A tandem blade lattice having characteristics enhanced is provided. In a high pressure ratio blade lattice, inevitable generation of an shock wave is shifted, as much as possible, toward a rear portion of an upper surface of a front blade to inhibit separation from a blade surface from being caused by interference of theshock wave and a boundary layer, and boundary layer control is performed such that a speed, a momentum and the like of a jet flowing from a trailing edge of alower surface of the front blade onto an upper surface of a rear blade are regulated to obtain a flow along the upper surface of the rear blade, so that separation of the boundary layer on the upper surface of the rear blade is restricted to a vicinity of a trailing edge.

La présente invention fait état d'un treillis d'aubes améliorées montées en tandem. Dans un treillis d'aubes travaillant à pression élevée, l'inévitable onde de choc qui est générée est dirigée, le plus possible, vers l'arrière de l'extrados d'une aube avant pour éviter qu'il y ait décollement d'une surface d'aube due à l'interférence entre l'onde de choc et une couche limite. Les couches limites sont surveillées afin que la vitesse, la quantité de mouvement et autres caractéristiques semblables d'un flux d'air allant du bord de fuite de l'intrados d'une aube avant vers l'extrados d'une aube arrière forment un écoulement le long de l'extrados de l'aube arrière afin que le décollement de la couche limite de l'extrados de l'aube arrière soit contenu aux environs du bord de fuite.
