Vickers Type 432
The Vickers Type 432 was a British high-altitude fighter aircraft developed by the Vickers group during the Second World War. Intended to enable the Royal Air Force to engage the enemy's high-altitude bomber aircraft, it was to be armed with six cannons. Design and development The origins of the Type 432 lay with a requirements set out in 1939 for twin-engined fighters with 20 or possibly 40 mm cannon. Vickers had set out a proposal for a Griffon-engined aircraft, equipped with a 40 mm cannon in a flexible mounting. This was subsequently encouraged by the Air Ministry. Further development was carried out for a design that could also meet F.6/39 for a fixed gun fighter with 20mm cannon. Specification F.22/39 was drawn up to cover the 40mm project as the Vickers 414 to meet Operational Requirement (OR) 76. This was subsequently revised with aircraft redesigns to become specifications F.16/40 and then F.7/41 for OR. 108. In appearance it resembled a larger version of ...

Barnes Wallis
Sir Barnes Neville Wallis (26 September 1887 – 30 October 1979) was an English engineer and inventor. He is best known for inventing the bouncing bomb used by the Royal Air Force in Operation Chastise (the "Dambusters" raid) to attack the dams of the Ruhr Valley during World War II. The raid was the subject of the 1955 film '' The Dam Busters'', in which Wallis was played by Michael Redgrave. Among his other inventions were his version of the geodetic airframe and the earthquake bomb. Early life and education Barnes Wallis was born in Ripley, Derbyshire, to Charles William George Robinson Wallis (1859–1945) and his wife Edith Eyre Wallis née Ashby (1859–1911). He was educated at Christ's Hospital in Horsham and Haberdashers' Aske's Hatcham Boys' Grammar School in southeast London, leaving school at seventeen to start work in January 1905 at Thames Engineering Works at Blackheath, southeast London. He subsequently changed his apprenticeship to J. Samuel White's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nakajima J5N
The Nakajima J5N was an abandoned Japanese prototype fighter aircraft of the World War II era. J5N was developed as twin-engine interceptor for countering attacks by Boeing B-29 Superfortress. Design and development During the spring of 1943, the JNAF issued an 18-Shi specification for a single-seat twin-engine interceptor capable of reaching a top speed of 666 km/h (414 mph) at 6,000 m (19,690 ft). Nakajima submitted a proposal based on the earlier J1N1 ''Gekko'' three-seat night fighter, although this new aircraft – designated J5N1 – was slightly smaller. The layout of the J5N was similar to the J1N: a low set wing on which were mounted the two powerplants, 1,484 kW (1,990 hp) Nakajima Homare 21 18-cylinder air-cooled radial engines, with a long fuselage ending in a conventional tail arrangement. For maximum utilization of the power from the twin engines, large four-blade propellers were fitted which also featured large spinners (as fitt ...

Messerschmitt Me 310
The Messerschmitt Me 310 was a prototype German heavy fighter of World War II. It was a project to save the aerodynamically troubled Me 210. Design and development The armament was to be the same as the Me 210 A-1: two 20 mm MG 151/20 cannon, two 7.92 mm (.312 in) MG 17 machine guns, and two remotely controlled, rearward-firing 13 mm (.51 in) MG 131 machine guns. A single aircraft was built by converting Me 210 V13 (code GI+SQ). It had a pressurised cockpit and was powered by two 1,380 kW (1,850 hp) Daimler-Benz DB 603A inline engines. The Me 310 first flew on 11 September 1943, but the project was cancelled later the same year, as it showed hardly any aerodynamic improvement over the Me 210. A subsequent prototype, the Me 410 The Messerschmitt Me 410 ''Hornisse'' (Hornet) is a German heavy fighter and ''Schnellbomber'' used by the ''Luftwaffe'' during World War II. Though an incremental improvement of the Me 210, it had a new wing pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed P-38
The Lockheed P-38 Lightning is an American single-seat, twin piston-engined fighter aircraft that was used during World War II. Developed for the United States Army Air Corps by the Lockheed Corporation, the P-38 incorporated a distinctive twin boom, twin-boom design with a central nacelle containing the cockpit and armament. Along with its use as a general fighter aircraft, fighter, the P-38 was used in various aerial combat roles, including as a highly effective fighter-bomber, a night fighter, and a Range (aircraft), long-range escort fighter when equipped with drop tanks. The P-38 was also used as a bomber-pathfinder, guiding streams of medium bomber, medium and heavy bombers, or even other P-38s equipped with bombs, to their targets."P-38 Lightning" National M ...

Kawasaki Ki-96
The Kawasaki Ki-96 was a Japanese single seat, twin-engine heavy fighter of World War II. It was intended to replace the Kawasaki Ki-45s of the Imperial Japanese Army Air Service. However, it was not adopted and only three prototypes were built. Design and development The success of the Kawasaki Ki-45 led Kawasaki to start development of an evolved version, on Kawasaki's own authority, in August 1942. Like the Ki-45, the proposed design was a two-seat, twin-engine fighter, but larger and using more powerful engines. In December 1942 the ''Koku Hombu'' ( Imperial Japanese Army Aviation Bureau) showed interest, but asked Kawasaki to complete the aircraft as single-seat fighters. The first prototype, which was converted while being produced and which retained the larger cockpit canopy Canopy may refer to: Plants * Canopy (biology), aboveground portion of plant community or crop (including forests) * Canopy (grape), aboveground portion of grapes Religion and ceremonies * Balda ...

Hughes D-2
The Hughes D-2 was an American fighter and bomber project begun by Howard Hughes as a private venture. It never proceeded past the flight testing phase but was the predecessor of the Hughes XF-11. The sole D-2 was completed in 1942–1943. Design and development In 1937, Howard Hughes began the design of an advanced twin-engine, twin-boom aircraft. The D-2's early gestation is historically obscure because Hughes Aircraft and its corporate successors have never released archives regarding the D-2; however, Howard Hughes had recently set a global circumnavigation speed record in a Lockheed 14. Aircraft historian René Francillon speculates that Hughes probably initiated the project for another circumnavigation record attempt, but the outbreak of World War II closed much of the world's airspace and made it difficult to buy aircraft parts without government approval, so he decided to sell the aircraft to the U.S. military instead. The first documentary evidence of the project is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grumman XP-50
The Grumman XP-50 was a land-based development of the shipboard XF5F-1 Skyrocket fighter, entered into a United States Army Air Corps (USAAC) contest for a twin-engine heavy interceptor aircraft. The USAAC placed an order for a prototype on 25 November 1939, designating it XP-50, but it lost the competition to the Lockheed XP-49. Design and development First assigned Design 34, later G-41 by the builder, Grumman, the design was entered into competition alongside proposals from Bell, Brewster, Curtiss, Lockheed, and Vought.Baugher, Joe"Grumman XP-50."''USAAC/USAAF/USAF Fighter Aircraft'', 2 August 1999. Retrieved: 2 April 2010. The XP-50 design was similar to that of the XF5F-1 with modifications to the fuselage nose to house the nose-wheel of the tricycle landing gear and provisions for self-sealing fuel tanks and pilot armor. The planned armament was two 20 mm (.79 in) cannon and two .50 in (12.7 mm) machine guns.Dorr and Donald 1990, p. 119. Testing Durin ...

Focke-Wulf Fw 187
The Focke-Wulf Fw 187 ''Falke'' ("Falcon") was a Nazi Germany, German aircraft developed in the late 1930s. It was conceived by Kurt Tank as a twin-engine, high-performance Fighter aircraft, fighter, but the ''Luftwaffe'' saw no role for the design, perceiving it as intermediate between the Messerschmitt Bf 109 and Messerschmitt Bf 110, Bf 110. Later prototypes were adapted to two-seats to compete with the Bf 110 in the ''Zerstörer'' (heavy fighter) role, but only nine aircraft were built in total. Design and development In the early to mid-1930s, developments in airframe design outpaced available aircraft engine power. Consequently, some designs with two engines outperformed aircraft with just one engine. In European air races, the Dornier Do 17 - a military design concealed under the guise of civilian use - proved faster than single-engined fighters. Although the period of twin-engine superiority was brief, it sparked the idea in Nazi Germany of the "''schnellbomber''" (fast bom ...

Arado Ar 240
The Arado Ar 240 was a German twin-engine, multi-role heavy fighter aircraft, developed for the ''Luftwaffe'' during World War II by Arado Flugzeugwerke. Its first flight was in 1940, but problems with the design hampered development, and it remained only marginally stable throughout the prototype phase. The project was eventually cancelled, with the existing airframes used for a variety of test purposes. Design and development The Ar 240 came about as the response to a 1938 request for a much more capable second-generation heavy fighter to replace the Messerschmitt Bf 110, which was becoming outdated. Both Arado and Messerschmitt responded. Messerschmitt's response, the Me 210, was a totally new design, but thanks to Messerschmitt's experience with the ''Zerstörer'' ("Destroyer") concept, it would be able to enter service quickly. Arado's design was considerably more ambitious for the smaller firm, a dream project of Arado's chief designer, Walter Blume, since the mid-1930s. ...

Hispano-Suiza HS
Hispano-Suiza () is a Spanish automotive–engineering company. It was founded in 1904 by Marc Birkigt and Damian Mateu as an automobile manufacturer and eventually had several factories in Spain and France that produced luxury cars, aircraft engines, trucks and weapons. In 1923, its French luxury car arm became a semi-autonomous partnership with the Spanish parent company. In 1946, the Spanish parent company sold all of its Spanish automotive assets to Enasa, a Spanish state-owned vehicle manufacturer, and the French arm continued as an independent aviation engine and components manufacturer under the Hispano-Suiza name. In 1968, Hispano-Suiza was taken over by the aerospace company Snecma, which is now part of the French Safran, Safran Group. An attempt to relaunch the marque was made by the company Hispano Suiza Cars associated with the Peralada Group (owned by the Suqué Mateu family) in 2019 with a fully-electric car.

V12 Engine
A V12 engine is a twelve-cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and ...
