Abstract (en)
[origin: EP2762681A1] The drum has a wall (30) rotated about a rotation axis (14) of a rotor, where the wall forms an annular body (36). A row of rotor blades (24) comprises two annular retaining surfaces (38, 42) that are arranged on an outer surface of the wall. The retaining surfaces are diverged from one another to form a profile, where the profile is radially outwards from the outer surface of the wall. The wall is extended in a straight line along the two retaining surfaces between upstream and downstream ribs (32).
