Abstract

A rotor assembly has a sealing system for sealing at apexes or faces of the rotor. An apex seal or face seal comprises a compliant member that is configured such that the shape or orientation of the compliant member can change in use in response to a change in the speed of rotation of the rotor, a change in the pressurization across the compliant member, or a change in clearance between the sealing surface and a mounting element to which the compliant member is mounted, to deflect towards or away from the sealing surface.
