An apparatus for dislodging stuck blades in a turbine engine. The apparatus includes a housing, cam structure, and impact structure. The housing is capable of being temporarily secured to a blade disc structure adjacent to a stuck blade to be dislodged. The cam structure is associated with the housing and is adapted to receive an input torque that rotates the cam structure, the cam structure capable of translating the input torque into an impact force, the impact force including a component in a desired direction. The impact structure is associated with the housing and is capable of receiving the impact force from the cam structure and exerting the impact force on a root area of the stuck blade for dislodging the stuck blade from the blade disc structure non-destructively.

A turbine section having a plurality flow path components forming a plurality of guide vane rings and ring segments arranged in axial succession to define a boundary of a hot gas duct. A vane carrier located around the gas duct, and sealing elements extend radially between circumferentially extending grooves in the vane carrier and respective grooves in the flow path components. The sealing elements include radially inner and outer edges, and at least one axially facing side defining a chamfered portion extending to one of the edges to accommodate axial movement of the sealing element about the one edge within a respective groove.
