Variants Sukhoi/HAL FGFA

The Sukhoi PAK FA (Russian: Perspektivnyi Aviatsionnyi Kompleks Frontovoi Aviatsy, Перспективный авиационный комплекс фронтовой авиации, or “prospective (promising) Aircraft System of Front line Aviation") is a fighter aircraft which is being developed by Sukhoi OKB for the Russian Air Force.

The current prototype is Sukhoi's T-50[5] and the PAK FA when fully developed is intended to replace the MiG-29 Fulcrum and Su-27 Flanker in the Russian inventory and serve as the basis of the Sukhoi/HAL FGFA project being developed with India.[6][7] A fifth generation jet fighter, it is designed to directly compete with the American F-22 Raptor and F-35 Lightning II. The T-50 is scheduled for its first flight in 2010.[8]

Development

Radar with APAA for the PAK FA is provided NIIP. MAKS-2009

In the late 1980s, the Soviet Union outlined a need for a next-generation aircraft to replace its MiG-29 and Su-27 in frontline service. Two projects were proposed to meet this need, the Sukhoi Su-47 and the Mikoyan Project 1.44. In 2002, Sukhoi was chosen to lead the design for the new combat aircraft. The PAK FA will incorporate technology from both the Su-47 and the MiG 1.44.

The Tekhnokompleks Scientific and Production Center, Ramenskoye Instrument Building Design Bureau, the Instrument Building Scientific Research Institute (Zhukovskiy), the Ural Optical and Mechanical Plant (Yekaterinburg), the Polet firm (Nizhniy Novgorod) and the Central Scientific Research Radio Engineering Institute (Moscow) were pronounced winners in the competition held in the beginning of 2003 for the development of the avionics suite for the fifth-generation airplane. NPO Saturn has been determined the lead executor for work on the engines for this airplane.

The Novosibirsk Chkalov Aviation Production Association (NAPO) has begun construction of the fifth-generation multirole fighter. This work is being performed at Komsomol'sk-on-Amur together with Komsomolsk-on-Amur Aircraft Production Association; the enterprise's general director, Fedor Zhdanov reported during a visit to NAPO by Novosibirsk Oblast's governor Viktor Tolokonskiy on 6 March 2007. "Final assembly will take place at Komsomol'sk-on-Amur, and we will be carrying out assembly of the fore body of this airplane," Zhdanov specified. The fifth-generation fighter, which will replace the MiG-29 and Su-27 airplanes of the previous generation, was developed by the Sukhoi design bureau.

NAPO Chkalov also has been realizing serial production of the newest Su-34 Fullback multirole bomber since last year. According to the governor, the oblast's government will adopt a complex of measures for supplemental governmental support to NAPO in the very near future. As of today, the most severe problem at the enterprise is personnel. "In the 1990s, many highly-qualified workers were let go under the conditions of a slump, and now time is needed for training new ones. Our assistance will be in the resolution of personnel questions, and also in the provision of lodging for the enterprise's specialists," governor Tolokonskiy said in this connection.

NAPO Chkalov is one of the country's largest airplane-building enterprises and is included in the Sukhoi Holding Company, ITAR-TASS notes.[9] On 8 August 2007, Russian Air Force Commander Alexander Zelin was quoted by Russian news agencies that the development stage of the PAK FA program is now complete and construction of the first aircraft for flight testing will now begin.[10]. Alexander Zelin also said that by 2009 there will be three (3) fifth-generation aircraft ready. "All of them are currently undergoing tests and are more or less ready", - he said. Though three prototypes were planned to have been produced by 2009 recent conferences and briefings have shown that no prototype had been produced by the original date disclosed by Zelin.[11]

Maiden flight

It was announced on 5 May 2007 by Deputy Prime Minister Sergei Ivanov that the first flight of the new aircraft was expected in late 2008, almost a year later than originally expected.[12] That estimate has now been superseded by the statement of Sukhoi CEO Mikhail Pogosyan, who stated at the Langkawi International Maritime and Aerospace (LIMA) 2007 exhibition in Malaysia on December 6 that the prototype will not fly until 2009.[13] This was again confirmed by the deputy prime minister in charge of arms procurement, Sergei Ivanov, in a news conference after a meeting of the Military-Industrial Commission in January 2009.[14]

On 28 of February 2009 Mikhail Pogosyan announced that the airframe for the aircraft was almost finished and that the first prototype should be ready by August 2009.[15] On 20 August 2009, Sukhoi General Director Mikhail Pogosyan said that the first flight would be by year end. Konstantin Makiyenko, deputy head of the Moscow-based Centre for Analysis of Strategies and Technologies said that "even with delays", the plane would likely make its first flight by January or February, adding that there could be at least 10 years between the first flight and commercial production.[16]

The Weekly Standard reports that Russian sources have indicated that the T-50 prototype will fly in 2010 or early 2011 with current technology radar, engines and avionics as the advanced systems for the completed PAK FA will require help from a foreign partner.[17] On December 8, 2009 The Deputy Prime Minister Sergei Ivanov announced that the first trials with the fifth generation aircraft would begin in 2010.[18]

Derivative project with India, The Sukhoi/HAL FGFA

Russia and India agreed in early 2007 to jointly study and develop a Fifth Generation Fighter Aircraft Programme, FGFA.[19][20] On October 27, 2007, Asia Times quoted Sukhoi's director, Mikhail Pogosyan, "We [India and Russia] will share the funding, engineering and intellectual property [of the new project] in a 50-50 proportion."[21] The Indian version, according to the deal, will be different from the Russian version and specific to Indian requirements[22]. While the Russian version will be a single-pilot fighter, the Indian variant will have a twin-seat configuration based on its operational doctrine which calls for greater radius of combat operations. The wings and control surfaces need to be reworked for the FGFA.[23] Although, development work has yet to begin, the Russian side has expressed optimism that a test article will be ready for its maiden flight by early 2010[24] induction into service by 2015.[25] Its Maiden Flight is said to be in early 2010.[26]

Design

Although there is no reliable information about the PAK FA's specifications yet, it is known from interviews with people in the Russian Air Force that it will be stealthy, have the ability to supercruise, be outfitted with the next generation of air-to-air, air-to-surface, and air-to-ship missiles, and incorporate a fix-mounted AESA radar with a 1,500-element array.[27] The PAK FA will use on its first flights 2 Saturn 117S engines (about 14.5 ton thrust each). The 117S is an advanced version of the AL-31F, but built with the experience gained in the AL-41F program. The AL-41F powered the Mikoyan MFI fighter (Project/Article 1.44). Later versions of the PAK FA will use a completely new engine (17.5 ton thrust each), developed by NPO Saturn or FGUP MMPP Salyut.

On 20 August 2009, Russian Air Force Chief Alexander Zelin said that there were problems with the engines and research was continuing.[28]
