Koolhoven (aircraft Manufacturer)
N.V. Koolhoven was an aircraft manufacturer based in Rotterdam, Netherlands. From its conception in 1926 to its destruction in the Blitzkrieg in May 1940, the company remained the second major Dutch aircraft manufacturer (after Fokker). Although many of its aircraft were as unsuccessful economically as they were brilliant from a design standpoint, the company managed to score several 'hits', amongst them the Koolhoven FK-58, FK-58 single-seat monoplane fighter, the Koolhoven F.K.50, FK-50 twin-engine passenger transport, and the Desoutter Mk.II, FK-41, built in England under licence by Desoutter. History In 1920, aircraft designer Frederick Koolhoven, Frederick 'Frits' Koolhoven returned from England to his native Netherlands. The postwar years had not been good to him; the British Aerial Transport, British Aerial Transport Company for which he was chief designer went bankrupt and all other manufacturers were struggling for survival too hard to think of hiring.

Koolhoven Heidevogel
The Koolhoven Heidevogel was one of the first Dutch aircraft, an improvement of the popular Farman type. Development Frits Koolhoven began as car dealer and racing driver but his entry into aviation came in partnership with Henri Wijnmalen whose uncle was the Verwey in the motor car manufacturing business, Verwey and Lugard. An aviation department of the latter developed, with Koolhoven dominant in the factory and Wijnmalen running the flying school. The Heidevogel (Heathbird or Heatherbird) was one of several pioneer aircraft based on the Farman III and generally known as "Farman types", though it had several modifications to the wings, rudders and accommodation. It was a multi-bay, unequal span biplane with no stagger and wings of constant chord, braced with pairs of parallel interplane struts. Ailerons provided lateral control. The empennage was supported by an open frame fuselage with longitudinal upper and lower pairs of longerons or booms, each side braced with four v ...

Battle Of France
The Battle of France (french: bataille de France) (10 May – 25 June 1940), also known as the Western Campaign ('), the French Campaign (german: Frankreichfeldzug, ) and the Fall of France, was the German invasion of France during the Second World War. On 3 September 1939, France declared war on Germany following the German invasion of Poland. In early September 1939, France began the limited Saar Offensive and by mid-October had withdrawn to their start lines. German armies invaded Belgium, Luxembourg and the Netherlands on 10 May 1940. Italy entered the war on 10 June 1940 and attempted an invasion of France. France and the Low Countries were conquered, ending land operations on the Western Front until the Normandy landings on 6 June 1944. In ''Fall Gelb'' ("Case Yellow"), German armoured units made a surprise push through the Ardennes and then along the Somme valley, cutting off and surrounding the Allied units that had advanced into Belgium to meet the German armies ...

France
France (), officially the French Republic ( ), is a country primarily located in Western Europe. It also comprises of overseas regions and territories in the Americas and the Atlantic, Pacific and Indian Oceans. Its metropolitan area extends from the Rhine to the Atlantic Ocean and from the Mediterranean Sea to the English Channel and the North Sea; overseas territories include French Guiana in South America, Saint Pierre and Miquelon in the North Atlantic, the French West Indies, and many islands in Oceania and the Indian Ocean. Due to its several coastal territories, France has the largest exclusive economic zone in the world. France borders Belgium, Luxembourg, Germany, Switzerland, Monaco, Italy, Andorra, and Spain in continental Europe, as well as the Netherlands, Suriname, and Brazil in the Americas via its overseas territories in French Guiana and Saint Martin. Its eighteen integral regions (five of which are overseas) span a combined area of and contain clos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also ...

Armstrong Whitworth
Sir W G Armstrong Whitworth & Co Ltd was a major British manufacturing company of the early years of the 20th century. With headquarters in Elswick, Newcastle upon Tyne, Armstrong Whitworth built armaments, ships, locomotives, automobiles and aircraft. The company was founded by William Armstrong in 1847, becoming Armstrong Mitchell and then Armstrong Whitworth through mergers. In 1927, it merged with Vickers Limited to form Vickers-Armstrongs, with its automobile and aircraft interests purchased by J D Siddeley. History In 1847, the engineer William George Armstrong founded the Elswick works at Newcastle, to produce hydraulic machinery, cranes and bridges, soon to be followed by artillery, notably the Armstrong breech-loading gun, with which the British Army was re-equipped after the Crimean War. In 1882, it merged with the shipbuilding firm of Charles Mitchell to form Armstrong Mitchell & Company and at the time its works extended for over a mile (about 2 km) along ...
