Pratt & Whitney Canada PW600 - Design and Development

Design and Development

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.

As of October 15, 2006, fifty PW610Fs and PW615Fs had been delivered by P&WC.

Famous quotes containing the words design and/or development:

    I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.
    John Adams (1735–1826)

    On fields all drenched with blood he made his record in war, abstained from lawless violence when left on the plantation, and received his freedom in peace with moderation. But he holds in this Republic the position of an alien race among a people impatient of a rival. And in the eyes of some it seems that no valor redeems him, no social advancement nor individual development wipes off the ban which clings to him.
    Frances Ellen Watkins Harper (1825–1911)
