The Pratt & Whitney Canada PW500 is a series of medium thrust turbofan engines designed specifically for business jet applications.

Contents

Design

The PW530 has a single stage fan, driven by a 2-stage LP turbine, supercharging a 2A/1CF axial-centrifugal HP compressor, driven by a single stage HP turbine. Although similar in configuration, the PW535 has a booster stage, mounted on the LP shaft behind the fan, to increase overall pressure ratio and core flow. Similar to the PW535, the PW545 has an additional LP turbine stage to drive a larger diameter fan.

The PW530A, rated at 2,887 lbf (12.84 kN), entered service in February 1997 on the Cessna Citation II Bravo, and the PW545 in July 1998 on the Cessna Citation Excel. The PW535 powered the Cessna Citation V Encore in September 2000, and was selected for the Embraer Phenom 300, first delivered in December 2009.

On 31 January 2020, Embraer announced improvements to its Phenom 300, including increased speeds and upgraded engines. [3] The engines, designated PW535E1, are rated at 3,478 lbf (15.47 kN)/ [4]

Unveiled at the May 2023 EBACE show, the FADEC-controlled PW545D is developed for the Cessna 560XL Ascend variant, to be rated at 4,200 lbf (19 kN) and optimized for improved fuel burn and longer time between overhauls (TBO) up to 6,000 hours. [2] By then, 4,600 PW500s had been produced and had flown 22 million hours. [2]

A business jet, private jet, or bizjet is a jet aircraft designed for transporting small groups of people, typically business executives and high-ranking associates. Business jets are generally designed for faster air travel and more personal comfort than commercial aircraft, and may be adapted for other roles, such as casualty evacuation or express parcel deliveries, and some are used by public bodies, government officials, VIPs, or even the armed forces.

The Aviadvigatel PS-90 is a Russian high-bypass commercial turbofan rated at 16000 kgf thrust. It powers Russian airliners such as the Ilyushin Il-96 and the Tupolev Tu-204/Tu-214 series and transport aircraft such as the Ilyushin Il-76. It is made by the Russian aircraft engine company Aviadvigatel, which is the successor of the Soviet Soloviev Design Bureau. "PS" are the initials of Pavel Soloviev.

The Rolls-Royce Pegasus, formerly the Bristol Siddeley Pegasus, is a British turbofan engine originally designed by Bristol Siddeley. It was manufactured by Rolls-Royce plc. The engine is not only able to power a jet aircraft forward, but also to direct thrust downwards via swivelling nozzles. Lightly loaded aircraft equipped with this engine can manoeuvre like a helicopter. In particular, they can perform vertical takeoffs and landings. In US service, the engine is designated F402.

<span class="mw-page-title-main">Pratt & Whitney Canada PT6</span> Turboprop aircraft engine family by Pratt & Whitney Canada

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 covers the power range between 580 and 1,940 shp, while the PT6B/C are turboshaft variants for helicopters.
