PW800
The Pratt & Whitney Canada PW800 is a turbofan engine in the thrust class, under development by Pratt & Whitney Canada. Intended for the regional jet and business jet market, the gear-less PW800 shares a common core with the larger, geared PW1000G. The first variants were certified on February 15, 2015, to power the new Gulfstream G500/G600. Development The development of the PW800 stretches back to demonstration projects in 1999, soon after the development of the PW600 very light engine and the PW300 business jet engine. After the Advanced Technology Fan Integrator demonstrator first ran on March 17, 2001, which became the PW1000G, Pratt & Whitney Canada was searching for a launch customer for the initially geared PW800, in the thrust range, bridging the gap between P&WC's PW300 and P&W's PW6000, intended for the regional- and business-jet engine market. The PW800 core was to be the basis for the Pratt & Whitney Canada PW180, a turboprop engine proposed for the Airbus A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PW1000G
The Pratt & Whitney PW1000G, also called the Geared Turbofan (GTF), is a high-bypass geared turbofan engine family produced by Pratt & Whitney. After many demonstrators, the program was launched with the Mitsubishi MRJ's PW1200G in March 2008, and it was first flight tested in July 2008. The first variant to be certified was the PW1500G for the Airbus A220 in February 2013. The program cost is estimated at $10 billion. The gearbox between the fan and the low-pressure spool allows each to spin at its optimal speed, allowing a higher bypass ratio for a better propulsive efficiency. Pratt & Whitney claims the engine is 16% more fuel efficient than the previous generation, and up to 75% quieter. The first variant to enter service was the PW1100G for the A320neo in January 2016. The engine had teething problems after its introduction, extending to grounded aircraft and inflight failures, solved afterwards. The variants can generate 15,000 to 33,000 lbf (67 to 147 kN) of thrust. Bes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dassault Falcon 6X
The Dassault Falcon 6X is a large, long-range business jet under development by Dassault Aviation in France. Its precursor, the Falcon 5X twinjet, was launched in 2013, rolled-out in 2015 and made its first flight on July 5, 2017, but its development was frozen as its Safran Silvercrest engine failed to meet performance objectives. In December 2017, the Falcon 6X was launched as a stretched version with PW812D turbofans, made its first flight on 10 March 2021, and is slated to enter service in mid-2023. It has the widest purpose-built business jet cabin at . Its wing allows a maximum weight with engines, for a range and a Mach 0.90 top speed. Development Falcon 5X Design work began in 2006 under the codename ''SMS'' for super-midsize, and was envisioned to compete with the Hawker 4000, the Bombardier Challenger 300 and the Gulfstream G200 or the Embraer Legacy 600 with a range. Few details were publicized, except that the model was to be powered by two 10,000-poun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cessna Citation Columbus
The Cessna Citation Columbus was a business jet project by Cessna, part of the Cessna Citation family. The Model 850 was launched in February 2008 and cancelled in July 2009. It would have been the largest model of the family at the time. Powered by 8,830 lbf (39.3 kN) PW810 turbofans and a range, the $27 million aircraft had a 709 sq ft (66 m2), 30° swept wing. Development Cessna began research on the largest Citation in 2002 with market studies, surveys, concept testing, focus groups and customer advisory boards. A mockup of the large cabin concept was unveiled on October 17, 2006, at the National Business Aviation Association convention Cessna formally announced the aircraft on February 6, 2008 ; FAA certification was planned by the end of 2013, with deliveries beginning in 2014. The Columbus had a target range of with 8 passengers. The cockpit would have featured a synthetic vision system, autothrottles, optional head-up display and Collins' MultiScan weather ...

Business Jet
A business jet, private jet, or bizjet is a jet aircraft designed for transporting small groups of people. Business jets may be adapted for other roles, such as the evacuation of casualties or express parcel deliveries, and some are used by public bodies, government officials or the armed forces. History Early developments The first small jet-powered civil aircraft was the Morane-Saulnier MS.760 Paris, developed privately in the early 1950s from the Morane-Saulnier MS.755 Fleuret, MS.755 Fleuret two-seat jet trainer. First flown in 1954, the MS.760 Paris differs from subsequent business jets in having only four seats arranged in two rows without a center aisle, similar to a light aircraft, under a large sliding canopy (aircraft), canopy similar to that of a fighter aircraft, fighter. A U.S. type certificate was awarded in July 1958, but commercial sales were limited, with most examples going to the military; an improved civil version similar to a modern very light jet, with a ...

Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

Europrop TP400
The Europrop International TP400-D6 is an 11,000 shp (8,200 kW) powerplant, developed and produced by Europrop International for the Airbus A400M Atlas military transport aircraft. The TP400 is the most powerful turboprop in service using a single propeller; only the Kuznetsov NK-12 using contra-rotating propellers is larger. Development The TP400 was originally selected by Airbus Military to power the A400M in December 2000. However, Airbus reopened the engine competition in February 2002, because the engine core, which is based on the Snecma M88 turbofan fighter engine, was too heavy and used too much fuel. By May 2002, Pratt & Whitney Canada (P&WC) announced a proposal involving a turboprop with a core based on its PW800 turbofan, a regional jet engine under development that had a geared fan at the time; the concept would later be called the PW180. In 2003, around the 30 April decision deadline, Airbus Chief Executive Noel Forgeard told reporters that the P&WC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Snecma Silvercrest
The Safran Silvercrest is a French turbofan under development by Safran Aircraft Engines. Development The engine was announced at the 2006 National Business Aviation Association convention. Certification was originally slated for the end of 2010 or early 2011. In early 2008 the high pressure spool and combustor have been run in a US$120 million core-demonstrator called SM-X, reaching the take-off speed of 20,300rpm. The First Engine To Test started ground testing in September 2012. In May 2013, in-flight tests were targeted for the fourth quarter of the year. They finally started in July 2014 on a Grumman Gulfstream II and should take place in Istres-Le Tubé Air Base. In 2015, engine certification was rescheduled for late 2016. In 2015, Safran passed €654 million of depreciation for amortization for the Silvercrest program. In November 2016, issues were traced to airflow through the engine not as controlled as expected, a side-effect of the axial-centrifugal high-pressur ...
