Abstract:
A brush seal is disclosed that may include a spring-loaded seal arrangement configured to conform to a wide range of sealing diameters along the length of a rotor of a turbomachine. In particular, the brush seal may be manufactured with free ends configured to overlap and provide a finite amount of radially expandable/contractible play and yet maintain an effective seal. Consequently, the same brush seal design may be used in a range of locations along a rotor length without the need to specifically manufacture separate brush seals for each variance in dimension.
