Abstract

In a first aspect, there is a method of making a rotor blade (101), including designing at least one of an upper skin (119), a lower skin (121), a support network (123), and components therefor; and forming at least one of the upper skin (119), the lower skin (121), a support network (123), and components therefor using an additive manufacturing process. In a second aspect, there is an airfoil member having a root end (103), a tip end (105), a leading edge (107), and a trailing edge (109), the airfoil member including an upper skin (119); a lower skin (121); and a support network (123) having a plurality of interconnected support members (123) in a lattice arrangement and/or a reticulated arrangement, the support network (123) being configured to provide tailored characteristics of the airfoil member. Also provided are methods and systems for repairing an airfoil member.
