorable trade-off between stability, mass, and system impact. This study provides an important foundation for a detailed analysis of selected designs, contributing to the development of a safe and reliable emergency escape system.
