Design and development of megawatt wind turbines - Wind Power Generation and Wind Turbine Design - page 253

energy from wind results in rated net power densities on the order of 400 W/m 2
requires confi guring rotor systems such that worse case blade tip defl ections safely
stay clear of support structures, and requires rotor thrust-induced overturning
moments be accounted for every operational possibility and local geotechnical
condition. Today's mainstream 1 3 MW WTs will give way to still larger turbines

with the introduction of more and more advanced materials and technologies.
Machines approaching 10 MW are within the realm of possibility. Successfully
exploiting offshore wind resources in part depends on these larger machines
becoming a reality, demands increased reliability, and the ability to install and
maintain these machines at a price comparable to onshore.
Deriving power from the inexhaustible wind - it is truly a great time for the
engineers that are taking up this challenge and for everyone striving to build a
sustainable future for our heirs.
