Vickers Warwick
The Vickers Warwick was a British twin-engined bomber aircraft developed and operated during the Second World War that was primarily used in other roles. In line with the naming convention followed by other RAF heavy bombers of the era, it was named after a British city or town, in this case Warwick. The Warwick was the largest British twin-engined aircraft to see use during the Second World War. The Warwick was designed and manufactured by Vickers-Armstrongs during the late 1930s. It was intended to serve as a larger counterpart to the Vickers Wellington bomber. The two aircraft share similar construction and design principles but development of the Warwick was delayed by a lack of suitable engines. Its first flight was on 13 August 1939 but delays to its intended powerplant and by the time adequate engines were available, it was obsolete.Barfield 1972, p. 145. The Warwick entered production during 1942 and squadron service with the Royal Air Force (RAF). Barely a dozen airc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th century, these hoods were known as turrets. Modern warships have gun-m ... [...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 ...

Bristol Centaurus
The Centaurus was the final development of the Bristol Engine Company's series of sleeve valve radial aircraft engines. The Centaurus is an 18-cylinder, two-row design that eventually delivered over . The engine was introduced into service late in the Second World War and was one of the most powerful aircraft piston engines to see service. Design and development Like other Bristol sleeve valve engines, the Centaurus was based on the design knowledge acquired from an earlier design, in this case the Bristol Perseus cylinder. The Centaurus used 18 Perseus cylinders. The same cylinder was in use in the contemporary 14-cylinder Hercules, which was being brought into production when the design of the Centaurus started. The Centaurus had a cylinder swept volume of , nearly as much as the American Wright R-3350 ''Duplex-Cyclone'' large radial, making the Centaurus one of the largest aircraft piston engines to enter production, while that of the Hercules was .

Hawker Typhoon
The Hawker Typhoon was a British single-seat fighter-bomber, produced by Hawker Aircraft. It was intended to be a medium-high altitude interceptor aircraft, interceptor, as a replacement for the Hawker Hurricane, but several design problems were encountered and it never completely satisfied this requirement.Thomas and Shores 1988, p. 16. The Typhoon was originally designed to mount twelve .303 British, .303 inch (7.7 mm) M1919 Browning machine gun, Browning machine guns and be powered by the latest engines. Its service introduction in mid-1941 was plagued with problems and for several months the aircraft faced a doubtful future. When the ''Luftwaffe'' brought the new Focke-Wulf Fw 190 into service in 1941, the Typhoon was the only RAF fighter capable of catching it at low altitudes; as a result it secured a new role as a low-altitude interceptor. The Typhoon became established in roles such as night-time intruder and long-range fighter. From late 1942 the Typhoon was equipped ...

Napier Sabre
The Napier Sabre is a British H engine, H-24-cylinder, coolant, liquid-cooled, sleeve valve, piston aircraft engine, aero engine, designed by Frank Halford, Major Frank Halford and built by D. Napier & Son during World War II. The engine evolved to become one of the most powerful Inline engine (aviation), inline piston aircraft engines in the world, developing from in its earlier versions to in late-model prototypes. The first operational aircraft to be powered by the Sabre were the Hawker Typhoon and Hawker Tempest; the first aircraft powered by the Sabre was the Napier-Heston Racer, which was designed to capture the world speed record. Other aircraft using the Sabre were early prototype and production variants of the Blackburn Firebrand, the Martin-Baker MB 3 prototype and a Hawker Sea Fury, Hawker Fury prototype. The rapid introduction of jet engines after the war led to the quick demise of the Sabre, as there was less need for high power military piston aero engines and b ...

Avro Manchester
The Avro 679 Manchester was a British twin-engine heavy bomber developed and manufactured by the Avro aircraft company in the United Kingdom. While not being built in great numbers, it was the forerunner of the more famed and more successful four-engined Avro Lancaster, which was one of the most capable strategic bombers of the Second World War. Avro designed the Manchester in conformance with the requirements laid out by the British Air Ministry Specification P.13/36, which sought a capable medium bomber with which to equip the Royal Air Force (RAF) and to replace its twin-engine bombers, such as the Armstrong Whitworth Whitley, Handley Page Hampden and Vickers Wellington. Performing its maiden flight on 25 July 1939, the Manchester entered squadron service in November 1940, just over twelve months after the outbreak of the war. Operated by the RAF and the Royal Canadian Air Force (RCAF), the Manchester came to be regarded as a failure, primarily as a result of its ...

X Engine
An X engine is a piston engine with four banks of cylinders around a common crankshaft, such that the cylinders form an "X" shape when viewed front-on. The advantage of an X engine is that it is shorter than a V engine of the same number of cylinders, however the drawbacks are greater weight and complexity as compared to a radial engine. Therefore, the configuration has been rarely used. Several of the X engine designs were based on combining two V engines. Examples Four types of X engines are known to have reached production. In 1939–1942 Rolls-Royce Vulture, a X-24 aircraft engine which was built using two Rolls-Royce Peregrine V12 engines. The Rolls-Royce Vulture was briefly used in the Avro Manchester heavy bomber, before engine failures caused it to be replaced by the Avro Lancaster (powered by the Rolls-Royce Merlin V12 engine). General Motors also produced X engines for US naval ships during the Second World War. The 16-184 engine was installed in several hundred ...

Rolls-Royce Vulture
The Rolls-Royce Vulture was a British Aircraft engine, aero engine developed shortly before World War II that was designed and built by Rolls-Royce Limited. The Vulture used the unusual "X-24 engine, X-24" configuration, whereby four cylinder blocks derived from the Rolls-Royce Peregrine were joined by a common crankshaft supported by a single crankcase. The engine was originally designed to produce around but problems with the Vulture design meant that the engines were derated to around 1,450 to 1,550 hp in service by limiting the maximum Revolutions per minute, rpm. Although several new aircraft designs had been planned to use the Vulture, work on the engine's design ended in 1941 as Rolls-Royce concentrated on their more successful Rolls-Royce Merlin, Merlin design. Another 24-cylinder engine, the Napier Sabre, proved more successful after a lengthy development period.

World Disarmament Conference
The Conference for the Reduction and Limitation of Armaments, generally known as the Geneva Conference or World Disarmament Conference, was an international conference of states held in Geneva, Switzerland, between February 1932 and November 1934 to accomplish disarmament in accordance with the Covenant of the League of Nations. It was attended by 61 states, most of which were members of the League of Nations, but the USSR and the United States also attended. The conference was a response to the militarisation of global powers during and after the First World War. Aimed towards a global reduction in arms, the conference was organised and campaigned for by the League of Nations with the main objective to avoid another world war. The conference symbolised global co-operation to a combined goal of limiting arms, but it is generally perceived as a failure because of the onset of the Second World War five years later and the withdrawal of Nazi Germany from both the conference and the ...

Armstrong Whitworth Whitley
The Armstrong Whitworth A.W.38 Whitley was a British medium/heavy bomber aircraft of the 1930s. It was one of three twin-engined, front line medium bomber types that were in service with the Royal Air Force (RAF) at the outbreak of the World War II, Second World War. Alongside the Vickers Wellington and the Handley Page Hampden, the Whitley was developed during the mid-1930s according to Air Ministry List Of Air Ministry Specifications, Specification B.3/34, which it was subsequently selected to meet. In 1937, the Whitley formally entered into RAF squadron service; it was the first of the three medium bombers to be introduced. Following the outbreak of war in September 1939, the Whitley participated in the first RAF bombing raid upon German territory and remained an integral part of the early British bomber offensive. In 1942 it was superseded as a bomber by the larger four-engined "Heavy bomber#World War II 2, heavies" such as the Avro Lancaster. Its front-line service include ...
