AbstractThe flexible aeroshell have been proposed as one of the new concept of the atmospheric-entry system. The vehicle with flexible aeroshell can reduce the aerodynamic heating due to the low-mass and large area because it can decelerate at a high attitude where the atmospheric density is very low. It leads to improve the relativity and safety of atmospheric-entry systems. As a first step for a practical use of this concept, the drop flight of the capsule with the membrane flexible aeroshell was planned and conducted using a large scientific balloon by the collaboration team of University of Tokyo, Kyushu University and ISAS/JAXA at 28th August in 2004. In this flight test, the flight model was separated at an altitude of 39 km and conducted a free flight. The flight data show that the flight model was stable in both transonic and subsonic flow regimes and its flight path and aerodynamic characteristics were good agreement with the results of the trajectory analysis and the wind tunnel tests. This fact indicates that the flare-type flexible aeroshell has good deceleration performance.
