Tachikawa Ki-92
The Tachikawa Ki-92 was an experimental Japanese heavy transport aircraft of World War II. It was a low-wing monoplane with a pressurized fuselage, twin piston engines and a tailwheel undercarriage. Development In March 1942 the Imperial Japanese Army Air Service chose Tachikawa Aircraft Company to design and build a new heavy twin engine transport aircraft with a focus on increased range, power and speed to carry light tanks, field artillery and troops. Shinjiro Shinagawa was in charge of the development and began work in March 1943 and had the first prototype completed by September 1944. Like Tachikawa's Ki-77 the aircraft featured a laminar flow airfoil. The Ki-92 also had a sealed cabin with double glazed windows seating 34 troops in 4 rows (including two emergency seats) to reduce the need for oxygen, and forced draught cooling in low drag engine nacelles. Due to various repairs and modifications, the first flight did not occur until April 1945. The test flight recorded a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new type must be certified by a governing agency (such as the Federal Aviation Administration in the United States) before it can enter ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple wings. 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 (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

Curtiss C-46 Commando
The Curtiss C-46 Commando is a low-wing, twin-engine aircraft derived from the Curtiss CW-20 pressurized high-altitude airliner design. Early press reports used the name "Condor III" but the Commando name was in use by early 1942 in company publicity. It was used primarily as a cargo aircraft during World War II, with fold-down seating for military transport and some use in delivering paratroops. Mainly deployed by the United States Army Air Forces, it also served the U.S. Navy/ Marine Corps, which called it R5C. The C-46 filled similar roles as its Douglas-built counterpart, the C-47 Skytrain, with some 3,200 C-46s produced to approximately 10,200 C-47s. After World War II, a few surplus C-46 aircraft were briefly used in their original role as passenger airliners but the glut of surplus C-47s dominated the marketplace and the C-46 was soon relegated to cargo duty. The type continued in U.S. Air Force service in a secondary role until 1968. The C-46 continues in operation as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ho-103 Machine Gun
The Type 1 machine gun ( signifying its year of adoption, 1941) was a Japanese aircraft-mounted heavy machine gun widely used during World War II. It was also known as the Ho-103 in general use. The weapon itself was largely based on the American .50-caliber (12.7 mm) M2 Browning heavy machine gun, while the design of its ammunition was initially based on various Italian Breda-SAFAT 12.7 mm rounds. Japanese-designed and produced rounds eventually largely replaced these imported rounds. The Ho-103 achieved a slightly higher rate of fire (RoF) than the contemporary aircraft-mounted M2 Browning machine gun (AN/M2) by using the smaller, lower velocity semi-rimmed Breda-SAFAT 12.7 mm cartridge. The round was intermediate in length (88 mm) between the WWII German 13 mm calibre MG 131's ‘short’ 64 mm cartridge, and the ‘long’ 99 mm cartridge of the M2 Browning. A high RoF was very desirable among aircraft weaponry; with the ever-increasing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, 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 ar ...

Mitsubishi Ha104
The is a group of autonomous Japanese multinational companies in a variety of industries. Founded by Yatarō Iwasaki in 1870, the Mitsubishi Group traces its origins to the Mitsubishi zaibatsu, a unified company that existed from 1870 to 1946. The company, along with other major zaibatsu, was disbanded during the occupation of Japan following World War II by the order of the Allies. Despite the dissolution, the former constituent companies continue to share the Mitsubishi brand and trademark. While the group of companies engages in limited business cooperation, most notably through monthly "Friday Conference" executive meetings, they remain formally independent and are not under common control. The three main entities (''gosanke'') are Mitsubishi UFJ Financial Group (the largest bank in Japan), Mitsubishi Corporation (a general trading company), and Mitsubishi Heavy Industries (a diversified manufacturing company). A 2020 estimate concluded that all the Mitsubishi companies co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II Allied Names For Japanese Aircraft
The World War II Allied names for Japanese aircraft were reporting names, often described as codenames, given by Allied personnel to Imperial Japanese aircraft during the Pacific campaign of World War II. The names were used by Allied personnel to identify aircraft operated by the Japanese for reporting and descriptive purposes. Generally, Western men's names were given to fighter aircraft and single engine reconnaissance aircraft, women's names to bombers, twin engine reconnaissance aircraft and if the name started with "T", transports, bird names to gliders, and tree names to trainer aircraft. The use of the names, from their origin in mid-1942, became widespread among Allied forces from early 1943 until the end of the war in 1945. Many subsequent Western histories of the war have continued to use the names. History During the first year of the Pacific War beginning on 7 December 1941, Allied personnel often struggled to quickly, succinctly, and accurately identify Japanese ...

Technical Air Intelligence Unit
Technical Air Intelligence Units (TAIU) were joint Allied military intelligence units formed during World War II to recover Japanese aircraft to obtain data regarding their technical and tactical capabilities. The first such unit, known later as Technical Air Intelligence Unit– South West Pacific (TAIU–SWPA), was formed in November 1942 by the United States Navy (USN), United States Army Air Forces (USAAF) and Royal Australian Air Force (RAAF) at Eagle Farm Airbase, Brisbane, Australia, in November 1942. During 1943–44, three other TAIUs were formed in the other Allied theatres of the Pacific War.Harold Skaarup, 2006, ''RCAF War Prize Flights, German and Japanese Warbird Survivors'', Bloomington Indiana, iUniverse, pp33–4. * South East Asia: ATAIU–SEA; British Royal Air Force (RAF)/USAAF * Pacific Ocean Areas: TAIU–POA; USN * China: Republic of China Air Force A proposed joint U.S. Army-U.S. Navy research unit in the continental United S ...
