Abstract

A clearance control device (50) comprising a segment (36) having a passage (44) to deliver fluid towards a component (34) rotating past the segment (36). Also a fluid flow device (52) having a first fluid path (58) coupled to the passage (44) and a second fluid path (60) that is decoupled from the passage (44). A first plasma generator (62) is located in the fluid flow device (52) that directs fluid towards the first fluid path (58); a second plasma generator (64) is located in the fluid flow device (52) that directs fluid towards the second fluid path (60); and a control arrangement (54) is configured to alternately energise the first and second plasma generators (62, 64) at an energising frequency to deliver fluid to the passage (44) at a frequency coincident with the passing frequency of the component (34).
