ABSTRACT:
A blade of the fan wheel of a diagonal-flow fan, which blade should ideally have a shape of a twisted double-curvature or undevelopable surface, is formed from a portion of a combination of a cylindrical plate and a planar plate tangent to the cylindrical plate or of a combination of a pair of mutually circumscribing cylindrical surfaces, which portion constitutes a developable surface. To realize the formation of a blade from the developable surface, lines of intersection between combined cylinder and planar plates or combined cylinders and a number of coaxial imaginary conical surfaces representing streamlines in the fan wheel are used as a basis for design.
