Giromill overview

PDF Version Also Available for Download.

Description

The Giromill is a vertical axis wind turbine having straight airfoils whose angles of attack are controlled so as to maximize wind energy conversion. Each airfoil is rocked during a revolution in order to maintain a constant positive angle of attack over one half revolution and a constant negative value over the other half revolution. McDonnell Aircraft Company completed a feasibility study of the Giromill in 1976. Their initial work was followed by model tests in a wind tunnel in 1976 and 1977. Presently the Pump Division of Valley Industries, Inc., is cooperating with McDonnell Aircraft to design, build, and ... continued below

McDonnell Aircraft Company completed a feasibility study of the Giromill in 1976. Their initial work was followed by model tests in a wind tunnel in 1976 and 1977. Presently the Pump Division of Valley Industries, Inc., is cooperating with McDonnell Aircraft to design, build, and deliver a 40-kW (8.9-m/s) Giromill for the US Department of Energy. Delivery to Rocky Flats is scheduled for the end of 1979. In addition to describing the above work, an evaluation of the Giromill concept in terms of some wind energy rules-of-thumb is presented.
