Project Description

SkyDrill Power Systems Vertical Axis Wind Turbine

Prototype Design & Analysis

DARcorporation was involved in the aerodynamic and structural design and prototype testing of the SkyDrill Power Systems Vertical Axis Wind Turbine (VAWT). Because a VAWT is designed to turn at much lower rpms, they will produce energy at lower wind speeds and are more acceptable for urban areas where noise pollution is a concern. Two-Dimensional Computational Fluid Dynamics (CFD) analysis was conducted on various blade profiles to see which profile yielded a better performance. After the blade profile analysis, a series of Three-Dimensional CFD cases were analyzed and studied. The performance parameters were extracted from the results of these CFD cases. Finite Element models were created with load cases from CFD analysis. Normal modes and frequency response of the structure was analyzed using NEi Nastran and Femap.
