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.
