pitch angle of the blade
1blade pitch angle — The angle between the chord of the blade and the reference line on the rotor hub …
2pitch angle — i. The angle between the chord line of a propeller blade and the plane of rotation. ii. The angle between the rotor plane and the chord line. iii. The angle between the chord line and a line that is horizontal or parallel to the surface of the… …
3blade twist — i. The undesirable variation in pitch from root to tip caused by aerodynamic loading. ii. The twist built into a propeller or rotor blade. In the case of a propeller, it is to ensure that the pitch angle at the root is greater than the tip. In… …
4Blade pitch — or simply pitch refers to turning the angle of attack of the blades of a propeller into or out of the wind to control the production or absorption of power. Wind turbines use this to adjust the rotation speed and the generated power. A propeller… …
5Pitch — may refer to:In music: * Pitch (music), the property of a sound or musical tone measured by its perceived frequency ** Range (music), the distance from the lowest to the highest pitch a musical instrument can play ** Vocal range, the distance… …
6pitch — pitch1 [pich] n. [ME pich < OE pic < L pix (gen. picis) < IE base * pi , to be fat > FAT] 1. a black, sticky substance formed in the distillation of coal tar, wood tar, petroleum, etc. and used for waterproofing, roofing, pavements,… …
7pitch setting — The propeller blade setting as determined by the blade angle measured in a manner, and at a radius, specified by the instruction manual of the propeller …
8high 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 …
9coarse pitch — Making a large angle between the blade chord and the plane of the propeller disc, thus producing a high forward speed for a given rotational speed. Unlike at takeoff and landing, when forward air speeds are low and the propeller pitch is fine,… …
