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 bl ade 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 surfa ce of a rear blade are regulated to obtain a flow along the upper surface of the rear blade, so that separati on of the boundary layer on the upper surface of the rear blade is restricted to a vic inity of a trailing edge. |
