4010 Study on Low-ballistic-coefficient Atmospheric-entry Technology using Flexible Aeroshell

Abstract

A Low-ballistic-coefficient atmospheric-entry technology using a flexible aeroshell is promising for a space transportation system in next generation because it can reduce the maximum aerodynamic heating during a re-entry and the terminal velocity dramatically. Its technology will lead to realize a safer, cheaper and more universal space transportation system. Our group has researched various important subjects in order to apply the flexible aeroshell to actual atmospheric-entry missions. In this paper, the innovative re-entry system from LEO which was defined as the nominal mission by our group is introduced and our current research and development are reported.
