Rikugun Ki-93
The Rikugun Ki-93 was a prototype Japanese twin-engined fighter aircraft of the Second World War. Designed by the Army Aerotechnical Research Institute, to be a heavy fighter armed with large calibre cannon to serve in the anti-shipping or bomber destroyer roles, only one example of the Ki-93 was completed; this was damaged on its maiden flight, and destroyed by American bombing before it could be flown again. Development and design In mid 1941, a team was set up at the Japanese Army Aerotechnical Research Institute (or ''Rikugun Kokugijutsu Kenkyujo'', known by the abbreviation Giken) to study advanced military aircraft. The team drew up preliminary designs for a twin-engined heavy fighter for the Imperial Japanese Army Air Service, to be powered by two Mitsubishi Ha-211 radial engines and estimated to reach a speed of 680 km/h (422 mph). In July 1942, the design, along with some of the team from Giken, was passed to the First Army Air Arsenal (''Dai-Ichi Rikugun K ...

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.

Junkers Ju 88
The Junkers Ju 88 is a German World War II ''Luftwaffe'' twin-engined multirole combat aircraft. Junkers Aircraft and Motor Works (JFM) designed the plane in the mid-1930s as a so-called ''Schnellbomber'' ("fast bomber") that would be too fast for fighters of its era to intercept. It suffered from technical problems during its development and early operational periods but became one of the most versatile combat aircraft of the war. Like a number of other ''Luftwaffe'' bombers, it served as a bomber, dive bomber, night fighter, torpedo bomber, reconnaissance aircraft, heavy fighter and at the end of the war, as a flying bomb. Despite a protracted development, it became one of the ''Luftwaffe''s most important aircraft. The assembly line ran constantly from 1936 to 1945 and more than 15,000 Ju 88s were built in dozens of variants, more than any other twin-engine German aircraft of the period. Throughout production the basic structure of the aircraft remained unchanged.Angelucci a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kawasaki Ki-102
The Kawasaki Ki-102 (Army Type 4 assault aircraft) was a Japanese warplane of World War II. It was a twin-engine, two-seat, long-range heavy fighter developed to replace the Ki-45 ''Toryu''. Three versions were planned: the Ki-102a day fighter, Ki-102b ground-attack and Ki-102c night fighter. This aircraft's Allied reporting name was "Randy". Design and history The Ki-102 entered service in 1944, but saw limited action. The main type (102b) was kept in reserve to protect Japan, although it did see some limited duty in the Okinawa campaign. It was kept out of front line service because it was hoped that it would be the carrier of the Igo-1-B air-to-ground guided missile when the Allied invasion of Japan occurred. Variants ; Ki-102 : prototypes, three built ; Ki-102a (Type Kō) :Externally similar to the 102b, but with turbosuperchargers that enabled the engine to maintain its rating at higher altitudes. The 57 mm (2.24 in) cannon was swapped in favor of a 37 mm (1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henschel Hs 129
The Henschel Hs 129 was a World War II ground-attack aircraft fielded by the German ''Luftwaffe''. The aircraft saw combat in Tunisia and on the Eastern Front. A key requirement of the original specification was that the aircraft be powered by engines that were not in demand for other designs. Prototypes with low-power German Argus As 410 engines of failed acceptance test, a more powerful replacement was found with the French Gnome-Rhône 14M engine of . The design was relatively effective when it was first introduced, and saw service on the Eastern Front in a variety of front-line roles. As the war continued and anti-tank support became the main goal, the aircraft was continually up-gunned, eventually mounting a 75 mm anti-tank gun. Only a small number of these B-3 models were produced, late in the war. Design and development By the mid-1930s, the German military, as well as its counterparts in other countries, had come to see the main role of ground-attack aircraft as ...

De Havilland Mosquito
The de Havilland DH.98 Mosquito is a British twin-engined, shoulder-winged, multirole combat aircraft, introduced during the Second World War. Unusual in that its frame was constructed mostly of wood, it was nicknamed the "Wooden Wonder", or "Mossie". Lord Beaverbrook, Minister of Aircraft Production, nicknamed it "Freeman's Folly", alluding to Air Chief Marshal Sir Wilfrid Freeman, who defended Geoffrey de Havilland and his design concept against orders to scrap the project. In 1941, it was one of the fastest operational aircraft in the world.Bowman 2005, p. 21. Originally conceived as an unarmed fast bomber, the Mosquito's use evolved during the war into many roles, including low- to medium-altitude daytime tactical bomber, high-altitude night bomber, pathfinder, day or night fighter, fighter-bomber, intruder, maritime strike, and photo-reconnaissance aircraft. It was also used by the British Overseas Airways Corporation as a fast transport to carry small, high-value c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Brigand
The Bristol Brigand was a British anti-shipping/ground attack/dive bomber aircraft, developed by the Bristol Aeroplane Company as a replacement for the Beaufighter. A total of 147 were built and were used by the Royal Air Force in Malaya during the Malayan Emergency and Kenya until replaced by the de Havilland Hornet in Malaya and the English Electric Canberra jet bomber elsewhere. Design and development The Bristol Type 164 was the outcome of the 1942 Air Ministry specification H.7/42 calling for a faster development of the Beaufighter for long-range torpedo work and anti-shipping strikes. The Bristol design team under Leslie Frise, used the wings, tail and undercarriage of the Buckingham with a new fuselage of oval cross-section. The pilot, navigator/bomb aimer and radio-operator/gunner were grouped in the forward cockpit. In spite of the official change in its role to a bomber, the first eleven Brigands off the production line were completed as torpedo bombers. These earl ...

Ho-103 Machine Gun
The Type 1 machine gun (Type (designation), 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. 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 sourced from various Italian Breda-SAFAT machine gun, Breda-SAFAT 12.7 mm rounds. Japanese-designed and produced rounds would eventually mostly replace these imported rounds. The Ho-103 achieved a slightly higher rate of fire 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 machine gun, MG 131's ‘short’ 64 mm cartridge, and the ‘long’ 99 mm cartridge of the M2 Browning. A high rate of fire was very des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ho-5 Cannon
The Ho-5 (Army Type 2) was a Japanese aircraft autocannon used during World War II. Developed from the Ho-103 machine gun, it was a version of the American Model 1921 Browning aircraft machine gun. It replaced the Ho-1 and Ho-3 (Army Type 97) in general service. The Ho-5 was belt-fed using typical Browning-style steel disintegrating links. The cartridge used was a shortened version of the Allied 20 x 110mm Hispano-Suiza HS.404. The Ho-5 was used mostly as wing mounts in late-war fighters, but saw limited use as cowl mounted in fighters and as flexible mounted (retrofit) in bombers.

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 added i ...
