This book was released on 2005 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluation of Aeroelastically Tailored Small Wind Turbine Blades Final Report Global Energy Concepts, LLC (GEC) has performed a conceptual design study concerning aeroelastic tailoring of small wind turbine blades. The primary objectives were to evaluate ways that blade/rotor geometry could be used to enable cost-of-energy reductions by enhancing energy capture while constraining or mitigating blade costs, system loads, and related component costs. This work builds on insights developed in ongoing adaptive-blade programs but with a focus on application to small turbine systems with isotropic blade material properties and with combined blade sweep and pre-bending/pre-curving to achieve the desired twist coupling. Specific goals of this project are to: (A) Evaluate and quantify the extent to which rotor geometry can be used to realize load-mitigating small wind turbine rotors. Primary aspects of the load mitigation are: (1) Improved overspeed safety affected by blades twisting toward stall in response to speed increases. (2) Reduced fatigue loading affected by blade twisting toward feather in response to turbulent gusts. (B) Illustrate trade-offs and design sensitivities for this concept. (C) Provide the technical basis for small wind turbine manufacturers to evaluate this concept and commercialize if the technology appears favorable. The SolidWorks code was used to rapidly develop solid models of blade with varying shapes and material properties. Finite element analyses (FEA) were performed using the COSMOS code modeling with tip-loads and centripetal accelerations. This tool set was used to investigate the potential for aeroelastic tailoring with combined planform sweep and pre-curve. An extensive matrix of design variables was investigated, including aerodynamic design, magnitude and shape of planform sweep, magnitude and shape of blade pre-curve, material stiffness, and rotor diameter. The FEA simulations resulted in substantial insights into the structural response of these blades. The trends were used to identify geometries and rotor configurations that showed the greatest promise for achieving beneficial aeroelastic response. The ADAMS code was used to perform complete aeroelastic simulations of selected rotor configurations; however, the results of these simulations were not satisfactory. This report documents the challenges encountered with the ADAMS simulations and presents recommendations for further development of this concept for aeroelastically tailored small wind turbine blades.

Download or read book Design and Evaluation of Low-Cost Stainless Steel-Fiberglass-Foam Blades for Large Wind-Driven Generating Systems written by and published by . This book was released on 1982 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the development of a low cost wind turbine blade design based on a stainless steel/fiberglass foam design concept and to evaluate its principle characteristics, its low cost features, and its advantages and disadvantages. A blade structure was designed and construction methods and materials were selected. Complete blade tooling concepts, various technical and economic analysis, and evaluations of the blade design were performed. A study was made to determine the applicability of the blade design concept to various blade lengths in the range of 15 ft. to 200 ft. A test specimen of the spar assembly, including the root end attachment, was fabricated. This 20 ft. long full-scale section will be fatigue tested by NASA. It was concluded that the stainless steel/fiberglass-foam blade concept is a viable design for application to large wind turbine systems. A blade design was completed which meets the requirements for operation on the MOD-OA wind turbine. The design concept is applicable to various length blades. Blades less than 60 feet would use a stainless steel spar and blades of larger size would have a fusion welded carbon steel spar. The design permits a choice of a wide selectivity of air-foil shapes and, because of its modular construction, the design provides producibility and quality in high volume production.
