Abstract
A rotor (10) has a basic rotor body (12) and a plurality of rotating blades (14) mounted on the basic rotor body (12). The rotating blades (14) in this case are mounted rigidly or non-detachably, in particular, cohesively, on the basic rotor body (12). Thus, at least one rotating blade (14) has at least one integral sealing element (24), by means of which a root intermediate space (22) is sealed in the region of a blade root (20) radially underneath a blade platform (18) of the rotating blade (14). In addition, the invention relates to a method for producing a rotor (10), in particular, for an aircraft engine, in which a plurality of rotating blades (14) is mounted on a basic rotor body (12), wherein at least one rotating blade (14) having at least one integral sealing element (24) is mounted on the basic rotor body (12).
