The '''Pratt & Whitney Canada PW800''' is a series of turbofan engines in the {{convert|10,000|-|20,000|lbf|kN|abbr=on}} thrust class, manufactured by Pratt & Whitney Canada. Intended for the regional jet and business jet market, the gear-less PW800 shares a common core with the larger, geared PW1000G. The first variants were certified on February 15, 2015, to power the new Gulfstream G500/G600. A later variant was certified in 2021 for the Dassault Falcon 6X.

== 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.<ref>{{cite news |author= Guy Norris |url= http://aviationweek.com/awin/five-engine-companies-chase-same-bizjet-market-changes-are-underway |title= Five Engine Companies Chase The Same Bizjet Market, But Changes Are Underway |journal= Aviation Week & Space Technology |date= 6 Oct 2008}}{{subscription required}}</ref> After the Advanced Technology Fan Integrator demonstrator first ran on March 17, 2001, which became the PW1000G, Pratt & Whitney Canada was searching for a launch customer for the initially geared PW800, in the {{convert|10,000|-|19,000|lbf|kN|abbr=on}} thrust range, bridging the gap between P&WC's PW300 and P&W's PW6000, intended for the regional- and business-jet engine market.<ref>{{cite news |url= https://www.flightglobal.com/news/articles/pratt-whitney-canadas-geared-turbofan-seeks-launc-128579/ |title= Pratt & Whitney Canada's geared turbofan seeks launch customer |work= Flight Global |date= 10 April 2001}}</ref>

The PW800 core was to be the basis for the Pratt & Whitney Canada '''PW180''', a {{convert|12000|hp|kW|adj=pre|shaft|abbr=off}} turboprop engine proposed for the Airbus A400M Atlas.<ref>{{cite magazine |title=Profit margins in A400M engine program will be thin, official says |date=8 May 2003 |page=5 |magazine=Aerospace Daily |volume=206 |number=28 |given1=John |surname1=Fricker |given2=Rich |surname2=Tuttle |issn=0193-4546}}</ref> However the Europrop TP400 was selected instead.<ref>{{cite news |url= https://www.flightglobal.com/news/articles/usa-blasts-a400m-engine-choice-165396/ |title= USA blasts A400M engine choice |work= Flight International |date= 13 May 2003}}</ref>

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.<ref>{{cite news |url= http://www.ainonline.com/aviation-news/business-aviation/2007-06-19/pwc-going-green-pw-10x |title= PWC is going green on PW-10X |author= Julian Moxon |date= June 19, 2007 |work= Aviation International News}}</ref>

== Design ==

The PW800 was originally going to be a geared turbofan like the PW1000G.<ref>{{cite news |url= http://www.ainonline.com/aviation-news/2007-10-16/two-new-contenders-vie-power-future-rjs |title= Two new contenders vie to power future RJs |author= Thierry Dubois |date= October 16, 2007 |work= Aviation International News}}</ref> While the PW814/PW815 shares the core of the PW1500G (powering the Airbus A220) and the PW812D shares the core of the PW1200G (powering the Mitsubishi MRJ),<ref name=Flight20may2019/> neither model ultimately incorporated the reduction gear system.<ref name="janes">{{cite news |title= P&WC PW800 |work= Jane's Aero Engines |date= 13 Oct 2009}}</ref>

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.<ref>{{cite news |url= http://airinsight.com/2016/05/23/pwcs-pw800-leading-next-generation-business-aircraft-engine-market/ |title= Leading the next-generation business aircraft engine market |date= May 23, 2016 |publisher= Air Insight}}</ref> 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.<ref>{{cite web |url= http://www.mtu.de/engines/commercial-aircraft-engines/business-jets/pw800/ |title= PW800 |publisher= MTU Aero Engines }}</ref>
