fan blade

Air-pushing paddle piece

A fan blade is one of the angled surfaces that rotate around a central hub to move air or other fluids.

The blades' pitch and shape determine airflow efficiency.

Fan blades appear in ceiling fans, computer cooling systems, jet engines, and industrial ventilation: The fan blade cracked and sent the whole unit wobbling.
