Furling (Stargate)
The mythology of the ''Stargate'' franchise is the historical backstory of the ''Stargate'' premise, which centers around xeno-mythology as experienced by humans during episodic contact. In the fictional universe of the franchise, the people of Earth have encountered numerous extraterrestrial races on their travels through the Stargate. In addition to a diversity of alien life, there is also an abundance of other humans, scattered across the cosmos by advanced aliens in the distant past. Some of the most significant species or beings in ''Stargate SG-1'' are the Goa'uld, the Asgard, and the Replicators. '' Stargate Atlantis'', set in the Pegasus galaxy, introduced the Wraith and the Asurans. One of the most influential species in ''Stargate'', the Ancients, have moved on to a higher plane of existence. For practical reasons of television productions, almost all of the alien and human cultures in the Stargate's fictional universe speak native English. Because of the time co ...

Furl (sailing)
Furling refers to stowing or dousing a boat's sail by flaking (folding), packing (like stuffing a spinnaker A spinnaker is a sail designed specifically for sailing off the wind on courses between a reach (wind at 90° to the course) to downwind (course in the same direction as the wind). Spinnakers are constructed of lightweight fabric, usually n ... into a bag), or stowing it in part or whole using roller furling. Furling is not synonymous with ''dousing'' (dropping) or reefing (reducing the exposed area of) a sail, but modern technologies such as roller furling are altering the term's traditional use.

Airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. Foils of similar function designed with water as the working fluid are called hydrofoils. The lift on an airfoil is primarily th ...
