Aerodynamic Performance of a 5-Metre-Diameter Darrieus Turbine with Extruded Aluminum NACA-0015 Blades

摘要

A 5-metre-diameter vertical-axis wind turbine has undergone continued testing since 1976 at the Sandia Laboratories Wind Turbine site. The latest tests of this machine have been with extruded aluminum blades of NACA-0015 airfoil cross section. The results of these tests at several turbine rotational speeds are presented and compared with earlier test results. A performance comparison is made with a vortex/lifting line computational code. The performance of the turbine with the extruded blades met all expectations. (ERA citation 05:025856)
