Wind Turbine Design & Analysis
DARcorporation has been offering aeronautical engineering software and consulting services since 1991 and is a world class aeronautical engineering and prototype development company that boasts a team of highly skilled aeronautical engineers, software developers, project managers and prototype production personnel. Our primary objective is to help you design, prototype and test your horizontal axis, vertical axis and unconventional wind turbines.
DARcorporation engineers work with customers to solve their most critical problems and combine extensive engineering experience with computerized simulation tools to provide the services our customers want. Through the following disciplines, DARcorporation provides professional services for the design and analysis of wind turbines.
Wind Turbine Design Projects
Based on Blade Element Momentum (BEM) theory, DARcorporation has developed and customized in-house software for initial aerodynamic design of the wind turbine power generating surfaces to handle any type of wind turbine configuration and blade shape. Using high-fidelity computational fluid dynamics (CFD) software with rotation simulation, the full power curve of the wind turbine can be created. Pressure distribution over the blades is calculated and torque (and thus power) curves are constructed. The interaction between the power generating surfaces and the rest of the structure can also be analyzed. The deliverables of aerodynamic design include recommendations on the number of blades, airfoil selection, chord and pitch distribution, rotor diameter, RPM, etc. DARcorporation engineers have the ability to select the ideal generator for your conﬁguration and will perform dynamic startup simulation, so the eﬀects of wind speed changes on your wind turbine energy generation is captured. Services include:
Our engineers use Finite Element Analysis (FEA) methods and software to analyze propeller/rotor and duct structures for strength, stiffness, dynamic modes, fatigue, ﬂutter, etc. Pressure distributions, experimental or analytical, are mapped to the structural model to account for the aerodynamic loads.
Structural analysis software (Femap/Nastran, AFGROW, ZAERO, LS-DYNA, etc.) is used to model and analyze the structure, which can be made of metals (steel, aluminum, etc.), composites (glass, carbon, etc.) or any combination of metals and composites as well as bonded and fastened joints.
Results such as stresses, deformations, buckling factors, natural frequencies, ﬂutter speeds, impact forces, etc. are compared against possible failure modes to ensure structural integrity. Unwanted vibrations are identified and designed out of the system. The structural analysis yields material selections, material thicknesses and composite layup schedules and produces an optimized structural conﬁguration. Services include:
