Windmill - Wikipedia
A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades, specifically to mill grain (), but the term is also extended to windpumps, wind turbines and other applications. The term wind engine is sometimes used to describe such devices.. Windmills were used throughout the high medieval and early modern periods; the
Savonius wind turbine - Wikipedia
The Savonius turbine is one of the simplest turbines. Aerodynamically, it is a drag-type device, consisting of two or three scoops. Looking down on the rotor from above, a two-scoop machine might resemble the letter "S" in cross section.Because of the curvature, the scoops experience less drag when moving against the wind than when moving with the wind.

What's the Difference Between Vertical and Horizontal Wind,
Jul 24, 2021· The blades on a vertical wind turbine see a uniform airspeed along the length of the blade, as well as the same angle of attack, so they can be much simpler in terms of design. The blades on a Darrieus turbine can be simple aerofoils and don’t have a need for complex additions to enhance the aerodynamics.
Optimized Blade Design for Homemade Windmills
The force of the wind against the windmill blade is based on the wind pressure multiplied by the area of the blade facing the oncoming flow. In the event that the blade is tilted at an angle to the oncoming airstream, then the area of the blade exposed to the fluid is reduced by a factor of sinθ.
Vertical-axis wind turbines: what makes them better,
Oct 31, 2014· Each blade captures the wind twice in each rotation; the second time the same wind strikes the backside.

Vertical Axis Wind Turbine: All You Wanted to Know
Apr 22, 2020· Vertical Axis Wind Turbine (VAWT) A wind turbine cannot be a wind turbine unless it has few blades. Likewise, the horizontal axis turbines, vertical axis ones also have a set of blades. But instead of spinning horizontally, they spin vertically. So, the rotational axis of a VAWT is in the vertical direction, and that’s why it got such a name.

Vertical Axis Wind Turbine - an overview | ScienceDirect,
Vertical-axis wind turbines were the first structures developed to produce the electricity, paradoxically in contradiction with the traditional windmill with horizontal axis. They have the advantage of having the control members and the generator at the ground level, which make them so easily accessible.
Propellers | How Things Fly
A wing has nearly the same angle of attack across its entire length. But a propeller blade has a twist, so its pitch angle varies along its length. On a controllable-pitch propeller, the pitch of the entire blade can be altered during flight to give the best performance at different air speeds. This is similar to changing gears with a car or,
