At low temperatures, the proportion of conductive heat transfer through MLI blankets is large compared to that of radiative heat transfer, hence the decline in thermal insulation performance is significant. A new type of MLI blanket using new spacers ; the Non-Interlayer-Contact Spacer MLI (NICS MLI) has been developed. This new MLI blanket uses small discrete spacers and can exclude uncertain interlayer contact between films. The insulation performance is measured with a boil-off calorimeter. Because the NICS MLI blanket can exclude uncertain interlayer contact, the test results showed good agreement with estimations. Furthermore, the NICS MLI blanket shows significantly good insulation performance (effective emissivity is 0.0015 at ordinary temperature), particularly at low temperatures, due to the high thermal resistance of this spacer.", 資料番号: AC1500069000, レポート番号: JSASS-2014-4422}, publisher = {日本航空宇宙学会(JSASS), The Japan Society for Aeronautical and Space Sciences (JSASS)}, title = {ボイルオフカロリメータ法による層間非接触型スペーサMLIの断熱性能評価}, year = {2014} }
