Abstract: Wind turbine rotor blade components including pultruded rods and methods of manufacturing the same are disclosed. More specifically, the rotor blade component includes a plurality of pultruded rods housed within an enclosed primary outer casing. The enclosed primary outer casing includes a hollow interior, a root end, and an opposing tip. As such, each of the plurality of pultruded rods is received within the enclosed primary outer casing and secured therein via a first resin material. Further, an arrangement of the plurality of pultruded rods within the primary outer casing and a relationship of a maximum dimension of each of the plurality of pultruded rods and a maximum dimension of the enclosed primary outer casing are configured to maximize flexibility of the rotor blade component.

Abstract: The present disclosure is directed to methods for manufacturing wind turbine rotor blades and components thereof, e.g. using 3D printing. In one embodiment, the method includes forming a rotor blade structure having a first surface and an opposing, second surface, the first and second surfaces being substantially flat. Another step includes printing a leading edge segment of the rotor blade onto the first surface, wherein heat from the printing bonds the leading edge segment to the first surface. The method also includes rotating the rotor blade structure having the leading edge segment attached thereto. A further step includes printing a trailing edge segment of the rotor blade onto the second surface, wherein heat from the printing bonds the trailing edge segment to the second surface. Another step includes securing one or more fiber-reinforced outer skins to the leading and trailing edge segments so as to complete the rotor blade.

Abstract: A transportation system for transporting rotor blades includes a rotor blade fixture configured to support one or more rotor blades. The rotor blade fixture has a first end, and a second end opposed to the first end. The first end is configured for mounting to a root end of a first rotor blade. The rotor blade fixture has a mid-span support located between about 50% and about 80% of a rotor blade span of the first rotor blade. The mid-span support is configured for supporting a mid-span portion of the rotor blade. The rotor blade fixture is configured to mount to a supporting surface so that a portion of the rotor blade fixture and the first rotor blade overhangs the supporting surface. The one or more rotor blades are supported at the root end and at a mid-span location located between about 50% and 80% of the rotor blade span.
