The inner shroud removably fitted to the foot of the vanes in the stator of the compressor section of a gas turbine engine is designed to support a radial brush seal for sealing the adjacent rotor from the engines\s hot gases adjacent the foot of the vanes. The shroud supports a spring damper and this assembly relative to the foot of the stator is critically dimensioned so that the hooks formed in the foot of the stator and in the shroud allow the shroud assembly to be positioned radially and moved axially to be locked into place. A retainer ring circumferentially fitted into the shroud holds the assembly. This allows for easy installation and removal.
