    摘要： A fan blade assembly having a plurality of arranged about a central hub having an axis of rotation, the blades projecting from the hub radially outward from the axis of rotation. Each blade has a blade length, with a proximal end attached to the central hub and a distal end radially outward from the central hub. The assembly has at least one vane member with a plurality of vane segments, each vane segment joining a first blade with an adjacent second blade at a place along the blade length located radially inward from the distal end and radially outward from the proximal end of the blades. The assembly further having a plurality of recesses in the central hub adapted to receive the proximal end of blades of an adjacent blade assembly to permit stacking of like assemblies.
