While both turbines encountered various early problems (the KaMeWa turbine was once
nearly destroyed due to a sheared yaw drive shaft), they both operated successfully for an
extended period of time.
An up-rated version of the WTS-3, the
Hamilton Standard/KKRV WTS-4
was purchased
by the U.S.
Bureau of Reclamation
(USBR) and installed at a site near Medicine Bow,
Wyoming (Fig. 4-24), under a project managed by the NASA Lewis Research Center. With
its rating of 4 MW, it was the most powerful wind turbine ever built. The Bureau wanted to
examine the possible large-scale use of wind power in connection with hydroelectric
systems. Percy Thomas' ideas were inally being realistically investigated!
Germany
The development of the German
3-MW Growian HAWT
(Grosse Windenergie Anlage)
in 1982 (Fig. 3-35) represented the greatest technological leap of the times, as well as the
highest technological risks [Windheim 1983]. It encompassed just about every advanced
feature yet considered. At 100 m in diameter with a 100-m tall tower, it was the largest
wind turbine ever built at that time. The rotor used two, full-span pitch-controlled, carbon-
ilament blades with a high degree of
coning
. It utilized the downwind rotor coniguration

It was one of
the largest wind turbines ever built, with a 100-m diameter rotor and a 100-m tall tower.
