Abstract
【解決手段】 軸流型圧縮機の翼列を構成する翼が、背面SSの前縁部分に形成された曲率が負の凹部17と、凹部17の後方に連続する曲率が略ゼロの平坦部18とを備えることにより、圧縮波を複数に分散させ、第1通路衝撃波の強さを緩和でき、圧力損失の低減および背面の境界層の剥離を抑制することができる。それに加えて、翼の腹面PSの前半部分に曲率が負の凹部14を備えることにより、腹面PSの前半部分における空気流の流速の増加を抑制し、腹面PSに発生する第2通路衝撃波を弱めることで圧力損失を低減することができる。前記凹部14は、コード長の10%以下の位置から20%以上の位置に跨がって存在すれば更に有効である。
