Abstract: A fluid turbine blade and method of fabrication are provided. The fluid turbine blade includes a centrally disposed longitudinal spar having a substantially circumferential cross section. The fluid turbine blade also includes at least one chord stiffener coupled to the longitudinal spar. The fluid turbine blade further includes a torsionally compliant segmented skin coupled to the at least one chord stiffener. The centrally disposed longitudinal spar and the torsionally compliant segmented skin are functionally decoupled to relieve the torsionally compliant segmented skin of one or more of a flapwise load condition, an edgewise load condition and a torsional load condition.

Abstract: A computer-implemented method for generating a computer model of a composite component includes offsetting a projected ply curved surface outwardly along a base surface to define an offset ply curved surface. The method also includes defining a ply drop region of the base surface, the ply drop region includes another area of the base surface that is exterior to a ply curved surface and interior to an offset ply curved surface. A surface mesh is generated based on the ply drop region and the ply curved surface. The method includes generating a node data comprising a plurality of node points relative to the ply drop regions. Moreover, the method includes applying a curved function to the plurality of node points to facilitate forming a smoothed node data across the ply drop region. A ply mesh is generated using the smoothed node data and the surface mesh.
