Gloster Gladiator II
The Gloster Gladiator is a British biplane fighter. It was used by the Royal Air Force (RAF) and the Fleet Air Arm (FAA) (as the Sea Gladiator variant) and was exported to a number of other air forces during the late 1930s. Developed privately as the Gloster SS.37, it was the RAF's last biplane fighter aircraft, and was rendered obsolete by newer monoplane designs even as it was being introduced. Though often pitted against more formidable foes during the early days of the Second World War, it acquitted itself reasonably well in combat. The Gladiator saw action in almost all theatres during the Second World War, with a large number of air forces, some of them on the Axis side. The RAF used it in France, Norway, Greece, the defence of Malta, the Middle East, and the brief Anglo-Iraqi War (during which the Royal Iraqi Air Force was similarly equipped). Other countries deploying the Gladiator included China against Japan, beginning in 1938; Finland (along with Swedish volunte ...

Greco-Italian War
The Greco-Italian War (Greek language, Greek: Ελληνοϊταλικός Πόλεμος, ''Ellinoïtalikós Pólemos''), also called the Italo-Greek War, Italian Campaign in Greece, and the War of '40 in Greece, took place between the kingdoms of Fascist Italy (1922–1943), Italy and Kingdom of Greece, Greece from 28 October 1940 to 23 April 1941. This local war began the Balkans Campaign (World War II), Balkans Campaign of World War II between the Axis powers and the Allies of World War II, Allies and eventually turned into the Battle of Greece with Commonwealth of Nations, British and Nazi Germany, German involvement. On 10 June 1940, Italy declared war on France and the United Kingdom. By September 1940, the Italians had Italian invasion of France, invaded France, Italian conquest of British Somaliland, British Somaliland and Italian invasion of Egypt, Egypt. This was followed by a hostile press campaign in Italy against Greece, accused of being a British ally. A number of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breech-loading Weapon
A breechloader is a firearm in which the user loads the ammunition (cartridge or shell) via the rear (breech) end of its barrel, as opposed to a muzzleloader, which loads ammunition via the front ( muzzle). Modern firearms are generally breech-loading – except for replicas of vintage weapons. Early firearms before the mid-19th century were almost entirely muzzle-loading. Mortars and the Russian GP-25 grenade launcher are the only muzzleloaders remaining in frequent modern usage. However, referring to a weapon specifically as breech loading is mostly limited to single-shot or otherwise non-repeating firearms, such as double-barreled shotguns. Breech-loading provides the advantage of reduced reloading time, because it is far quicker to load the projectile and propellant into the chamber of a gun/cannon than to reach all the way over to the front end to load ammunition and then push them back down a long tube – especially when the projectile fits tightly and the ...

Radiator (engine Cooling)
Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plant or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called ''engine coolant'' through the engine block, and cylinder head where it is heated, then through a radiator where it loses heat to the atmosphere, and then returned to the engine. Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant to circulate, and also for an axial fan to force air through the radiator. Automobiles and motorcycles In automobiles and motorcycles with a liquid-cooled internal combustion engine, a radiator is connected to channels running through the engine and cylinder head, through which a liquid (coolant) is pumped. This liquid may be water (in climates where water is unlik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce Goshawk
The Rolls-Royce Goshawk was a development of the Rolls-Royce Kestrel that used evaporative or steam cooling. In line with Rolls-Royce convention of naming piston engines after birds of prey, it was named after the goshawk. The engine first ran in 1933 and provided 660 horsepower (490 kW). Only a few engines were built as the aircraft designs intended to use it were not adopted by the Royal Air Force. The Goshawk was used to power the Short Knuckleduster, the Supermarine Type 224 (a predecessor to the Supermarine Spitfire) and other prototype aircraft. Design and development The Goshawk was developed from the Kestrel IV prototype engine, to use evaporative (also known as "steam") cooling. Rather than keep the cooling liquid below its boiling point in the cooling system, the coolant was allowed to boil; the phase change from liquid to vapour takes more heat from the engine, so less weight of coolant is needed. However, the radiator had to be bulkier to accommodate coola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Air Ministry Specifications
This is a partial list of the British Air Ministry (AM) specifications for aircraft. A specification stemmed from an Operational Requirement, abbreviated "OR", describing what the aircraft would be used for. This in turn led to the specification itself, e.g. a two-engined fighter with four machine guns. So for example, OR.40 for a heavy bomber led to Specification B.12/36. Aircraft manufacturers would be invited to present design proposals to the ministry, following which prototypes of one or more of the proposals might be ordered for evaluation. On very rare occasions, a manufacturer would design and build an aircraft using their own money as a "private venture" (PV). This would then be offered to the ministry for evaluation. If the aircraft generated interest in the ministry or RAF due to performance or some other combination of features then the ministry might well issue a specification based on the private venture aircraft. The system of producing aircraft to a specification ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Ministry
The Air Ministry was a department of the Government of the United Kingdom with the responsibility of managing the affairs of the Royal Air Force, that existed from 1918 to 1964. It was under the political authority of the Secretary of State for Air. Organisations before the Air Ministry The Air Committee On 13 April 1912, less than two weeks after the creation of the Royal Flying Corps (which initially consisted of both a naval and a military wing), an Air Committee was established to act as an intermediary between the Admiralty and the War Office in matters relating to aviation. The new Air Committee was composed of representatives of the two war ministries, and although it could make recommendations, it lacked executive authority. The recommendations of the Air Committee had to be ratified by the Admiralty Board and the Imperial General Staff and, in consequence, the Committee was not particularly effective. The increasing separation of army and naval aviation from 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pat Pattle
Marmaduke Thomas St John Pattle, (3 July 1914 – 20 April 1941), usually known as Pat Pattle, was a South African-born English Second World War fighter pilot and flying ace (an aviator credited with the destruction of five or more enemy aircraft in aerial combat) of the Royal Air Force (RAF). Pattle applied to join the South African Air Force at 18, but was rejected. He travelled to the United Kingdom and joined the RAF in 1936 on a Short Service Commission. Pattle was a pilot by 1937 and was posted to No. 80 Squadron based in Egypt upon the outbreak of war in September 1939. In June 1940, Italy entered the war on the side of the Axis Powers and he began combat operations against the ''Regia Aeronautica'' (Italian Air Force), gaining his first successes during the Italian invasion of Egypt. After the Italian invasion, his squadron was sent to Greece in November 1940, where Pattle achieved most of his victories. Pattle claimed around 20 aircraft shot down and in Marc ...

Continuation War
The Continuation War, also known as the Second Soviet-Finnish War, was a conflict fought by Finland and Nazi Germany against the Soviet Union from 1941 to 1944, as part of World War II.; sv, fortsättningskriget; german: Fortsetzungskrieg. According to Finnish historian Olli Vehviläinen, the term 'Continuation War' was created at the start of the conflict by the Finnish government, to justify the invasion to the population as a continuation of the defensive Winter War and separate from the German war effort. He titled the chapter addressing the issue in his book as "Finland's War of Retaliation". Vehviläinen asserted that the reality of that claim changed when the Finnish forces crossed the 1939 frontier and started annexation operations. The US Library of Congress catalogue also lists the variants War of Retribution and War of Continuation (see authority control)., group="Note" In Soviet historiography, the war was called the Finnish Front of the Great Patriotic War..

Flying Regiment 19, Finnish Air Force
The Flight Regiment 19 ( sv, Flygflottilj 19, fi, Lentorykmentti 19 or ), also known as the Swedish Voluntary Air Force or F 19 was a Finnish Air Force unit, manned by Swedish volunteers, which operated from Kemi in northern Finland for the last 62 days of the Winter War. The aircraft also came from the Swedish Air Force inventory. Its designation number was taken from the Swedish Air Force which had 18 flying regiments at the time. The designation F 19 has not been used in Sweden. When new regiments were formed they were named F 20, F 21 and F 22. The unit made a significant contribution to the defense of Finnish Lapland, from January 7, 1940, with 12 Gloster Gladiator II fighters, five Hawker Hart bombers, and eight other planes. In total, the unit destroyed twelve Soviet aircraft (eight in the air, four on the ground), and lost a total of six planes; two to enemy action and four to accidents. Three of its pilots were killed and two more were captured by Soviet forces. The cap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
