Type Turbofan
National origin Canada
Manufacturer Pratt & Whitney Canada
Major applications Gulfstream G500/G600
Developed from Pratt & Whitney PW1000G

The Pratt & Whitney Canada PW800 is a turbofan engine in the 10,000 lbf (45 kN) thrust class. The engine is currently under development by Pratt & Whitney Canada. It was previously known by its company designation, the PW-10X. As of December 2009, the core of the engine has begun testing, despite having no announced application. On October 20, 2014 Gulfstream’s new G500/G600 choose to utilize this development engine. [1]

Development and design

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.[2] The PW800 was originally going to be a geared turbofan, like its larger sibling the PW1000G, but later announcements revealed that it was going to be a more traditional turbofan engine. However, the PW800 would still share a common core with the geared PW1000G.[3]

The PW800 core was to be the basis for the Pratt & Whitney Canada PW180 turboprop engine proposed for the Airbus A400M, however the Europrop TP400 was selected instead.[3]

In 2008 the PW810 variant was announced as the engine for the Cessna Citation Columbus business jet with an anticipated first flight of 2011.[4] However Cessna canceled the program in 2009, and with that cancellation, Pratt & Whitney announced a suspension in development for the PW800 engine.[5]

Despite this, Pratt & Whitney later announced that core testing was beginning before the end of 2009.[6] In December 2009, PWC announced that the core testing had begun.[7]

Few details about the design of the engine had been released by the end of 2009, but it had been announced that the high pressure spool of the engine would have eight compressor stages and two turbine stages.[6] Photos have been released revealing that the fan will have 20 wide-chord, metallic blades.[8] PWC has also revealed that the engine will feature a version of their Technology for Advanced Low NOx (TALON) combustor, which is designed to rapidly quench the combusted air to limit the production of Carbon monoxide (CO) by 35%. They also state that the engine should meet upcoming Stage IV noise requirements.[8]

MTU Aero Engines has a 15% share in the program, developing and producing the engine's high-pressure compressor and the low-pressure turbine.
