A ceiling fan's fan blade spins quietly in the living room.

Definition

Noun: - A single flat or curved piece of a fan that rotates to move air: A fan blade is one of the individual, typically angled, surfaces that extend from the hub of a fan. When the fan rotates, these blades push air, creating airflow for cooling or ventilation.

Usage

• This term specifically refers to a single, discrete component of a fan assembly.
• It is commonly used in contexts involving mechanical devices, household appliances, and industrial equipment.

Examples

• Noun:
  • One of the fan blades was bent, causing the ceiling fan to wobble.
  • For safety, always disconnect the power before cleaning the fan blades.
  • The engineer inspected each fan blade for cracks or damage.

Advanced Usage

• Technical Context: In engineering, the design, pitch, and material of a fan blade are critical for determining the fan's efficiency, airflow, and noise level.
  • The new composite material made the fan blade both lighter and stronger.

Variants and Related Words

• Blade: A more general term for the flat, cutting part of a tool or a similar flat part on a propeller, turbine, or fan.
• Propeller blade: A similar rotating airfoil used to propel an aircraft or boat.
• Impeller blade: A blade on a rotor used to increase the pressure and flow of a fluid within a pump or compressor.

Synonyms

• Vane: Often used interchangeably in some mechanical contexts, though a vane can also be a stationary guide.
• Airfoil: A technical term describing the shaped surface (like a fan blade) designed to generate lift or change airflow.

Related Phrases
