Abstract:
1. A blade for mounting with other blades in a circumferential direction around a disk, the blade comprising: an airfoil having a pressure side and a suction side; a pair of midspan shrouds located on the airfoil, each shroud having a planar contact face, the contact faces facing in opposite circumferential directions of the blade, wherein one midspan shroud extends in the circumferential direction from the pressure side and the other midspan shroud extends in the circumferential direction from the suction side; at least one recess on each of the contact faces of the midspan shrouds so that each recess is surrounded by one of the contact faces of a corresponding one of the midspan shrouds; and a wear pad disposed within each recess of the midspan shrouds, each wear pad having a contact surface that is surrounded by the contact face of the corresponding midspan shroud so that a portion of the corresponding contact face shields the wear pad from pull loads and rub loads during a shingling/rebound event with a midspan shroud of a second blade mounted circumferentially adjacent to the blade on a disk.
