Blade Design and Number | WIND power 2.0 2. WIND TURBINE BLADE DESIGN AND NUMBER Traditional windmills come with more blades, a variety of shapes in cross-section, and low efficiency in converting wind into energy. The cross-sections of modern wind turbine blades and airplane wings show convex tops and flat bottoms. When air passes over and under the blade, a faster air flow on the top creates a lower pressure, while the slower air flow on the underside is due to a higher pressure (Bernoulli’s principle).
