Aichi E16A
The Aichi E16A ''Zuiun'' (瑞雲 "Auspicious Cloud", Allied reporting name "Paul") was a two-seat reconnaissance seaplane operated by the Imperial Japanese Navy during World War II. Design and development The Aichi E16A originated from a 1939 specification for a replacement for the Aichi E13A, which at that time had yet to be accepted by the Imperial Japanese Navy Air Service (IJNAS).Francillon 1979, p. 284. Disagreements about the requirements in the 14-''Shi'' specification prevented most manufacturers from submitting designs, but in 1941 a new 16-''Shi'' specification was drafted by the IJNAS around the Aichi AM-22 design which had already been made by Aichi engineers Kishiro Matsuo and Yasuhiro Ozawa. The first AM-22, which first got the experimental designation Navy Experimental 16-Shi Reconnaissance Seaplane and later the short designation E16A1, was completed by May 1942 and was a conventional, low-wing monoplane equipped with two floats and had the unusual (for a seap ...

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 Wikimedia project, 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 Magazine, 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".

Type 92 Machine Gun
The was developed for aerial use for the Imperial Japanese Navy in 1932. The Type 92 is a light machine gun and not to be confused with the similarly named Type 92 heavy machine gun. Description It was the standard hand-held machine gun in multi-place IJN aircraft during the most part of the Pacific War. It proved to be seriously inadequate. Aircraft produced in the later part of the conflict often were equipped with weapons such as Type 1 and Type 2 machine guns or Type 99 cannon. Essentially a copy of the shroudless post-World War I aircraft-mounted version of the British Lewis gun, the Type 92 was fed with a 97-round drum magazine and used on a flexible mount. It was chambered in a Japanese copy of the .303 British cartridge. The main external difference between the two models was the trigger guard, and cooling fins around the barrel and gas piston tube. Neither the post-World War I British aircraft Lewis nor the Japanese copy featured the distinctive thick barrel shro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yokosuka Naval Air Group
The was the first aviation unit established by the Imperial Japanese Navy in 1916 and survived until the end of the Pacific War. It was charged with educating and training aviation personnel, practical testing of new aircraft, and tactical research. In the event of an emergency, it was supposed to take charge of the defense of Tokyo Bay, and from February 1944, when the war situation demanded it, the unit was also involved in combat. History The "Naval Aviation Research Committee", which was established in 1912, has laid the foundation for the Imperial Japanese Navy Air Service. With the start of domestic production of aircraft and training of crew members on track, the Air Corps Three Group Plan was established in 1916 in order to further improve aircraft. On 1 April 1916 the Yokosuka Naval Air Group was formed in Oppama, Yokosuka, Kanagawa Prefecture to replace the "Naval Aviation Research Committee". On 1 September 1923 the Great Kanto Earthquake caused great damage to f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Japanese Battleship Hyūga
was the second and last built for the Imperial Japanese Navy (IJN) during the 1910s. Although completed in 1918, she played no role in World War I. ''Hyūga'' supported Japanese forces in the early 1920s during the Siberian intervention in the Russian Civil War. In 1923, she assisted survivors of the Great Kantō earthquake. The ship was partially modernised in two stages in 1927–1928 and 1931–1932, during which her forward superstructure was rebuilt in the pagoda mast style. ''Hyūga'' was reconstructed in 1934–1936, improvements being made to her armour and propulsion machinery. Afterwards, she played a minor role in the Second Sino-Japanese War. Despite the expensive reconstruction, the ship was considered obsolete by the eve of the Pacific War, and did not see significant action in the early years of the war. After the loss of most of the IJN's large aircraft carriers during the Battle of Midway in mid-1942, she was rebuilt with a flight deck replacing the rear p ...

Kōkūtai
A ''Kōkūtai'' () was a term used by the Imperial Japanese Navy Air Service (IJNAS) to designate a military aviation unit, similar to the Air Groups in other air arms and services of the time. (''Group'' in the British Royal Air Force, ''Gruppe'' in the German Luftwaffe, ''Groupe'' in the French Armée de l'Air etc.) A Kōkūtai could be based at land or on board aircraft carriers and could contain up to hundreds of men and aircraft. For example, the famous 343 Kōkūtai was a land based fighter group while the 652nd Kōkūtai was a carrier-based bomber group. Kōkūtai were divided into smaller units called Hikōtai, which were the equivalent of a squadron. Kōkūtai were usually divided into three Hikōtai. In general, most pilots and aircrew in the Imperial Japanese Navy Air Service were non-commissioned officers. The word Kōkūtai is abbreviated with the abbreviation "Ku" (空). 343 Ku, for example, stands for 343 Kōkūtai. In the Imperial Japanese Army Air Service ...

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be ...

Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''prototype'' derives from the Greek , "primitive form", neutral of , "original, primitive", from πρῶτ� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
