Avro Rj85
The British Aerospace 146 (also BAe 146) is a short-haul and regional airliner that was manufactured in the United Kingdom by British Aerospace, later part of BAE Systems. Production ran from 1983 until 2001. Avro International Aerospace manufactured an improved version known as the Avro RJ. Production for the Avro RJ version began in 1992. Later on, a further-improved version with new engines, the Avro RJX, was announced in 1997, but only two prototypes and one production aircraft were built before production ceased in 2001. With 387 aircraft produced, the Avro RJ/BAe 146 is the most successful British civil jet airliner programme. The BAe 146/Avro RJ is a high-wing cantilever monoplane with a T-tail. It has four geared turbofan engines mounted on pylons underneath the wings, and has a retractable tricycle landing gear. The aircraft operates very quietly, and as such has been marketed under the name Whisperjet. It sees wide usage at small, city-based airports such as London C ...

Geared Turbofan
The geared turbofan is a type of turbofan aircraft engine with a planetary gearbox between the low pressure compressor / turbine and the fan, enabling each to spin at its optimum speed. The benefit of the design is lower fuel consumption and much quieter operation. The drawback is that it increases weight and adds complexity. Technology In a conventional turbofan, a single shaft (the "low-pressure" or LP shaft) connects the fan, the low-pressure compressor and the low-pressure turbine (a second concentric shaft connects the high-pressure compressor and high-pressure turbine). In this configuration, the maximum tip speed for the larger radius fan limits the rotational speed for the LP shaft and thus the LP compressor and turbine. At high bypass ratios (and thus also high radius ratios) the rotational speed of the LP turbine and compressor must be relatively low, which means extra compressor and turbine stages are required to keep the average stage loadings and, therefore, overa ...

Lycoming ALF 502
The Lycoming ALF 502/LF 507 (later Honeywell ALF 502/LF 507) is a geared turbofan Aircraft engine, engine produced by Lycoming Engines, AlliedSignal, and Honeywell Aerospace. The U.S. military designation for the ALF 502 is YF102. Development In mid-1970, Avco Lycoming was advertising two Lycoming T55-derived engines, an LTC4B-12 turboprop and an ALF 502A turbofan, as possible powerplants for the U.S. Air Force's A-X close air support aircraft program. Northrop Corporation signed a contract with Avco Lycoming to use the ALF 502A for its entry into the A-X competition, the Northrop YA-9, in January 1971. The engine was given a United States military aircraft engine designation of YF102-LD-100. Six YF102 engines were built for the YA-9. The thrust engines powered the A-9A prototypes for seven months of flight tests in 1972, recording 238 flights and 652 flight hours. These engines were later reused in the C-8A Quiet Short-Haul Research Aircraft (QSRA). The commercial ALF 502D e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing 737
The Boeing 737 is an American narrow-body aircraft, narrow-body aircraft produced by Boeing at its Boeing Renton Factory, Renton factory in Washington (state), Washington. Developed to supplement the Boeing 727 on short and thin routes, the twinjet retained the Boeing 707, 707 fuselage width and six abreast seating but with two underwing Pratt & Whitney JT8D low-bypass turbofan engines. Envisioned in 1964, the initial 737-100 made its first flight in April 1967 and entered service in February 1968 with Lufthansa. The lengthened 737-200 entered service in April 1968, and evolved through four generations, offering several variants for 85 to 215 passengers. The First Generation 737-100/200 variants were powered by Pratt & Whitney JT8D low-bypass turbofan engines and offered seating for 85 to 130 passengers. Launched in 1980 and introduced in 1984, the Second Generation Boeing 737 Classic, 737 Classic -300/400/500 variants were re-engine, upgraded with more fuel-efficient CFM In ...

BAC One-Eleven
The BAC One-Eleven (BAC-111, BAC 1-11) is a retired early jet airliner produced by the British Aircraft Corporation (BAC). Conceived by Hunting Aircraft as a 30-seat jet, before its merger into BAC in 1960, it was launched as an 80-seat airliner with a British United Airways (BUA) order on 9 May 1961. The prototype conducted its maiden flight on 20 August 1963, and it was first delivered to BUA on 22 January 1965. The 119-seat, stretched 500 series was introduced in 1967. Total production amounted to 244 until 1982 in the United Kingdom including 1982 to 1989 in Romania where nine Rombac One-Elevens were licence-built by Romaero. The short haul, narrowbody aircraft was powered by aft-mounted Rolls-Royce Spey low-bypass turbofans, a configuration similar to the earlier Sud Aviation Caravelle and later McDonnell Douglas DC-9, Douglas DC-9. It competed with early Boeing 737 models and was used by British, US, and European airlines, including Romanian operators. It was replaced ...

Fokker F27 Friendship
The Fokker F27 Friendship is a turboprop airliner developed and manufactured by the Dutch aircraft manufacturer Fokker. It is the most numerous post-war aircraft manufactured in the Netherlands; the F27 was also one of the most successful European airliners of its era. The F27 was developed during the early 1950s with the intent of producing a capable successor to the earlier piston engine-powered airliners that had become commonplace on the market, such as the Douglas DC-3. A key innovation of the F27 was the adoption of the Rolls-Royce Dart turboprop engine, which produced substantially less vibration and noise which provided improved conditions for passengers; another major comfort feature was cabin pressurisation. Innovative manufacturing techniques were also employed in the aircraft's construction. On 24 November 1955, the F27 made its maiden flight; on 19 November 1958, the type was introduced to revenue service. Shortly after its introduction, the F27 was recognised as ...

Turboprop
A turboprop is a Gas turbine, gas turbine engine that drives an aircraft Propeller (aeronautics), propeller. A turboprop consists of an intake, reduction drive, reduction gearbox, gas compressor, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the Fuel mixture, fuel-air mixture then Combustion, combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough power to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawker Siddeley
Hawker Siddeley was a group of British manufacturing companies engaged in list of aircraft manufacturers, aircraft production. Hawker Siddeley combined the legacies of several British aircraft manufacturers, emerging through a series of mergers and acquisitions as one of only two such major British companies in the 1960s. In 1977, Hawker Siddeley became a founding component of the nationalised British Aerospace (BAe). Hawker Siddeley also operated in other industrial markets, such as locomotive building (through its ownership of Brush Traction) and diesel engine manufacture (through its ownership of Lister Petter). The company was once a constituent of the FTSE 100 Index. History Origins Hawker Siddeley Aircraft was formed in 1935 as a result of the purchase by Hawker Aircraft of the companies of John Siddeley, 1st Baron Kenilworth, J. D. Siddeley, the automotive and engine builder Armstrong Siddeley and the aircraft manufacturer Armstrong Whitworth Aircraft. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gravel Kit
A gravel kit is a modification on an aircraft to avoid foreign object debris (FOD) damage or ingestion while operating on unpaved surfaces. Modifications generally include methods of preventing the nose gear spraying FOD into the engine and onto the underside of the fuselage or wings, and methods of preventing each engine from ingesting FOD from the ground directly in front of it. Examples of planes that can be fitted with this upgrade include the Boeing 737-200, which includes a gravel deflector (similar in appearance to a wide ski) mounted to the nose wheel, and vortex dissipators, using compressor bleed air, in front of each engine. This modification was used by Alaska Airlines for many years, and is still employed by Air Inuit, Canadian North, Air North, Nolinor Aviation in northern Canada. Some Boeing 727s were also fitted with specific gravel kits on the nose wheel, while the rest were fitted with devices in the form of smaller deflectors than those used on the 737, used on ...

Business Jet
A business jet, private jet, or bizjet is a jet aircraft designed for transporting small groups of people, typically business executives and high-ranking coworker, associates. Business jets are generally designed for faster air travel and more personal comfort than commercial aircraft, and may be adapted for other roles, such as casualty evacuation or express package delivery, parcel deliveries, and some are used by public bodies, government officials, very important person, VIPs, or even the military. History Early developments The first small, jet-powered civilian aircraft was the Morane-Saulnier MS.760 Paris, developed privately in the early 1950s from the Morane-Saulnier MS.755 Fleuret, MS.755 Fleuret two-seat jet trainer. First flown in 1954, the MS.760 Paris differs from subsequent business jets in having only four seats arranged in two rows without a center aisle, similar to a light aircraft, under a large sliding canopy (aircraft), canopy similar to that of a fighter ...
