    And another proof of how desperate you are to keep bringing up Dassault in every unrelated thread. Pic is the French Average American as it seems. :biggthumpup:

    It was only for the period of work from 2010 to 2013. The program cannot continue until the R&D contract is signed.

    Basically we now have to pay money for prototypes and the continued development of the program on a larger scale. The program can only move to its most advanced state if India pumps in money and assures orders, I think 154 initially and 350 potential.

    Possibly and if you look on top of that cone, that appears to be a passive MAWS window.

    That's a compliment.

    You see, I have some skill.

    Passive DAS (101KS-U) are all around the jet (most likely bi-spectral; IR & UV) -

    ...and if you note the positions of the two 101KS-O DIRCM mounts (one on the bottom of fuselage and other on the dorsal hump) you'll see that their function is closely coupled with the DAS. The bottom DIRCM is close to the fuselage DAS while the dorsal DIRCM can be used in conjunction with the side & rear DAS sensors. The KS-U detects a missile launch, and the KS-O blinds it (provided it's IR-guided ofcourse). The dorsal unit takes care of WVRAAMs while the bottom one is useful against infrared SAMs (or AAMs launched from below).

    Where's the DIRCM on the bottom of the fuselage?

    I'm afraid the picture I made isn't as self-explanatory as I intended it to be.

    :tongue:

    Note that all prototypes don't have all sensors installed (this one for example doesn't have the bottom DAS).

    Carbon Ghosts': How Coal Plastic Will Help Russian Planes to Dodge Enemy Radar
    13:37 29.07.2017(updated 18:44 29.07.2017)
    Composite materials are all the rage today with Russia’s fifth-generation T-50 fighters and, Ka-52 and Ka-62 helicopters making extensive use of polymeric carbon plastics and other high-strength materials, rendering them virtually invisible to enemy radar. Sputnik looked at the way composites can help planes fly better and dodge enemy radar.

    The use of carbon-plastic composites, which are lighter than duralumin, titanal and other alloys used in aviation construction, enabled Russian engineers to make the T-50 just as undetectable by radar as the US F-22 Raptor stealth fighter.


    With 70 percent of the T-50’s airframe consisting of composite materials, its developers say that the effective area of the plane’s reflecting surface is just 0.5 square meters. For comparison, in the heavy "metal" SU-30MKI fighter this indicator is 40 times higher and is equal to 20 square meters.

    Figuratively speaking, the T-50 is seen on a radar screen as a tiny 50 cm x 100 cm “spot.”

    The T-50’s designer, Alexander Davidenko, told Zvezda TV that due to the use of composites the aircraft has four times fewer parts compared to the Su-27, weighs less and is easier to mass produce.

    Composite and radio-absorbing materials will also find extensive use in Russia’s new PAK DA strategic bomber. Designed as a “flying wing,” just like the US B2 Spirit strategic bomber, the PAK DA will be much less visible to radar than its American counterpart.

    Meanwhile, the aircraft factory in Ulan-Ude in eastern Russia has completed flight tests of the new regional TVS-2-DTS plane, almost entirely built from composite materials.

    The use of composite materials dramatically reduces a plane’s visibility, as electromagnetic signals are not reflected from carbon fiber surfaces and passing through them or getting absorbed.

    As a result all a radar operator sees on his screen is blank space.

    The reduction in visibility is also ensured by the irregular geometrical shape of the plane’s surface, which is simpler to “mold” from carbon plastic than from metal.

    Indo-Russian Gen-5 fighter gets green light; experts find “no conflict with indigenous AMCA fighter”

    [​IMG]
    $6.1 billion negotiated for joint R&D; prototypes could be flying in India in 3 years

    By Ajai Shukla
    Business Standard, 31st July 17



    The decks are clear for the ministry of defence (MoD) to sanction the long-delayed Indo-Russian project to jointly develop a cutting-edge “Fifth Generation Fighter Aircraft” (FGFA).

    Business Standard learns that an Experts Group, headed by Air Marshal (Retired) S Varthaman, has submitted a report on July 7, finding that the FGFA project would be beneficial to India.

    After MoD bureaucrats objected to the FGFA project on the grounds that it might duplicate, or hinder, the indigenous Advanced Medium Combat Aircraft (AMCA), former defence minister Manohar Parrikar set up the five-person Experts Committee to consider this question.

    After deliberating for six months, the Expert Committee has ruled there are no conflict lines between the FGFA and AMCA. In fact, the technological expertise that Indian engineers and designers would gain from working with Russian experts would feed positively into the AMCA project.

    Meanwhile, the Defence R&D Organisation, through its subordinate Aeronautical Development Agency, can continue designing the entirely indigenous AMCA – based on its experience in developing the Tejas light fighter.

    New Delhi and Moscow signed an Inter-Governmental Agreement (IGA) a decade ago, in October 2007 for Hindustan Aeronautics Ltd (HAL) to partner Russia’s Sukhoi Design Bureau in developing and manufacturing the FGFA. Between 2010-23, HAL and Sukhoi spent $295 million each on a “Preliminary Design” phase.

    Now, the two sides are required to sign an “R&D Contract”, which the MoD told parliament on July 5, 2013, would “define the total scope; the work share and responsibilities of each side; and the financial implications of the programme.”

    Reliable sources tell Business Standard that India and Russia have negotiated a draft R&D Contract, which commits both sides to spending $6.1 billion on the project –$3.05 billion each.

    While India has dragged its heels for a decade since signing the IGA, Sukhoi Design Bureau has already designed the basic flying platform, named Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii, or “Prospective Airborne Complex of Frontline Aviation” (PAK-FA).

    At least six PAK-FA prototypes are already participating in flight-testing and flying displays, such as at the recent Paris Air Show. The draft R&D Contract commits Sukhoi to build the eighth, ninth and tenth prototypes for flight-testing in HAL, by Indian Air Force (IAF) pilots.

    That means that, if the R&D Contract is signed this year, IAF pilots could be testing FGFA prototypes in Indian skies by 2020.

    HAL chief, T Suvarna Raju, declined to comment on the Experts Group report, but told Business Standard that an early conclusion of the R&D Contract would allow HAL to play an important role in developing the PAK-FA flying platform into a combat effective FGFA for the IAF.

    “If we join now, we will still get a significant part of the work share, thanks to delays in the PAK-FA project. HAL would co-design the avionics, including navigation systems, radars and weapon aiming devices. This is the heart of the fighter’s combat ability”, says Raju.

    Delays in the PAK-FA’s development are attributable partly to hitches in designing a new, powerful engine that would let the fighter “super-cruise”, or travel at supersonic speeds on “dry thrust”, without engaging its fuel-guzzling afterburners. While engine-maker NPO Saturn has struggled to perfect a secretive new engine, dubbed the Izdeliye 30, the PAK-FA has been flying with the relatively underpowered AL-41FI engine – an uprated version of the Sukhoi-30MKI’s AL-31 engine.

    However, at the Paris Air Show in July, Russian designers have claimed that the PAK-FA’s new engine would be ready to fly by December.

    For the IAF, the FGFA project opens up the assured development of heavy fighters that will succeed the Sukhoi-30MKI, many of which have already completed 15-17 years in operational service. In the medium fighter category, the IAF would have two Rafale squadrons, possibly three if a follow up contract is signed for an extra squadron; and also three upgraded Mirage-2000 squadrons. In the light fighter category, there will be four squadrons of Tejas Mark 1A, and another light fighter for which procurement has been initiated. Amongst the contenders are the Swedish Saab Gripen E, and Lockheed Martin’s F-16 Block 70.


    The FGFA is equally crucial for HAL’s Nashik plant, which is now building the last 35 Sukhoi-30MKI fighters of the 272 fighters contracted by the IAF. At a build rate of 12 fighters per year, the Sukhoi-30MKI production line will be idle by 2020. It remains unclear how many FGFA units the IAF will eventually buy, but for HAL Nashik, a production order is essential.

    Too good to be true.
