Floatplanes
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call floatplanes "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, has greatly reduced the number of flying boats being built. However, many modern civilian aircraft have floatplane variants, most offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found their niche as one type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nakajima A6M2-N
The Nakajima A6M2-N (Navy Type 2 Interceptor/Fighter-Bomber) was a single-crew floatplane based on the Mitsubishi A6M Zero Model 11. The World War II Allied names for Japanese aircraft, Allied reporting name for the aircraft was Rufe. Design and development While waiting on the completion of the Kawanishi N1K, Nakajima was chosen by the Imperial Japanese Navy to provide an interim floatplane, which they did by modifying Mitsubishi's A6M-2 Model 11. Mitsubishi was not offered the contract as they were already overburdened. Nakajima proposed that they could churn out 900 aircraft in under a year. The design of the plane itself wasn't much different than the A6M-2 it was based on. The retractable, wheeled undercariage was removed and plated over. This was replaced by a large central float and one cantilever stablizer float under each wing. The tail was straightened out and the under fuselage received a type of two-section "keel" designed to counteract movement by the central float. ...

Seaplane
A seaplane is a powered fixed-wing aircraft capable of takeoff, taking off and water landing, landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to Hydroplane (boat), motor-powered watercraft that use the technique of Planing (boat), hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplanes ...

List Of Flying Boats And Floatplanes
The following is a list of seaplanes, which includes floatplanes and flying boats. A seaplane is any airplane that has the capability of landing and taking off from water, while an amphibian is a seaplane which can also operate from land. (They do not include rotorcraft, or ground-effect vehicles which can only skim along close to the water) A flying boat relies on its main hull for buoyancy, while a floatplane has a conventional aircraft fuselage fitted with external floats. In some locales, the term "seaplane" is used as a synonym for floatplane. List A small number of seaplanes have retractable beaching gear, which is not capable of being used for landings and takeoffs, but these remain flying boats or floatplanes and are not amphibians. Many floatplanes, especially those since 1945, can have either conventional floats for operating just from water, or amphibious floats, which have retractable undercarriage built into them. Some experimental flying boats have used skis or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially, a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though somet ...

Torpedo Bomber
A torpedo bomber is a military aircraft designed primarily to attack ships with aerial torpedoes. Torpedo bombers came into existence just before the World War I, First World War almost as soon as aircraft were built that were capable of carrying the weight of a torpedo, and remained an important aircraft type until they were rendered obsolete by anti-ship missiles. They were an important element in many famous World War II, Second World War battles, notably the United Kingdom, British Battle of Taranto, attack at Taranto, the sinking of the German battleship German battleship Bismarck, ''Bismarck'', the sinking of the British battleship ''HMS Prince of Wales (53), HMS Prince Of Wales'' and the British battlecruiser ''HMS Repulse (1916), HMS Repulse'' and the Japanese attack on Pearl Harbor. Types Torpedo bombers first appeared immediately prior to the First World War. Generally, they carried torpedo, torpedoes specifically designed for air launch, which were smaller and lighte ...

Boarding (transport)
Boarding is the entry of passengers onto a vehicle, usually in public transportation. Boarding starts with entering the vehicle and ends with the seating of each passenger and closing the doors. The term is used in road, rail, water and air transport (for example, passengers board a coach). Aviation At commercial airports, a ''boarding call'' on the public announcement system asks travelers to proceed to the departure gate and board the aircraft. This can begin any time from an hour to thirty minutes before departure (depending on the size of the plane and number of passengers). For boarding an aircraft, airstairs or jetways are used. Small aircraft may carry their own stairs. Airlines control the access to the aircraft by checking passengers' boarding passes and matching them with the list of passengers and their identification cards. Many airlines use the IATA standard '' Bar Coded Boarding Passes'' (BCBP) to automate this process. A 2D bar code is scanned and the data are ...

Mooring (watercraft)
A mooring is any permanent structure to which a seaborne vessel (such as a boat, ship, or amphibious aircraft) may be secured. Examples include quays, wharfs, Jetty, jetties, piers, anchor buoys, and mooring buoys. A ship is secured to a mooring to forestall free movement of the ship on the water. An ''anchor mooring'' fixes a vessel's position relative to a point on the bottom of a waterway without connecting the vessel to shore. As a verb, ''mooring'' refers to the act of attaching a vessel to a mooring. The term likely stems from the Dutch language, Dutch verb ''meren'' (to ''moor''), used in English since the end of the 15th century. Permanent anchor mooring These moorings are used instead of temporary anchors because they have considerably more holding power. They cause lesser damage to the marine environment, and are convenient. Where there is a row of moorings they are termed a tier. They are also occasionally used to hold floating docks in place. There are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wave
In physics, mathematics, engineering, and related fields, a wave is a propagating dynamic disturbance (change from List of types of equilibrium, equilibrium) of one or more quantities. ''Periodic waves'' oscillate repeatedly about an equilibrium (resting) value at some frequency. When the entire waveform moves in one direction, it is said to be a travelling wave; by contrast, a pair of superposition principle, superimposed periodic waves traveling in opposite directions makes a ''standing wave''. In a standing wave, the amplitude of vibration has nulls at some positions where the wave amplitude appears smaller or even zero. There are two types of waves that are most commonly studied in classical physics: mechanical waves and electromagnetic waves. In a mechanical wave, Stress (mechanics), stress and Strain (mechanics), strain fields oscillate about a mechanical equilibrium. A mechanical wave is a local deformation (physics), deformation (strain) in some physical medium that propa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing
Landing is the last part of a flight, where a flying animal, aircraft, or spacecraft returns to the ground. When the flying object returns to water, the process is called alighting, although it is commonly called "landing", "touchdown" or " splashdown" as well. A normal aircraft flight would include several parts of flight including taxi, takeoff, climb, cruise, descent and landing. Aircraft Aircraft usually land at an airport on a firm runway or helicopter landing pad, generally constructed of asphalt concrete, concrete, gravel or grass. Aircraft equipped with pontoons ( floatplane) or with a boat hull-shaped fuselage (a flying boat) are able to land on water. Aircraft also sometimes use skis to land on snow or ice. To land, the airspeed and the rate of descent are reduced such that the object descends at a low enough rate to allow for a gentle touch down. Landing is accomplished by slowing down and descending to the runway. This speed reduction is accomplished by r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schneider Trophy
The Coupe d'Aviation Maritime Jacques Schneider, also known as the Schneider Trophy, Schneider Prize or (incorrectly) the Schneider Cup is a trophy that was awarded first annually, and later biennially, to the winner of a race for seaplanes and flying boats. In 1931 Britain met the conditions to retain the Trophy permanently; it is on display at the Science Museum in South Kensington, London. Announced in 1912 by Jacques Schneider, a French financier, balloonist and aircraft enthusiast, the competition offered a prize of approximately £1,000. The race was held twelve times between 1913 and 1931, the year when it was finally won permanently by the British. It was intended to encourage technical advances in civil aviation but became a contest for pure speed with laps over a (usually) triangular course, initially and later extended to . The contests were staged as time trials, with aircraft setting off individually at set intervals, usually 15 minutes apart. The contests were v ...

Air Race
Air racing is a type of motorsport that involves airplanes or other types of aircraft that compete over a fixed course, with the winner either returning the shortest time, the one to complete it with the most points, or to come closest to a previously estimated time. History The first 'heavier-than-air' air race was held on 23 May 1909 in aviation, 1909 - the Prix de Lagatinerie, at the Port-Aviation aerodrome (often called "Juvisy Airfield") in Viry-Châtillon south of Paris, France. Four pilots entered the race, two started, but nobody completed the full race distance; though this was not unexpected, as the rules specified that whoever travelled furthest would be the winner if no-one completed the race. Léon Delagrange, who covered slightly more than half of the ten laps was declared the winner. Some other minor events were held before the ''Grande Semaine d'Aviation de la Champagne'' in 22–29 August 1909 at Reims, France, Reims, France. This was the first major intern ...
