Embodiment Construction
[0024] FIG. 1 shows a turbine blade root 4 as well as a platform 2 and a partial airfoil 1 in radial section. The blade root 4 is inserted into a mortise 30 of the turbine wheel disk 3 and fixed in a form-closed manner by means of the mortise teeth 35 of the blade root 4 and the corresponding teeth 36 on the mortise 30 , as shown in FIG. 2 . The blade root 4, the platform 2 and the airfoil 1 are integrally formed, preferably poured into one body. The side-by-side airfoils 1 provide resistance to the flowing hot gas and change its speed and direction, thereby causing the turbine wheel disk 3 to rotate at a high rotational speed around the disk axis. The centrifugal forces that occur in this case essentially have to be absorbed by the teeth 35 of the blade root 4 and the teeth 36 of the groove 30 . Especially in the case of turbine blades without internal cooling, a large part of the turbine blade is usually solid and thus has a high weight, which places a considerable load on ...
