JAXA Research and Development Report: Research Reports on High Altitude Balloons
Membrane aeroshell has a potential for application to re-entry capsules and planetary-entry probes in the future due to its low mass and low storage volume. Its characteristics, however, is not well understood particularly in high speed flow regions. The flight test using the scientific balloon is conducted to demonstrate its high speed flight capability on September 1st, 2003. This paper describes the outline of this project, the development report of the flight model with the flare-type membrane aeroshell, and the results of the flight tests. Despite the flight model dropped with a gondola because of the trouble in the separation device, there are a lot of accomplishments in this project; 1) to obtain the knowledge about the deformation, stability, and aerodynamic characteristics of the flare-type membrane aeroshell by pre-flight wind tunnel test, 2) to demonstrate that 1.35 meter diameter membrane aeroshell can be stowed in a backside of the 0.5 meter capsule and deployed automatically in the ground test, and 3) to verify that the almost all of the sensors installed in the capsule worked normally at the high altitude and the deployed membrane aeroshell can withstand the actual flight environment.
