    Company Su-30MK, ‘503’ previously used to test Irbis-E radar, it’s speculated that it will be (or has commenced) flight testing of Tikhomirov’s AESA radar for PAK-FA (pic taken 24/05/11 @ Zhukovskii):

    All I can say is – Well done!

    Yeah, it means that the initial batch of production PAK-FAs will at the very least have 17.25T thrust engines.

    Congratulations Sergei Bogdan!!

    117 installation compared to 117S:

    I think being part of the design team, Chepkin’s referal to the ‘Type 30’ means it’s the 1st baseline example under Project 129, as is currently rated @ 15% increased thrust over the 117, probably by using those Salyut 5G components (I used 15% in the above calculation)

    His actual quote was:

    [“тип 30”]…По своим параметрам он на 15-25 процентов превосходит “117-й”.

    [The Type 30’s] parameters are 15-25% greater than the 117’s.
    Imho, they’ve achieved the 15% and are working towards the 25%, with desirable T/W vis-a-vis fuel fraction ratios etc.

    Chepkin also names the Chief Designer of the 117 as Evgeny Marchookova,
    so long as there’s no reporting errors/misquotes, then Chepkin’s words are kosha.

    It’s the first time I seen this guy smile:

    …but I guess the T-50 will be making alot of people smile this August ;).

    if anything, the FGFA need more thrust than Pak-Fa :rolleyes:

    The IAF will induct single seaters initially, hence both Indian & Russian initial batches will utilise the ‘Type 30’.

    Engine: Mil.Thrust/Afterburner:

    AL-41F1S (“Item 117S”) 86kN/137kN
    АЛ-41Ф1С (“Изделие 117С”) (8,800kgf/14,000kgf)

    Al-41F1 (“Item 117”) 86kN/147kN
    АЛ-41Ф1 (“Изделие 117”) (8,800kgf/14,989kgf)

    “Type 30” (“тип 30”) At 15% increase:
    98.9kN/169.05kN (10,084kgf/17,238kgf)

    “Item 129” (“Изделие 129”) 107kN/176kN (10,910kgf/17,947kgf)

    According to Chepkin, yes

    The ‘Type 30’ maybe a further development of the 117 using components from MMPP Salyut (who’s head stated last year that they already had components for the 2nd stage engine ready to be integrated). It would also explain the drawn-out contractual wrangling settled only in January, after heavy government pressure/intervention- which is understandable if Salyut was ‘surrendering’ their own developments and IP to Saturn.

    Chepkin hints that the ‘Type 30’ may receive a new AL-XX designation soon, and ties in well with recent reports that the 2nd stage 5G engine development is ahead of schedule, with delivery slated for 2015.

    It’s also possible (as already intimated elsewhere) that this is the engine for the FGFA, hence the demonstration to the Chief of the IAF the other day, which would mean this is still not the definitive engine for the RuAF machines (so-called Izd. 129).

    Barring any mis-quoting and/or poor journalism- it’s very good news indeed :).

    MMRCA decision by December (?):

    With only Typhoon and Rafale left in the reckoning after the “gruelling and transparent” technical and flying evaluation, MoD’s Technical Oversight Committee (TOC) and Technical Offsets Evaluation Committee (TOEC) are now working to submit their reports soon.

    “We should be ready to open the Typhoon and Rafale commercial bids in July,” said the source. Thereafter, it will take another month to determine the lowest bidder (L-1) because of “huge mathematical and data verification” of the lifecycle costs of operating the jets over a 40-year period. Commercial negotiations with the L-1 vendor will then begin before the final contract is ready for signing by December.

    Asked about “points” being raised by eliminated vendors, sources said only Rafale and Typhoon were found “compliant” on all the 643-660 technical attributes or ASQRs (air staff qualitative requirements) laid down to meet IAF’s specific operational requirements.

    “Our test pilots flew 222 sorties, over 270 hours, on the six fighters in different weather conditions in India and abroad. Each vendor was informed of its jet’s performance at every stage… they have no reason to complain,” the source said.

    Obviously it’s a plot orchestrated by the CIA and Lockheed-Martin.

    Yeah, they didn’t like the tone of this guy’s statement:

    Rafale was designed with low RCS as an afterthought (but one which they were able to implement in the physical structure of the aircraft more noticeably than with Typhoon).

    Agreed. Both Eurofighter & Rafale are 4.5G aircraft, let’s not try to kid ourselves they’re anything else. That upon delivery to the IAF they’ll exhibit so-called 4.5G+(+) capabilities is a given- that’s why only these two made the technical downselect. It must be be immensely gratifying for their respective manufacturers’ that both aircraft were so far ahead of the US rivals that none of the latter even made the cut.

    As for Rafale’s stealth vis-a-vis Typhoon- the two are probably evenly matched. I do like the Rafale, however, I’m sceptical about how effective those saw teeth on the Rafale will be given those gaping panel joints utilising no gap filler and/or sealants (definitely looks like an afterthought- see link).

    The antenna size argument doesn’t wash, for example the Russians rate the ‘Irbis’ as second only to AN/APG-77 precisely because of it’s scanner size and power output.

    The negotiations for commercial terms begins next month, so we can ease up on the flag-waving (unless you’re BAE Warton!):

    And Dassault/Thales/Snecma don´t see India as their best/biggest export chance?
    If any party isn´t willing to invest to meet off-set requirements, their bid will be thrown out.

    Dassault et al may be ready and willing, but remember the offsets are worth some $4.75bn, and French unions (not for the first time) may have the final word.

    Having said that, I came across this interesting snippet regarding Snecma’s M88 ECO core integrated with Kaveri, and its application on not only the AMCA, but also on AURA (India’s UCAV project). The rumours of Dassault inviting Indian participation in nEUROn (or a similar jv) may hold water afterall (pg.27).

    It’s a video still of the T-50’s composite wing production process. The still shows an aluminium gauze to reinforce the layered composite structure.

    EADS beats SAAB in the R&D centre race (where is Dassault?)

    Bengaluru: Cassidian, the defence and security division of European Aeronautic Defence and Space (EADS), on Wednesday said it has opened a new engineering centre, the first of its kind from a global defence firm stable, in the city.

    The centre will work in the areas of radars, protection suites, avionics, information technology and three-dimensional visual simulation, aero-structure and aerospace modelling and simulation.

    “This is the first defence-oriented engineering centre operated by a foreign company in India and therefore a landmark achievement towards Cassidian’s strategic goal to establish a long-term partnership with India,” the company’s chief executive officer Stefan Zoller said here.

    The new centre is staffed almost entirely by Indian engineers who have undergone extensive training in Europe. It has plans to increase the current number of 60 employees to over 200 by the end of 2012.

    “The centre in Bangalore is a perfect example of our commitment to increase our industrial footprint in this rapidly growing country and to create a wide range of opportunities for industrial cooperation,” Zoller said.

    The centre will be the first Cassidian engineering development effort outside Europe. It will be integrated with the firm’s engineering organisation to participate in Indian and global programmes.
