Pratt & Whitney Canada PW600

The Pratt & Whitney Canada PW600 series is a family of very small turbofan engines developed by Pratt & Whitney Canada for use in very light jets. Designed with scalability in mind, the engines can produce between 900 lbf (4,000 N) and 3,000 lbf (13,000 N) of take-off thrust.

A major catalyst in shaping a new era of business aviation. The heart of the exciting new family of very light jets. The PW600 engine is compact, fuel efficient and clean with excellent operating economics.

 

NEWS UPDATE: on July 25, 2012 Pratt & Whitney Canada’s (P&WC) PW610F engine has been selected by Eclipse Aerospace to power the next-generation Eclipse 550 twin-engine business jet. Read the entire press release.

 

First run of the 2,500 lbf (11,000 N) thrust PW625F demonstrator engine was on 31 October 2001. P&WC began work on the 900 lbf (4 kN) thrust PW610F engine, destined for the Eclipse 500, in 2002. The engine was certified by the Canadian authorities on the 27 July 2006. The first Eclipse 500 aircraft, powered by two PW610Fs, was delivered to a customer on 31 December 2006.

With a 14.5 inch (36.83 cm) diameter fan, the PW610F is one of the smallest turbofans to enter production. Little is known about the engine cycle, although the bypass ratio is believed to be about 1.83. Driven by a single-stage low pressure (LP) turbine, the single stage fan is an advanced snubberless design, with wide chord blades integral with the rotor hub. The newly patented high pressure (HP) compressor comprises a diagonal (i.e. mixed) flow stage, supercharging a conventional centrifugal blower, the whole being driven by a single stage HP turbine. A reverse flow combustor and forced mixer/common exhaust are also featured in the design. Dual lane Full Authority Digital Engine Control (FADEC), for smoother, more reliable, operation, is included in the specification. Hispano-Suiza Canada is currently designing and manufacturing the FADEC for this engine.

The larger, 1,350 lbf (6,000 N) thrust, PW615F has a 16 inch (40.64 cm) diameter fan and is aimed at the Cessna Citation Mustang. This engine was certified in December 2005, with first deliveries in March 2006. The Mustang aircraft was certified on 8 September 2006, and deliveries began in 2007. This engine will also be used in the upcoming Eclipse 400, but it will be limited to 1,200 lbf (5,300 N) thrust. Bypass ratio of PW615F amounts to 2.8.

So far, the 1,615 lbf (7,180 N) thrust PW617F, with a 17.6 inch (44.7 cm) diameter fan and bypass ratio of 2.7, is the largest in the family and is designed to power the Embraer Phenom 100. The engine first ran on 29 June 2006, with certification expected in the 4th quarter of 2007. First delivery of a production model is expected in March 2008.

PW600 engines incorporate the latest advanced technologies in the drive to exceed our customers’ expectations in performance, reliability, durability, fuel consumption and environmental friendliness. Three PW600 models are currently available (PW610F, PW615F and PW617F) ranging in thrust from 950 to 1,750 pounds. The engine core developed as a demonstrator earlier this decade has been designed to enable the PW600 family of engines to grow to 3,000 pounds thrust.

The PW600 is a two-spool engine with a two-stage high pressure compressor driven by a single-stage high pressure turbine and a single-stage low pressure turbine driving a robust, advanced technology fan. A high efficiency reverse-flow combustor ensures low emissions and fuel consumption. A high efficiency exhaust mixer further contributes to the engine family’s low fuel burn and noise. Furthermore, the latest Full-Authority Digital Engine Control (FADEC) provides reduced pilot workload and advanced engine health monitoring/diagnostics, assuring a high standard in aircraft dispatch availability. Special attention to “maintenance by design” enables fast access to engine externals and overnight, on-wing hot section refurbishment. The result is a compact, light weight design powering an impressive line of new generation very light business jets.
