Abstract

JAXA is developing the HTV small re-entry capsule (HSRC) with a diameter of 0.84 meters aiming for experimental sample returning from the International Space Station also for basic technology demonstration of a re-entry vehicle. The temperature requirements of payload (within 4±2deg.C for 3.5days) will be accomplished by a passive heat storage technique utilizing COTS-based staggered-folded vacuum double layer insulation. In addition, re-entry phase and descent phase using a parachute is also challenging due to heat dissipation of internal electronics as well as a harsh aero-heating environment. This paper describes the mission overview of HSRC including the results of thermal design and analysis to show that the mission is feasible but it needs further effort to ensure the sufficient temperature margin.
