Canadair Regional Jet
The Bombardier CRJ or CRJ Series (for Canadair Regional Jet) is a family of regional jets introduced in 1991 by Bombardier Aerospace. The CRJ was formerly manufactured by Bombardier Aerospace with the manufacturing of the first CRJ generation, the CRJ100/200 (introduced in 1991) and the second CRJ generation, the CRJ700 series (introduced in 1999). The CRJ programme was acquired by Japanese corporation Mitsubishi Heavy Industries (MHI RJ Aviation Group) in a deal that closed 1 June 2020. Bombardier subsequently completed assembly of the order backlog on behalf of Mitsubishi. Background Bombardier claims it is the most successful family of regional jets in the world. By October 2018, 1,800 CRJs had been delivered. Production ended in December 2020 after 1,945 were built. The family consists of the following aircraft generations and models/derivatives: * CRJ100/200 ** CL-600-2B19 (Regional Jet Series 100/200/440) – maximum of 50 passenger seats * CRJ700 series ** CL-600-2 ...

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number.

GE CF34
The General Electric CF34 is a civilian high-bypass turbofan developed by GE Aircraft Engines 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. 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 HP compressor driven by a 2-stage high pressure (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 ...

CRJ-700
The Bombardier CRJ700, CRJ900, and CRJ1000 are a family of regional jet airliners that were designed and manufactured by Canadian transportation conglomerate Bombardier (formerly Canadair) between 1999 and 2020. Their design was derived from the smaller CRJ100 and 200 airliners, the other members of the Bombardier CRJ aircraft family. The CRJ program was acquired by Japanese corporation Mitsubishi Heavy Industries in 2020, which ended production of the aircraft. During the 1990s, Bombardier initiated development on the ''CRJ-X'', a program to produce enlarged derivatives of its popular CRJ100/200 family. Officially launched in 1997, the CRJ700's maiden flight took place on 27 May 1999; it was soon followed by the stretched CRJ900 variant. Several additional variants of the type were subsequently introduced, including the elongated CRJ1000 and the CRJ550 and CRJ705 which were modified to comply with scope clauses. Competitors included the British Aerospace 146, the Embraer E- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport Canada
Transport Canada (french: Transports Canada) is the department within the Government of Canada responsible for developing regulations, policies and services of road, rail, marine and air transportation in Canada. It is part of the Transportation, Infrastructure and Communities (TIC) portfolio. The current Minister of Transport is Omar Alghabra. Transport Canada is headquartered in Ottawa, Ontario. History The Department of Transport was created in 1935 by the government of William Lyon Mackenzie King in recognition of the changing transportation environment in Canada at the time. It merged three departments: the former Department of Railways and Canals, the Department of Marine, and the Civil Aviation Branch of the Department of National Defence (c. 1927 when it replaced the Air Board) under C. D. Howe, who would use the portfolio to rationalize the governance and provision of all forms of transportation (air, water and land). He created a National Harbours Board and ...

Mitsubishi SpaceJet
The Mitsubishi SpaceJet (, originally named ''Mitsubishi Regional Jet'') is a regional jet developed by Japanese company Mitsubishi Aircraft Corporation (MAC), a Mitsubishi Heavy Industries (MHI) subsidiary. The airframe is made mainly in aluminium with a carbon fibre composites empennage. The low-wing twinjet is powered by underwing Pratt & Whitney PW1000Gs, and was the first program to select the geared turbofan. The M90 (originally named MRJ90) should seat 86 to 96, while the smaller MRJ70 was to accommodate 70 to 80 passengers. The MRJ70 was replaced by the SpaceJet M100, stretched by 1.1 m (3 ft 7 in) to better meet US scope clauses at 76 seats with premium seating. It is comparable with the Embraer E-Jet E2. 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 rebra ...
