FIELD: engines and pumps.
SUBSTANCE: invention relates to gas turbine production and can be used in first stages of axial fans and compressors. Proposed impeller features airfoil portion with front edge that has its generating line inclined to radial axis and comprises height-variable blades, front edge being divided into three zones, i.e. hub, central and peripheral zones. Note here that, in central zone, generating line is inclined along the flow, while, in hub zone, adjoining central one, said generating line is inclined counter the flow. Note also the remaining part of hub zone features front edge generating line inclined along the flow.
EFFECT: changed pattern of blade vibration variations results in decreased level of dynamic strains in blades and increased aerodynamic damping with deterioration of aerodynamic and acoustic characteristics of impellers.
