  • the blades are pushed into these mounting grooves with a blade root provided with undercuts, wherein a direction of movement of the insertion movement is provided with at least one axial component.
  • the insertion direction is inclined to a rotation axis of the rotor at an angle which is mechanically particularly advantageous for the alignment of the airfoil and the blade root.
  • the mounting grooves for such a blade mounting are not incorporated by means of a turning process in the shaft but are milled into the shaft or produced in any other way.
  • a solid rotor or a substantially integrally formed shaft which is not composed of individual discs axially, it requires the insertion of such trained blade feet in corresponding mounting grooves of a circumferentially extending groove for radial insertion of the blade root before insertion in the mounting groove.
  • the attachment groove opens into the circumferential groove.
  • a circumferential groove and a shaft shoulder can be provided.
  • the separate for each blade mounting grooves are also designed as Tannenbaumnuten.
