Abstract (en)
[origin: EP2400160A1] The stage has a row of rotor blades (9) respectively provided with platforms (12), and a wall (3) rotationally symmetric with respect to a rotational axis of an axial turbomachine, where the wall forms a hollow body. The wall comprises a web and a support zone (5) that is raised with respect to the web in a direction oriented towards exterior of the hollow body. The support zone has side walls (7) connecting a middle part of the zone with the web. Each platform is assembled with the middle part by single fixation element e.g. tie-down bolt, lockbolt or rivet, or multiple fixation elements.
