7.2.3 Remedies for Labyrinth Rubbing Damage
<a id="labyrinth-damage-remedies"></a>
The design and construction of labyrinth systems must take the following operating loads into account:
Temperature gradient-induced stress (static, LCF):
Thermal strain can occur during steady and unsteady operation. It is caused by the heat ratios in engine parts, which are influenced by leakage air flow and heat created by friction during rubbing. Temperature gradients that change over time cause cyclic…
