Description
ケーシング本体16は、軸方向に向かって縮径される内周面を有しており、その内部を酸素富化された空気が流れる(矢印x方向)ものである。静翼18は、飛行機の翼と同様の断面形状を有し、複数の静翼18がケーシング本体16の内周面上に全周にわたって配置されており、各静翼18は一定間隔でケーシング本体16の中心軸に向かって固定されている。このような周方向に沿って固定された複数の静翼18がケーシング本体16の軸方向に複数段配列されている。
なお、ケーシング本体16と静翼18の素材は、空気抵抗による応力に耐え得る強度を有し、耐熱性を有するものであれば特に限定されず、例えばケーシング本体16には炭素鋼が用いられ、静翼18にはステンレス鋼が用いられる。
回転軸部材20は、低合金鋼で製作された低合金鋼製部材であり、軸方向に向かって拡径する円柱状の形状を有し、ケーシング12内においてケーシング本体16の中心軸上に延在し、図示しない駆動手段により自らの軸周りに回転する。
動翼22は、飛行機の翼と同様の断面形状を有し、複数の動翼22が回転軸部材20の外周面上に全周にわたって配置されており、各動翼22は一定間隔で放射状に固定されている。このような周方向に沿って固定された複数の動翼22が回転軸部材20の軸方向に複数段配列されている。複数の動翼22の回転軸部材20の軸方向への配列と複数の静翼18のケーシング本体16の軸方向への配列は、交互に何段も並べられており、酸素富化された空気を連続的に圧縮して下流方向へ流すように構成されている。
なお、複数の静翼18および複数の動翼22の形状および向きは、酸素富化された空気を下流方向へ流すことができれば特に限定されない。また、動翼22の素材は、空気抵抗による応力に耐え得る強度を有し、耐熱性を有するものであれば特に限定されず、例えばステンレス鋼が用いられる。
ここで、酸化・発火抑制層24は、非鉄金属およびセラミックスのうち少なくとも1つから成り、酸化および発火を抑制して耐熱性を有するものであれば特に限定されず、市販の皮膜材を用いることができる。なお、非鉄金属としては、例えばアルミニウム、タングステン、鉛、亜鉛、金、銀、銅、ニッケル、コバルトなどが利用できる。また、セラミックスとしては、例えばシリカ、アルミナ、ジルコニア、炭化ケイ素などが利用できる。
この状態で、図示しない空気分離装置より導かれた酸素により酸素を富化された空気が、ケーシング本体16の空気吸入口26から吸入され、回転軸部材20に固定された動翼22の揚力による圧縮とケーシング本体16に固定された静翼18による整流(後方の動翼22の流入角度方向に転向)とを繰り返しながら連続的に圧縮されて下流方向へと流れていく。
