Publication number: 20140271217Abstract: A wind turbine blade internal structure system is disclosed herein. A representative system includes span wise spar elements, thru thickness web elements, and an aerodynamic shell. In particular embodiments, the spars may be constructed of pre-cured planks and either adhesively bonded together or assembled using layers of laminates between planks. The laminate layers may be used for structural purposes either to increase the stiffness of the spar, increase the effective bond area of the spar to the shell, or to form a transition region at the plank termination. The spars can be incorporated into the shell assembly layup. The shear web may contain segmentation along the span wise axis of the blade, splitting the shear web into pressure and suction halves that are joined by a connector element that allows for alignment between the web halves in the span wise, chord wise, and thickens directions. The spar and web design elements discussed herein can be applied to either a segments or monolithic blade assembly.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: MODULAR WIND ENERGY, INC.Inventor: MODULAR WIND ENERGY, INC.

Publication number: 20140154091Abstract: Wind turbine systems and methods are disclosed herein. A representative system includes a wind turbine blade having an inner region that has an internal load-bearing truss structure, and an outer region that has an internal, non-truss, load-bearing structure. In particular embodiments, the truss structure can include a triangular arrangement of spars, and/or can include truss attachment members that connect components of the truss without the use of holes in the spars. Spars can be produced from a plurality of pultruded composite members laminated together in longitudinally extending portions. The longitudinally extending portions can be connected at joints that interleave projections and recesses of each of the spar portions. The blades can include fan-shaped transitions at a hub attachment portion, formed by laminated layers and/or a combination of laminated layers and transition plates.Type: ApplicationFiled: July 26, 2013Publication date: June 5, 2014Applicant: MODULAR WIND ENERGY, INC.Inventors: Myles L.
