Koolhoven FK.50
The Koolhoven F.K.50 was a 1930s Dutch eight-passenger light transport monoplane designed and built by Koolhoven. Development The F.K.50 was designed to meet a requirement from the Swiss airline Swiss Alpar for a light transport capable of operating in Switzerland. The F.K.50 was a cantilever high-wing cabin monoplane with a fixed wide track tailwheel landing gear. The fuselage was of welded steel tube construction, covered with fabric. The tailplane was of similar construction. The wings were wooden construction, covered with plywood. It was powered by two Pratt & Whitney Wasp Junior T1B engines and had a conventional single fin and rudder. The first of two aircraft first flew on the 18 September 1935 and the second flew in March 1936. A third aircraft, designated F.K.50A, was built in 1938 with a re-designed tail unit with twin vertical tail surfaces. It had a longer nose and larger mainwheels, with a higher all-up weight. Two bomber variants, designated F.K.50B, were propo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

World War II
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), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft First Flown In 1935
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

1930s Dutch Airliners
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Koolhoven Aircraft
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.

Illustrated Encyclopedia Of Aircraft
The ''Illustrated Encyclopedia of Aircraft'' was a weekly partwork magazine by Aerospace Publishing (an imprint of Orbis Publishing) which was published in the United Kingdom (and sold in other countries too) during the early 1980s. The magazine was intended to eventually make up a multi-volume encyclopedia dedicated to aviation. First issued in 1981, the partwork comprised 216 issues, each of twenty pages (plus the covers), making up eighteen volumes (4280 pages). The first two issues were sold together for the price of one, subsequent issues were sold on their own. Empty binders for each volume (of twelve issues) were also sold. These binders were dark blue in colour and contained the imprint of a Panavia Tornado on the front. They held the issues using a metal strip that was threaded through the staples of each issue to hold them in place. Each issue consisted of four separate sections. The final two parts (215 and 216), issued in 1985, comprised the index for the encyclopedi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney Wasp Junior T1B
The Pratt & Whitney R-985 Wasp Junior is a series of nine-cylinder, air-cooled, radial aircraft engines built by the Pratt & Whitney Aircraft Company from the 1930s to the 1950s. These engines have a displacement of ; initial versions produced , while the most widely used versions produce . Wasp Juniors have powered numerous smaller civil and military aircraft, including small transports, utility aircraft, trainers, agricultural aircraft, and helicopters. Over 39,000 engines were built, and many are still in service today. Design and development Pratt & Whitney developed the R-985 Wasp Junior as a smaller version of the R-1340 Wasp to compete in the market for medium-sized aircraft engines. Like its larger brother, the Wasp Junior was an air-cooled, nine-cylinder radial, with its power boosted by a gear-driven single-speed centrifugal type supercharger. Its cylinders were smaller, however, with a bore and stroke of , giving a 27% lesser total displacement. The Wasp Junior used ...

Croydon Airport
Croydon Airport (former ICAO code: EGCR) was the UK's only international airport during the interwar period. Located in Croydon, South London, England, it opened in 1920, built in a Neoclassical style, and was developed as Britain's main airport, handling more cargo, mail, and passengers than any other UK airport at the time. Innovations at the site included the world's first air traffic control and the first airport terminal. During World War II the airport was named RAF Croydon as its role changed to that of a fighter airfield during the Battle of Britain; and in 1943 RAF Transport Command was founded at the site, which used the airport to transport thousands of troops into and out of Europe. After the Second World War, its role returned to civil aviation, but the role of London's primary international airport passed to London Heathrow Airport. Croydon Airport closed in 1959. It had been known under eight different names while it was active. In 1978, the terminal buildin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
