ABSTRACT:
A turbine engine has a rotor shaft rotatably carried within a support structure. A seal is carried by the support structure circumscribing the shaft and having a brushpack for sealing with the shaft. A first plate on a first side of the brushpack has a first radial clearance from the rotor shaft. A rubplate has a radial clearance from the rotor shaft that is less than the first radial clearance when the seal and rotor are coaxial.
