Abstract

See full text

The aircraft-engine gas turbine includes an outer sealing ring for sealing an array of rotor blades that can be attached to a housing by a clamping mechanism (80) in a friction fit, and a plurality of ring segments (20i, 201+1), wherein id='REI-00001' date='20201124' a free axial path length (af) of a sealing ring segment counter to the direction of through-flow is at least as large as an axial engagement (a1) of a rotation locking member (10) of the outer sealing ring (af≥a1), which is free of form fit counter to the direction of through-flow, and/or an axial overhang (a2) of a radial mounting rail (23) of the outer sealing ring (af≥a2), and/or an axial offset (a3, a4) of a sealing fin (31, 41); and/orid='REI-00001' a quotient of a specific clearance sum of the outer sealing ring attached to the housing in a friction fit id='REI-00002' date='20201124' and pi is at least as large as a difference between a maximum outer diameter of the outer sealing ring and a minimum inner diameter of the flow channel inlet of the housingid='REI-00002' .
