Abstract
A method facilitates assembling a gas turbine engine. The method comprises coupling a seal assembly including a brush seal and a plurality of seal bristles to a first rotatable shaft, and positioning the seal assembly such that the seal bristles contact a second rotatable shaft to facilitate sealing between the first and second rotatable shafts during gas turbine engine operation.

A method for assembling a gas turbine engine, said method comprises:
- positioning a seal assembly including a brush seal and a plurality of seal bristles along a first rotatable shaft;
- positioning the seal assembly such that the seal bristles contact a second rotatable shaft to facilitate sealing between the first and second rotatable shafts during gas turbine engine operation;
- and
- coupling the brush seal to the first rotatable shaft such that the brush seal is retained between an abutment extending from the first rotatable shaft and a fastener assembly.
A seal assembly for a gas turbine engine including a first rotatable shaft and a second rotatable shaft, said seal assembly comprising a brush seal and a plurality of seal projections extending outwardly from said brush seal, said brush seal removably coupled to the first rotatable shaft by a fastener assembly such that said plurality of seal projections contact the second rotatable shaft to facilitate sealing between the first and second rotatable shafts.
A gas turbine engine comprising:
- a first rotatable shaft comprising an abutment;
- a second rotatable shaft;
- and
- a seal assembly extending between said first and second rotatable shafts to facilitate preventing leakage through a gap defined between said first and second rotatable shafts, said seal assembly comprising a brush seal and a plurality of seal projections extending outwardly from said brush seal, said brush seal removably coupled to the first rotatable shaft such that said brush seal is retained between an abutment extending from the first rotatable shaft and a fastener assembly, and such that said plurality of seal projections contact the second rotatable shaft to facilitate sealing between the first and second rotatable shafts.
