Nakajima Aircraft Company
The was a prominent Japanese aircraft manufacturer and aviation engine manufacturer throughout World War II. It continues as the car and aircraft manufacturer Subaru. History The Nakajima Aircraft company was Japan's first aircraft manufacturer, and was founded in 1918 by Chikuhei Nakajima, a naval engineer, and Seibei Kawanishi, a textile manufacturer, as . In 1919, the two founders split and Nakajima bought out Nihon Aircraft's factory with tacit help from the Imperial Japanese Army. The company was renamed Nakajima Aircraft Company in 1919. The company's manufacturing facilities consisted of the following: * Tokyo plant * Musashino plant * Donryu plant * Ota plant, near Ōta Station. Visited by Emperor Shōwa on November 16, 1934. Critically damaged by American bombardment on February 10, 1945. Currently a Subaru Corporation plant for kei trucks. * Koizumi plant, near Nishi-Koizumi station.

Japan
Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north toward the East China Sea, Philippine Sea, and Taiwan in the south. Japan is a part of the Ring of Fire, and spans an archipelago of 6852 islands covering ; the five main islands are Hokkaido, Honshu (the "mainland"), Shikoku, Kyushu, and Okinawa. Tokyo is the nation's capital and largest city, followed by Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, Kobe, and Kyoto. Japan is the eleventh most populous country in the world, as well as one of the most densely populated and urbanized. About three-fourths of the country's terrain is mountainous, concentrating its population of 123.2 million on narrow coastal plains. Japan is divided into 47 administrative prefectures and eight traditional regions. The Greater Tokyo Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Japanese Navy Air Service
The was the air arm of the Imperial Japanese Navy (IJN). The organization was responsible for the operation of naval aircraft and the conduct of aerial warfare in the Pacific War. The Japanese military acquired their first aircraft in 1910 and followed the development of air combat during World War I with great interest. They initially procured European aircraft but quickly built their own and launched themselves onto an ambitious aircraft carrier building program. They launched the world's first purpose-built aircraft carrier, , in 1922. Afterwards they embarked on a conversion program of several excess battlecruisers and battleships into aircraft carriers. The IJN Air Service had the mission of national air defence, deep strike, naval warfare, and so forth. It retained this mission to the end. The Japanese pilot training program was very selective and rigorous, producing a high-quality and long-serving pilot corps, who were very successful in the air during the early p ...

Imperial Japanese Army Air Force
The Imperial Japanese Army Air Service (IJAAS) or Imperial Japanese Army Air Force (IJAAF; ja, 大日本帝國陸軍航空部隊, Dainippon Teikoku Rikugun Kōkūbutai, lit=Greater Japan Empire Army Air Corps) was the aviation force of the Imperial Japanese Army (IJA). Just as the IJA in general was modeled mainly on the German Army, the IJAAS initially developed along similar lines to the Imperial German Army Aviation; its primary mission was to provide tactical close air support for ground forces, as well as a limited air interdiction capability. The IJAAS also provided aerial reconnaissance to other branches of the IJA. While the IJAAS engaged in strategic bombing of cities such as Shanghai, Nanking, Canton, Chongqing, Rangoon, and Mandalay, this was not the primary mission of the IJAAS, and it lacked a heavy bomber force. It did not usually control artillery spotter/observer aircraft; artillery battalions controlled the light aircraft and balloons that operated in thes ...

Tachikawa Ki-94
The Tachikawa Ki-94 was a single-seat fighter-Interceptor aircraft project undertaken by the Tachikawa Aircraft Company and to be operated by the Imperial Japanese Army. The project refers to two aircraft designs: the Ki-94-I and the Ki-94-II, both of which did not advance beyond the mock-up and prototype stage respectively. Design and development Ki-94-I The first was a twin-boom monoplane with two Mitsubishi Ha211 18-cylinder engines, driving two 4-blade propellers in a push-pull configuration. The very heavy armament that should have been mounted on the aircraft (two 37 mm/1.46 in and two 30 mm/1.18 in cannon,. should have been enough to make short work of most US heavy bombers of the era. Notwithstanding the outstanding prospective performance, which however was judged as "unduly optimistic" by the technical department of the Japanese Army Air Force, this design was judged too complex by the technical department and the design was discarded. Ki-94-II ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nakajima Ki-84
The is a single-seat fighter flown by the Imperial Japanese Army Air Service in the last two years of World War II. The Allied reporting name was "Frank"; the Japanese Army designation was . The Ki-84 is generally considered the best Japanese fighter to operate in large numbers during the conflict. The aircraft boasted high speed and excellent maneuverability with an armament (up to two 30 mm and two 20 mm cannon) that gave it formidable firepower. The Ki-84's performance matched that of any single-engine Allied fighter it faced, and its operational ceiling enabled it to intercept high-flying B-29 Superfortress bombers. Pilots and crews in the field learned to take care with the plane's high-maintenance Nakajima Homare engine and a landing gear prone to buckling. The difficulties of Japan's situation late in the war took a toll on the aircraft's field performance as manufacturing defects multiplied, good quality fuel proved difficult to procure, and experienced pilots ...

Nakajima Ki-87
The Nakajima Ki-87 was a Japanese high-altitude fighter-interceptor of World War II. It was a single seat, exhaust-driven turbo-supercharged engined, low-wing monoplane with a conventional undercarriage. Design and development The Ki-87 was developed in response to American B-29 Superfortress raids on the Home Islands. It followed up on earlier research by Nakajima and the Technical Division of Imperial Army Headquarters into boosting a large radial engine with an exhaust-driven turbo-supercharger, which had begun in 1942, well before the B-29 raids began. The efforts of the Technical Division of Imperial Army Headquarters eventually culminated into the Tachikawa Ki-94-I, while the Ki-87 was developed as a fall-back project, using less stringent requirements. Nakajima started in July 1943 with the construction of three prototypes, to be completed between November 1944 and January 1945, and seven pre-production aircraft, to be delivered by April 1945. The Technical Division ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbo-charger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |
Navy 20-shi A Carrier Fighter
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications ( brown-water navy), open-ocean applications ...

Nakajima G10N1
The Nakajima G10N ''Fugaku'' (Japanese: 富岳 or 富嶽, "Mount Fuji") was a planned Japanese ultra-long-range heavy bomber designed during World War II. It was conceived as a method for mounting aerial attacks from Japan against industrial targets along the west coast (e.g., San Francisco) and in the Midwest (e.g., Detroit, Chicago, and Wichita) and the northeast (e.g., New York City and Norfolk) of the United States. Japan's worsening war situation resulted in the project's cancellation in 1944 and no prototype was ever built. Design and development The Fugaku had its origins in " Project Z (bomber project)", a 1942 Imperial Japanese Army specification for an intercontinental bomber which could take off from the Kuril Islands, bomb the continental United States, then continue onward to land in German-occupied France. Once there, it would be refueled and rearmed and make another return sortie. Project Z called for three variations on the airframe: heavy bomber, transport ( ...
