Bombardier CRJ700
The Bombardier CRJ700 series is a family of regional jet airliners that were designed and manufactured by Canadian transportation conglomerate Bombardier (formerly Canadair). Officially launched in 1997, the CRJ700 made its maiden flight on 27 May 1999, and was soon followed by the stretched CRJ900 variant. Several additional models were introduced, including the further elongated CRJ1000 and the CRJ550 and CRJ705, which were modified to comply with scope clauses. In 2020, the Mitsubishi Aircraft Corporation acquired the CRJ program and subsequently ended production of the aircraft. Development of the CRJ700 series was launched in 1994 under the ''CRJ-X'' program, aimed at creating larger variants of the successful CRJ100 and 200, the other members of the Bombardier CRJ-series. Competing aircraft included the British Aerospace 146, the Embraer E-Jet family, the Fokker 70, and the Fokker 100. In Bombardier’s product lineup, the ''CRJ-Series'' was marketed alongside the larg ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

British Aerospace 146
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 Cit ...

Wind Tunnel
A wind tunnel is "an apparatus for producing a controlled stream of air for conducting aerodynamic experiments". The experiment is conducted in the test section of the wind tunnel and a complete tunnel configuration includes air ducting to and from the test section and a device for keeping the air in motion, such as a fan. Wind tunnel uses include assessing the effects of air on an aircraft in flight or a ground vehicle moving on land, and measuring the effect of wind on Building, buildings and bridges. Wind tunnel test sections range in size from less than a foot across, to over , and with air speeds from a light breeze to hypersonic. The earliest wind tunnels were invented towards the end of the 19th century, in the early days of aeronautical research, as part of the effort to develop heavier-than-air flying machines. The wind tunnel reversed the usual situation. Instead of the air standing still and an aircraft moving, an object would be held still and the air moved around it. ...

High-lift Device
In aircraft design and aerospace engineering, a high-lift device is a component or mechanism on an aircraft's wing that increases the amount of lift produced by the wing. The device may be a fixed component, or a movable mechanism which is deployed when required. Common movable high-lift devices include wing flaps and slats. Fixed devices include leading-edge slots, leading edge root extensions, and boundary layer control systems. Purpose The size and lifting capacity of a fixed wing is chosen as a compromise between differing requirements. For example, a larger wing will provide more lift and reduce the distance and speeds required for takeoff and landing, but will increase drag, which reduces performance during the cruising portion of flight. Modern passenger jet wing designs are optimized for speed and efficiency during the cruise portion of flight, since this is where the aircraft spends the vast majority of its flight time. High-lift devices compensate for this design t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Leading-edge Extension
A leading-edge extension (LEX) is a small extension to an aircraft wing surface, forward of the leading edge. The primary reason for adding an extension is to improve the airflow at high angles of attack and low airspeeds, to improve handling and delay the stall. A dog tooth can also improve airflow and reduce drag at higher speeds. Leading-edge slat A leading-edge slat is an aerodynamic surface running spanwise just ahead of the wing leading edge. It creates a leading edge slot between the slat and wing which directs air over the wing surface, helping to maintain smooth airflow at low speeds and high angles of attack. This delays the stall, allowing the aircraft to fly at a higher angle of attack. Slats may be made fixed, or retractable in normal flight to minimize drag. Dogtooth extension A dogtooth is a small, sharp zig-zag break in the leading edge of a wing. It is usually used on a swept wing, to generate a vortex flow field to prevent separated flow from progressi ...

General Electric CF34
The General Electric CF34 is a civilian high-bypass turbofan developed by GE Aviation from its TF34 military engine. The CF34 is used on a number of business and regional jets, including the Bombardier CRJ series, the Embraer E-Jets, and Comac ARJ21/C909. In 2012, there were 5,600 engines in service. Design and development The original engine contained a single stage fan driven by a 4-stage low pressure (LP) turbine, supercharging a 14-stage high pressure (HP) compressor driven by a 2-stage HP turbine, with an annular combustor. Later higher thrust versions of the CF34 feature an advanced technology core, with only 10 HP compressor stages. Latest variants, the and , were derived from the CFM56 engine family, and have a radically different HP spool, containing a 9-stage compressor driven by a single stage turbine. The LP spool has 3 core booster stages behind the fan. Static thrust is for the variant. On wing times can reach 14,000 hours, an overhaul costs over $1. ...

Bombardier Aerospace
Bombardier Aviation, a division of Bombardier Inc., is headquartered in Dorval, Quebec, Canada. The company currently produces the Global and Challenger series of business jets. At its peak, Bombardier operated manufacturing plants in 27 countries and employed over 70,000 workers. However, under financial pressure, it significantly reduced its workforce and divested its entire commercial aircraft portfolio including the Q-Series regional turboprop, CRJ-Series of regional jets, and the C-Series narrowbody jet. History Early activities Bombadier acquired the state-owned Canadair from the government of Canada in 1986 and restored it to profitability. Canadair had been nationalized in 1976. In 1989, Bombardier acquired the near-bankrupt Short Brothers aircraft manufacturing company in Belfast, Northern Ireland. This was followed in 1990 by the acquisition of the bankrupt American company Learjet, a manufacturer of business jets headquartered in Wichita, Kansas. ...

Mitsubishi SpaceJet
The Mitsubishi SpaceJet (, originally named ''Mitsubishi Regional Jet'') was a regional jet project by Japanese company Mitsubishi Aircraft Corporation (MAC), a Mitsubishi Heavy Industries (MHI) subsidiary. MHI first announced the concept in June 2007, then targeting certification for 2012, as the first Japanese airliner since the 1962 NAMC YS-11. After a delayed development, the maiden flight of the MRJ90 took place on 11 November 2015. In June 2019, Mitsubishi rebranded the Mitsubishi Regional Jet (MRJ, ) program as the SpaceJet. As flight testing took longer than expected, the scheduled entry into service was further pushed back until development was first paused in October 2020, and subsequently cancelled altogether in February 2023. The airframe was made mainly in aluminium with a carbon fibre composite empennage. The low-wing twinjet was powered by underwing Pratt & Whitney PW1000Gs, and was the first program to select the geared turbofan. The M90 (originally named MRJ9 ...

De Havilland Canada Dash 8
The De Havilland Canada DHC-8, commonly known as the Dash 8, is a series of turboprop-powered regional airliners, introduced by de Havilland Canada (DHC) in 1984. DHC was bought by Boeing in 1986, then by Bombardier in 1992, then by Longview Aviation Capital in 2019; Longview revived the De Havilland Canada brand. Powered by two Pratt & Whitney Canada PW150s, it was developed from the Dash 7 with improved cruise performance and lower operational costs, but without STOL performance. The Dash 8 was offered in four sizes: the initial Series 100 (1984–2005), the more powerful Series 200 (1995–2009) with 37–40 seats, the Series 300 (1989–2009) with 50–56 seats, and Series 400 (1999–2022) with 68–90 seats. The QSeries (Q for quiet) are post-1997 variants fitted with active noise control systems.
