Sukhoi PAK-FA / FGFA: Updates,News & Discussions

Why does it need a bump to divert airflow? Does the innards of the intake design necessitate it?

Flankers did not have such bumps, right?

To improve the engine performance I guess, similar to the effect of DSI I guess, the Flankers had a straight intake, this one is shaped with curves, be it this bump on the one side, or the one behind the gear bay on the other side.

Additionally I think they help to shield the fan blades.

It's done to prevent the formation of turbolent air flow before compressor blades at very high AOA.
Or simply,to prevent compressor stall at very high AOA.

5th-Gen fighter plan hits hurdle as Russia hikes cost

NEW DELHI: India's biggest defence project in the making, the critical joint development of the fifth-generation fighter aircraft (FGFA) with Russia, has flown into some rough weather.

Defence ministry sources said the inking of the final design and R&D contract for the stealth fighter has been hit by a huge delay, with Russia also jacking up costs for the futuristic project. "It's very unlikely the FGFA final design contract will be concluded in the 2013-2014 fiscal," said a source.

This contract was to be inked in 2012 as per the then revised timeline after completion of the preliminary design contract (PD C) phase. India will eventually end up spending close to $35 billion over the next two decades to induct over 200 such "swing-role" fighters.

The plan till last year was that India would begin inducting the FGFA from 2022 onwards, with IAF test pilots getting three prototypes in 2014, 2017 and 2019 for trials at the Hindustan Aeronautics manufacturing facility at Ozar.

"The timeframes will now have to be revised. MoD has established a committee of specialists and finance officials to verify the rise in costs. An internal contract negotiation committee is also in progress," said the source.

But India remains firm about rejecting the US offer for joining its Joint Strike Fighter (JSF) or the F-35 'Lightning-II' programme. "A lot of money and time has been invested in the FGFA with Russia. India simply cannot afford two FGFAs, both financially as well as logistically" he said.

The 18-month PDC worth $295 million for the FGFA with Russia was inked in December 2010, under which Indian designers and scientists have even been stationed in Russia to work out the blueprints and documentation for the fighter.

Though the Indian "perspective multi-role fighter" will be based on the Russian single-seat FGFA called Sukhoi T-50 or PAK-FA, which now has four prototypes flying, it will be tweaked to IAF requirements. IAF had initially pitched for 166 single-seat and 48 twin-seat fighters but will go for only single-cockpit jets now to reduce costs as well as protect stealth features.

The final design contract now being negotiated was pegged at $11 billion, with India and Russia sharing $5.5 billion each towards the cost of designing, infrastructure build-up at Ozar, prototype development and flight testing. Each fighter was to cost over $100 million.

IAF is quite confident the T-50 will meet its future requirements. Apart from ultra-manoeuvrability and supersonic cruising ability, the FGFA will carry its weapons inside the fuselage to lower its radar signature. With a cruising speed of Mach 1.7 to 1.8, it has both long-range strike and high-endurance air defence capabilities.

IAF is currently making do with just 34 fighter squadrons (each has 14 to 18 jets) despite needing at least 44 to keep both Pakistan and China at bay. It's banking upon the ongoing induction of 270 Russian Sukhoi-30MKIs for around $12 billion as well as the early inking of the almost $20 billion project to acquire 126 French Rafale fighters to plug operational gaps till the FGFA becomes a reality.

Cost overruns are typical of 5th generation fighters, no surprise there.

PAK FA will get "unlimited" oxygen system

A promising Russian fighter jet the T-50 (the PAK the FA) will get a a new system of filing of oxygen in the a respiratory mask the pilot. How to writes the newspaper "Izvestia», a system of has developed a scientifically-and-Production enterprise «Star of». Such equipment allows you to to get the oxygen for the respiratory a mixture of right out of the of air during of the flight. For comparison, the all facing on arms of Air Force Russian fighter jets are equipped with the oxygen bomb a limited of volume.

In the words of the chief specialist of Scientific and production enterprise «Star of» of Mikhail Dudnik, thanks to the new of the oxygen system the time of flight at an altitude of now will not be depend from the stock of oxygen in cylinders. In addition, the-board system for allows to save on a payload of: the mass of of a new the equipment makes of only 30 of kilograms, in the then the time of as a system of of oxygen cylinders by two hours of flight weighs about 90 kilograms.

Development of the system of generation of oxygen was conducted throughout the five of recent years. At the present time, she is installed on the four flight prototype-the T-50, passing tests of in situated near Moscow Zhukovsky outside Moscow. In the words of Dudnik, the first copies of the T-50, collected by at the Komsomolskoye-on-the-Amure Aviation factory flew in Moscow suburbs independently, but on the throughout all route to them was only required refueling of without replenishment of of stocks of oxygen.

On the basis of the oxygen system the T-50 created similar equipment and for uchebno-and-combat airplanes the Yak-130, on the which were originally were installed cylinders. Until the end of 2013 a new system of should also get the flush deck fighter jets the MiG-29K. How to the newspaper marks, orders for such a system of have already placed the of the Ministry of of Defense of Algeria and of Malaysia that are planning to equip the her their fighter jets the family of the Su-30.

Earlier, was reported , that the pilots of fighter planes the T-50 will receive new complete sets Protective equipment such which will allow them to carry forward overloads up to 9G duration of up to 30 seconds and to catapult at an altitude of up to 23 of thousands meters. In the the composition of a kit to of flights to the a big an altitude of will be system is enabled the pressure compensation in the lungs, allowing to avoid the treatment of atelectasis (of collapse of of the lungs).

In the of general the complexity of The Ministry of of Defense Russian commissioned a 60 fighters the T-50, while the need the Air Force in of such airplanes is estimated in 150-200 of units. It is expected that in 2015 the government will begin joint testing of aircraft, and in 2016 the PAK FA will go into service.

Latest News Update:

July 15/13:

India Delays. The FGFA project’s parameters may be set (q.v. April 10/13), but there’s a problem with the R&D deal, which was pegged at $11 billion equivalent. The Times of India external link:

“Defence ministry sources said the inking of the final design and R&D contract for the stealth fighter has been hit by a huge delay, with Russia also jacking up costs for the futuristic project. “It’s very unlikely the FGFA final design contract will be concluded in the 2013-2014 fiscal,” said a source. “The timeframes will now have to be revised. MoD has established a committee of specialists and finance officials to verify the rise in costs. An internal contract negotiation committee is also in progress…”

Russia isn’t going to wait, and will continue development of their version while they wait for India’s signature. Operational testing is slated to begin in 2014. If FGFA negotiations stretch into 2015, the net effect will be to severely delay India’s variant, even as the base Russian design becomes more and more firmly set.

Press conference of "Saturn"

...On the engine for the PAK FA

Asked by reporters on the engine for a prospective fifth-generation fighter being developed by the program "promising aviation complex tactical aircraft" (PAK FA), Fedorov noted that work is being done extremely well under the leadership of chief designer STC them. Arkhip Cradles Eugene Marchukova. Design Bureau NPO "Saturn", headed by chief designer Yuri Shmotinym, did a great job on the new gas generator engine characteristics have turned out much better than expected by the customer. Now comes the final configuration of the motor and coordination with the Yakovlev Design Bureau. Dry questions on placing the engine on the aircraft. President of JSC "UAC" Mikhail Pogosyan puts a condition that the engine installed in the aircraft without any change in the support (now at T-50 or PAK FA fighter jet engines are installed ed. "117" before the new engine). Installing the engine of the second stage will dramatically increase the speed of the aircraft, as the increase traction and acceleration, in addition, the engine will be easier.

It should be noted that one of the conditions for the developer fighter is the price of a new engine - it should not be higher than the price of the engine, "ed. 117", which is set today, and this demand will be met and maintained. The engine in the production of the most cost-effective when it is released in large series, as it is today, for example, the engine AL-31 FP / FN in Moscow "Salute" and Ufa MPO. Today, there is confidence that even at half of the series, which now is, the production of the new engine will be cost-effective. Now an estimated price corresponds to the engine "izd.117."...

MOSCOW, July 15 - RIA Novosti. No deviations from the schedule negotiations on a package of agreements associated with the joint production of a fifth generation fighter between Russia and India is not, told RIA Novosti on Monday, a source close to the negotiations.

On the eve of the Indian newspaper Times of India quoted a source in the Ministry of Defense reported that the signing of the contract for the development work on the Russian-Indian fifth-generation fighter (PMI / FGFA) is delayed because of the increased price of the project by the Russian side.

"This kind of publication associated exclusively political considerations rather than business. Project is profitable both countries, investment - 50 to 50, so any increase in prices and a slowdown in negotiations is not" - said the source.

Meanwhile, a source told the Indian edition, remains a very small chance that the contract for the work on the MIT will be signed in the fiscal years 2013-2014. According to him, the time frame will be revised, with the Defense Ministry set up a committee of experts, technicians and financial experts who will be engaged in checking the validity of value growth.

According to the newspaper, despite the delay in signing the contract with the Russian Federation, India still will not accept the U.S. proposal to buy the F-35 Lightning-II, since a large amount of money already invested in the project of MIT and India can not afford to maintain two similar programs, both from a financial point of view and from the point of view of the organization of technical support.

The agreement on the joint development and production of fifth generation fighter aircraft was signed on 18 October 2007 in Moscow. It is the largest joint project of Russian-Indian military-technical cooperation. In December 2010, FSUE "Rosoboronexport" company "Sukhoi" and Hindustan Aeronautics Limited (Hindustan Aeronautics Limited) signed a contract for the development of conceptual and technical design of aircraft.

At the heart of the Indian "perspective multirole fighter" laid a Russian fighter of the 5th generation "Sukhoi T-50" or PAK FA with the structural modifications to the conditions of the air forces of India. Initially, the Ministry of Defence of India has made a request for 166 single rooms and 48 double machine, but later decided to buy only single.
