the tip of the blade
1Tip speed ratio — The tip speed ratio λ (lambda) or TSR for wind turbines is the ratio between the rotational speed of the tip of a blade and the actual velocity of the wind. If the velocity of the tip is exactly the same as the wind speed the tip speed ratio is 1 …
2Blade geometry — The term Blade geometry refers to the physical properties of a sword blade: cross section and taper. Cross Section The cross section of a blade is the primary way of determining its function and place in history. Early Middle Ages Early Viking… …
3Blade — (bl[=a]d), n. [OE. blade, blad, AS. bl[ae]d leaf; akin to OS., D., Dan., & Sw. blad, Icel. bla[eth], OHG. blat, G. blatt, and perh. to L. folium, Gr. fy llon. The root is prob. the same as that of AS. bl[=o]wan, E. blow, to blossom. See {Blow} to …
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… …
5blade radius — The radius of the circle described by the tip of a rotating blade (i.e., the distance from the blade tip to the axis of rotation) …
6Tip — The end of the sword furthest away from the hilt. Most swords taper to a point at the tip, but some blade lines are straight until the very tip. A few swords, such as a U.S. Civil War saber, are curved along their length …
7tip speed — The speed of a rotating airfoil, measured at its tip. It is generally subsonic except for the blade tips and the tips of the centrifugal compressors, which may be supersonic …
8The Zyurangers — are a group of fictional characters who are the protagonists of the Super Sentai series Kyōryū Sentai Zyuranger . They are the five greatest warriors of the five ancient tribes. Barza called them the Holy Warriors of Justice. The first five went… …
9Blade — For other uses, see Blade (disambiguation). Knife blades A blade is that portion of a tool, weapon, or machine with a cutting edge and/or a pointed tip that is designed to cut and/or puncture, stab, slash, chop, slice, thrust, or scrape animate… …
10blade 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… …
