The '''Aviadvigatel PS-90''' is a Russian [[Bypass ratio|high-bypass]] commercial [[turbofan]] rated at 16000 [[kilogram-force|kgf]] (157 [[kilonewton|kN]], 35,300 [[pound-force|lbf]]) thrust. It powers Russian airliners such as the [[Ilyushin Il-96]] and the [[Tupolev Tu-204|Tupolev Tu-204/Tu-214]] series and transport aircraft such as the [[Ilyushin Il-76]]. It is made by the Russian [[aircraft engine]] company [[Aviadvigatel]], which is the successor of the [[Soviet Union|Soviet]] [[Soloviev Design Bureau]]. "PS" are the initials of [[Pavel Soloviev]] ({{langx|ru|'''П'''áвел Алексáндрович '''С'''оловьёв}}).

==Design and development==
With the advent of new generation of Soviet airliners, [[Aviadvigatel]] developed the PS-90 to satisfy the demands of economy, performance and exhaust emissions. It represented a huge advance over previous generations of 1960s era Soviet engines. The PS-90 is almost double the efficiency of those engines and is reasonably competitive to western engines of the 1980s such as the [[PW2000|Pratt & Whitney PW2000]].

===Design features===
[[File:Air Koryo Tupolev aircraft.jpg|thumb|An [[Air Koryo]] Tu-204-300]]
It incorporates many firsts in a one-of-a-kind Russian engine with advanced technology features such as
*High-bypass turbofan design for economy
*Integrated exhaust with [[exhaust mixer]] for good efficiency
*Acoustically treated exhaust duct for low noise
*Full-authority digital engine control ([[FADEC]])
*Long service life based on on-condition maintenance
*Modular design for ease of maintenance

It was first certified in 1992 and has been in service since.

==Variants==
There are several variants: the basic PS-90A, the PS-90A-76, and the improved PS-90A versions. The latter include the PS-90A1, PS-90A2, PS-90A-42 and the PS-90A3 engines.

===PS-90A===
[[File:PS-90A engine on MAKS-2021 airshow.jpg|thumb|right|PS-90A on [[MAKS (air show)|MAKS-2021]]]]
The PS-90A engine is the initial variant and is standard equipment for [[Il-96|Ilyushin Il-96-300]], [[Tupolev Tu-204|Tupolev Tu-204-100]] and [[Tupolev Tu-204|Tupolev Tu-214]]. For the first time, it allowed Russian airliners to achieve similar performance and economy to their western counterparts. PS-90A is rated nominally at 16000 kgf (157&nbsp;kN, 35,300&nbsp;lbf) thrust, 13.3% less than the [[Rolls-Royce RB211|Rolls-Royce RB211-535]]E4 engine (which is also offered on the Tu-204), and the fuel consumption is 8.2% less than it.<ref>{{Cite web|url=http://www.avid.ru/en/avia/?id=1/|title=PS-90А Aero Engine|website=www.avid.ru|language=en|archive-url=https://web.archive.org/web/20170909045224/http://www.avid.ru/en/avia/?id=1|archive-date=2017-09-09|url-status=|access-date=2018-05-19}}</ref>

===PS-90A-76===
[[File:Ilyushin Il-76TD-90 (Silk Way) (8738163541).jpg|thumb|A pair of PS-90A-76 engines on the Il-76.]]
This variant is a modification of the basic PS-90A engine. It is rated nominally up to  14,500 kgf (142&nbsp;kN, 32,000&nbsp;lbf) take-off thrust.<ref>{{Cite web|url=http://www.avid.ru/en/avia/?id=2|title=PS-90А-76 Aero Engine|website=www.avid.ru|language=en|archive-url=https://web.archive.org/web/20170909045240/http://www.avid.ru/en/avia/?id=2|archive-date=2017-09-09|url-status=live|access-date=2018-05-19}}</ref>

By replacing the [[Soloviev D-30|D-30KP]] on the older [[Il-76]], the service life of the aircraft can be extended. [[Fuel efficiency]], and performance will be markedly improved and noise pollution reduced to comply with the new strict requirements.  With the large fleet of both civil and military [[Il-76]] aircraft still in operation, a potentially large market exists for engine replacement. An example of such a modified version is the [[Il-76|Il-76MD-90]]. The [[PS-90A|PS-90A-76]] is the standard on the newly built, modernized versions of the [[Il-76]], such as the [[Il-76|Il-76MD-90A]] and the [[Il-76|Il-76MF]].

===PS-90A1===
This variant is also a modification of the basic PS-90A engine. It was certified in 2007 and is offered as an option on the [[Il-96|IL-96-400T]] aircraft.<ref>{{Cite web|url=http://www.avid.ru/en/avia/?id=3/|title=PS-90А1 Aero Engine|website=www.avid.ru|language=en|archive-url=https://web.archive.org/web/20170909045347/http://www.avid.ru/en/avia/?id=3|archive-date=2017-09-09|url-status=live|access-date=2018-05-19}}</ref>

===PS-90A2===
The PS-90A2 is an advanced derivative of the PS-90A, developed in cooperation with [[Pratt & Whitney]].<ref>{{Cite web|url=http://www.avid.ru/eng/pr/news/654/|title=Top Managers of Pratt & Whitney and Perm Motors Group Companies Discussed PS-90A2 Aero-Engine Development Program|date=2007-11-15|website=avid.ru|archive-url=https://web.archive.org/web/20141006163752/http://avid.ru/eng/pr/news/654/|archive-date=2014-10-06|url-status=}}</ref> It has a fair proportion of western components from France, Germany, Sweden and the USA. It is also lighter than PS-90A and features improved [[FADEC]]. These features improve the performance and reduce maintenance costs by 40%. Fuel consumption is on par with current western engines{{Citation needed|date=October 2014}}, and its noise levels are below the current regulatory requirements. The PS-90A2 is the first Russian engine to be [[ETOPS]]-180 min rated. It is offered in newly built aircraft and is completely interchangeable with the PS-90A, allowing simple upgrades on present airliners.

It has the same thrust rating as the PS-90A, 16000 kgf (157&nbsp;kN, 35,300&nbsp;lbf) thrust. It is also capable of 18000 kgf (176&nbsp;kN, 39,600&nbsp;lbf) thrust.<ref>{{Cite web|url=http://www.avid.ru/en/avia/?id=4/|title=PS-90А2 Aero Engine|website=www.avid.ru|language=en|archive-url=https://web.archive.org/web/20170909045229/http://www.avid.ru/en/avia/?id=4|archive-date=2017-09-09|url-status=live|access-date=2018-05-19}}</ref>

Future American involvement in engine development has been put in doubt after attempts to block sale of PS-90A2 engines to an Iranian customer.<ref>{{cite web|url=http://www.rbcdaily.ru/2010/04/15/industry/471843 |title=Американские санкции приземлили Ту-204СМ :: Статьи :: РБК daily |accessdate=2010-11-13 |url-status=dead |archiveurl=https://web.archive.org/web/20110724113457/http://www.rbcdaily.ru/2010/04/15/industry/471843 |archivedate=2011-07-24 }}</ref>

===PS-90A-42===
This is a version of the PS-90A2 intended for the [[Beriev A-40|Beriev A-42]] search and rescue aircraft.<ref>{{Cite web|url=http://www.pmz.ru/eng/advanced-developments/PS-90A-42/|title=PS-90A-42 turbojet aero-engine}}</ref>

===PS-90A3===
According to the manufacturer, it is a modification of the PS-90A2. It was certified in January 2011 and intended to power the [[Tupolev]] [[Tu-204|Tu-204SM]] aircraft.<ref>{{Cite web|url=http://www.avid.ru/eng/pr/news/1111/|title=PS-90A3 Engine flight-ready!|date=2011-01-28|website=avid.ru|archive-url=https://web.archive.org/web/20140809223409/http://www.avid.ru/eng/pr/news/1111/|archive-date=2014-08-09|url-status=}}</ref><ref>{{Cite web|url=http://www.airliners.net/aviation-forums/general_aviation/read.main/6137187/|title = Airliners.net - Aviation Forums}}</ref> It is unclear whether the US and European components of the PS-90A2 remain or whether they have been replaced by Russian ones.<ref>{{Cite web|url=http://www.airliners.net/aviation-forums/general_aviation/read.main/6137187/|title = Airliners.net - Aviation Forums}}</ref> If the US components have indeed been replaced, then this engine could be fitted to the [[Tu-204|Tu-204SM]] ordered by [[Iran Air]] and its subsidiaries.
