Abstract
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 () in a friction fit, and a plurality of ring segments (), whereina free axial path length (a) of a sealing ring segment counter to the direction of through-flow is at least as large as an axial engagement (a) of a rotation locking member () of the outer sealing ring (a≥a), which is free of form fit counter to the direction of through-flow, and/or an axial overhang (a) of a radial mounting rail () of the outer sealing ring (a≥a), and/or an axial offset (a, a) of a sealing fin (); and/ora quotient of a specific clearance sum of the outer sealing ring attached to the housing in a friction fitand 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 housing.
