feathered propeller
1feathered propeller — A propeller whose blades have been rotated so that the leading and trailing edges are nearly parallel with the aircraft flight path to stop or minimize drag and engine rotation. Normally used to indicate the shutdown of a reciprocating or… …
2propeller blade angle — Except when feathered, when the angle is approximately 90°, the acute angle between the chord of a propeller and the plane of the rotation. Also called pitch. See blade angle. See also propeller synchrophasing …
3propeller brake — A friction brake used on turboprop engines to prevent the propeller from windmilling in flight after it has been feathered and from rotating when the engine has been shut down. In a free turbine, it prevents prolonged windmilling when the… …
4propeller pitch — The acute angle between the chord of a propeller and a plane perpendicular to the axis of rotation. The three main pitch angles are coarse, fine, and feathered …

10high pitch — The pitch of a propeller blade set at a high angle other than the feathering angle. A propeller blade at a high pitch angle takes a greater bite of air than one at a low pitch. Consequently, a high pitch produces more thrust at a given RPM than a …
