Abstract

Die Erfindung betrifft einen Gehäuseabschnitt einer Turbomaschinenverdichter- oder Turbomaschinenturbinenstufe, der einen, insbesondere geschlossenen und kreisringartigen, radial äußeren Mantel aufweist. Der radial äußere Mantel weist radial nach innen erstreckende Stege auf, die gegen den Radius geneigt sind.The invention relates to a housing section of a turbomachinery compressor or turbomachine turbine stage, which has a, in particular closed and annular, radially outer jacket. The radially outer shell has radially inwardly extending webs which are inclined to the radius.
