Emergency escape vehicles and mechanisms for space shuttles

This study considers emergency escape vehicles (EEV) design for Space Shuttles. The proposed EEV has the reverse Apollo-style cone configuration, contains a manned gyro-stabilized suspension rotator sphere, and has a collapsible module. Therefore, it gives astronauts a high permissible gravitational loading and survivability. The proposed EEV has high volumetric efficiency and is removable, so the Space Shuttle still can carry a large payload. The designs of the EEV system greatly extend the lifespan of the remaining space shuttle fleet indeed.
