Jet Engine Compressor Casing Runner Pads


The compressor casing in a jet engine is an extremely valuable part that requires protection against blade tip abrasion, while aiming for the tightest distance between the case and blade tip for optimal compressor performance. Casings are made of high performing metals to sustain the mechanical conditional constraints as well as the harsh environment, debris and pollutant that can damage various parts. This critical area needs to avoid pollutant release in the downstream part of the jet engine. 


Stator runner pads are wear parts with very tight tolerances and protect the compressor casing. They must consistently sustain high vibration, high temperature and high abrasion with excellent, micro-crack resistance in a challenging thermo-oxidating atmosphere. Furthermore, these parts must release very few particles on impact.

Precision parts that protect your compressor system


By using Hycomp™ H310® and H300 materials that have been co-molded, the compressor stator runner pads are able to combine high temperature and thermo-oxidative stability with excellent mechanical performance and impact resistance properties. These carbon fiber composites provide excellent wear resistance and friction control, improving the lifetime of the compressor part. As an aviation composite solution, the runner pads also significantly improve weight.
