Mitsubishi J4M
The Mitsubishi J4M ''Senden'' (閃電 "Flashing Lightning") or Navy Experimental 17-''Shi Otsu'' B Type Interceptor Fighter ''Senden'', Allied reporting name Luke, was a Japanese World War II fighter aircraft proposed by Mitsubishi Heavy Industries for use by the Imperial Japanese Navy. The J4M project did not proceed beyond the design stage. Design and development To provide the Imperial Japanese Navy with a land-based high-performance interceptor aircraft, Mitsubishi designed the J4M. It was to have been a single-seat, twin-boom, low-wing monoplane with a central nacelle housing an unstepped cockpit and a 1,590-kilowatt (2,130-hp) Mitsubishi Ha-43 radial engine behind the pilot driving a four-bladed pusher propeller rotating between the booms.Francillon, p. 491. The booms were to extend aft from the leading edge of the wing and were mounted below the central nacelle. The aircraft was to have had tricycle landing gear and an armament of one 30-mm and two 20-mm cannon. Desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Mitsubishi Aircraft
The is a group of autonomous Japanese multinational companies in a variety of industries. Founded by Yatarō Iwasaki in 1870, the Mitsubishi Group historically descended from the Mitsubishi zaibatsu, a unified company which existed from 1870 to 1946. The company was disbanded during the occupation of Japan following World War II. The former constituents of the company continue to share the Mitsubishi brand and trademark. Although the group of companies participate in limited business cooperation, most famously through monthly "Friday Conference" executive meetings, they are formally independent and are not under common control. The four main companies in the group are MUFG Bank (the largest bank in Japan), Mitsubishi Corporation (a general trading company), Mitsubishi Electric and Mitsubishi Heavy Industries (both diversified manufacturing companies). History The Mitsubishi company was established as a shipping firm by Iwasaki Yatarō (1834–1885) in 1870 under the name . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940s Japanese Fighter Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Twin-boom Aircraft
A twin-boom aircraft is characterised by two longitudinal booms (extended nacelle-like bodies). The booms may contain ancillary items such as fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the tail surfaces, although on some types such as the Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from twin-fuselage designs in that it retains a central fuselage. Design The twin-boom configuration is distinct from the twin fuselage type in having a separate, short fuselage housing the pilot and payload. It has been adopted to resolve various design problems with the conventional empennage for aircraft in different roles. Engine mounting For a single engine with a propeller in the pusher configuration or a jet engine, a conventional tail requires the propeller or exhaust to be moved far aft, requiring either a very long driveshaft or jet pipe and thus reducing propulsive efficien ...

Vultee XP-54
The Vultee XP-54 ''Swoose Goose'' was a prototype fighter built by the Vultee Aircraft Company for the United States Army Air Forces (USAAF). Design and development Vultee submitted a proposal in response to a U.S. Army Air Corps request for an unusual configuration. The Vultee design won the competition, beating the Curtiss XP-55 Ascender and the Northrop XP-56 Black Bullet. Vultee designated it Model 84, a descendant of their earlier Model 78. After completing preliminary engineering and wind tunnel tests, a contract for a prototype was awarded on 8 January 1941. A second prototype was ordered on 17 March 1942. Although it appeared to be a radical design, performance was lackluster, and the project was canceled. The XP-54 was designed with a pusher engine in the aft part of the fuselage. The tail was mounted rearward between two mid-wing booms, with the twelve-foot propeller between them. The design included a "ducted wing section" developed by the NACA to potentially enab ...

SNCASO SO
SNCASO (abbreviated from ''Société nationale des constructions aéronautiques du Sud-Ouest'', or commonly, ''Sud-Ouest'') was a French aircraft manufacturer. Created during 1936 as one of seven nationalised aeronautical manufacturing companies, SNCASO became a key French aircraft manufacturer following the end of the Second World War. It produced numerous innovation aircraft; amongst the company's more notable projects was the first French jet aircraft, the Sud-Ouest Triton, and the first indigenously-developed French helicopter, the Sud-Ouest Djinn. On 1 March 1957, SNCASO merged with another French nationalised aviation company, SNCASE, (''Société nationale des constructions aéronautiques du Sud-Est''), to form Sud Aviation. History Following the resolution of the 1936 general strike of French heavy industry, the government of Léon Blum introduced an act to nationalize the French war industry. The act provided for the creation of seven nationalised aeronautical manufa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mansyū Ki-98
The Mansyū Ki-98, (also written as Manshū Ki-98), was a Japanese ground-attack aircraft proposed by Mansyū (''Manshūkoku Hikōki K.K.'' - Manchuria Airplane Manufacturing Company Ltd.) during World War II for use by the Imperial Japanese Army Air Force. The still unassembled components of the first prototype were deliberately destroyed before Japan surrendered. Design and development By late 1942, the Imperial Japanese Army Air Force issued requirements for new combat aircraft, including a ground attack aircraft. Kawasaki proposed the Kawasaki Ki-102 and Mansyū the Ki-98. The Ki-98 was to have been a single-seat, twin-boom, low-wing monoplane with a central nacelle housing both the cockpit and a turbosupercharged 1,643-kilowatt (2,200-hp) Mitsubishi Ha-211 Ru radial engine behind the pilot driving a four-bladed pusher propeller rotating between the booms.Francillon, p. 486.

Type 99 Cannon
The Type 99 Mark 1 machine gun and Type 99 Mark 2 machine gun were Japanese versions of the Oerlikon FF and Oerlikon FFL autocannons respectively. They were adopted by the Imperial Japanese Navy (IJN) in 1939 and served as their standard aircraft autocannon during World War II. Adoption In 1935, officers in the Imperial Japanese Navy began to investigate 20 mm automatic cannon as armament for future fighter aircraft.Robert C. Mikesh, ''Zero'', Motorbooks USA, 1994. Their attention was drawn to the family of aircraft autocannon manufactured by Oerlikon, the FF, FFL and FFS. These all shared the same operating principle, the advanced primer ignition blowback mechanism pioneered by the Becker cannon, but fired different ammunition: 20×72RB, 20×101RB, and 20×110RB, respectively. Following the import and evaluation of sample guns, the Imperial Japanese Navy decided in 1937 to adopt these weapons. To produce the Oerlikon guns, a group of retired Navy admirals created a new ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
