Kawanishi K-8 Transport Seaplane
The Kawanishi K-8 Transport Seaplane was a Japanese single-engined floatplane of the 1920s. Seven were built in 1926 and 1927, and were used to operate airmail services. Design and development In early 1925, Eiji Sekiguchi, chief designer of the aircraft department of ''Kawanishi Kikai Setsakuho'' (Kawanishi Machinery Manufacturing Works), started work on a long-range floatplane for use by ''Nippon Koku K.K.'' the airline subsidiary of Kawanishi on airmail services. The resulting design, the Kawanishi K-8A, was a single-engined monoplane with a fabric covered wooden structure. It was powered by a Maybach Mb.IVa water-cooled inline-engine, as used in Kawanishi's successful K-7 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.

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".

Shoulder-wing
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Kawanishi Aircraft
was a Japanese aircraft manufacturer during World War II. History The company was founded as Kawanishi Engineering Works in 1920 in Hyōgo Prefecture as an outgrowth of the Kawanishi conglomerate, which had been funding the Nakajima Aircraft Company. Kawanishi built its first aircraft, the Kawanishi K-1 Mail-carrying Aircraft in 1921, and set up an airline, ''Nippon Koku K.K.'' (Japan Aviation Co. Ltd) in 1923, designing and building several aircraft for the airline's use. It was forced by the Japanese government to shut down ''Nippon Koku'' in 1929, however, with its routes being transferred to the government-owned ''Nippon Koku Yuso K.K.'' (Japan Air Transport Co. Ltd.) Kawanishi then split off the former Kawanishi Engineering Works, forming ''Kawanishi Kokuki KK'' in 1928, taking all of the Kawanishi Engineering Works' assets.Mikesh and Abe 1990, pp. 124–125. While Kawanishi was best known for its seaplanes, such as the Kawanishi H6K and Kawanishi H8K, H8K flying boats, its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floatplanes
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call "floatplanes" "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, have greatly reduced the number of flying boats being built. However, numerous modern civilian aircraft have floatplane variants, most of these are offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery.

Fukuoka
is the sixth-largest city in Japan, the second-largest port city after Yokohama, and the capital city of Fukuoka Prefecture, Japan. The city is built along the shores of Hakata Bay, and has been a center of international commerce since ancient times. The area has long been considered the gateway to the country, as it is the nearest point among Japan's main islands to the Asian mainland. Although humans occupied the area since the Jomon period, some of the earliest settlers of the Yayoi period arrived in the Fukuoka area. The city rose to prominence during the Yamato period. Because of the cross-cultural exposure, and the relatively great distance from the social and political centers of Kyoto, Osaka, and later, Edo (Tokyo), Fukuoka gained a distinctive local culture and dialect that has persisted to the present. Fukuoka is the most populous city on Kyūshū island, followed by Kitakyushu. It is the largest city and metropolitan area west of Keihanshin. The city was de ...

Osaka
is a designated city in the Kansai region of Honshu in Japan. It is the capital of and most populous city in Osaka Prefecture, and the third most populous city in Japan, following Special wards of Tokyo and Yokohama. With a population of 2.7 million in the 2020 census, it is also the largest component of the Keihanshin Metropolitan Area, which is the second-largest metropolitan area in Japan and the 10th largest urban area in the world with more than 19 million inhabitants. Osaka was traditionally considered Japan's economic hub. By the Kofun period (300–538) it had developed into an important regional port, and in the 7th and 8th centuries, it served briefly as the imperial capital. Osaka continued to flourish during the Edo period (1603–1867) and became known as a center of Japanese culture. Following the Meiji Restoration, Osaka greatly expanded in size and underwent rapid industrialization. In 1889, Osaka was officially established as a municipality. The construc ...

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 ...
