| description | PROBLEM TO BE SOLVED: To provide the positioning of airfoils to reduce pressure variations entering a diffuser.SOLUTION: One embodiment includes a turbomachine comprising a diffuser and a plurality of airfoil rows, including (1) a first airfoil row adjacent to the diffuser and being of a first type selected from the group consisting of stationary vanes and rotating blades, (2) a second airfoil row adjacent to the first airfoil row and being of a second type different from the first type, and (3) a third airfoil row adjacent to the second airfoil row and being of the first type. At least one of the plurality of airfoil rows is clocked relative to another airfoil row of the turbomachine, reducing variations in airflow circumferential pressure at at least one spanwise location in the diffuser adjacent to the first airfoil row in an operative state of the turbomachine.
【課題】ディフューザに入る圧力変動を低減するためのエアフォイルの位置決め。【解決手段】一実施形態は、ディフューザと、（１）前記ディフューザに隣接していて、静翼及び動翼より成る群から選択された第１の種類より成る第１のエアフォイル列、（２）前記第１のエアフォイル列に隣接していて、前記第１の種類とは異なる第２の種類より成る第２のエアフォイル列、及び（３）前記第２のエアフォイル列に隣接していて、前記第１の種類より成る第３のエアフォイル列を含んでいる複数のエアフォイル列とを有するターボ機械を含み、前記複数のエアフォイル列の内の少なくとも１つのエアフォイル列が、前記ターボ機械の別のエアフォイル列に対してクロックされて、ターボ機械の運転状態中に前記第１のエアフォイル列に隣接した前記ディフューザ内の少なくとも１つのスパン方向位置における空気流の円周方向圧力の変動を低減する。【選択図】図１ |
