Abstract

Die Erfindung betrifft ein Gehäuse für eine thermische Turbomaschine, welches in §zwei Gehäusehälften getrennt ist, wobei jede Gehäusehälfte aus jeweils mindestens zwei Gehäuseteilen (11, 12, 13, 14, 42) aus jeweils unterschiedlichen Werkstoffen besteht. Das Gehäuse ist dadurch gekennzeichnet, dass die mindestens zwei Gehäuseteile (11, 12, 13, 14, 42) mittels eines stoffschlüssigen Fügeverfahrens zusammengefügt sind und die Art des verwendeten Werkstoffes den jeweiligen Temperaturanforderungen und mechanischen Belastungen im Betrieb angepasst ist.

Figure 00000001
The invention relates to a housing for a thermal turbomachine, which is separated into two housing halves, each housing half consisting of at least two housing parts (11, 12, 13, 14, 42) each made of different materials. The housing is characterized in that the at least two housing parts (11, 12, 13, 14, 42) are joined together by means of an integral joining process and the type of material used is adapted to the respective temperature requirements and mechanical loads during operation.
