Abstract
Description
多層断熱材は、放射率の低い断熱シートを重ねて形成される。このような多層断熱材では、断熱シートの層間にスペーサを介挿することで、断熱シート相互の接触による熱伝導を防ぎ、断熱効果を高めている。
このような多層断熱材で宇宙機又は宇宙機搭載機器を覆うことで、宇宙機外部からの輻射による入熱を抑制すると共に、宇宙機内部からの輻射による放熱を抑制する。これにより宇宙機の温度環境を適正な作動温度域に維持することができる。
下記の特許文献1では、サーマルブランケットを、面ファスナ(ベルクロ(登録商標)テープ)を用いて取付面へ装着する方法が開示されている。
即ち、本発明の多層断熱材は、断熱シートとスペーサとが積層された断熱部材と、前記断熱部材に隣接して設けられた係止用シートと、前記断熱部材と前記係止用シートとを貫通して係止する断熱部材係止具と、前記係止用シートに設けられ、装着対象物に対して着脱可能とされた装着部材とを備え、前記断熱部材係止具は、前記断熱部材の各層が密着しないように係止することを特徴とする。
以下、本発明の第1実施形態に係る多層断熱材について、図面を用いて説明する。
以下、本発明の第2実施形態に係る多層断熱材について、図面を用いて説明する。
まず、装着対象物9を囲う所定の立体形状13’を想定し、この立体形状13’を展開した展開図を作成する。この展開図を構成する個々の面の形状に基づき、それぞれの係止用シート片13aを図11に示したような形状に形成する。それぞれの係止用シート片13aの厚さや材質は、装着対象物9の形状に沿わせて多層断熱材11を変形させる際に、係止用シート片13aが形状を維持し、かつ、壊れずに断熱部材係止具5の係止部を係止できるよう選択する。それぞれの係止用シート片13aの周縁部を、展開図を形成するようにシート接続部13bで接続して(図7参照)、係止用シート13を形成する。例えば粘着テープあるいは樹脂フィルムをシート接続部13bとして使用する場合は、係止用シート13を折り曲げる際に内側になる側から、係止用シート片13aの周縁部へ接着させる。係止用シート13には、装着部材4を縫い合わせるなどして締結する。好適な例としては、装着部材4は、係止用シート13を折り曲げる際の中心に位置する係止用シート片13aに締結される。また、多層断熱材の装着のため複数の係止用シート片13aに複数の装着部材4を装着するようにしてもよい。(ステップ2−1)
