Norwegian Army
The Norwegian Army () is the land warfare service branch of the Norwegian Armed Forces. The Army is the oldest of the Norwegian service branches, established as a modern military organization under the command of the King of Norway in 1628. The Army participated in various continental wars during the 17th, 18th, and 19th centuries as well, both in Norway and abroad, especially in World War II (1939–1945). From December 1951, much of the Norwegian Army was declared for operations as part of Allied Forces Northern Europe, within the NATO Military Command Structure. History Creation of the Norwegian Army After the Kalmar War broke out in 1611, the Christian IV of Denmark, Danish-Norwegian king, Christian IV tried to revive the leidang, with dire results. As the Norwegian peasantry had not been armed or trained in the use of arms for nearly three centuries, they were not able to fight. The soldiers deserted or were captured. The soldiers had to participate in military drills w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Pole
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the North magnetic pole, Magnetic North Pole. The North Pole is by definition the northernmost point on the Earth, lying antipode (geography), antipodally to the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the North Pole, so any time can be used as the local time. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere. The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about away, though ...

Norge (airship)
The ''Norge'' was a semi-rigid Italian-built airship that carried out the first verified trip of any kind to the North Pole, an overflight on 12 May 1926. It was also the first aircraft to fly over the polar ice cap between Europe and America. The expedition was the brainchild of polar explorer and expedition leader Roald Amundsen, the airship's designer and pilot Umberto Nobile and the wealthy American adventurer and explorer Lincoln Ellsworth who, along with the Norsk Luftseiladsforening, Norwegian Aviation Society (), financed the trip, which was known as the Amundsen-Ellsworth 1926 Transpolar Flight. Design and development ''Norge'' was the first N-class semi-rigid airship designed by Italian aeronautical engineer Umberto Nobile and its construction began in 1923. As part of the sales contract to the Aviation Society, the airship was refitted for Arctic conditions. The pressurised envelope was reinforced with metal frames at the nose and tail, with a flexible tubula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighter-than-air
A lifting gas or lighter-than-air gas is a gas that has a density lower than normal atmospheric gases and rises above them as a result, making it useful in lifting lighter-than-air aircraft. Only certain lighter-than-air gases are suitable as lifting gases. Dry air has a density of about 1.29 g/L (gram per liter) at standard conditions for temperature and pressure (STP) and an average molecular mass of 28.97 g/mol, and so lighter-than-air gases have a density lower than this. Gases used for lifting Hot air Heated atmospheric air is frequently used in recreational ballooning. According to the ideal gas law, an amount of gas (and also a mixture of gases such as air) expands as it is heated. As a result, a certain volume of gas has a lower density as its temperature increases. The temperature of the hot air in the envelope will vary depending upon the ambient temperature, but the maximum continuous operating temperature for most balloons is . Hydrogen Hydrogen, being the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umberto Nobile
Umberto Nobile (; 21 January 1885 – 30 July 1978) was an Italian aviator, aeronautical engineer and Arctic explorer. Nobile was a developer and promoter of semi-rigid airships in the Aviation between the World Wars, years between the two World Wars. He is primarily remembered for designing and piloting the airship Norge (airship), ''Norge'', which may have been the first aircraft to reach the North Pole, and which was indisputably the first to fly across the polar ice cap from Europe to America. Nobile also designed and flew the ''Airship Italia, Italia,'' a second polar airship; this second expedition ended in a deadly crash and provoked an international rescue effort. Early career Umberto Nobile was born in Lauro, in the southern Italian province of Avellino, into a family of small landowners. His father Vincenzo, a civil servant, belonged to the cadet branch of an aristocratic family that had been stripped of its Nobility, titles after the Italian unification over their ...

Royal Norwegian Navy Air Service
The Royal Norwegian Navy Air Service () was alongside the Norwegian Army Air Service the forerunner to the modern-day Royal Norwegian Air Force. History The RNNAS was established on 1 June 1912,Official Norwegian Defence Force websiteThe first military flight in Norway with the maiden flight of the HNoMS Start, piloted by Hans Dons. The founding of the Air Service was based largely on pride. On 19 April 1912 newspapers had reported that a Sweden, Swedish pilot was planning to fly over Moss, Norway, Moss and Horten. Horten was the site of the main base of the Royal Norwegian Navy. Three officers of the Norway, Norwegian submarine HNoMS A-1 (Kobben), ''Kobben'' decided that it would be a shame if they were not able to beat him to it. Later that year, the Maurice Farman biplanes ''Njaal'' and ''Gange Rolf'' were purchased. In 1915 the Navy established its own Marinens Flyvebaatfabrikk, aircraft factory and a flying school. The main flight base was established in Horten. Other n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
