FIELD: machine engineering.
SUBSTANCE: rotor blade of axial turbine machine contains an aerodynamic part and a platform for its attaching to the rotor. Along the main axis of the blade, the platform comprises a first layer forming a surface which limits fluid flow, and a second layer positioned below the first layer with respect to the aerodynamic surfaces. At that the second layer is designed to interface with the inner surface of the rotor wall around the hole in the said rotor for its connection. A blade rotor is also provided.
EFFECT: invention allows to realise an easy and simple method for connecting blades to the compressor drum.
