Abstract

Die Erfindung bezieht sich auf einen Gasturbinenaxialverdichter mit einem Gehäuse 3 und einer drehbaren Welle 5, welche einen Ringkanal bilden, in welchem zumindest ein Stator 2 und ein Rotor 4 angeordnet sind, dadurch gekennzeichnet, dass an einem freien Ende von Statorschaufeln des Stators 2 ein Deckband 21 angeordnet ist, welches sich über einen Teil der axialen Länge des Stators 2 erstreckt und dass ein weiterer Teil der axialen Länge des Stators 2, an welchem kein Deckband 21 angeordnet ist, radial angrenzend an eine von einer Rotornabe 8 gebildete Rotorplattform 28 angeordnet ist.

Figure imgaf001
The invention relates to a Gasturbinenaxialverdichter with a housing 3 and a rotatable shaft 5, which form an annular channel in which at least one stator 2 and a rotor 4 are arranged, characterized in that at a free end of stator blades of the stator 2, a shroud 21, which extends over a part of the axial length of the stator 2, and that a further part of the axial length of the stator 2, on which no shroud 21 is arranged, is arranged radially adjacent to a rotor platform 28 formed by a rotor hub 8.
