PT6
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada. Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964 and has been continuously updated since. It consists of two basic sections: a gas generator with accessory gearbox and a free power turbine with reduction gearbox, and is often seemingly mounted backwards in an aircraft in so far as the intake is at the rear and the exhaust at the front. Many variants of the PT6 have been produced, not only as turboprops but also as turboshaft engines for helicopters, land vehicles, hovercraft, and boats; as auxiliary power units; and for industrial uses. By November 2015, 51,000 had been produced, had logged 400 million flight hours from 1963 to 2016. It is known for its reliability with an in-flight shutdown rate of 1 per 651,126 hours in 2016. The PT6A covers the power range between while the PT6B/C are turboshaft variants for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney Canada PT6T
The Pratt & Whitney Canada PT6T Twin-Pac is a turboshaft engine designed for helicopters. Manufactured by Pratt & Whitney Canada, its first application was in the Bell 212 and UH-1N Twin Huey helicopter family. The PT6T Twin-Pac consists of two PT6A power turbines driving a common output reduction gearbox, producing up to 2,000 hp at 6,000 rpm. The engine is designated T400 by the U.S. military. Development The U.S. military came very close to not procuring the UH-1N Twin Huey because of the PT6T.Drendel, Lou: ''Huey'', pages 14-17. Squadron/Signal Publications, Carrollton, Texas, 1983. The purchase of the aircraft for U.S. military use was opposed by the Chairman of the House Armed Services Committee at the time, Mendel Rivers. Rivers took this position because the PT6T was produced in Canada. The Canadian government had not supported U.S. involvement in Vietnam, and had opposed U.S. policies in southeast Asia, as well as accepting U.S. draft dodgers. Rivers was al ...

Beech King Air
The Beechcraft King Air is a line of American utility aircraft produced by Beechcraft. The King Air line comprises a number of twin-turboprop models that have been divided into two families. The Model 90 and 100 series developed in the 1960s are known as King Airs, while the later T-tail Model 200 and 300 series were originally marketed as Super King Airs, with the name "Super" being dropped by Beechcraft in 1996 (although it is still often used to differentiate the 200 and 300 series King Airs from their smaller stablemates). The King Air was the first aircraft in its class and was produced continuously from 1964 to 2021. It outsold all of its turboprop competitors combined. It has recently faced competition from jet aircraft such as the Embraer Phenom 100, Honda HA-420 HondaJet and Cessna Citation Mustang; as well as from newer turboprop aircraft including the Piaggio P180 Avanti, and single-engine Piper Malibu Meridian, Pilatus PC-12, and Socata TBM.

De Havilland Canada Dash 7
The de Havilland Canada DHC-7, popularly known as the Dash 7, is a turboprop-powered regional airliner with short take-off and landing (STOL) performance. It first flew in 1975 and remained in production until 1988 when the parent company, de Havilland Canada, was purchased by Boeing in 1986 and later sold to Bombardier. In 2006 Bombardier sold the type certificate for the aircraft design to Victoria-based manufacturer Viking Air. Design and development In the 1960s, de Havilland Canada was already well known worldwide for their series of high-performance STOL aircraft, notably the very popular DHC-2 Beaver and DHC-6 Twin Otter. However, these aircraft were generally fairly small and served outlying routes, as opposed to the busier regional airliner routes which were already well served by larger, higher-performance turboprop aircraft such as the Fokker F27, Fairchild F-27, Convair 580, Convair 600, and Hawker Siddeley 748.

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

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 ...
