A composite blade assembly (10) for mounting on a turbine wheel includes a ceramic airfoil (12) and an airfoil platform (14). The ceramic airfoil (12) is formed with an airfoil portion (16), a blade shank portion (18) and a blade dovetail tang (20). The metal platform (14) includes a platform shank (22) and a radially inner platform dovetail. The ceramic airfoil (12) is captured within the metal platform (14), such that in use, the ceramic airfoil is held within the turbine wheel independent of the metal platform. A turbine rotor wheel and a corresponding method of assembling a composite blade are also provided. |
