Embraer ERJ Family
The Embraer ERJ family (for Embraer Regional Jet) are regional jets designed and produced by the Brazilian aerospace company Embraer. The family includes the ERJ 135 (37 passengers), ERJ 140 (44 passengers), and ERJ 145 (50 passengers), as well as the Legacy 600 business jet and the R-99 family of military aircraft. Development of the ERJ 145 was launched in 1989. Its early design took the form of a turbofan-powered stretch of the existing turboprop-powered EMB 120 Brasilia regional aircraft. After the project was temporarily suspended in 1990, work on a revised configuration was undertaken during the early 1990s. While retaining the three-abreast seating of the Brasilia, the twinjet featured a new swept wing and is powered by two rear-fuselage-mounted Rolls-Royce AE 3007 turbofans for a range up to . By the time of its maiden flight on 11 August 1995, Embraer had garnered 18 firm orders, 16 options and 127 letters of intent for the type. On 10 Decembe ...

Regional Jet
A regional jet (RJ) is a jet airliner, jet-powered regional airliner usually defined by having fewer than 100 seats. The first aircraft considered part of this category was the Sud-Aviation Caravelle in 1959, followed by Douglas DC-9, BAC One-Eleven, Yakovlev Yak-40, Fokker F28, and BAe 146. The 1990s saw the emergence of the Canadair Regional Jet and Embraer Regional Jet families, followed by the larger Embraer E-Jet and multiple competing projects. This time period also saw the bankruptcy of Fokker in 1996 and departure of BAE Systems from the market in 2001, significantly reducing the number of RJ manufacturers. Market consolidation continued as Bombardier Aviation sold its airliner programs between 2017 and 2019, leaving Embraer as the sole large independent regional jet manufacturer with its Embraer E-Jet E2 family. Comac of China introduced the C909 (at the time ARJ21) jet to fill China's missing regional industry since the retirement of the DC-9. Antonov of Ukraine w ...

Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new type must be certified by a governing agency (such as the Federal Aviation Administration in the United States) before it can enter ...

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 ...

CFE738
The CFE CFE738 is a small turbofan engine aimed at the business/commuter jet market manufactured by the CFE Company, and is used on the Dassault Falcon 2000. Design and development The success of the GE27/GLC38 gas generator development of the 1980s led to the formation of the CFE Company by GE and the Garrett Engine Division of Allied Signal (now Honeywell) in 1987. The CFE738 is a two-shaft design, consisting of a single stage bypass fan connected via one shaft to a 3-stage low-pressure (LP) turbine at the rear of the engine; with a six-stage combination low-pressure/high-pressure (LP/HP) axial/ centrifugal compressor (five axial stages and one centrifugal stage) driven by a two-stage HP turbine, between the fan and the LP turbine, on the other shaft. There is an axial combustion chamber between the compressor stages and the HP turbine. A mixer is built in to the jetpipe to mix cold bypass air with the hot exhaust gases. The engine has an overall pressure ratio of 35:1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Canadair CRJ
The Bombardier CRJ100 and CRJ200 (previously Canadair CRJ100 and CRJ200) are regional jets designed and manufactured by Bombardier Aerospace between 1991 and 2006, the first of the Bombardier CRJ family. The ''Canadair Regional Jet'' (CRJ) program, derived from the Challenger 600 business jet, was launched in early 1989. The first CRJ100 prototype made its maiden flight on 10 May 1991. Canada's first jet airliner to enter commercial service was introduced by launch customer Lufthansa in 1992. The 50 seat aircraft is powered by two GE CF34 turbofans, mounted on the rear fuselage. The CRJ200 has more efficient turbofan engines for lower fuel consumption, increased cruise altitude and speed. During the late 1990s, it was stretched into the CRJ700 series. Production ended in 2006 but many remain in service. In 2020, Mitsubishi Heavy Industries purchased the entire CRJ line from Bombardier, and will continue support for the aircraft. CRJ100 and CRJ200 are marketing designations d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Embraer E-Jet Family
The Embraer E-Jet family is a series of four-abreast, narrow-body aircraft, narrow-body, short- to medium-range, twinjet, twin-engined jet airliners designed and produced by Brazilian aerospace manufacturer Embraer. The E-Jet was designed to complement Embraer’s earlier Embraer ERJ family, ERJ family, the company’s first jet-powered regional aircraft. With a capacity of 66 to 124 passengers, the E-Jets were significantly larger than any aircraft Embraer had developed before that time. The project was unveiled in early 1997 and formally introduced at the 1999 Paris Air Show. On 19 February 2002, the first E-Jet prototype completed its maiden flight, and production began later that year. The first E170 was delivered to LOT Polish Airlines on 17 March 2004. Initial rollout issues were quickly overcome, and Embraer rapidly expanded product support for better global coverage.
