Bar and channel topography, английский
A local-scale topographic pattern of recurring, small, sinuous or arcuate ridges separated by shallow troughs irregularly spaced across low-relief flood plains(slopes generally 2 -6 %); the effect is one of a subdued, sinuously undulating surface that is common on active, meandering flood plains. micro-elevational differences between bars and channels generally range from <0.5 to 2 m and are largely controlled by the competency of the stream. the ridge-like bars often consist of somewhat coarser sediments compared to the finer textured sediments of the micro-low troughs. compare - meander scroll, meander belt. sw

Deflection, английский
- The deference between a tire's unloaded or free radius and the loaded radius.
- Vertical distance between the chord and the skyline, measured at midspan; frequently expressed as a percentage of the horizontal span length (22).
- The displacement of a structural member or system under load.
- Отклонение
- The ricochet of a ball after it hits a player.
- The tendency of a ship from her true course; the departure of the magnetic needle from its true bearing, when influenced by iron or the local attraction of the mass. in artillery, the deviation of a shot from the direction in which it is fired. the term is usually reserved to lateral deviations, especially those resulting from irregular causes—those constant ones due to the regular motion of rifled projectiles coming under either of the designations “constant deflection,” “derivation,” borrowed from the french, or “drift,” from the americans. these latter, according to the direction usually given to the rifling in the present day, all tend away to the right, though they include some subordinate curves not yet distinctly determined.
- [1] gunnery term for the angle between the line-of-sight to the target and the line-of-sight to which the gun must be pointed to compensate for movement, wind, etc. [2] deviation of a compass needle caused by local magnetic influence, especially on a ship.
- A change in the intended course of a borehole produced intentionally or unintentionally by various conditions encountered in the drill hole or by the operational characteristics of the drilling equipment used. also called deviation.
- Отклонение от прямого направления отклонение магнитной стрелки; отклонение стрелки (приборов)
- See static tire deflection,

Flintlock, английский
This early product of the industrial revolution replaced the slow-match and greatly increased the speed of naval gunfire. the device consists of a spring-powered hammer into which a flint is inserted. when the hammer is released by pulling a lanyard the flint strikes a steel element known as the frizzen, creating a spark which ignites a small quantity of gunpowder sitting in a pan above the touch-hole (vent), this in turn ignites the main charge. in 1778, captain (later rear admiral) sir charles douglas, recommended the use of flintlocks for naval ordnance and, when the admiralty rejected the idea, bought musket locks at his own expense and installed them on his own ship. by 1790 the admiralty had finally been convinced of the superiority of this form of ignition and installed them throughout the navy. (army gunners were yet more conservative and—even though the infantry introduced “brown bess” flintlock muskets in the early 1720s—flintlocks were not adopted for land artillery until thirty years after the navy, and even then the gunners retained their portfires as backup.)
Flettner rotators, английский
During the 1920s, german engineer anton flettner developed a method of ship propulsion based on the magnus effect. magnus had noted that when air flow is perpendicular to a vertical cylinder, the air current simply splits to pass on both sides of the cylinder. however, if the cylinder is rotating, the air current on one side is augmented by the cylinder’s rotation; while the current on the opposite side is slowed down. this creates a pressure differential, which results in a force pushing in one direction. flettner’s experimental prototype, a converted schooner named baden-baden, made a successful trans–atlantic crossing, arriving at new york in may 1926. this led the german naval transport service to commission barbara, a 92 meter (300 foot) vessel, with three flettner rotators mounted vertically on the weather deck. each was 17 meters (55 feet) tall and 4 meters (13 feet) in diameter, driven at 250 rpm by an electric motor. for six years, barbara carried freight and passengers between hamburg and italy. however, with an abundance of low cost fossil fuels, the rotator system was unable to compete with conventional engines and fell into disuse. flettner then turned his attention to aerodynamics, using the magnus principle to create lift. his prototype rotary wing aircraft flew in 1932 and, seven years later, the kriegsmarine (nazi german navy) ordered a more advanced model, the fl-282 kolibri. it flew anti-submarine patrols from surface warships in the baltic, mediterranean, and aegean sea, thus becoming the world’s first operational military helicopter. recently, with rising costs and restricted fuel supplies, interest in the marine system has revived. in august 2008, enercon, one of europe’s biggest wind turbine manufacturers, launched e-ship 1 (this name was only meant to identify the project, but it caught on so well that enercon decided to use it for the actual ship). fuel savings of 30–40 percent are expected, thanks to the auxiliary power of paired 27-meter (89-foot) high, 4-meter diameter, flettner rotators, mounted two forward and two aft. a ship equipped with turbosails looks virtually identical to one with flettner rotators, but operates on a different principle. it is hard to believe that either of these vessels—having tall windcatching elements that cannot be furled—would fare well in a storm.
