A propeller's blades, also known as "airscrew blades" or simply "blades," are the curved components that spin around the engine to create thrust and propel an aircraft forward. These blades are designed with a specific pitch angle which determines how much lift is generated during each rotation. The number of blades on a propeller can vary, with common configurations including two, three, or four blades. Proper maintenance and balancing of these blades are crucial to ensure optimal performance and safety in flight.
