Definitions
- the shape of the Disjustiervoriques 20 can be largely arbitrary and generally depends on the available space. Decisive in the form is the height, as in Fig. 4 is shown. In the example shown there, the height of the self-aligning device 20 under the condition of machine standstill corresponds to the minimum difference g t, min (the transient gap contribution) that would be present without the use of the self-aligning device 20.
- the centrifugal forces acting on the blade are transmitted via the finger 18 through the self-aligning device 20 to the groove 17 in the rotor 12. These forces increase with increasing rotational speed.
- the elastic properties of the self-aligning device 20 at the height g t prevent the device from being pushed flat. As a result, the game at the blade tip remains the same Bucket length greater than without the Disjustiervorides 20. However, a certain flattening of the Disjustiervorides 20 due to the mechanical stress can be accepted.
- NiTi-based shape memory alloys could be considered in the area of the hot blade root whose allowable working temperature reaches up to 200 ° C when cooling with secondary air is available in a gas turbine.
- Ternary high-temperature NiTiX alloys and others containing Hafnium Hf, Palladium Pd and / or Platinum Pt as element X extend the working temperature range up to 800 ° C and more.
- other materials / alloys may be used, provided they have the desired and required properties.
