Abstract
A stator vane assembly for a gas turbine engine comprises a plurality of aerofoil sectioned vanes supported from a circumferentially extending support member or casing via a circumferentially extending platform or platforms. Each vane is attached at one end to one said platform which is carried from the supporting member, each platform being relatively flexible so that deflections of its respective aerofoil sectioned vane cause it to deform. The mounting between the platform and the supporting member is such as to damp motion of the platform and thus of the aerofoil sectioned vane; in some instances resilient material may be interposed between the platform and supporting member to provide the damping.
