PW100
The Pratt & Whitney Canada PW100 aircraft engine family is a series of turboprops manufactured by Pratt & Whitney Canada. Pratt & Whitney Canada dominates the turboprops market with 89% of the turboprop regional airliner installed base in 2016, leading GE Aviation and Allison Engine Company. Development The engine was first introduced as a technology demonstrator in 1977. The PW100 was first tested in March 1981, made its initial flight in February 1982 on a Vickers Viscount testbed aircraft, and then entered service in December 1984 on a Dash 8 regional aircraft for NorOntair. The PW150 engine was introduced on 24 April 1995, when Bombardier selected the engine for the launch of its de Havilland Dash 8-400 regional turboprop. The PW150 was a higher-power version of the PW100 series, with the low-pressure compressor changed from a single-stage centrifugal compressor to a three-stage axial compressor, and the turbine modified to have improved cooling.

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 later bought by Boeing in 1988, then by Bombardier in 1992; then by Longview Aviation Capital in 2019, reviving the De Havilland Canada brand. Powered by two Pratt & Whitney Canada PW100s, it was developed from the Dash 7 with improved cruise performance and lower operational costs, but without STOL performance. Three sizes were offered: initially the 37–40 seat -100 until 2005 and the more powerful -200 from 1995, the stretched 50–56 seats -300 from 1989, both until 2009, and the 68–90 seats -400 from 1999, still in production. The QSeries are post-1997 variants fitted with active noise control systems. Development Initial development In the 1970s, de Havilland Canada had invested heavily in its Dash 7 project, concentrating on STOL and short-field performance, the company's traditio ...

ATR 72
The ATR 72 is a twin-engine turboprop, short-haul regional airliner developed and produced in France and Italy by aircraft manufacturer ATR (french: Avions de transport régional or it, Aerei da Trasporto Regionale), a joint venture formed by French aerospace company Aérospatiale (now Airbus) and Italian aviation conglomerate Aeritalia (now Leonardo S.p.A.). The number "72" in its name is derived from the aircraft's typical standard seating capacity of 72 passengers. During the 1980s, French aerospace company Aérospatiale and Italian aviation conglomerate Aeritalia merged their work on a new generation of regional aircraft. For this purpose, a new jointly owned company was established, ATR, for the purpose of developing, manufacturing, and marketing their first airliner, which was later designated as the ATR 42. On 16 August 1984, the first model of the series, designated as the ATR 42-300, performed the type's maiden flight. During the mid-1980s, the ATR 72 was develope ...

Turboprop
A turboprop is a turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, 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-air mixture then 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 energy 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 obtained by extracting additional power (beyond that necessary to drive the compressor) from turb ...

Pratt & Whitney Canada
Pratt & Whitney Canada (PWC or P&WC) is a Canada-based aircraft engine manufacturer. PWC's headquarters are in Longueuil, Quebec, just outside Montreal. It is a division of the larger US-based Pratt & Whitney (P&W), itself a business unit of Raytheon Technologies Corporation. United Technologies has given PWC a world mandate for small and medium aircraft engines while P&W's US operations develop and manufacture larger engines. Although PWC is a division of P&W, it does its own research, development and marketing as well as the manufacturing of its engines. The company currently has about 10,000 employees worldwide, with 6,000 of them in Canada. History The Canadian Pratt & Whitney Aircraft Company, Ltd. was founded in November 1928 to act as a service centre for P&W aircraft engines. During World War II, it assembled Pratt & Whitney Wasp series engines built in the U.S. In 1952, the production of Wasp engines was transferred to Canadian Pratt & Whitney so P&W could concentrat ...

Embraer EMB 120 Brasilia
The Embraer EMB 120 Brasilia is a twin-turboprop 30-passenger commuter airliner designed and manufactured by the Brazilian aircraft manufacturer Embraer. The EMB 120 began development during 1974. While initially conceived as a modular series of aircraft, the ''Family 12X'' and referred to as the ''Araguaia'', intending to achieve a high level of commonality with the EMB 121 Xingu, the aircraft was redesigned and relaunched with the ''Brasilia'' name scheme during 1979. The redesign, which drew on operator feedback, reduced the seating capacity somewhat while removing commonality with the EMB 121. Its size, speed, and ceiling enabled faster and more direct services to be flown in comparison to similar aircraft. The EMB 120 features a circular cross-section fuselage, low-mounted straight wings and has a T-tail. On 27 July 1983, the prototype performed its maiden flight. During October 1985, the first EMB 120 entered service with Atlantic Southeast Airlines; it quickly entered s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATR 42
The ATR 42 is a regional airliner produced by Franco-Italian manufacturer ATR, with final assembly in Toulouse, France. On 4 November 1981, the aircraft was launched with ATR, as a joint venture between French Aérospatiale (now Airbus) and Aeritalia (now Leonardo S.p.A.). The ATR 42-300 performed its maiden flight on 16 August 1984 and type certification was granted during September 1985. Launch customer Air Littoral operated its first revenue-earning flight in December of that year. The high-wing airliner is powered by two turboprop engines, Pratt & Whitney Canada PW120s. The number "42" in its name is derived from the aircraft's original standard seating capacity of 42 passengers. Later variants are upgraded with new avionics, a glass cockpit, and newer engine versions. The ATR 42 is the basis for the stretched ATR 72, introduced in October 1989. Development During the 1960s and 1970s, European aircraft manufacturers had, for the most part, undergone considerable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EADS CASA C-295
The CASA C-295 (now Airbus C295) is a medium tactical transport aircraft that was designed and initially manufactured by the Spanish aerospace company CASA. Work on what would become the C-295 was started during the 1990s as a derivative of the successful CASA/IPTN CN-235 transport aircraft. On 28 November 1997, the prototype performed its maiden flight; quantity production commenced shortly thereafter. In April 1999, the Spanish Air Force became its launch customer with an order for nine military-configured C-295s; two years later, the type was declared operational with the service. Further orders for the C-295 would promptly follow. Following the incorporation of CASA into the pan-European aeronautical group EADS in 2000, it was redesignated as the EADS CASA C-295. Both manufacturing and final assembly of the C-295 is normally performed at the Airbus Defence and Space facilities in San Pablo Airport, located in Seville, Spain. Additional manufacturing arrangements have b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fokker 50
The Fokker 50 is a turboprop-powered airliner, designed as an improved version of the successful Fokker F27 Friendship. The Fokker 60 is a stretched freighter version of the Fokker 50. Both aircraft were manufactured and supported by Dutch aircraft manufacturer Fokker. The Fokker 50 was developed during the early 1980s following a decline in the sales of the company's earlier F27 Friendship. It was decided that the new airliner would be a derivative of its predecessor, sharing much of its airframe and design features, while incorporating new advances and several improvements, such as the adoption of Pratt & Whitney Canada PW127B turboprop engines, in order to produce a successor that had a 30 per cent reduction in fuel consumption over the F27. The Fokker 50 performed its maiden flight on 28 December 1985, and entered revenue service during 1987. The Fokker 60 has been operated by the Royal Netherlands Air Force (RNLAF), ex-RNLAF aircraft are also in service with the Peruvia ...

NorOntair
NorOntair, stylized as norOntair, was a Canadian regional airline operating in northern Ontario from October 18, 1971 to March 29, 1996. It was as a subsidiary of the Ontario Northland Transportation Commission (ONTC), a provincial Crown agency of the Government of Ontario, with the stated goal of creating east-west links across northern Ontario. History ONTC's first foray into air services began when it subcontracted flying operations to various airlines including Bradley Air Service (First Air), Austin Airways, Air-Dale Ltd and OnAir (taken over by Bearskin Airlines). Air-Dale Ltd. based in Sault Ste Marie was the airline's main operations base. Two de Havilland Dash 8-102 aircraft and six Dash 6-300 Twin Otters were based in Sault Ste Marie. Two additional Twin Otters were based in Thunder Bay and were operated by Bearskin Airlines crews but painted in full NorOntair colours. In its final years, ONTC bought Air-Dale Ltd and operated all the remaining routes until the service ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombardier Inc
Bombardier Inc. () is a Canadian business jet manufacturer. It was also formerly a manufacturer of commercial jets, public transport vehicles, trains, and recreational vehicles, with the last being spun-off as Bombardier Recreational Products. The company originally produced Ski-doo snowmobiles, over time expanding into the aviation, light and heavy rail, and public transit businesses. Bombardier manufactures several series of corporate jets, Global 7500, Global Express, Challenger 650 and Challenger 3500. History Bombardier Recreational Products In January 1934, a blizzard prevented Joseph-Armand Bombardier from reaching the nearest hospital in time to save his two-year-old son, Yvon, who died from appendicitis complicated by peritonitis. Bombardier was a mechanic who dreamed of building a vehicle that could "float on snow". In 1935, in a repair shop in Valcourt, Quebec, he designed and produced the first snowmobile using a drive system he developed that rev ...
