Abstract
A turbine engine with an outer rotor that circumscribes an inner rotor. The outer rotor includes circumferentially arranged components with a radial outer end and radial inner end. Inner ends of confronting sides of adjacent components include at least one damper element to dampen the relative motion of the components or to provide at least a partial seal between adjacent components.
Claims20
A turbine engine comprising:
- an inner rotor defining and rotating about an axially extending longitudinal axis;
- an outer rotor circumscribing at least a portion of the inner rotor and rotating about the longitudinal axis, wherein the outer rotor rotates about the inner rotor;
- at least one component coupled to and rotating with the outer rotor or the inner rotor, the at least one component comprising a plurality of circumferentially arranged and radially extending component segments, wherein each of the component segments includes a passage segment located at an inner band and extending between and opening onto a first circumferential end to define a first opening and a second circumferential end to define a second opening;
- and
- a damper element comprising a tube extending at least partially into the passage segments of a confronting open pair defined by the first opening and the second opening of adjacent component segments, wherein the damper element includes a spacer located between the adjacent component segments.

A turbine engine comprising:
- a rotor;
- a component coupled to the rotor, the component having a plurality of component segments circumferentially arranged and radially extending from the rotor, each of the plurality of component segments having a passage segment located at an inner band and extending between and opening onto a first circumferential end to define a first opening and a second circumferential end to define a second opening, wherein a confronting open pair is defined by the first opening and the second opening of adjacent component segments of the plurality of component segments;
- and
- a damper element that extends between the confronting open pair, wherein the damper element comprises a tube having a spacer located between the confronting open pair.
