Why Do Turbines have 3 Blades?

Описание: Wind turbines are the icons of modern renewable energy, but they all share one specific feature: exactly three blades. In this video, we explain the physics, engineering, and history behind this design choice using real science and aerodynamic principles.

Why Wind Turbines Have 3 Blades: The Physics of Wind Energy Explained | Simple Things Surprising Histories

This documentary style episode from Simple Things Surprising Histories covers the engineering logic behind wind turbine design, comparing different blade configurations to understand why three is the global standard.

Topics covered in this video:
• The difference between old farm windmills and modern turbines
• How turbine blades act like airplane wings to generate lift
• The physics of drag and why more blades aren't better
• The structural dangers of two-bladed turbines (Gyroscopic Precession)
• The phenomenon of "Tower Shadow" and "The Wobble"
• The psychological and aesthetic reasons for the three-blade design
• The balance between cost, efficiency, and stability in green energy
