Pileateds normally have no white on the trailing edges of their wings and when perched normally show only a small patch of white on each side of the body near the edge of the wing.

When the chordline is horizontal, the trailing edge has a downward direction and since the air follows the trailing edge it is deflected downward.

But this assertion is false ; it is typically the case that the air parcels traveling over the upper surface will reach the trailing edge before those traveling over the bottom.

In order to arrive at a unique ( physical ) solution, one can apply the Kutta condition, which says that for steady flow the rear stagnation point is coincident with the trailing edge of the airfoil.

The stagnation streamline leaves the airfoil at the sharp trailing edge, according to the Kutta condition.

At the instant when the flow is “ turned on ”, the flow is undeflected downstream of the airfoil and there are two stagnation points on the airfoil ( where the flow velocity is zero ): one near the leading edge on the bottom surface, and another on the upper surface near the trailing edge.

As flow over the airfoil commences, the flow along the lower surface turns at the sharp trailing edge and flows along the upper surface towards the upper stagnation point.

The flow in the vicinity of the sharp trailing edge is very fast and the resulting viscous forces cause the boundary layer to accumulate into a vortex on the upper side of the airfoil between the trailing edge and the upper stagnation point.

As the starting vortex increases in strength the bound vortex also strengthens, causing the flow over the upper surface of the airfoil to accelerate and drive the upper stagnation point towards the sharp trailing edge.

The upper stagnation point continues moving downstream until it is coincident with the sharp trailing edge ( as stated by the Kutta condition ).

Equal transit-time states that because of the longer path of the upper surface of an airfoil, the air going over the top must go faster in order to catch up with the air flowing around the bottom, i. e. the parcels of air that are divided at the leading edge and travel above and below an airfoil must rejoin when they reach the trailing edge.

The assertion that the air must arrive simultaneously at the trailing edge is sometimes referred to as the " Equal Transit-Time Fallacy ".

Often having the majority of the weight on the inside trailing ski can help compensate for poor technique, as it allows the skier to use the outside ski as a ' buffer ' to control the snow, and to help keeping the outside ski tip above the snow.

As a group they show a huge range in vegetative form, terrestrial or epiphytic, and can be found as tall cane-like plants a metre or so high, clumped or trailing, pendent or climbing, erect or creeping, tufted and tiny, delicate moss-like species that can grow on the thinnest of twigs.

In others, seizure activity can be controlled by medication ; and the affected child develops mentally and physically trailing normal development by one to two years.

A crew that gets a lead of more than a boat's length can cut in front of their opponent, making it extremely difficult for the trailing crew to gain the lead.

In mathematics, a vampire number or true vampire number is a composite natural number v, with an even number of digits n, that can be factored into two integers x and y each with n / 2 digits and not both with trailing zeroes, where v contains all the digits from x and from y, in any order.

** Long trailing breathing tubes or regulator hoses may snag on things in dark water and can easily be grasped and pulled.

The section lift coefficient for a given angle of attack can be approximated using the thin airfoil theory, or determined from wind tunnel tests on a finite-length test piece, with end-plates designed to ameliorate the three-dimensional effects associated with the trailing vortex wake structure.

Tapered wings with straight leading and trailing edges can approximate to elliptical lift distribution.

* The significance of trailing zeros in a number not containing a decimal point can be ambiguous.

As mentioned before, applications with well-defined bandwidth needs can use up to seven domains of one or more contentionless guaranteed time slots, trailing at the end of the superframe.

In addition, the concave trailing edge enables the kite to be sheeted out further than a traditional C-kite, which is why a Bow kite can be nearly 100 % depowered.

No ringers, either -- even if they are trailing legitimate invitees.

This type of offense forces defenders to commit to either the running back up the middle, the quarterback around the end, or the running back trailing the quarterback.

Other German experiments with JATO were aimed at assisting the launch of interceptor aircraft such as the Messerschmitt Me 262C, as the Heimatschützer special versions, usually fitted with either a version of the Walter HWK 109-509 liquid fuelled rocket engine from the Me 163 Komet program either in the extreme rear of the fuselage or semi -" podded " beneath it just behind the wing's trailing edge, to assist its Junkers Jumo 004 turbojets, or a pair of specially rocket-boosted BMW 003R combination jet-rocket powerplants in place of the Jumo 004s, so that the Me 262C Heimatschützer interceptors could reach enemy bomber formations sooner.

Drum brakes are typically described as either leading / trailing or twin leading.

* Space ( though trailing spaces in either the base name or the extension are considered to be padding and not a part of the filename, also filenames with spaces in them could not be used on the DOS command line because it lacked a suitable escaping system )
