<P>PROBLEM TO BE SOLVED: To provide a blade having asymmetrical mid-span structure portions and a related bladed wheel structure. <P>SOLUTION: The blade includes a body including an airfoil section, a root at an end of the body for coupling the blade to a hub, a first mid-span structure portion extending from the body, and a second mid-span structure portion extending from the body. The first and second mid-span structure portions extend from the body in an asymmetrical manner. The wheel structure includes a bladed wheel including a plurality of circumferentially spaced blades extending from a hub, and a set of mid-span structures coupling adjacent blades of the plurality of circumferentially spaced blades. The set of mid-span structures are positioned in a non-uniform radial position arrangement. <P>COPYRIGHT: (C)2012,JPO&INPIT |
