Beskrivelse

A great video of the Russian Military PAKFA stealth aircraft ready to boost Russian Military power. The Sukhoi Su-57 (Russian: Сухой Су-57)[14] is the designation intended for a stealth, single-seat, twin-engine jet multirole fighter aircraft designed for air superiority and attack operations.[15] The aircraft is the product of the PAK FA (Russian: ПАК ФА, Russian: Перспективный авиационный комплекс фронтовой авиации, Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii, literally "Prospective Aviation Complex of Frontline Aviation"), a fifth-generation fighter programme of the Russian Air Force. Sukhoi's internal name for the aircraft is T-50. The Su-57 will be the first aircraft in Russian military service to use stealth technology. The fighter is planned to have supercruise, stealth, supermaneuverability and advanced avionics to overcome the prior generation fighter aircraft as well as ground and maritime defences.[16][17]

The fighter is intended to succeed the MiG-29 and Su-27 in the Russian Air Force and serve as the basis for the Fifth Generation Fighter Aircraft (FGFA) being co-developed by Sukhoi and Hindustan Aeronautics Limited (HAL) for the Indian Air Force.[18][19] The prototype first flew on 29 January 2010 and deliveries of production aircraft to the Russian Air Force are to begin in 2018.[20] The prototypes and initial production batch are to be delivered with a highly upgraded variant of the AL-31F used by the Su-27 family as interim engines while a new clean-sheet design power-plant is currently under development. The aircraft is expected to have a service life of up to 35 years.[21]

Development[edit]
Origins[edit]
Main article: Post-PFI Soviet/Russian aircraft projects
In the late 1980s, the Soviet Union outlined a need for a next-generation aircraft intended to enter service in the 1990s. The project was designated the I-90 (Russian: Истребитель, Istrebitel, "Fighter") and required the fighter to have substantial ground attack capabilities and would eventually replace the MiG-29s and Su-27s in frontline tactical aviation service. The subsequent programme designed to meet these requirements, the MFI (Russian: МФИ, Russian: Многофункциональный фронтовой истребитель, Mnogofunksionalni Frontovoy Istrebitel, "Multifunctional Frontline Fighter"), resulted in Mikoyan's selection to develop the MiG 1.44.[22] Though not a participant in the MFI, Sukhoi started its own programme in the early 1990s to develop technologies for a next-generation fighter aircraft, resulting in the S-37, later designated Su-47. Due to a lack of funds after the collapse of the Soviet Union, the MiG 1.44 programme was repeatedly delayed and the first flight of the prototype did not occur until 2000, nine years behind schedule.[22] The MiG 1.44 was subsequently cancelled and a new programme for a next-generation fighter, PAK FA, was initiated. The programme requirements reflected the capabilities of Western fighter aircraft, such as the Eurofighter Typhoon and F-22 Raptor. Following a competition between Sukhoi, Mikoyan, and Yakovlev,[citation needed] in 2002, Sukhoi was selected as the winner of the PAK FA competition and selected to lead the design of the new aircraft.[23]

To reduce the PAK FA's developmental risk and spread out associated costs, as well as to bridge the gap between it and older previous generation fighters, some of its technology and features, such as propulsion and avionics, were implemented in the Sukhoi Su-35S fighter, an advanced variant of the Su-27.[24][25] The Novosibirsk Aircraft Production Association (NAPO) is manufacturing the new multi-role fighter at Komsomol'sk-on-Amur along with Komsomolsk-on-Amur Aircraft Production Association (KnAAPO), and final assembly is to take place at Komsomol'sk-on-Amur.[26][27] Following a competition held in 2003, the Tekhnokompleks Scientific and Production Center, Ramenskoye Instrument Building Design Bureau, the Tikhomirov Scientific Research Institute of Instrument Design (NIIP), the Ural Optical and Mechanical Plant (UOMZ) in Yekaterinburg, the Polet firm in Nizhny Novgorod and the Central Scientific Research Radio Engineering Institute in Moscow were selected for the development of the PAK-FA's avionics suite. NPO Saturn is the lead contractor for the interim engines; Saturn and MMPP Salyut will compete for the definitive second stage engines.[28]

On 8 August 2007, Russian Air Force Commander-in-Chief (CinC) Alexander Zelin was quoted by Russian news agencies that the programme's development stage was complete and construction of the first aircraft for flight testing would begin, and that by 2009 there would be three fifth-generation aircraft ready.[29][30] In 2009, the aircraft's design was officially approved.[23]
