Towards a simplified model for the prediction of plain bearing wear in the Variable Stator Vane system

Résumé

The Variable Stator Vane (VSV) bushings wear in turbojet engine maintenance is a significant problem re- quiring adapted models. The VSV bushings are located in a complex system and are exposed to combined and time-varying loadings. This study aims to predict the wear evolution of the VSV bushings, taking into account the complexity of the geometry of the system and the loadings with adapted computational time. This paper presents a three-dimensional semi-analytical formulation of this highly nonlinear wear problem solved with the Newton-Raphson method.
