Fokker D.XVI
The Fokker D.XVI (sometimes written as Fokker D.16) was a sesquiplane fighter aircraft developed in the Netherlands in the late 1920s. Development The Fokker D.XVI was a conventional, single-bay sesquiplane with staggered wings braced with V-struts. It featured an open cockpit and fixed undercarriage with a tailskid. The wings were made up of wood spars and ribs with a plywood covering, while the fuselage was of steel tube construction with a fabric covering. Power was provided by an Armstrong Siddeley Jaguar radial engine fitted with a Townend ring. Operational history The Royal Netherlands Army ordered 14 aircraft, which differed from the prototype in having divided main undercarriage units in place of the prototype's cross-axle. Hungary purchased four aircraft with Gnome et Rhône-built Bristol Jupiter engines in place of the Armstrong Siddeley Jaguar engines used on the Dutch machines. Evaluation aircraft were also provided to China, Italy, Roumania and the Royal Nether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Netherlands East Indies Army
The Royal Netherlands East Indies Army ( nl, Koninklijk Nederlands Indisch Leger; KNIL, ) was the military force maintained by the Kingdom of the Netherlands in its colony of the Dutch East Indies, in areas that are now part of Indonesia. The KNIL's air arm was the Royal Netherlands East Indies Army Air Force. Elements of the Royal Netherlands Navy and Government Navy were also stationed in the Netherlands East Indies. History 1814–1942 The KNIL was formed by royal decree on 14 September 1814. It was not part of the Royal Netherlands Army, but a separate military arm specifically formed for service in the Netherlands East Indies. Its establishment coincided with the Dutch drive to expand colonial rule from the 17th century area of control to the far larger territories constituting the Dutch East Indies seventy years later. The KNIL was involved in many campaigns against indigenous groups in the area including the Padri War (1821–1845), the Java War (1825–1830), crushin ...

Fokker Aircraft
Fokker was a Dutch aircraft manufacturer named after its founder, Anthony Fokker. The company operated under several different names. It was founded in 1912 in Berlin, Germany, and became famous for its fighter aircraft in World War I. In 1919 the company moved its operations to the Netherlands. During its most successful period in the 1920s and 1930s, it dominated the civil aviation market. Fokker went into bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912. World War I Fokker capitalized on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Romanian Air Force
The Air Force branch of the Royal Romanian forces in World War II was officially named the (ARR), or the Romanian Royal Aeronautics, though it is more commonly referred to in English histories as the (Royal Romanian Air Force, FARR), or simply (Romanian Air Force). It provided support to land forces, carrying out reconnaissance and mounting air raids between other missions. Insignia The roundel of the ARR was based on the national cockade of Romania. During World War Two, from 1941 to 1944, the national cockade was reduced in size and placed in the center of a four-M cross, the seal of King Michael I of Romania. These crosses came in different types and sizes as there was no standard model. The markings were placed on the fuselage as well as on the upper and lower wings, and the national colours were painted on the tail. According to Axis regulations, the engine cowling, the under-surfaces of the wingtips and a vertical band on the fuselage ahead of the tail were painted in yello ...

Regia Aeronautica
The Italian Royal Air Force (''Regia Aeronautica Italiana'') was the name of the air force of the Kingdom of Italy. It was established as a service independent of the Royal Italian Army from 1923 until 1946. In 1946, the monarchy was abolished and the Kingdom of Italy became the Italian Republic, whereupon the name of the air force changed to Aeronautica Militare. History Beginnings At the beginning of the twentieth century, Italy was at the forefront of aerial warfare: during the colonization of Libya in 1911, it made the first reconnaissance flight in history on 23 October, and the first ever bombing raid on 1 November. During World War I, the Italian ''Corpo Aeronautico Militare'', then still part of the ''Regio Esercito'' (Royal Army), operated a mix of French fighters and locally built bombers, notably the gigantic Caproni aircraft. The ''Regia Marina'' (Royal Navy) had its own air arm, operating locally built flying boats. Founding of the ''Regia Aeronautica'' ...

Royal Hungarian Air Force
The Hungarian Air Force ( hu, Magyar Légierő), is the air force branch of the Hungarian Defence Forces. The task of the current Hungarian Air Force is primarily defensive purposes. The flying units of the air force are organised into a single command; under the Air Command and Control Centre. History 1918 to pre–World War II Following the dissolution of the Austro-Hungarian Monarchy in 1918, a small air arm was established operating surviving aircraft from Hungarian factories and training schools. This air arm became the Hungarian Red Air Force under the short-lived Hungarian Soviet Republic, but was disbanded upon its downfall. World War II Under the Treaty of Trianon (1920), Hungary was forbidden from owning military aircraft. However, a secret air arm was gradually established under the cover of civilian flying clubs. During 1938, as a result of the Bled agreement, the existence of the Royal Hungarian Air Force ( hu, Magyar Királyi Honvéd Légierő (MKHL)), was ...

Republic Of China Air Force
The Republic of China Air Force, retroactively known by its historical name the Chinese Air Force and unofficially referred to as the Taiwanese Air Force, is the military aviation branch of the Republic of China Armed Forces, currently based in Taiwan. The ROCAF was founded in 1920 by the Kuomintang. While its historical name is sometimes used especially in domestic circles, it is not used as often internationally due to the current ambiguous political status of Taiwan and to avoid confusion with the People's Liberation Army Air Force of the People's Republic of China (PRC). Its primary mission is the defense of the airspace over and around the Taiwan area. Priorities of the ROCAF include the development of long range reconnaissance and surveillance networks, integrating C4ISTAR systems to increase battle effectiveness, procuring counterstrike weapons, next generation fighters, and hardening airfields and other facilities to survive a surprise attack.

NACA Cowling
The NACA cowling is a type of aerodynamic fairing used to streamline radial engines installed on airplanes. It was developed by Fred Weick of the National Advisory Committee for Aeronautics (NACA) in 1927. It was a major advance in aerodynamic drag reduction, and paid for its development and installation costs many times over due to the gains in fuel efficiency that it enabled. History and design The NACA cowling enhanced speed through drag reduction while delivering improved engine cooling. The cowling consists of a symmetric, circular airfoil that is wrapped around the engine. In a normal planar airfoil, like a wing, it is the difference in airspeed, and their associated changes in pressure, on the top and bottom of the surface that produces lift. In the case of the NACA cowl, the ring-shaped airfoil is positioned so this lift effect is forward, producing thrust. This thrust does not counteract the total drag of the cowl, but greatly reduces its overall value. The differenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtiss V-1570
The Curtiss V-1570 Conqueror was a 12-cylinder vee liquid-cooled aircraft engine. Representing a more powerful version of the Curtiss D-12, the engine entered production in 1926 and flew in numerous aircraft.Gunston 1989, p. 46. Design and development Designed in 1924 as a military successor to the Curtiss D-12, initially named the Conqueror, it was later given the military designation of V-1570 based on its displacement of 1,570 cubic inches (26 L). The engine featured open-ended cylinder liners (advanced technology for the period) and pressurized liquid cooling. Developments including the use of a supercharger gradually increased power output until reliability problems due to overheating and coolant leaks became apparent. Military funding for further development of the Conqueror was cut in 1932, efforts by Curtiss to market the engine for civil airliners failed and the line was dropped from production.
