Abstract
FIELD: power plant engineering; manufacture of fans of axial-flow family. SUBSTANCE: incident flow moves over convex and concave surfaces of blade. Aerodynamic forces on concave surface of blade press flow to blade providing its uninterrupted passing. Resistance to flow is considerably lower than at flow with breakaway which takes place on convex side of blade. Length of path of no-breakaway flow is increased by bringing extremum of curvilinear axis to output edge of blade which increases efficiency both on main design type-size of axial flow fan and on fans with cut blades. EFFECT: increased mean efficiency of axial-flow fans.
