FIELD: mechanical engineering; compressors.
SUBSTANCE: according to invention, blades 10,10` are fastened over circumference to disk 1 of rotor of axial-flow compressor being arranged in row along circumference of rotor disk 1. Each blade 10, 10' is provided with shaped root 13 for connection with rotor disk 1 and with device for mounting blades 10, 10' in preset and locking the blades. Said device can be lock the blades in ring socket with shaped profile which is formed along circumference of rotor disk 1. At least one insert slot intersects ring socket to provide fitting of roots 13 of blades 10, 10' and device for mounting blades in preset position and locking the blades in position.
EFFECT: improved mounting and locking of rotor blades.
