FIELD: mechanical engineering; axial-flow fans.
SUBSTANCE: invention relates to axial-flow fan containing hub, great number of cantilevers radially laid from hub, and blade members, each being secured to corresponding cantilever. Cantilevers consist of flexible member with rigidly in bending at which blade members in operation are inclined through angle at which centrifugal forces acting onto blade members neutralize traction forces action onto said blade members.
EFFECT: materially reduced changes in loads and vibrations caused by such changes, increased service life of fan blades and drive mechanism.
