Armstrong Siddeley Adder
The Armstrong Siddeley ASA.1 Adder was an early British turbojet engine developed by the Armstrong Siddeley company and first run in November 1948. Design and development The Adder, a turbojet derivative of the Armstrong Siddeley Mamba, was originally developed as an expendable engine to power the Jindivik 1 target drone. The engine was then developed into a longer-life engine before evolving into the more-powerful Armstrong Siddeley Viper. The ASA.1 Adder was flight tested in the rear-turret position of the Avro Lancaster III ''SW342'', the aircraft also having been previously modified and used for icing trials of the Mamba by Armstrong Siddeley's Flight Test Department at Bitteswell.

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

Armstrong Siddeley
Armstrong Siddeley was a British engineering group that operated during the first half of the 20th century. It was formed in 1919 and is best known for the production of luxury vehicles and aircraft engines. The company was created following the purchase by Armstrong Whitworth of Siddeley-Deasy, a manufacturer of fine motor cars that were marketed to the top echelon of society. After the merge of companies, this focus on quality continued throughout in the production of cars, aircraft engines, gearboxes for tanks and buses, rocket and torpedo motors, and the development of railcars. Company mergers and takeovers with Hawker Aviation and Bristol Aero Engines saw the continuation of the car production which ceased in August 1960. The company was absorbed into the Rolls-Royce conglomerate which was interested in the aircraft and aircraft engine business. Eventually, the remaining spares and all motor car interests were sold to the Armstrong Siddeley Owners Club Ltd, which now own ...

Armstrong Siddeley Mamba
The Armstrong Siddeley Mamba was a British turboprop engine produced by Armstrong Siddeley in the late 1940s and 1950s, producing around 1,500 effective horsepower (1,100 kW). Armstrong Siddeley gas turbine engines were named after snakes. Design and development The Mamba was a compact engine with a 10-stage axial compressor, six combustion chambers and a two-stage power turbine. The epicyclic reduction gearbox was incorporated in the propeller spinner. Engine starting was by cartridge. The Ministry of Supply designation was ASMa (Armstrong Siddeley Mamba). The ASMa.3 gave 1,475 ehp and the ASMa.6 was rated at 1,770 ehp. A 500-hour test was undertaken in 1948 and the Mamba was the first turboprop engine to power the Douglas DC-3, when in 1949, a Dakota testbed was converted to take two Mambas. The Mamba was also developed into the form of the Double Mamba, which was used to power the Fairey Gannet anti-submarine aircraft for the Royal Navy. This was essentially two M ...

Armstrong Siddeley Viper
The Armstrong Siddeley Viper is a British turbojet engine developed and produced by Armstrong Siddeley and then by its successor companies Bristol Siddeley and Rolls-Royce Limited. It entered service in 1953 and remained in use with the Royal Air Force, powering its Dominie T1 navigation training aircraft until January 2011. Design and development The design originally featured a seven-stage compressor based on their Adder engine — the Viper is in effect a large-scale Adder. Like the similar J85 built in United States, the Viper was originally developed as an expendable engine for production versions of the Jindivik target drone. Like the J85, the limited-life components and total-loss oil systems were replaced with standard systems for use in crewed aircraft. Because it was initially developed as an expendable engine, the Viper was subject to many recurring maintenance issues. This led to the development of the first Power by the Hour program in which operators woul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people.

GAF Jindivik
The GAF Jindivik is a radio-controlled target drone produced by the Australian Government Aircraft Factories (GAF). The name is from an Aboriginal Australian word meaning "the hunted one". Two manually-controlled prototypes, were built as the GAF Pika (Project C) as a proof of concept to test the aerodynamics, engine and radio control systems, serialled ''A92-1/2'', 'B-1/2'. The radio-controlled Jindivik was initially designated the Project B and received serials in the A93 series. Pika is an Aboriginal Australian word meaning ''flier''. Design and development The Jindivik was developed as a result of a bilateral agreement between Australia and the UK regarding guided missile testing. While the UK provided the missiles, Australia provided test facilities, such as the Woomera Test Range. As a result of the talks, Australia gained the contract for developing a target drone to Ministry of Supply specification E.7/48. The specification called for an aircraft capable of a 15-minute s ...

Avro Lancaster
The Avro Lancaster is a British Second World War heavy bomber. It was designed and manufactured by Avro as a contemporary of the Handley Page Halifax, both bombers having been developed to the same specification, as well as the Short Stirling, all three aircraft being four-engined heavy bombers adopted by the Royal Air Force (RAF) during the same wartime era. The Lancaster has its origins in the twin-engine Avro Manchester which had been developed during the late 1930s in response to the Air Ministry Specification P.13/36 for a medium bomber for "world-wide use" which could carry a torpedo internally, and make shallow dive-bombing attacks. Originally developed as an evolution of the Manchester (which had proved troublesome in service and was retired in 1942), the Lancaster was designed by Roy Chadwick and powered by four Rolls-Royce Merlins and in one of the versions, Bristol Hercules engines. It first saw service with RAF Bomber Command in 1942 and as the strategic bom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitteswell
Bitteswell is a small village and former civil parish, now in the parish of Bitteswell with Bittesby, in the Harborough district of Leicestershire in England. It is situated just north of the town of Lutterworth, and in the 2001 census had a population of 454 (including Magna Park). The population had increased to 554 at the 2011 census. It was recorded in the Domesday Book as Betmeswelle. The village's name means 'the spring/stream in the broad valley'. History The village contains two thatched houses and a number of Georgian dwellings alongside modern houses. Population figures have not altered much since records began in 1801 with a population of 398 was recorded as against around 380 today. In 1841 there was a big increase caused by the building of Bitteswell Hall, north of the village. This brought employment and new families as it had its own farms, gas installation etc., but in the 1920s it was demolished, the land and buildings split up. The village also had its own ...

Saab 210
The Saab 210 is an approximately 70% scale research prototype for the double-delta configuration of the Saab 35 Draken supersonic fighter. Although never officially named anything but Draken by Saab, it soon became known by its unofficial nickname Lilldraken (Little Dragon) after the first flight of the prototype of the Saab 35. Its first flight was on 21 January 1952. Design and development Under designer Erik Bratt, in the early 1950s Saab were developing a double-delta configuration for a proposed supersonic jet fighter. The configuration was novel and highly advanced, so a small aerodynamic test aircraft, the Type 210, was built to investigate its low-speed flight characteristics.Forsgren (2010) 210 or 210A The tailless double-delta wing extended almost to the front of the 210, with the integral wing root air intakes positioned just behind a small nose. The 210 also featured a protruding bubble canopy, a swept tail fin and semi-retractable tricycle undercarriage. By now the ...
