Damping means for a stator assembly of a gas turbine engine

摘要

The clocking modes incidental to the vibrations encountered in the stator assembly in the compressor section of a gas turbine engine are damped by a spring damper formed as a split ring or a ring of equally shaped and sized segments having a pair of working surfaces. The spring damper is generally U-shaped in cross section and is fixed at the apex with one of the working surfaces in frictional engagement with the base of the vanes and the other working surface in frictional engagement with the containment ring attached to the diaphragm of the stator vane for supporting the inner diameter of the vanes.
