WebbDescription. Blade pitch, often shortened to pitch, refers to the angle between the propeller blade chord line and the plane of rotation of the propeller. Blade pitch is most often described in terms of units of distance that the propeller would move forward in one rotation assuming that there was no slippage. "Fine" pitch refers to a fine or ... Webb13 feb. 2024 · What is meant by propeller feathering? On most variable-pitch propellers, the blades can be rotated parallel to the airflow to stop rotation of the propeller and reduce drag when the engine fails or is deliberately shut down. This is called feathering, a term borrowed from rowing.
