Stator device for disposition within a given turbine casing of a turbomachine, connection system for a turbmachine, and turbomachine

A stator device for disposition within a given turbine casing of a turbomachine, the stator device comprising:

• on a radially outer side, an axially forward connecting element having a radially inward facing forward connecting surface for connection to a forward receiving surface of the turbine casing and an axially rearward connecting element having a radially outward facing rearward connecting surface for connection to a rearward receiving surface of the turbine casing,
• the rearward connecting surface being pre-curved in a circumferential direction eccentrically with respect to the rearward receiving surface;
• the rearward receiving surface being curved concentrically in the circumferential direction about a centerline of the turbomachine;
• the rearward connecting element having a rearward rib portion extending substantially linearly away from a platform of the stator device and providing the rearward connecting surface at a radially outer end;
• and
• the rib portion being provided at the radially outer end with axially extending projections distributed along the circumferential direction for radially retaining the stator device to the turbine casing.
