Amphibious Automobile
An amphibious automobile is an automobile that is a means of transport viable on land as well as on or under water. They are unarmored for civilian use. ATVs Amongst the smallest non air-cushioned amphibious vehicles are amphibious ATVs (all-terrain vehicles). These saw significant popularity in North America during the 1960s and early 1970s. Typically an amphibious ATV (AATV) is a small, lightweight, off-highway vehicle, constructed from an integral hard plastic or fibreglass bodytub, fitted with six (sometimes eight) driven wheels, with low pressure, balloon tires. With no suspension (other than what the tires offer) and no steering wheels, directional control is accomplished through skid-steering – just as on a tracked vehicle – either by braking the wheels on the side where you want to turn, or by applying more throttle to the wheels on the opposite side. Most contemporary designs use garden tractor type engines, that will provide roughly top speed on land. Constr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birmabright
Birmabright is a trade name of the former Birmetals Co. (Birmabright works in Clapgate Lane, Quinton, Birmingham, UK) for various types of lightweight sheet metal in an alloy of aluminium and magnesium. The alloy was introduced by the Birmid Group in 1929 and was particularly noted for its corrosion resistance. Birmal Boats was created in 1930 for the building of light-alloy boats. Birmetals Ltd was formed in 1936 and during the war produced both copper bearing aluminium alloys and the Birmabright magnesium bearing alloys, mainly for aircraft production. The constituents were from 1% to 7% magnesium, with <1% , and the remainder aluminium. The alloys were provided in different temper conditions. e.g. soft, 1/4 hard, 1/2 hard and were designed to be work hardened e.g. by cold pressing into shape. They do not exhibit age har ...

Volkswagen Schwimmwagen
The Volkswagen ''Schwimmwagen'' (literally "swimming car") was a four-wheel drive amphibious vehicle, used extensively by German ground forces during the Second World War. The ''Schwimmwagen'' is the most-produced amphibious car in history. Prototyped as the Type 128, it entered full-scale production as the Type 166 in 1941 for the ''Wehrmacht''. Development Volkswagen Schwimmwagens used the engine and mechanicals of the VW Type 86 four-wheel drive prototype of the Kübelwagen and the Type 87 four-wheel drive 'Kübel/Beetle' Command Car, which in turn were based on the platform of the civilian Volkswagen Beetle. Erwin Komenda, Ferdinand Porsche's first car-body designer, was forced to develop an all-new unitized bodytub structure since the flat floorpan chassis of the existing VW vehicles was unsuited to smooth movement through water. Komenda patented his ideas for the swimming car at the German Patent office. The earliest Type 128 prototype was based on the full-length '' ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tr ...

Flying Car
A flying car or roadable aircraft is a type of vehicle which can function both as a road vehicle and as an aircraft. As used here, this includes vehicles which drive as motorcycles when on the road. The term "flying car" is also sometimes used to include hovercars and/or VTOL personal air vehicles. Many prototypes have been built since the early 20th century, using a variety of flight technologies. Most have been designed to take off and land conventionally using a runway. Although VTOL projects are increasing, none has yet been built in more than a handful of numbers. Their appearance is often predicted by futurologists, and many concept designs have been promoted. Their failure to become a practical reality has led to the catchphrase "Where's my flying car?", as a paradigm for the failure of predicted technologies to appear. Flying cars are also a popular theme in fantasy and science fiction stories. History Early 20th century In the late 1800s, American immigrant Gustav ...

Amphibious Vehicle
An amphibious vehicle (or simply amphibian), is a vehicle that is a means of transport viable on land as well as on or under water. Amphibious vehicles include amphibious bicycles, ATVs, cars, buses, trucks, railway vehicles, combat vehicles and hovercraft. Classic landing craft are not amphibious vehicles as they do not offer any real land transportation at all, although they are part of amphibious warfare. Ground effect vehicles, such as ''ekranoplans'', will likely crash on any but the flattest of landmasses so are also not considered to be amphibious vehicles. General technical notes Apart from the distinction in sizes mentioned above, two main categories of amphibious vehicles are immediately apparent: those that travel on an air-cushion ( Hovercraft) and those that do not. Amongst the latter, many designs were prompted by the desire to expand the off-road capabilities of land-vehicles to an "all-terrain" ability, in some cases not only focused on creating a tr ...

Amphibious Aircraft
An amphibious aircraft or amphibian is an aircraft (typically fixed-wing) that can take off and land on both solid ground and water, though amphibious helicopters do exist as well. Fixed-wing amphibious aircraft are seaplanes ( flying boats and floatplanes) which are equipped with retractable wheels, at the expense of extra weight and complexity, plus diminished range and fuel economy compared to planes designed specifically for land-only or water-only operation. Some amphibians are fitted with reinforced keels which act as skis, allowing them to land on snow or ice with their wheels up. Design Floatplanes often have floats that are interchangeable with wheeled landing gear (thereby producing a conventional land-based aircraft). However, in cases where this is not practical, amphibious floatplanes, such as the amphibious version of the DHC Otter, incorporate retractable wheels within their floats. Many amphibian aircraft are of the flying boat type. These aircraft, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herzog Conte Schwimmwagen
''Herzog'' (female ''Herzogin'') is a German hereditary title held by one who rules a territorial duchy, exercises feudal authority over an estate called a duchy, or possesses a right by law or tradition to be referred to by the ducal title. The word is usually translated by the English ''duke'' and the Latin ''dux''. Generally, a ''Herzog'' ranks below a king and above a count. Pine, L.G. Titles: How the King became His Majesty. ''Titles in Western Europe.''Barnes & Noble, Inc. 1992, pp. 70-73. . Whether the title is deemed higher or lower than titles translated into English as "prince" (''Fürst'') has depended upon the language, country and era in which the titles coexisted. History ''Herzog'' is not related to '' Herz'' ('heart'), but is derived from German(ic) He(e)r (English: 'army') and zog (ziehen) (English: 'to move' or 'to pull', also: ''in die Schlacht ziehen'' – "to go into battle", related to the modern English verb '' to tug''), a military leader (compare to ...

Hydra Spyder
The Hydra Spyder is an open-top amphibious sportscar which began production in 2006. It is produced and marketed by Cool Amphibious Manufacturers International, LLC. The vehicle can seat four people and has a 500 hp engine in the standard model making it strong enough to pull water skiers. The company claims the vehicle is unsinkable as all cavities in its "hull" are packed with flotation foam. On land the car is driven normally, and when piloted into a body of water, the simple usage of a toggle button on the dashboard will enable the car's aquatic mode. The wheels then "tuck" into the body of the car, simultaneously switching to a different engine, ready to power the car on water. On land, the 3300 pound vehicle gets 16-18 miles per gallon, and can easily be fitted to take an ethanol mix instead of gasoline. Notable competitors include the Gibbs Aquada The Gibbs Aquada is a high speed amphibious vehicle developed by Gibbs Sports Amphibians. It is capable of speeds over on ...

Gibbs Aquada
The Gibbs Aquada is a high speed amphibious vehicle developed by Gibbs Sports Amphibians. It is capable of speeds over on land and on water. Rather than adding wheels to a boat design, or creating a car that floats, the Aquada was designed from the ground up to perform very well in both fields, with over 60 patents covering technical innovations. The Gibbs Aquada was a limited production concept car produced in 2003 and 2004. The Gibbs Aquada is powered by a 2.5L Rover V6 engine. In 2004 Richard Branson, owner of the Virgin Group, used a Gibbs Aquada to set a new record for crossing the English Channel in an amphibious vehicle. Branson cut 4 hours 20 minutes off the previous record of 6 hours, which had stood since the late 1960s. The officially recorded time was 1 hour 40 minutes, 6 seconds. For the August 2004 edition of ''Top Gear'' magazine, journalist Paul Walton drove an Aquada into and around the Monaco harbour during the Grand Prix of Monaco to watch the event fo ...

Amphicar
The Amphicar Model 770 is an amphibious automobile which was launched at the 1961 New York Auto Show, manufactured in West Germany and marketed from 1961 to 1968. Production stopped in 1965. Designed by Hans Trippel, the amphibious vehicle was manufactured by the Quandt Group at Lübeck and at Berlin-Borsigwalde, with a total of 3,878 manufactured in a single generation. A descendant of the Volkswagen Schwimmwagen, the Amphicar offered only modest performance compared to most contemporary boats or cars, featured navigation lights and flag as mandated by the US Coast Guard — and, after operation in water, required greasing at 13 points, one of which required removal of the rear seat. The ''Amphicar'' name is a portmanteau of "amphibious" and "car". Product description (1966 Amphicar Model 770) Engine: Triumph four-cylinder engine of 1147 cc, 8:1 compression ratio, rated at 38.3 bhp Chassis/body Appearance Front undersurface is slightly pointed and sharply ...
