New bore aerodynamic bearing

A new bore design of a self-acting gas journal bearing has been conceived and developed for enhancing the load carrying capacity and dynamic stability parameters as compared to conventional bump-foil bearing. The new bore design involves the synergistic presence of bump foil and rigid bore segments. The new bore design yielded 5–260% increase in minimum film thickness and 80–175% improvement in stability parameters in comparison to conventional bump-foil journal bearing.
