Honeycomb structure: how it works<\/h2><\/span>
<\/div><\/div><\/div>

A honeycomb structure<\/strong> consists of a metallic cellular matrix<\/strong>, similar to a honeycom<\/strong>b, manufactured from thin foils assembled and spot welded together. This configuration creates a highly porous and controlled surface, designed to interact with the rotating parts of the machine.<\/p>\n

Unlike solid surfaces, the cellular geometry helps dissipate energy and reduce turbulence phenomena, creating a \u201ctortuous\u201d path for the fluid that limits unwanted leakage.<\/p>\n<\/div>

Abradable function: protection and precision<\/p>\n

<\/h2><\/span>

<\/div><\/div><\/div>

One of the most important features of honeycomb seals is their abradable nature<\/strong>. In the event of contact with the rotor blades, the structure wears in a controlled manner without damaging the most critical components.<\/p>\n

This behavior allows for:<\/p>\n
