• Energy yield and thrust load<br />
are roughly proportional to<br />
swept area (D 2 )<br />
• Treating <strong>the</strong> blades and tower<br />
as simple beams, and scaling<br />
all dimensions in proportion to<br />
D, you find that stress remains<br />
about <strong>the</strong> same, but mass<br />
changes with D 3 .<br />
(Neglects self-weight, which<br />
becomes more important for<br />
large D)<br />
