FIELD: machine building.
SUBSTANCE: drum contains wall, on a whole rotating-symmetrical relatively to rotor axis , and having on a whole bent profile. Wall is intended for several blade rows installation on it. First blades row is made by ring flange, made integrally with wall at top of its profile relatively to the axis. Second row of blades is made directly downstream the first and third blade rows directly upstream the first row is made by one or several slots to fix the blades made on the wall. The first blades row and drum create single assembly excluding any oscillations. Blades securing is mixed. Rotor can be installed in casing with ring stators.
EFFECT: reduced oscillations in rotor of axial turbine machine.
