摘要： A turbine blade assembly, in particular of a gas turbine, is provided. The turbine blade assembly includes a turbine disc with rotor blades inserted into notches of the turbine disc and locking plates that are placed inside circular grooves with rims in the turbine disc and in the rotor blade. The edges of the locking plates that are oriented towards the center of the turbine disc are castellated by providing teeth and accordingly a part of the rim of the circular groove of the turbine disc is also castellated by providing gaps and whereby the gaps of the rim match the teeth of the locking plates. The locking plates have a spring-back force to provide both locking and sealing capabilities during engine operation.

摘要： A blade root including of a plurality of lobes and fillets and flanks in between is provided. A shoulder is provided between the flanks and the fillets to increase the distance to a corresponding lobe of a corresponding rotor disc into which a blade with such a blade root is inserted. A rotor blade having such a blade root is also provided. Furthermore this feature may alternatively or additionally also be applied to a rotor disc slot of a rotor disc, such that a flank of the rotor disc slot merges into a fillet of the rotor disc slot via a soft shoulder to increase the distance to a corresponding lobe of a blade root. A shoulder could also be applied to both the blade root and the corresponding slot of the rotor disc.

摘要： A root section of a rotor blade for interacting with working fluid upon rotating the rotor blade is provided. The root section includes a curved cooling passage for guiding a cooling fluid within the root section. A cooling fluid entry plenum has an entry aperture for introducing the cooling fluid into the cooling passage. A platform is located at a radially outer end of the root section. The curved cooling passage penetrates through the platform, and the following condition is satisfied at least in a portion of a radial extent of the cooling passage: 0.25*dr
