Flugan
Flugan (''The Fly'') was an early aeroplane designed and built by Carl Richard Nyberg outside his home in Lidingö, Sweden. Construction started in 1897 and he kept working on it until 1922. The craft only managed a few short jumps and Nyberg was often ridiculed, however several of his innovations are still in use.Sundbybergs Museum He was the first to test his design in a and the first to build a .Arlanda Flygsamlingar [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Richard Nyberg
Carl Richard Nyberg (28 May 1858 – 25 March 1939) was a Swedish inventor and industrialist. Nyberg was a pioneer in mechanical engineering. He received a patent for a blow lamp and was an aviation pioneer. Biography Nyberg was born at Arboga in Västmanland, Sweden. After school he started working for a jeweller and later he moved to Stockholm and worked with various metalworks. He later worked for Johan Erik Erikson (1838-1883) at J. E. Eriksons mekaniska verkstad. While working there he had the idea of the blowtorch. He later worked on the idea and created a blowtorch with strong, directed heat and with several safety measures. In 1882 he set up a workshop at Luntmakargatan in Stockholm making blowtorches. However the business didn't work well because it took too long to both manufacture and sell. In 1884 he moved his workshop to Sundbyberg. In 1886, he met Max Sievert (1849–1913) who had founded AB Sieverts Kabelverk in Sundbyberg. Sievert became interested in Nyberg' ...

Hangar
A hangar is a building or structure designed to hold aircraft or spacecraft. Hangars are built of metal, wood, or concrete. The word ''hangar'' comes from Middle French ''hanghart'' ("enclosure near a house"), of Germanic origin, from Frankish *''haimgard'' ("home-enclosure", "fence around a group of houses"), from *''haim'' ("home, village, hamlet") and ''gard'' ("yard"). The term, ''gard'', comes from the Old Norse ''garðr'' ("enclosure, garden"). Hangars are used for protection from the weather, direct sunlight and for maintenance, repair, manufacture, assembly and storage of aircraft. History The Wright brothers stored and repaired their aircraft in a wooden hangar constructed in 1902 at Kill Devil Hills in North Carolina for their glider. After completing design and construction of the ''Wright Flyer'' in Ohio, the brothers returned to Kill Devil Hills only to find their hangar damaged. They repaired the structure and constructed a new workshop while they waited for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

Steam-powered Aircraft
A steam-powered aircraft is an aircraft propelled by a steam engine. Steam power was used during the 19th century, but fell into disuse with the arrival of the more practical internal combustion engine at the beginning of the pioneer era. Steam power is distinct from its use as a lifting gas in thermal airships and early balloons. History * 1842: The Aerial Steam Carriage of William Samuel Henson and John Stringfellow was patented, but was never successful, although a steam-powered model was flown in 1848. * 1852: Henri Giffard flew a 3-horsepower (2 kW) steam-powered dirigible over Paris; it was the first powered aircraft. * 1861 Gustave Ponton d'Amécourt made a small steam-powered craft, coining the name helicopter. * 1874: Félix du Temple flew a steam-powered aluminium monoplane off a downhill run. While it did not achieve level flight, it was the first manned heavier-than-air powered flight. * 1877: Enrico Forlanini built and flew a model steam-powered helicopter ...

C R Flugan
C, or c, is the third letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''cee'' (pronounced ), plural ''cees''. History "C" comes from the same letter as "G". The Semites named it gimel. The sign is possibly adapted from an Egyptian hieroglyph for a staff sling, which may have been the meaning of the name ''gimel''. Another possibility is that it depicted a camel, the Semitic name for which was ''gamal''. Barry B. Powell, a specialist in the history of writing, states "It is hard to imagine how gimel = "camel" can be derived from the picture of a camel (it may show his hump, or his head and neck!)". In the Etruscan language, plosive consonants had no contrastive voicing, so the Greek ' Γ' (Gamma) was adopted into the Etruscan alphabet to represent . Already in the Western Greek alphabet, Gamma first took a '' form in Early Etruscan, then '' in Classical Et ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeroplane
An airplane or aeroplane (informally plane) is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometersMeasured in RTKs—an RTK is one tonne of revenue freight carried one kilometer. of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled such as drones. The Wright brothers invented and flew the first airplane in 1903, recognized as "the first sustained and controlled heavier-than-air powered flight".

Lidingö
Lidingö, also known in its definite form ''Lidingön'' and as ''Lidingölandet'', is an island in the inner Stockholm archipelago, northeast of Stockholm, Sweden. In 2010, the population of the Lidingö urban area on the island was 31,561. It is the seat of government of the Lidingö Municipality, Stockholm County. Lidingö's qualities have attracted affluent residents such as Björn Ulvaeus, Agnetha Fältskog, Anni-Frid Lyngstad and Benny Andersson of ABBA. Exclusive regions include the coastal region between Mölna and the east tip of the island, Gåshaga, as well as the east tip of the northern part of the horse shoe, called Elfvik. Notwithstanding the fact that many middle-class Swedes have moved to the island, (due to rental apartment construction projects), the inhabitants of the municipality remains the third wealthiest in Sweden after Danderyd and Täby. History Runic inscriptions Two runic inscriptions have been found on Lidingö. The latest, listed in Rundata as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blowtorch
A blowtorch, also referred to as a blowlamp, is an ambient air fuel-burning gas lamp used for applying flame and heat to various applications, usually metalworking. Early blowtorches used liquid fuel, carried in a refillable reservoir attached to the lamp. This is distinct from modern gas-fueled torches burning fuel such as a butane torch or a propane torch. Their fuel reservoir is disposable or refillable by exchange. Liquid-fueled torches are pressurized by a piston hand pump, while gas torches are self-pressurized by the fuel evaporation. The term 'blowtorch' is commonly misused as a name for any metalworking torch but properly describes the pressurized liquid fuel torches that predate the common use of pressurized fuel gas cylinders. Torches are available in a vast range of size and output power. The term blowtorch applies to the obsolescent style of smaller liquid fuel torches. Blowtorches are typically a single hand-held unit, with their draught supplied by a natural dra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...
