Abstract
【解決手段】上記目的を達成するために、本発明では、環状流路を構成するケーシング内面に取り付けられた複数の静翼列と、前記環状流路を構成する回転するロータに取り付けられた複数の動翼列とを有する軸流圧縮機において、前記静翼列または動翼列の周方向に隣接する翼の圧力面と負圧面とで区画される流路を、流路幅が最小となるスロート部を軸方向コード長50%より上流側に設け、かつ、該流路を区画する翼の翼前縁から翼後縁に沿った軸方向流路幅分布が、前記スロート部より下流側に変曲点を有するように構成する。
【選択図】 図1
Description
発明翼の流入角に対する全圧損失係数82を実線で表わし、点線で表わす従来翼の流入角に対する全圧損失係数81と対比している。図中に、一点鎖線で設計流入角83を示す。発明翼では設計流入角において、コーナーストールを抑制しているため、従来翼に比べて全圧損失を低減することが確認できる。また、流入角が大きい失速側でも、発明翼の全圧損失係数は従来翼と比較して、損失の増加が抑制されているため、広い作動範囲を有し、高性能化が図れることが分かる。
