	Wing Tip Devices: Hoerner Tips, Winglets, Endplates
		Tip devices have become a popular technique to increase the aerodynamic performances of lifting wings, short and slender alike.
		Hoerner tips are crescent-shaped geometries with a slight upward feathering.
		Tip tanks are devices that extend beyond the physical range of the wings and protrude from both the leading-edge and the trailing-edge.

	Vortex-lift roll-control device - Patent 4132375
		A wing, for aircraft of cropped, arrow-type planform with thin leading and side edges, having a pivotable tip to alter the crop angle of the wing during flight.
		The tip control panel possesses a substantially straight tip edge which, when positioned parallel with the longitudinal plane of symmetry of the aircraft, is subject to the vortex flow present there and hence contributes to wing lift.
		Tip control panel 31 is suitably connected to main wing panel 18 for rotation in the wing areal, or planform, plane about a pivot point 23 located within main wing panel 18 near the forward portion of tip section 22 thereof and which is located in the forward portion of tip control panel 31.

		The commonest use of wings is to fly by deflecting air downwards to produce lift, but wings are also commonly used as a way to produce downforce and hold objects to the ground (for example racing cars).
		Rogallo wings are two hollow half-cones of fabric, one of the simplest wings to construct.
		The amount of lift produced by a wing increases with the angle of attack (the angle between the onset flow and the chord line) but this relationship ends once the stall angle is reached.

	Wingtips - What Good Are They? (Site not responding. Last check: 2007-10-03)
		Tip losses vary considerably with different wing configurations; the losses increase in some proportion to the following: higher angle of attack, lower aspect ratio, higher wing loading, lower airspeed, higher sweep angles, and of course the design of the wingtips.
		The first way to cut tip losses is by increasing the Aspect Ratio of the wing; that is, building the wing longer in proportion to its chord, or width.
		Wing tips are an area where you can easily do (and undo) modifications to your plane, to alter some of its performance characteristics.

	Wright Brothers' Wing Warping
		The tips of their wings could by twisted relative to the rest of the wing by a series of cables.
		At the bottom is a slider which lets you change the amount of deflection of the right wing tip or the left wing tip, as viewed from the front of the aircraft.
		There are additional control wires at the rear of the wing which connect the wing tips to a pedal at the foot of the pilot.

	Nasaexplores
		Wing tip, or wake, vortices are very powerful tornado-like disturbances in the air coming off the wing tips of an airplane that trail behind the aircraft.
		Wing tip vortices are a particularly dangerous hazard during approaches or departures from airports since trailing aircraft have little altitude in which to recover.
		With the two spoilers on the outer panels of each wing extended, the vortices were greatly reduced, and the chase aircraft could safely fly 5 kilometers behind the large aircraft, compared to 15 kilometers with no spoilers.

	Aerospaceweb.org \| Ask Us - Boeing 767 Raked Wingtips
		Tips of this type are not often seen because of structural issues.
		Since the tips are so highly swept, the lift force generated by the extensions will act further back than the lift generated by the rest of the wing.
		While this sort of wing "warping" is usually not desirable for structural reasons, perhaps Boeing engineers have used this torsional effect to create an aerodynamic washout.

	Lancair wing tip stalls
		For a wing that is prone to tip stall, it is important that the use of aileron always include use of rudder to correct for adverse yaw.
		Not many aircraft have such sharply tapered wings as to have the tip actually stall first, and in most cases the action described as âtip stallâ is simply an unintentional snap as you said.
		The angle of attack (incidence) of the advancing wing is decreased and on the retreating wing is increased.

	Wing - Wikipedia, the free encyclopedia
		A wing is a surface used to produce an aerodynamic force normal to the direction of motion by traveling in air or another gaseous medium, facilitating flight.
		The most common use of wings is to fly by deflecting air downwards to produce lift, but upside-down wings are also commonly used as a way to produce downforce and hold objects to the ground (for example: racing cars).
		The wings of this cockchafer are clearly visible beneath the elytra.

	Aerodynamics, Non Planar Wing Systems
		Methods for the analysis of such wings have evolved due to the requirements of minimum induced drag (or drag due to lift) for powered aircraft, and later for endurance flight, flight altitude flight and human-powered flight.
		Wings with endplates, winglets and other tip devices belong to the same category of non-planar systems.
		The benefits of using large wing spans are well known from small perturbation theory: The induced drag grows with the inverse of the aspect-ratio.

	Wing Tips
		Wing tip shape has a large input to airplane performance: roll rate, stall speed and landing speed.
		To be able to visualize the flow around the tips, he glued bright red thread glued to the leading edge of the wing.
		The wing tips with the least outward flow should be the most efficient.

	Wing
		The wing shape is formed from two surfaces, an extruded airfoil and a wingtip cap on the end; these two surfaces are then mirrored across the y=0 plane to form the right half of the wing.
		The wing is constructed by first extruding the airfoil in the spanwise direction to a half-span length.
		An example of the wing section difference between the original airfoil and the airfoil modified with a flap cusp for a 60-point NACA 64A410 airfoil is shown in Figure

		This is the case with wing tip protection.
		But it allows the wing tip to nearly touch a flat surface and permits aileron corners to scrub the pavement.
		This is not a shortcoming in the eyes of someone intent on squeezing the last bit of performance from a ship, but now that the Standard Cirrus has been ecclipsed by 30 years of performance improvements, owners are more likely to be concerned with preservation than performance.

	microSAIL! - manufacturer of the most unique, high quality Radio Control sailboats
		The Wing Tip Rig represents a powerful planform for a sail that unlike most modern fully roached or square top rigs does not require full battens (which don't work too well on models).
		The essence of the Wing Tip Rig is better sail shape, drag reduction, and light weight (compared to fully roached sails).
		The first Wing Tip Rig that could be hoisted was first devised by Doug Lord in 1975.

	Wake Turbulance and Wing Tip Vortices
		As the wings of a large airliner pass through the air, lift occurs when the high pressure under the wing tries to fill a vacuum of the low pressure on top of the wing.
		What happens is two vortices (the left wing clockwise and the right wing counterclockwise as viewed from behind the airliner looking forward) develop and continue to spin until their energies are reduced.
		Wing tip vortices start at the moment a "heavy" leaves the ground.

	Largest Lepidopteran Wing Span
		After enlarging the photographs of the two specimens, I estimated the distance from the base of the lower margin of the forewing to the tip of the wing to be 146.2mm and 147.7mm for the specimens from Costa Rica and Brazil, respectively.
		In addition, for the Costa Rica specimen a line from the base of the forewing to the wing tip forms an approximately 65° angle with a line parallel to the midline of the body, thus the distance from the body to the tip on one side is approximately equal to 146.2sin65=132.5mm.
		Consequently, if the Brazil specimen’s wings raised at equivalent angles to the Costa Rica specimen, it would be approximately 1.4mm longer on each side (neglecting a possible slight difference in body widths which would be difficult to estimate from the photos), with a total wing span of approximately 289mm.

		The same reduction in induced drag can be achieved by increasing the span of the wing, however increasing the span increases the structural demands on the wing, and slows down the roll rate.
		A) The winglets attach to the tip of the sail in the same manner as the conventional wing tip fairings - there are velcro surfaces inside the tip of the sail, and on the outside surface of the winglet.
		However, the cut of the sail at the tip will not necessarily place the winglets at the optimum incidence angle on these models, and as a result they may not work as well.

	Wing tip - Wikipedia, the free encyclopedia
		Because the wing tip shape influences the size and drag of the wing tip vortices, tip design has produced a diversity of shapes, including:
		Wing tips are also an expression of aircraft design style and so their shape may be influenced by marketing considerations as well as by aerodynamic requirements.
		Wing tips are often used by aircraft designers to mount navigation lights, anti-collision strobe lights, landing lights and identification markings.

	The Wing Tip
		Select a vertex at the end of the loft and drag it onto its nearest neighbor on the wing; as soon as the mouse pointer changes into a cross, release the mouse button.
		However, the top side of the tip as seen from the back or front looks flat while it should look, well, curved a little (I know this is a fantasy wing, but stick with me):
		So, using a loft can be a rather neat way to build rounded, "golden era" wing tips since it gives you easy and complete control over the most important part: the edge.
