摘要： A rotor blade assembly (100) for a gas turbine engine (10) comprises two aerofoil members (120) joined together at their roots (122) by a blade assembly attachment web (130). The rotor blade assembly is made from a composite material, for example an organic fibre composite material. The blade assembly attachment web (130) is used to attach a plurality of rotor blade assemblies (100) to the rest of the gas turbine engine in order to form a rotor stage (12). The rotor stage (12) may, for example, be the fan stage of a turbofan gas turbine engine.

摘要： A steam turbine nozzle singlet (40) having a blade or airfoil (42) between inner and outer sidewalls (44, 46) is provided. The sidewalls include steps or flanges (56, 58) which are received in complementary recesses in the rings enabling axially short low heat input welds e.g., e-beam welds. These complementary steps and recesses mechanically interlock the singlet between the rings preventing displacement of the singlet in the event of weld failure. The low heat input welds minimize or eliminate distortion of the nozzle flow path. Additional features on the singlets, provide a datum for milling machines to form singlets of different sizes.
