Windmills are fascinating machines, both in their historical significance and in their ability to generate energy. However, their simple appearance is deceptive. The wind’s unpredictable nature and varying speeds make designing a windmill that can withstand strong gusts and still function effectively a difficult task. Engineers have come up with various strategies to mitigate this challenge, such as shutting down the windmill above its rated speed or adjusting the angle of attack of the blades. One of the most effective methods is pitch control, where the angle of the blades is changed to reduce their effectiveness. Building a windmill requires a wide range of skills, from metalworking to CAD/CAM and aerodynamic theory. Despite the challenges, building a windmill is a rewarding endeavor that can provide reliable power.
