Pratt And Whitney Canada
Pratt & Whitney Canada (PWC or P&WC) is a Canada-based aircraft engine manufacturer. PWC's headquarters are in Longueuil, Quebec, south of Montreal. It is a division of the larger US-based Pratt & Whitney (P&W), itself a business unit of RTX Corporation. United Technologies had 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 concentrate on developing jet en ...

Pratt & Whitney Canada 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. The PT6 consists of two basic sections: a gas generator with accessory gearbox, and a free-power turbine with reduction gearbox. In aircraft, the engine is often mounted "backwards," with the intake at the rear and the exhaust at the front, so that the turbine is directly connected to the propeller. 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, which 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 turboprop engine c ...

Division (business)
A division, sometimes called a business sector or business unit (segment), is one of the parts into which a business, organization or company is divided. Overview Divisions are distinct parts of a business. If these divisions are all part of the same company, then that company is legally responsible for all of the obligations and debts of the divisions. In the banking industry, an example would be East West Bancorp and its primary subsidiary, East West Bank. Legal responsibility Subsidiaries are separate, distinct Commercial law, legal entities for the purposes of taxation, regulation and Legal liability, liability. For this reason, they differ from divisions, which are businesses fully integrated within the main company, and not legally or otherwise distinct from it. The ''Houston Chronicle'' highlighted that the creation of a division "is substantially easier than developing subsidiaries. Because a division is an internal segment of a company, not an entirely separate enti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fuel Efficiency
Fuel efficiency (or fuel economy) is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical energy, chemical potential energy contained in a carrier (fuel) into kinetic energy or Mechanical work, work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile. Non-transportation applications, such as Industrial sector, industry, benefit from increased fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process. In the context of transport, fuel economy is the energy efficiency in transportation, energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of Motor fuel, fuel consumed. It is dependent on several factors including engine efficiency, transmission (mechanics), transmission design, and tire design. In ...
