Platformless turbine blade

摘要

A turbine blade rotor assembly is disclosed for a gas turbine engine. The assembly includes a rotor (12) having nickel alloy turbine blades (14) secured thereto. Each of the blades (14) includes a root (18) and an airfoil (20). The roots (18) are supported by the rotor (12). A ceramic matrix composite platform (34) separate from the turbine blades (14) is supported between each pair of the turbine blades (14) adjacent to the airfoils (20).
