Project Outline

Elastomeric rotor bearings are key components in modern helicopter rotor systems. Their structural performance and service life are strongly influenced by the fatigue behavior of the laminated elastomer-metal architecture. The objective of this project is to perform a structured literature review on fatigue in elastomeric rotor bearings and related elastomer-metal laminates. Experimental investigations, material systems, failure mechanisms, fatigue criteria, and modelling approaches will be reviewed and consolidated. The collected information will be used to identify open research questions and provide recommendations for  future rotor bearing fatigue investigations.
