Pratt & Whitney Canada PW600

Pratt & Whitney Canada PW600

The PW600 family of extremely small turbofan engines is being developed by Pratt & Whitney Canada for use in very light jets. Designed with scalability in mind, the engines can produce between convert|900|lbf|abbr=on and convert|3000|lbf|abbr=on of take-off thrust.

First run of the convert|2500|lbf|abbr=on thrust PW625F demonstrator engine was on October 31, 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 PW610F's, 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 2.8. Driven by a single-stage LP turbine, the single stage fan is an advanced snubberless design, with wide chord blades integral with the rotor hub. The newly patented 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, for smoother, more reliable, operation, is included in the specification. Hispano-Suiza Canada is currently designing and manufacturing the Full Authority Digital Electronic Control (FADEC) for this engine.

The larger, convert|1350|lbf|abbr=on 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 convert|1200|lbf|abbr=on thrust.

So far, the convert|1615|lbf|abbr=on thrust PW617F, with a 17.6 inch (44.7 cm) diameter fan, is the largest in the family and is to power the forthcoming 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.

As of October 15, 2006, fifty PW610F's and PW615F's had been delivered by P&WC.
