Horizontal Axis Wind Turbine
The aerodynamics of a horizontal-axis wind turbine (HAWT) are not straightforward. The air flow at the blades is not the same as the airflow further away from the turbine. The very nature of the way in which energy is extracted from the air also causes air to be deflected by the turbine. In addition the aerodynamics of a wind turbine at the rotor surface exhibit phenomena that are rarely seen in other aerodynamic fields.

Famous quotes containing the words horizontal, axis and/or wind:
“True. There is
a beautiful Jesus.
He is frozen to his bones like a chunk of beef.
How desperately he wanted to pull his arms in!
How desperately I touch his vertical and horizontal axes!
But I can’t. Need is not quite belief.”
—Anne Sexton (1928–1974)
“Our security depends on the Allied Powers winning against aggressors. The Axis Powers intend to destroy democracy, it is anathema to them. We cannot provide that aid if the public are against it; therefore, it is our responsibility to persuade the public that aid to the victims of aggression is aid to American security. I expect the members of my administration to take every opportunity to speak to this issue wherever they are invited to address public forums in the weeks ahead.”
—Franklin D. Roosevelt (1882–1945)
“The King o’ Scots, and a’ his power
Canna turn Arthur O’Bower.”
—Unknown. The Wind (l. 3–4)
