FIELD: machine building.
SUBSTANCE: group of inventions relates to an axle compressor blisk and an aircraft gas turbine engine low pressure rotor. Blisk is made in the form of "Half-blisk", or "Double Half-blisk", or "Triple Half-blisk". Blisk—"Half-blisk" is made with half of blades of one step, made as a whole with disc. Blisk—"Double Half-blisk" is made with half blades of two stages, made as a whole with disc. Blisk—"Triple Half-blisk" is made with half blades of three stages, made as a whole with disc. In the "Double Half-blisk" blisk longitudinal axes of grooves for locks of blades of both stages together with blades, made as a whole with blisk, forming inter-blade channel on the wheel, lie on one axis. In the "Triple Half-blisk" blisk longitudinal axes of the same slots, but already three stages, lie on one axis.
EFFECT: group of inventions is aimed at providing effective damping of blisk rotor blades unidirectional vibrations with high repairability.
