Hawker Horsley
The Hawker Horsley was a British single-engined biplane bomber of the 1920s. It was the last all-wooden aircraft built by Hawker Aircraft, and served as a medium day bomber and torpedo bomber with Britain's Royal Air Force between 1926 and 1935, as well as the navies of Greece and Denmark. Design and development The Horsley (named after Sir Thomas Sopwith's home of Horsley Towers) was originally designed to meet Air Ministry Specification 26/23 for a day bomber powered by a single Rolls-Royce Condor engine.. While the specification called for any production aircraft to be of metal construction, Hawker proposed to build the prototype of wooden construction, gradually switching to a metal structure during production. This was acceptable to the Air Ministry, and an order for a single prototype was placed. The first prototype was flown in March 1925, powered by a engine, and was delivered to the Aeroplane and Armament Experimental Establishment at Martlesham Heath on 4 May 1925. ...

Singapore
Singapore (), officially the Republic of Singapore, is a sovereign island country and city-state in maritime Southeast Asia. It lies about one degree of latitude () north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south, the South China Sea to the east, and the Straits of Johor to the north. The country's territory is composed of one main island, 63 satellite islands and islets, and one outlying islet; the combined area of these has increased by 25% since the country's independence as a result of extensive land reclamation projects. It has the third highest population density in the world. With a multicultural population and recognising the need to respect cultural identities of the major ethnic groups within the nation, Singapore has four official languages: English, Malay, Mandarin, and Tamil. English is the lingua franca and numerous public services are available only in Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fife
Fife (, ; gd, Fìobha, ; sco, Fife) is a council area, historic county, registration county and lieutenancy area of Scotland. It is situated between the Firth of Tay and the Firth of Forth, with inland boundaries with Perth and Kinross (i.e. the historic counties of Perthshire and Kinross-shire) and Clackmannanshire. By custom it is widely held to have been one of the major Pictish kingdoms, known as ''Fib'', and is still commonly known as the Kingdom of Fife within Scotland. A person from Fife is known as a ''Fifer''. In older documents the county was very occasionally known by the anglicisation Fifeshire. Fife is Scotland's third largest local authority area by population. It has a resident population of just under 367,000, over a third of whom live in the three principal towns, Dunfermline, Kirkcaldy and Glenrothes. The historic town of St Andrews is located on the northeast coast of Fife. It is well known for the University of St Andrews, the most ancient univers ...

Donibristle
Donibristle ( sco, also Dunibirsle) was a house and estate in Fife, Scotland, on the coast of the Firth of Forth. Only the wings of the house remain, within the modern settlement of Dalgety Bay. They are now protected as a category A listed building. Donibristle was the scene of the killing of James Stewart, 2nd Earl of Moray, in 1592, which is remembered in the ballad "The Bonnie Earl O' Moray". History The first house Around 1540, James Stewart of Doune was made Commendator of Inchcolm Abbey, which is located on an island in the Firth of Forth. Donibristle was then a property of the abbey, and James used it as a residence. In 1580, his son James was raised to the peerage as Lord Doune. Lord Doune's son James Stewart married, in 1581, Elizabeth Stuart, 2nd Countess of Moray, and assumed, ''jure uxoris'' (in right of his wife), the title of the Earl of Moray. Moray quarrelled with George Gordon, 1st Marquess of Huntly, and on 7 February 1592 Huntly attacked and burned Donibrist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairey Fawn
The Fairey Fawn was a British single-engine light bomber of the 1920s. It was designed as a replacement for the Airco DH.9A and served with the Royal Air Force between 1924 and 1929. Development The Fairey Fawn was designed by F Duncanson of Fairey Aviation as a replacement for the Airco DH.9A in the light day-bomber role, to meet the requirements of Specification 5/21 for an aircraft for reconnaissance and army cooperation duties. It was a development of the Fairey Pintail floatplane, powered by a Napier Lion engine. The first of three prototypes flew on 8 March 1923.Mason 1994, p. 148. The second and third prototypes were fitted with lengthened fuselages to improve stability, and this was adapted for the production version.Taylor 1988, pp. 108–109. The Fawn was fitted with fuel tanks above the top wing in order to meet Air Ministry safety requirements. These tanks posed a hazard to the pilots if the aircraft overturned on landing. A revised specification 20/23 was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junkers Jumo 205
The Jumo 205 aircraft engine was the most famous of a series of aircraft diesel engines produced by Junkers. The Jumo 204 first entered service in 1932. Later engines of this type comprised the experimental Jumo 206 and Jumo 208, with the Jumo 207 produced in some quantity for the Junkers Ju 86P and -R high-altitude reconnaissance aircraft, and the 46-meter wingspan, six-engined Blohm & Voss BV 222 ''Wiking'' flying boat. All three of these variants differed in stroke and bore and supercharging arrangements. In all, more than 900 of these engines were produced, in the 1930s and through most of World War II. Design and development These engines all used a two-stroke cycle with 12 pistons sharing six cylinders, piston crown to piston crown in an opposed configuration. This unusual configuration required two crankshafts, one at the bottom of the cylinder block and the other at the top, geared together. The pistons moved towards each other during the operating cycle. The intake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rolls-Royce Eagle
The Rolls-Royce Eagle was the first aircraft engine to be developed by Rolls-Royce Limited. Introduced in 1915 to meet British military requirements during World War I, it was used to power the Handley Page Type O bombers and a number of other military aircraft. The Eagle was the first engine to make a non-stop trans-Atlantic crossing by aeroplane when two Eagles powered the converted Vickers Vimy bomber on the transatlantic flight of Alcock and Brown in June 1919. Background At the outbreak of World War I in August 1914, the Royal Aircraft Factory asked Rolls-Royce to develop a new air-cooled engine. Despite initial reluctance they agreed on condition that it be cooled by water rather than air, as this was the company's area of expertise. Design and development Development of the new 20 litre engine was led by Henry Royce from his home in Kent. Based initially on the 7.4 litre 40/50 Rolls-Royce Silver Ghost engine, and drawing also on the design of a 7.2 litre Daimler ...
