Kentfield, J A.C.

The need for speed-control devices, to prevent rotor overspeeding in strong winds, is examined and the features of classical blade-feathering systems for horizontal axis wind-turbines are reviewed briefly. After consideration of the advantages, and problems, of building slow or medium speed wind-turbines sufficiently robustly to withstand gale force winds head-on two distinct, automatic, speed control systems are described. Each was tested, in model form, under laboratory conditions in a wind-tunnel. 6 refs.
