CENTRIFUGAL FAN IMPELLER Russian patent published in 2025 - IPC F04D29/30

Abstract RU 2832786 C1

FIELD: mechanical engineering.

SUBSTANCE: invention relates to centrifugal fans and can be used in design of turbomachines, air conditioning and ventilation systems, centrifugal pumps, fans, blowers and compressors. Impeller of a centrifugal fan comprises a disc with blades, wherein the blades are inclined to the plane of the disc, at which the surface of the blade on the pressure side is located at an acute angle relative to the plane of the disc, wherein the inclination of the blades is equal to α(r)=α_p*(r/r_p), where α_p is the angle of inclination of the outlet edge of the blade.

EFFECT: improving aerodynamic efficiency of the impeller of the centrifugal fan, ensuring the technological suitability of the impeller blades, ensuring the simplicity and reliability of the design.
