- Abstract
The Japanese Experiment Module (JEM) is the manned pressurized modules used as research laboratories on orbit and planned to be attached to the International Space Station (ISS). The HII Transfer Vehicle (HTV) is the carrier to transfer cargos including daily commodities, research materials and equipments required for regular replacement to the ISS. Protection system from Micrometeoroids and Orbital Debris is important for crew safety aboard the ISS. We have to design a manned module with shields attached to the outside of the pressurized wall so that JEM and HTV can be protected when debris impact on the wall. The Hypervelocity Impact Testing (HVIT) for the JEM was conducted to verify the shield performance during the JEM development using Two Stage Light Gas Gun (TSLGG) and the development phase of the JEM shield was finished successfully. The shield design for HTV is based on the knowledge obtained in the JEM development, however the shield configuration is different between the JEM and HTV, for example, Solar Array Panels, thickness of Front Bumper and Pressurized Wall etc. In 2004, the HVIT for the HTV was also conducted to assess the unique shield performance using TSLGG. In this paper, we identify the differences of JEM/HTV shields and focus on the assessment of the shield performance, comparing the HVIT results of JEM and CAM, especially on the effect of the difference of the shield design on the shield performance.
