Koolhoven F.K.51
The Koolhoven F.K.51 was a 1930s Dutch two-seat basic training biplane built by the Koolhoven Company. Design and development The Koolhoven F.K.51 was the winning design in a 1935 Dutch government contest for a new trainer. Designed by Frederick Koolhoven the prototype biplane trainer first flew on 25 May 1935. The aircraft was an equal-span biplane designed to use a variety of engines of . It was a two-seater and had a fixed tailwheel undercarriage. The Royal Netherlands Air Force (LVA) ordered 25 aircraft in 1936 and 1937, powered by a Armstrong Siddeley Cheetah V radial engine. A further 29 aircraft were later ordered with Armstrong Siddeley Cheetah IX engine. The Dutch Naval Aviation Service ordered 29 aircraft each powered by a Pratt & Whitney radials. The Royal Dutch East Indies Army bought 38 aircraft between 1936 and 1938 each powered by a Wright Whirlwind. The Spanish Republican government ordered 28 F.K.51s, 11 with Armstrong Siddeley Jaguar IVa radials and 17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Koolhoven
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 FK-58 single-seat monoplane fighter, the FK-50 twin-engine passenger transport, and the FK-41, built in England under licence by Desoutter. History In 1920, aircraft designer Frederick 'Frits' Koolhoven returned from England to his native Netherlands. The postwar years had not been good to him; the 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. The Netherlands, Koolhoven hoped, would be better. But there he found that while the Netherlands' new airline K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dutch East Indies
The Dutch East Indies, also known as the Netherlands East Indies ( nl, Nederlands(ch)-Indië; ), was a Dutch colony consisting of what is now Indonesia. It was formed from the nationalised trading posts of the Dutch East India Company, which came under the administration of the Dutch government in 1800. During the 19th century, the Dutch possessions and hegemony expanded, reaching the greatest territorial extent in the early 20th century. The Dutch East Indies was one of the most valuable colonies under European rule, and contributed to Dutch global prominence in spice and cash crop trade in the 19th to early 20th centuries. The colonial social order was based on rigid racial and social structures with a Dutch elite living separate from but linked to their native subjects. The term ''Indonesia'' came into use for the geographical location after 1880. In the early 20th century, local intellectuals began developing the concept of Indonesia as a nation state, and set the st ...

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-a ...

1930s Dutch Military Trainer Aircraft
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.

List Of Aircraft Of The Spanish Republican Air Force
This is a list of aircraft used by the Spanish Republican Air Force during the Spanish Civil War. Introduction The Second Spanish Republic was proclaimed in 1931 and very soon the republican authorities set up to reform an antiquated military structure that was a financial burden for the Spanish state following the Great Depression. The Spanish Republican Air Force inherited a great number of airplanes from the monarchy, most of which had been used in the Spanish Campaigns in Northern Africa during general Primo de Rivera's dictatorship in the 1920s. Hostile to the republican reforms, and with many of its top echelon officers sympathizing with the far-right movements of Nazi Germany and Fascist Italy, part of the military elite staged a failed coup led by General Sanjurjo in 1934. However, the rebellion led by General Franco against the Spanish Republic in 1936 was more successful and marked the beginning of the Spanish Civil War. While more than half of the aircraft of the Sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Java
Java (; id, Jawa, ; jv, ꦗꦮ; su, ) is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 151.6 million people, Java is the world's most populous island, home to approximately 56% of the Indonesian population. Indonesia's capital city, Jakarta, is on Java's northwestern coast. Many of the best known events in Indonesian history took place on Java. It was the centre of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally. Four of Indonesia's eight UNESCO world heritage sites are located in Java: Ujung Kulon National Park, Borobudur Temple, Prambanan Temple, and Sangiran Early Man Site.

De Kooy Airfield
De Kooy Airfield ( nl, Vliegveld De Kooy) is an airfield south of Den Helder, Netherlands, named after the nearby hamlet De Kooy. It serves as both a civilian airport under the name Den Helder Airport and a naval airport under the name ''Maritiem Vliegkamp De Kooy'' (Dutch for Maritime Aviation Site De Kooy). Most movements on the De Kooy are made by helicopters, bringing workers to and from offshore oilrigs and naval helicopters such as the NH90 of the Naval Aviation Service of the Royal Netherlands Navy. Fixed-wing aircraft visit and operate from the airport alongside. ''Skyline Aviation'' operates from De Kooy, mainly operating business aircraft and also do airwork such as aerial photography for civilian and military contractors. Amongst its fleet of aircraft most noticeable are several Aero L-39 Albatros jets. History The airport was constructed in 1918 for the Royal Netherlands Navy, whose primary base was and still is located in Den Helder. A seaplane base already e ...
