Abstract (en)
[origin: EP2767678A1] The impeller has wheel disc with disk element (2) having entrance side (3) and exit side (4). The circumference of wheel disc is distributed with axial grooves (5) and several blades (6) having blade root (7). Two plant metal sheets (12) are provided at exit and entrance sides so that exit-side blade root face surface (9) and entry-side blade root face surface (8) of blade root are partially rested against respective plant metal sheets. The disk element is connected with second plant metal sheet by radial connector (15) so that blade root is fixed in radial outer position in groove. An independent claim is included for method for manufacturing blade.
