Wind turbines rotor blades are of which type?

Explanation:
Rotor blades on wind turbines are propeller-type blades. In the common horizontal-axis design, the blades resemble airplane propeller blades—long, airfoil-shaped, and twisted along their length to optimize lift. As wind passes over the blade, lift creates rotation of the hub and shaft, turning wind energy into mechanical energy to drive the generator. Vertical-axis designs exist but use different blade configurations, and terms like clipped aren’t used to describe blade type, while adjustable refers to blade pitch control rather than the fundamental blade form.
