Hispano Aviación HA-1112
The Hispano Aviación HA-1109 and HA-1112 are licence-built versions of the Messerschmitt Bf 109G-2 developed in Spain during and after World War II. Design and development In 1942, the Spanish government arranged a manufacturing licence with Messerschmitt AG to build the Bf 109G-2, although the DB 605A engines, propellers, instruments and weapons were to be supplied from Germany. This proved impossible as Germany was incapable of meeting its own needs, let alone Spain's, and only 25 airframes (without their tails) and less than half the necessary drawings were actually delivered. Consequently, Hispano Aviación replaced the DB 605A engine with the 1,300 hp HS 89-12Z and the project was renamed Bf 109J by Messerschmitt. The HS 89-12Z engine performed a successful flight in a Bf 109E used as a flying testbed in Barcelona in 1944, and the first HA-1109-J1L made its maiden flight on 2 March 1945 in Seville, using a VDM propeller and lash-up engine mounting.Fitzsimons, ...

De Havilland Propellers
de Havilland Propellers was established in 1935, as a division of the de Havilland Aircraft company when that company acquired a licence from the Hamilton Standard company of America for the manufacture of variable-pitch propellers at a cost of about £20,000. Licence negotiations were completed in June 1934. de Havilland Propellers, Ltd., was incorporated on 27 April 1946, with the main headquarters at Hatfield as the centre of design, development, and flight-testing, and with the main production plant at Lostock in Lancashire. The factory had been built in only nine months as part of the government's emergency pre-war shadow-factory programme. Work on missiles began in the late 1940s, early 1950s at the Hatfield plant in facilities which had been used during the war for the development and testing of aircraft propellers. By the early sixties, the company became Hawker Siddeley Dynamics which in turn became ''British Aerospace Dynamics,'' later BAE Systems (Guided Weapons ...

Heinkel He 111
The Heinkel He 111 is a German airliner and bomber designed by Siegfried and Walter Günter at Heinkel Flugzeugwerke in 1934. Through development, it was described as a "wolf in sheep's clothing". Due to restrictions placed on Germany after the First World War prohibiting bombers, it was presented solely as a civil airliner, although from conception the design was intended to provide the nascent Luftwaffe with a heavy bomber. Perhaps the best-recognised German bomber of World War II due to the distinctive, extensively glazed "greenhouse" nose of the later versions, the Heinkel He 111 was the most numerous Luftwaffe bomber during the early stages of the war. It fared well until it met serious fighter opposition during the Battle of Britain, when its defensive armament was found to be inadequate. As the war progressed, the He 111 was used in a wide variety of roles on every front in the European theatre. It was used as a strategic bomber during the Battle of Britain, a torpedo bo ...

Battle Of Britain (film)
''Battle of Britain'' is a 1969 British war film directed by Guy Hamilton, and produced by Harry Saltzman and S. Benjamin Fisz. The film documents the events of the Battle of Britain. The film drew many respected British actors to accept roles as key figures of the battle, including Laurence Olivier as Air Chief Marshal Sir Hugh Dowding, Trevor Howard as Air Vice-Marshal Keith Park, and Patrick Wymark as Air Vice-Marshal Trafford Leigh-Mallory. It also starred Michael Caine, Christopher Plummer, and Robert Shaw as Squadron Leaders. The script by James Kennaway and Wilfred Greatorex was based on the book ''The Narrow Margin'' by Derek Wood and Derek Dempster. The film endeavoured to be an accurate account of the Battle of Britain, when in the summer and autumn of 1940 the British RAF inflicted a strategic defeat on the ''Luftwaffe'' and so ensured the cancellation of Operation Sea Lion, Adolf Hitler's plan to invade Britain. The film is notable for its spectacular flying se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
War Film
War film is a film genre concerned with warfare, typically about naval, air, or land battles, with combat scenes central to the drama. It has been strongly associated with the 20th century. The fateful nature of battle scenes means that war films often end with them. Themes explored include combat, survival and escape, camaraderie between soldiers, sacrifice, the futility and inhumanity of battle, the effects of war on society, and the moral and human issues raised by war. War films are often categorized by their milieu, such as the Korean War; the most popular subject is the Second World War. The stories told may be fiction, historical drama, or biographical. Critics have noted similarities between the Western and the war film. Nations such as China, Indonesia, Japan, and Russia have their own traditions of war film, centred on their own revolutionary wars but taking varied forms, from action and historical drama to wartime romance. Subgenres, not necessarily distinct, includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oerlikon Contraves
Rheinmetall Air Defence AG is a division of German armament manufacturer Rheinmetall, created when the company's Oerlikon Contraves unit was renamed on 1 January 2009 and integrated with Rheinmetall's other air-defence products. Oerlikon Contraves was a Swiss anti-aircraft artillery manufacturer famous for its adaptation of the 1916 20 mm Becker as the Oerlikon 20 mm autocannon design, which was used in the Second World War and still in use today.

Rotol
Dowty Propellers is a British engineering company based in Brockworth, Gloucestershire that specialises in the manufacture, repair and overhaul of propellers and propeller components for customers around the world. It is owned by General Electric, forming part of its GE Aviation Systems division. History The company was formed as Rotol Airscrews in 1937 by Rolls-Royce and Bristol Engines to take over both companies' propeller development, the market being too small to support more than one company. The name is a contraction of "ROlls-Royce" and "BrisTOL". Rotol's propellers were always considered leading edge, its models equipping the Hawker Hurricane, Supermarine Spitfire, and many other Second World War-era aircraft. By the end of the war it had introduced the first five-bladed propeller to see widespread use, used on late-model Spitfires. In 1943 the company changed its name from Rotol Airscrews Limited to Rotol Limited, and in 1952 it acquired British Messier Limited, a ...

Rolls-Royce Merlin
The Rolls-Royce Merlin is a British liquid-cooled V-12 piston aero engine of 27-litres (1,650 cu in) capacity. Rolls-Royce designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12, it was later called ''Merlin'' following the company convention of naming its four-stroke piston aero engines after birds of prey. After several modifications, the first production variants of the PV-12 were completed in 1936. The first operational aircraft to enter service using the Merlin were the Fairey Battle, Hawker Hurricane and Supermarine Spitfire. The Merlin remains most closely associated with the Spitfire and Hurricane, although the majority of the production run was for the four-engined Avro Lancaster heavy bomber. A series of rapidly-applied developments, brought about by wartime needs, markedly improved the engine's performance and durability. Starting at 1,000 hp for the first production models, most late war versions produced just ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Zoo December 2019 020 (Hispano Aviación HA-1112 Buchón)
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in Ea ...
