FIELD: propellers of flying vehicles and snowplanes. SUBSTANCE: propeller blade includes front and rear planes intersecting on trailing edges at angle of γ and surfaces of back and leading edge engageable with them and curved over radii r and ro. Surface of back is curved by radius r determined from formula r=k2v2/ω which is equal in shank to rounding-off radius ro of leading edge at minimum velocity V of incoming flow. EFFECT: enhanced reliability. 2 dwg
