A frictional damper is mechanically attached to a cast stator of the compressor section of a gas turbine engine so that a cantilevered end abuts one of the shrouds to prestress the individual ends of the vanes of the stator, which end is free to move by slotting that shroud between adjacent vanes.

A cast stator having a continuous shroud on one end and a non-continuous shroud on the other end concentrically disposed relative to the continuous shroud, circumferentially spaced vanes mounted between said continuous shroud and non-continuous shroud, a spring-like damper member contiguous to said non-continuous shroud prestressing said non-continuous shroud to load each of said vanes to limit movement thereof, and said spring-like damper member being in frictional engagement with and continuous around the periphery of said non-continuous shroud to dissipate the energy occasioned when said vane moves relative to said spring-like damper member.
