RB199
The Turbo-Union RB199 is a turbofan jet engine designed and built in the early 1970s by Turbo-Union, a joint venture between Rolls-Royce, MTU and Aeritalia. The only production application was the Panavia Tornado. Design and development The RB199 originated with a requirement, in 1969, to power a new European multirole combat aircraft(MRCA) called the Panavia MRCA. The engine requirements to meet the Panavia MRCA specification were significant advances over current engines in thrust-to-weight ratio, fuel consumption and size. The final selection of the engine for the MRCA was made between a new European collaboration, Turbo Union, with the RB199, and Pratt & Whitney who proposed the JTF16. The Panavia MRCA would later be called the Panavia Tornado. Advanced engine studies at Bristol Siddeley had already been done to support the BAC/Dassault AFVG and were based on the Pegasus two-spool arrangement. At Rolls-Royce, where the three spool RB211 engine was in development, 3 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panavia Tornado
The Panavia Tornado is a family of twin-engine, variable-sweep wing multirole combat aircraft, jointly developed and manufactured by Italy, the United Kingdom and West Germany. There are three primary Tornado variants: the Tornado IDS ( interdictor/strike) fighter-bomber, the suppression of enemy air defences Tornado ECR (electronic combat/reconnaissance) and the Tornado ADV (air defence variant) interceptor aircraft. The Tornado was developed and built by Panavia Aircraft GmbH, a tri-national consortium consisting of British Aerospace (previously British Aircraft Corporation), MBB of West Germany, and Aeritalia of Italy. It first flew on 14 August 1974 and was introduced into service in 1979–1980. Due to its multirole design, it was able to replace several different fleets of aircraft in the adopting air forces. The Royal Saudi Air Force (RSAF) became the only export operator of the Tornado in addition to the three original partner nations. A tri-nation training a ...

MTU Aero Engines
MTU Aero Engines AG is a German aircraft engine manufacturer. MTU develops, manufactures and provides service support for military and civil aircraft engines. MTU Aero Engines was formerly known as MTU München. History While the Munich-based engine manufacturer Rapp Motorenwerke, and subsequently BMW, had produced aircraft engines since 1913, the modern company regards the formal date of its formation as being 1934, the year in which ''BMW Flugmotorenbau GmbH'' was spun-off from BMW. This step was initiated by the Ministry of Aviation in order to disguise the planned rearmament of the Luftwaffe – as a standalone limited company the ''Flugmotorenbau GmbH'' had less strict disclosure requirements. Additionally, BMW aimed at outsourcing the unforeseeable risk of contributing to the German rearmament. In 1936, BMW built an aircraft engine plant in Allach near Munich, which are the headquarters of MTU Aero Engines today. In 1940, the plant was expanded significantly to start la ...

Eurofighter Typhoon
The Eurofighter Typhoon is a European multinational twin-engine, canard delta wing, multirole fighter. The Typhoon was designed originally as an air-superiority fighter and is manufactured by a consortium of Airbus, BAE Systems and Leonardo that conducts the majority of the project through a joint holding company, Eurofighter Jagdflugzeug GmbH. The NATO Eurofighter and Tornado Management Agency, representing the UK, Germany, Italy and Spain, manages the project and is the prime customer. The aircraft's development effectively began in 1983 with the Future European Fighter Aircraft programme, a multinational collaboration among the UK, Germany, France, Italy and Spain. Previously, Germany, Italy and the UK had jointly developed and deployed the Panavia Tornado combat aircraft and desired to collaborate on a new project, with additional participating EU nations. However disagreements over design authority and operational requirements led France to leave the consortium to devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Siddeley
Bristol Siddeley Engines Ltd (BSEL) was a British aero engine manufacturer. The company was formed in 1959 by a merger of Bristol Aero-Engines Limited and Armstrong Siddeley Motors Limited. In 1961 the company was expanded by the purchase of the de Havilland Engine Company and the engine division of Blackburn Aircraft. Bristol Siddeley was purchased by Rolls-Royce Limited in 1966. History Bristol Siddeley Engines Limited was formed by the 1 April 1959 merge of Bristol Aero-Engines and Armstrong Siddeley Motors. These were the aero engine manufacturing companies of the Bristol Aeroplane Company and the Hawker Siddeley Group. The share capital of Bristol Siddeley was held in equal proportions by these two parent organisations. At around the same time Bristol's aircraft manufacturing was being subsumed into the British Aircraft Corporation along with those of English Electric and Vickers-Armstrong. Armstrong Siddeley Motors had been producing aero-engines and motor-cars ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BAe EAP
The British Aerospace EAP (standing for ''Experimental Aircraft Programme'') was a British technology demonstrator aircraft developed by aviation company British Aerospace (BAe) as a private venture. It was designed to research technologies to be used for a future European combat aircraft, and eventually formed the basis for the multinational Eurofighter Typhoon. The EAP has its roots within the earlier ''Agile Combat Aircraft'' (ACA), a collaborative initiative studying advanced technologies to produce more capable fighter aircraft. Upon the announcement of the EAP during October 1983, it was intended to be a multinational European effort; however, neither West Germany or Italy would ultimately contribute financially, thus the programme relied upon a combination of British public and British and European private funding instead. Having been manufactured in sections across multiple facilities, the sole EAP aircraft (serial ''ZF534'') was rolled out during April 1986. Performing ...

Creep (deformation)
In materials science, creep (sometimes called cold flow) is the tendency of a solid material to move slowly or deform permanently under the influence of persistent mechanical stresses. It can occur as a result of long-term exposure to high levels of stress that are still below the yield strength of the material. Creep is more severe in materials that are subjected to heat for long periods and generally increases as they near their melting point. The rate of deformation is a function of the material's properties, exposure time, exposure temperature and the applied structural load. Depending on the magnitude of the applied stress and its duration, the deformation may become so large that a component can no longer perform its function – for example creep of a turbine blade could cause the blade to contact the casing, resulting in the failure of the blade. Creep is usually of concern to engineers and metallurgists when evaluating components that operate under high stresses or hig ...

RAF Tornado F3
The Panavia Tornado Air Defence Variant (ADV) was a long-range, twin-engine interceptor version of the swing-wing Panavia Tornado. The aircraft's first flight was on 27 October 1979, and it entered service with the Royal Air Force (RAF) in 1986. It was also operated by the Italian Air Force (AMI) and the Royal Saudi Air Force (RSAF). The Tornado ADV was originally designed to intercept Soviet bombers as they were traversing across the North Sea with the aim of preventing a successful air-launched nuclear attack against the United Kingdom. In this capacity, it was equipped with a powerful radar and beyond-visual-range missiles; however, initial aircraft produced to the F2 standard lacked radars due to development issues. The F3 standard was the definitive variant used by the RAF, the RSAF and the AMI (which leased RAF aircraft). During its service life, the Tornado ADV received several upgrade programmes which enhanced its aerial capabilities and enabled it to perform the Suppr ...

Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more jet thrust relative to fan thrust are known as ''low-bypass turbofans' ...

Rolls-Royce Limited
Rolls-Royce was a British luxury car and later an aero-engine manufacturing business established in 1904 in Manchester by the partnership of Charles Rolls and Henry Royce. Building on Royce's good reputation established with his cranes, they quickly developed a reputation for superior engineering by manufacturing the "best car in the world". The business was incorporated as Rolls-Royce Limited in 1906, and a new factory in Derby was opened in 1908. The First World War brought the company into manufacturing aero-engines. Joint development of jet engines began in 1940, and they entered production. Rolls-Royce has built an enduring reputation for development and manufacture of engines for defence and civil aircraft. In the late 1960s, Rolls-Royce was adversely affected by the mismanaged development of its advanced RB211 jet engine and consequent cost over-runs, though it ultimately proved a great success. In 1971, the owners were obliged to liquidate their business. The useful p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
