The Pratt & Whitney Canada PW800 is a turbofan engine in the 10,000–20,000 lbf (44–89 kN) thrust class, under development by Pratt & Whitney Canada. Intended for the regional jet and business jet market, the gear-less PW800 share a common core with the larger, geared PW1000G. The first variants were certificated on February 15, 2015 to power the new Gulfstream G500/G600.
Design and 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.[1] After the Advanced Technology Fan Integrator demonstrator first run on March 17, 2001, Which became the PW1000G, Pratt & Whitney Canada was searching for a launch customer for the initially geared PW800, in the 10,000–19,000 lbf (44–85 kN) thrust range, bridging the gap between P&WC's PW300 and P&W's PW6000, intended for the regional- and business-jet engine market.[2]
The PW800 core was to be the basis for the Pratt & Whitney Canada PW180 turboprop engine proposed for the Airbus A400M.[3] However the Europrop TP400 was selected instead.[4]
Pratt & Whitney Canada showcased at the 2007 Paris Air Show its PW-10X engine development, within the 10,000-pound-thrust-class among the Rolls-Royce RB282, General Electric CF34 successor which became the General Electric Passport, Snecma Silvercrest and Honeywell pushing its HTF10000 development of the HTF7000.[5] The PW800 was originally going to be a geared turbofan like the PW1000G.[6] Later announcements revealed that it wasn't going to feature a reduction gear.[7]
In 2008, the PW810 variant was announced as the engine for the Cessna Citation Columbus business jet with an anticipated first flight of 2011.[8] However Cessna canceled the program in 2009, which halted the PW810 program, but Pratt & Whitney continued the PW800 series development.[9]
Pratt & Whitney later announced that core testing was beginning before the end of 2009. 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.[10] In December 2009, PWC announced that the core testing had begun.[11] It made its first run in April 2012 and first flew in April 2013.[12]
On October 20, 2014, the engine was selected by Gulfstream for its new Gulfstream G500/G600.[13] Pratt & Whitney Canada (P&WC) announced on February 17, 2015 that it had received Transport Canada type certification for its PW814GA and PW815GA engines, which will power the new Gulfstream G500 (5,000 nmi range) and G600 (6,200 nmi range) business jets, respectively.[14] On May 18, 2015, the Gulfstream G500 took its first flight using the PW814A engine. So far, the PW800 engine family has surpassed 3,600 hours of full engine testing, including rigorous endurance testing that simulates a multitude of aircraft missions and environments, and more than 470 hours on P&WC's 747 Flying Test Bed.[15]
The engine will feature the Technology for Advanced Low NOx (TALON) X combustor, allowing it to exceed International Civil Aviation Organization (ICAO) standards for NOx by 50%, Carbon monoxide (CO) by 35% and that the engine should meet upcoming stage IV aircraft noise requirements.[16] A previous version of the TALON combustor is in service with the Pratt & Whitney PW4000.
MTU Aero Engines has a 15% share in the program, developing and producing various stage of the high-pressure compressor and the low-pressure turbine.[17]
