Abstract
An improved method of forming inner and outer sections of a shroud with an airfoil extending between them includes forming the airfoil and shrouds in sections. An upper or convex section of an airfoil is formed with a radially inner section of the shroud while a concave or lower section of the airfoil is formed with a radially outer section of the shroud. A free end portion of the convex or upper airfoil section is inserted into an opening formed in the outer shroud section while a free end portion of the concave or lower airfoil section is inserted into an opening formed in the inner shroud section. The free end portions of the airfoil sections are then connected with the shroud sections to form a complete airfoil and a portion of the inner and outer shroud sections. Although the convex or upper airfoil section is disclosed herein as being integrally formed with the inner shroud section and the concave or lower airfoil section is disclosed as being integrally formed with the outer shroud section, this relationship is a matter of choice and could be reversed if desired.
