Method and apparatus for improving the airsealing effectiveness in a turbine engine

摘要

A gas turbine engine having coannular components 22, 30 includes means for receiving and retaining a replaceable brush seal 60 so that the seal bristles impede the leakage of air through an intercomponent gap 41. In the preferred embodiment one of the components is a hollow, cylindrical barrel 30 comprising upper and lower barrel segments and the receiving and retaining means includes a retainer 52. The retainer cooperates with the barrel to define a groove 56 within which the brush seal is trapped radially and axially. The brush seal slides circumferentially within the groove to facilitate seal installation and removal.
