Brazil join Russia on PAK-FA Program




Posted on: Thursday, 17 April 2008, 12:00 CDT



Brazil, Russia Sign Agreement on Fighter Jets, Space Launch Vehicles


Brazil is going to participate in the programme to develop an advanced combat plane, the PAK-FA T-50, that will be built by the Russian Sukhoi firm. The aircraft, invisible to radar, promises to equal or exceed in performance the F-22 Raptor fighter produced in the United States (the most expensive in the world at a unit cost of 225m dollars) and should make its first flight within two years at most.

Construction of the new aircraft is only part of a wide-ranging memorandum of understanding negotiated in Moscow in February and signed yesterday by Minister of Strategic Affairs Mangabeira Unger and the secretary of the Security Council of the Russian Federation, Valentin Alekseevitch. The framework agreement marks the start of extensive cooperation between the two countries, including that on technologies considered sensitive. Called for in the space field is construction of a new launch vehicle for communication and remote sensing satellites. Use of he Alcantara Airspace Base by a new binational firm is also contemplated in the treaty.

While discussing the PAK-FA, Mangabeira emphasized that it would be a fifth-generation fighter. Total cost is estimated at about 20bn dollars to be divided among Russia, Brazil, and India, which will also participate in the programme. The unit price, lower than that of fourth-generation European fighters, will be approximately 80m dollars.

In addition to being invisible to radar, the fifth-generation combat planes will be capable of reaching supersonic speed using half the engines power, a capability that reduces fuel expense, increases range, and reduces enemy engagement time. Currently, only the Americans have aircraft with those characteristics - the F-22 Raptors - in operation. A cheaper model, the F-35 Lightning, which costs 135m dollars, is in the certification phase. Minister of Defence Nelson Jobim was able to watch a demonstration of that fighter during his visit to the United States, but the aircraft was ruled out because no technology transfer was offered with it.

We are interested not in buying finished goods but in partnerships that can strengthen the technological capability of both, the minister said. Besides Russia, China and Japan are also working on fifth-generation aircraft, but the PAK-FA project, which began 10 years ago, is the one currently at the most advanced stage.

Satellite Launch Vehicle

Russia is already cooperating with Brazil in the space field. A group of experts is in Sao Jose dos Campos acting as advisers on the Satellite Launch Vehicle (VLS) programme. The Russians are participating in the design of a new first stage, using liquid rather than solid fuel, for the rocket, which has accumulated a series of failures since the first launch attempt in 1997. Our country also has technology transfer programmes with Ukraine in connection with the production of rockets and with France, which intends to produce medium-size helicopters in Minas Gerais and submarines in Rio de Janeiro.

JF-17 GOES STEALTHY




05/02/2008 - TEMPUR FEBRUARY 2008







In what is seen as a counter to India effort to jointly develop the Fifth Generation Fighter Aircraft (FGFA) with Russia Sukhoi Aircraft Corp, Pakistan Kamra-based Pakistan Aeronautical Complex (PAC) and China Chengdu Aerospace Corp (CAC) last October inked a Memorandum of Understanding (MoU) to jointly develop an advanced, stealthy, single-seat and single-engined derivative of the JF-17 Thunder fourth-generation light multi-role combat aircraft (MRCA) that is already being co-developed by PAC and CAC. Consequently, the Pakistan Air Force (PAF) is expected to induct only 100 JF-17s into service between this year and 2014, and subsequently switch over to the acquisition of another 150 JF-17-derived fifth-generation stealthy MRCAs between 2015 and 2025. Present plans call for the latter MRCA to be powered by SNECMA Moteurs M88-3 twin-shaft bypass turbofan, incorporate a digital glass cockpit and open-architecture avionics suite, and use SELEX Sensors and Airborne Systems Vixen 500E X-band multi-mode active phased-array radar, or AESA, an integrated electronic warfare/defensive aids suite being developed by China CETC, along with a helmet-mounted sighting-cum-cueing system for which systems from THALES, BAE Systems and Denel Aerospace are being evaluated. The M88 turbofan for this aircraft will have variable camber inlet guide vanes, while its high-pressure compressor will have a sixth stage, and its exhaust nozzle will be of the ejector type. The turbofan will deliver 50kN (11,250lb) of dry thrust and 75kN (17,000lb) with afterburning. The primary offensive armament to be carried by this aircraft will be two underwing-mounted Hatf-8 (also called Raad or Thunder in Arabic) air-launched cruise missile, which has a range of 350km. For air combat engagements, the stealthy MRCA will be armed with three types of air-to-air missiles: 60km-range PL-12 beyond visual range missile; 15km-range PL-13 within visual range missile; and PL-14 ramjet-powered 100km-range missile. The latter two have been developed by China in cooperation with South Africa Denel Aerospace.
In contrast, the JF-17, which is due to enter service late next year, is a light MRCA that will be eventually replace the PAF existing CAC-built F-7P Skybolt and F-7MG light MRCAs...

Reality Check




27/05/08 - TEMPUR MAY 2008







The delayed delivery of the aircraft carrier INS Vikramaditya (estimated by 2012), and the R & D slippages of two futuristic programmes the fifth-generation fighter aircraft (FGFA) and the multi-role transport aircraft (MTA) ll have one thing in common: the delays are being caused by an acute shortage of trained technical manpower that currently prevails throughout the Russian Federation. For Moscow has since mid-2007 decided to focus the majority of its scarce human resources firstly towards the creation of new-generation strategic weapon systems, and secondly towards the creation of new military-industrial facilities within Russia that will enable Russia to forever eliminate its current dependence on existing manufacturing facilities located in Belarus, Georgia, Kazakhstan and Ukraine. Russia believes that such dependency has, since the early 1990s, robbed it of tens of billions of dollars in terms of revenues earned from exports of weapon systems whose intellectual property rights are those of Russia. The implications for India of such measures adopted by Moscow are obvious: the United Aerospace Corp (UAC) hich now includes Sukhoi Aircraft Corp and RAC-MiG long with the Tsentralniy Aerogidrodinamicheskiy Institut (Central Aerohydrodynamic Institute), has now dropped the idea of co-developing with India state-owned Defence Research & Development Organisation (DRDO) and Hindustan Aeronautics Ltd (HAL) the twin-engined 17.2-tonne FGFA (for the air forces of India and Russia), which in Russia is known as the Mnogofunktsyonalniy Frontovoy Samolyot (MFS) project, and is instead developing the heavier, 24-tonne T-50 Perspektivnyi Aviatsionnyi Kompleks Frontovoi Aviatsyi (PAK-FA) advanced tactical frontline fighter. Consequently, the FGFA Russian R & D effort will henceforth be funded by private institutions, will be co-developed only for export and all Russian R & D contributions will henceforth be reduced by 85% and the void will be filled up by HAL and Embraer of Brazil, both of which inked collaborative deals to this effect with Rosoboronexport State Corp on April 15. Efforts are now underway to rope in South Africa Denel Aerospace as the fourth risk-sharing R & D partner. As for the MTA project, whose R & D effort was to be shared equitably by IRKUT Corp, Sukhoi Aircraft Corp and HAL, it last month underwent a complete makeover when the two Russian companies withdrew their participation. Instead, efforts are now underway to formalise a multinational consortium that will include Russia Ilyushin Finance Corp, HAL, Embraer, South Africa Denel Saab Aerostructures, and Sweden Saab AB.

It may be recalled that on May 18, 2003 the FGFA engineering development-cum-production effort officially took off after an agreement to this effect was inked by the Russian Aerospace Agency Rosaviakosmos, Sukhoi OKB, the Sukhoi Military Production Complex, NPO Saturn, Vympel, Zvezda-Strela, TsAGI research institute, Aerospace Equipment Corp, Ramenskoye RPKB, Polet, Tekhnocomplex, Tikhomirov NIIP, Urals Optics Mechanical plant, KNIIRTI, UMPO of Ufa, Gromov Flight Test and Research Institute in Zhukovsky, and MMPP Salyut of Moscow. The Russian R & D masterplan then called for the FGFA to make its maiden flight in 2009, construction of seven flying prototypes, commencement of series production by 2011 and service entry a year later, thus making it available for export at around the same time the Lockheed Martin-built F-35 Joint Strike Fighter is due to enter service. In early 2005 when Sukhoi OKB gave its first generic presentation on the FGFA to IAF HQ, it was quite surprised to hear that the IAF wanted a twin-engined, 17.2-tonne aircraft that was at least 5 tonnes lighter than the PAK-FA...

5th generation fighter aircraft will fly in march next: Adviser




Bangalore, June 14: The country's 'ambitious' fifth generation fighter aircraft will fly during March next, the information to this effect was given by M Natarajan, Scientific Advisor to Defence Minister on Saturday.

Efforts were on to identify a Russian company to provide weapons and electronic warfare systems, Natarajan, who is also the secretary, Defence Research and Development Organisation, said while participating in the inauguration of the Defence avionics research establishment's new campus here.

Conceptualisation studies have begun on Medium Combat Aircraft (MCA) he said.

"We are in the process of evolving a design for MCA", Natarajan said.

LCA has great potential notwithstanding problems, he said and added they were being attended to.

DRDO director R P Ramalingam, in his welcome address, said it would be Field-testing the fourth generation electronic warfare systems in about 18 months for Mig 27 and LCA.

There was also a possibility of extending the tests to fifth generation fighter aircraft, he said.

PAK-FA Engine




MAKS-2007








2 Saturn-Lyulka AL-41F turbofan (NPO Saturn AL-41F)



The NPO Saturn AL-41F is a Russian turbofan engine, designed for supercruise flight. Originally developed for the Mikoyan Project 1.44, the engine was built around the geometry of the AL-31F, making it compatible with existing airframes, including the Sukhoi Su-27 series. The engine is reported to have recently entered low rate initial production for use in the Su-34 Fullback. Specifications are not disclosed yet, but it is described by most sources as being in the 40.000 lbf class, 10:1 thrust to weight ratio.

A heavily-upgraded version of the Al-31F is being developed for the Su-35BM prototype and possibly to power the early flights of PAK-FA. This engine has been named the AL-41F1A. It is important to note that the AL-41F1A is not considered a part of the same AL-41 line as was planned for the Mikoyan Project 1.44 because it uses the core of the AL-31F, whereas the AL-41F utilizes an entirely new core. The designation appears to be present because the engine approaches the projected specifications of the new AL-41F class. The engine is specified as being able to provide 14.5 tons of thrust. It is also notable that the engine is capable of mounting 3D Thrust Vectoring Nozzles for extra maneuverability.

Russian plasma stealth fighters



First developed by the Russians, plasma stealth technology is also known as active Stealth Technology. Plasma stealth is a proposed process that uses ionized gas (plasma) to reduce the radar cross section (RCS) of an aircraft. A plasma stream is injected in front of the aircraft covering the entire body of the aircraft and absorbing most of the electromagnetic energy of the radar waves, thus making the aircraft difficult to detect.

There are few experimental studies of plasma effect on RCS. One of the most interesting articles was published by the Institute of Electrical and Electronics Engineers (IEEE) in 1963 and described the effect of plasma on the RCS of aircraft. The article entitled radar cross sections of dielectric or plasma coated conducting spheres and circular cylinders was based on the data offered by Sputnik, the first artificial satellite launched by the Soviet Union on October 4, 1957.

While trying to track Sputnik it was noticed that its electromagnetic scattering properties were different from what was expected for a conductive sphere. This was due to the satellite traveling inside of a plasma shell.While Sputnik was flying at high velocity through the ionosphere it was surrounded by a naturally-occuring plasma shell and because of it there were two separate radar reflections: the first from the surface of the satellite itself and the second from the plasma shell. If one of the reflections is greater the other one will not contribute much to the overall effect. When the two reflections have the same order of magnitude and are out of phase relative to each other cancellation occurs and the RCS becomes null. The aircraft becomes invisible to radar.

In January 1999, the Russian news agency ITAR-TASS published an interview with Doctor Anatoliy Koroteyev who talked about the plasma stealth device developed by his organization. Doctor Koroteyev was the director of the Keldysh Research Center. There have also been claims that in 2002 the Russians tested a plasma stealth device on board a Su-27 and RCS was reduced by a factor of 100.

The Keldysh Research Center has created a plasma generator that weights no more than 100 kilos, thus making it possible to be fitted on board most tactical aircraft. Current stealth technology uses radar absorbent materials (RAM) and angled surfaces that dont reflect radar waves back. This constitutes as a main drawback, since an alteration of the airframe has negative effects on the flight characteristics of these aircraft. The third generation stealth technology F-22 Raptor seems however to be an exception since it is both a fast aicraft and very maneuverable.

By using a plasma generator the aerodynamic characteristics of the aircraft do not suffer which in term means that the payload is increased making it more effective. The use of this technology offers the benefit of not having to carry the payload internally to be able to fool enemy radar. The Sukhoi Su-35 and the MiG-35 (both upgrades of Su-27 and MiG-29) are the first to benefit from this technology.

One of the most interesting russian fighters to benefit from the plasma stealth technology is the MiG 1.42/1.44 also known as the MFI (Mnogofunktsionalny Frontovoi Istrebitel - Multifunctional Frontline Fighter). This new aircraft is a fifth generation air-superiority fighter, a rival for the american F-22 Raptor. Both aircraft have the same supercruise capability as well as thrust vectoring for supermaneuverability (a capability to fly at supercritical angles of attack, at increased level of sustained and
available g-loads and high turn-angle rate, which require a greater thrust-to-weight ratio and improved wing aerodynamic efficiency). This aircraft may prove to be a milestone in aviation, as so many russian aircraft were before.

Teknologi stealth itu mengliputi banyak segi. Bukan sahaja susah dikesan oleh radar, tapi teknologi kesan haba (Infra-red)  rendah, dan juga dari segi bunyi enjin rendah. Jadi yang membuat pesawat itu stealth mengliputi banyak bahagian. Untuk membuat pesawat itu rumit dikesan radar, pesawat itu dibuat oleh bahan komposit yang 'memakan' tenaga radar (Radar-absorbent material), design engine pun memasuk angin sejuk sebelum keluar dari exhaust, akibatnya haba dan kepanasan engine pun rendah. Ini antara teknologi yang membuat harga pesawat stealth itu sangat mahal.

Russia, India to sign next-generation fighter deal in early 2009




by Staff Writers


New Delhi, India (RIA Novosti) Dec 09, 2008



Russia and India are due to sign a contract at the beginning of 2009 to jointly develop and produce a fifth-generation jet fighter, the head of the United Aircraft Corporation said on Friday.

"We are planning to conclude the contract at the beginning of next year," Alexei Fedorov said.
The Russian-Indian advanced multirole fighter is being developed by Sukhoi, which is part of Russia's United Aircraft Corporation (UAC), along with India's Hindustan Aeronautics Limited (HAL), under a preliminary intergovernmental agreement signed in October 2007.
Russia and India will simultaneously develop two versions of the combat aircraft - a two-seat version to meet the requirements of India's air superiority policy, and a single-seat version for the Russian Air Force.
Russia's Sukhoi aircraft maker earlier said it had started to construct a prototype of the fifth-generation fighter, which will feature high maneuverability and stealth to ensure air superiority and precision in destroying ground and sea targets.
The Russian version will be built at the Komsomolsk-on-Amur aircraft-manufacturing plant in Russia's Far East.
Flight tests of the fighter are due to begin as early as 2009, and the aircraft may go into production by 2015, Sukhoi said. Russia's military cooperation with India goes back nearly half a century, and the Asian country accounts for about 40% of Russian arms exports
