A turbine wheel (100) for a gas turbine engine, the turbine wheel (100) comprising a disk (102) formed to include a dovetail slot (110) that extends through the disk (102) in an axial direction from a forward side (104) to an aft side (106) of the disk (102) and inwardly in a radial direction from an outer diameter of the disk (102) toward a central axis,
a blade (10) comprising ceramic-containing materials, the blade (10) formed to include an airfoil (16) that extends outwardly in the radial direction from the outer diameter of the disk (102) and a root (12) that extends into the dovetail slot (110), the root (12) including a stem (20) that extends from the airfoil (16) into the dovetail slot (110) and a pair of pin receivers (22) arranged in the dovetail slot (110) that extend circumferentially from the stem (20) in opposing directions, and a pair of retention pins (30) each arranged in the pin receivers (22), the pair of retention pins (30) are arranged on circumferentially opposed sides of the stem (20) and are arranged radially between the pin receivers (22) and the disc (102) so that centrifugal forces applied to the blade (10) when the turbine wheel (100) is rotated about the central axis are transferred through the pair of retention pins (30) to the disk (102). |
