Turbomeca Astafan
The Turbomeca Astafan is a single-spool, variable-pitch turbofan engine developed from the Turbomeca Astazou. Despite successful flight-testing, an efficient, quiet and clean design (compared to turbojets and conventional turbofans) and some commercial interest, the Astafan never entered series production. The engines were only flown on the Fouga 90 prototype and Turbomeca's two test aircraft. Design The engine combines an Astazou-derived centrifugal compressor with up to three axial compressor stages (depending on the version of the engine), driven by a common driveshaft. The fan section is composed of a unique variable pitch fan and fixed stator blades mounted at the front of the engine. Blade pitch is varied by a hydraulic piston mounted in the fan hub, while the fan itself is powered via a reduction gear from the main driveshaft. The engine is designed to operate at a constant speed, no matter the thrust output—a characteristic permitted by the Astafan's use of precise fue ...

Piper Aircraft
Piper Aircraft, Inc. is a manufacturer of general aviation aircraft, located at the Vero Beach Regional Airport in Vero Beach, Florida, United States and owned since 2009 by the Government of Brunei. Throughout much of the mid-to-late 20th century, it was considered to be one of the "Big Three" in the field of general aviation manufacturing, along with Beechcraft and Cessna.Pattillo (1998), p. 83 Between its founding in 1927 and the end of 2009, the company produced 144,000 aircraft in 160 certified models, of which 90,000 are still flying. History The company was founded as the Taylor Brothers Aircraft Manufacturing Company in September 1927 by brothers Clarence G. Taylor and Gordon A. Taylor in Rochester, New York. The company was renamed Taylor Brothers Aircraft Corporation in April 1928, shortly before Gordon Taylor died in an aircraft accident flying one of the brothers' own designs, a Taylor Chummy, on April 24, 1928. The company was enticed to move to Bradford ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

IAE SuperFan
The IAE V2500SF SuperFan was a design study for a high-bypass geared turbofan derived from the IAE V2500. It was offered as the primary engine option for the Airbus A340-200 and 300 in January 1987. Although several customers signed preliminary contracts for this variant, the International Aero Engines board decided in April 1987 to stop the development of the SuperFan, which forced Airbus to partly re-design the A340. Development program In July 1986 IAE confirmed to conduct a preliminary design study for a concept examining a high-bypass engine which used the V2500 core components. The engine's projected maximum thrust was 28,000–32,000 lbf while having only 80% of the V2500's specific fuel consumption. Prior to that study the IAE shareholders Rolls-Royce plc, Pratt & Whitney and MTU Aero Engines had examined several configuration for a high-bypass engine, including several design features like a variable fan blade pitch, a geared fan or counterrotating concepts ( ...

Garrett TFE731
The Garrett TFE731 (now Honeywell TFE731) is a family of geared turbofan engines commonly used on business jet aircraft. Garrett AiResearch originally designed and built the engine, which due to mergers was later produced by AlliedSignal and now Honeywell Aerospace. Since the engine was introduced in 1972, over 11,000 engines have been built, flying over 100 million flight-hours. Development The TFE731 was based on the core of the TSCP700, which was developed for use as the auxiliary power unit (APU) on the McDonnell Douglas DC-10. The design featured two important factors: low fuel consumption, and low noise profiles that met the newly established U.S. noise abatement regulations. The first test run of the TFE731 occurred in 1970 at Garrett's plant in Torrance, California. The first production model, the TFE731-2, began rolling off the assembly line in August, 1972, and was used on the Learjet 35/36 and Dassault Falcon 10, both of which entered production in 1973. The TF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney PW1000G
The Pratt & Whitney PW1000G family, also marketed as the Pratt & Whitney GTF (geared turbofan), is a family of high-bypass geared turbofan engines produced by Pratt & Whitney. The various models can generate 15,000 to 33,000 Pound (force), pounds-force (67 to 147 Newton (unit), kilonewtons) of thrust. As of 2025, they are used on the Airbus A220, Airbus A320neo family, and Embraer E-Jet E2. They were also used on new Yakovlev MC-21, Yakovlev MC-21s until exports to Russia were stopped as part of the International sanctions during the Russian invasion of Ukraine, international sanctions during the invasion of Ukraine. Following years of development and testing on various demonstrators, the program officially launched in 2008 with the PW1200G destined for the later-canceled Mitsubishi SpaceJet. The first successful flight test occurred later that year. The PW1500G variant, designed for the A220, became the first certified engine in 2013. P&W is estimated to have spent $10 billion to ...

Honeywell LF 507
The Lycoming ALF 502/LF 507 (later Honeywell ALF 502/LF 507) is a geared turbofan 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 engine was deve ...
