摘要：A fan blade (30) comprises an airfoil having a generally elliptical top surface (32)and a generally elliptical bottom surface (34). The fan blade (30) has a lower radius of curvature toward its leading edge (36) as compared to a higher radius of curvature toward its trailing edge (38). When mounted to a rotating hub member, elliptical fan
blades (30) may provide air movement at significant efficiencies.电话计费系统
