2. Blade physics
2.1 Definition of forces acting on blades
Assume that the wind, blowing in direction Ox is incident on an
obstacle. As shown in figure
2
, the stream lines are deformed to circumvent the obstacle.
At the same time, an area of increased pressure is created windward
of the obstacle, that pressure pushing the stream lines outward. Behind
the obstacle, however, a vacuum is created which is responsible for
the reconvergence of lines. The difference in pressure between the
windward and leeward faces involves the existence of a
pressure
force
