<p>A rotor, such as a fan of a gas turbine engine, comprises blades 2 and annulus fillers 4 which extend between adjacent blades 2. Gaps 22 between each blade 2 and the adjacent annulus fillers 4 are sealed by sealing elements 8. The sealing elements 8 fit closely around the profile of the blade 2 and have annulus filler sealing surfaces 18 for sealing contact with the annulus fillers 4. The sealing elements 8 have low-friction blade sealing surfaces 12 so that, when the fan is rotating, centrifugal loading displaces the sealing elements 8 radially outwardly so that the annulus filler sealing surface 18 make sealing contact with the annulus fillers 4.</p> |
