Abstract
Official abstract text for this publication.
A device for supporting a ring of a gas turbine, the ring configured to surround mobile blades of the turbine which are driven by a gas stream flowing upstream to downstream. The device includes at least one upstream hook facing upstream, to be housed in an upstream groove of the ring, opened toward the downstream direction, and at least one downstream hook facing downstream, to be housed in a downstream groove of the ring, opened toward the upstream direction. The hooks are protected and clearances at apexes of the blades are more easily controlled. The device further includes, upstream from the upstream hook, a mechanism injecting cooling gas to cool the upstream hook and/or includes, downstream from the downstream hook, a mechanism injecting a cooling gas to cool the downstream hook.
First claim
Opening claim text (preview).
The invention claimed is: 1. A supporting device for a ring of a gas turbine, the ring configured to enclose moving blades of the turbine driven by a gas flow flowing from upstream to downstream, the device comprising: at least one upstream hook, facing upstream, configured to be accommodated in an upstream groove of the ring, which groove is open in the downstream direction; at least one downstream hook, facing downstream, configured to be accommodated in a downstream groove of…
