    The official patents make it clear that the intakes aren’t straight-thru, and I believe them.

    Also, that’s an IGV (inlet guide vane), simply follow the inner circumference round to give you precise location:

    I’m surprised and mildly irritated at the quality of some of those pics, most are significantly worse than those released immediately after T-50-4’s first flight last week. I wonder if they’re just HD video prints, as yet no-one has put a name to them…or is this the new norm courtesy of the ФСБ.

    Vladimir Ivanenko’s (quality) high-res. images of T-50-3 are back up:

    Dude who probably played a part in T-50-4’s structural modifications gets an award:

    Инженер-конструктор первой категории ОКБ Сухого Валентин Мартынов стал лауреатом Национальной премии “Золотая идея” в номинации “Молодые таланты” за достижения в области военно-технического сотрудничества, разработки и производства образцов вооружения и военной техники. Он награжден почетным дипломом за работу «Топологическая оптимизация конструктивно-силовых схем элементов планера изделия перспективный многоцелевой истребитель (ПМИ)».

    Решение этой задачи является одной из приоритетных в авиастроении и сводится к нахождению оптимального соотношения веса/прочности (жесткости) при соответствующих нагрузках, действующих на конструкцию самолёта.

    OKB Sukhoi’s Category 1 engineer Valentin Martynov was awarded the ‘Golden Idea’ national prize in the category “young talents” for achievements in the sphere of military-technical cooperation, the development and manufacture of examples of armament and military equipment. He was awarded an honorary diploma for the “Topological optimization for design elements for use in the future multirole fighter (PMI)” [aka PAK-FA].

    The solution of this problem is one of the priorities in the aircraft industry and comes down to finding the optimal ratio of weight/strength (hardness) accounting for the loads acting on the structure of the aircraft.

    yes, there seems to be something added to the yellow upper panel(is also wider than on T-50-1) in front of the engines, whether it is a reinforcing structure I do not know, but it certainly looks that way.

    Yeah, from this shot you can clearly see that ‘ridge’ or clear height difference in the panelling (whether for aerodynamic function or other). Also despite indications of riveting from your screen grab, it is difficult to ascertain whether or not it’s one piece.

    Speaking of changes, Jō Asakura is right. It seems there is a structural modification at the top of the aircraft: I tried to remove grain and color corrected to make it more visible.

    Here’s some clearer footage, your screengrab is @ 0:22s, then when it’s taxying you can see a distinctive (possibly faceted) longitudinal ridge @ 0:35s.

    If you compare:

    It looks like it’s the covering for a new fundamental structure, probably a titanium spar to remedy the cracks found on ’51’, though the latter was modified on site @ Zhukovskii.

    Possible structural modification visible as yellow ‘bar’ across the upper-mid fuselage.

    A flawless 40 minute flight, Congratulations to Sukhoi & KnAAPO!!

    In many Eastern cultures (probably including Russia’s far east) the number ‘4’ is considered unlucky, and especially after what happened to ‘904’, there may have been a certain amount of nervous apprehension*.

    This one is supposed to embody significant structural modifications after ’51’ suffered (buffeting?) cracks, hence the long overdue first flight. Good news for His Imperial Majesty, Lord Putin on the day of his ‘State of the Nation address’ and will certainly put a spring in his step as he heads to New Delhi on December 24th to conclude the $multi-billion FGFA deal.

    *Not that I’m superstitious or anything, the timing of this post (12:12, 12/12/12), is purely coincidental! 😉

    Just as a comparison an AMD computer with x86 based CPU will deliver 16 TFLOPS (that is 8-16 times the CPU power of the F35) the PSU needed is less than 1000 Watts. Yes, its a standard ATX motherboard.

    So your 200KW are not needed, 3-4 KW is enough and that is easily cooled. What was impossible in 1999 or what was ground breaking performance in 2005 is what you can do with an iPhone today. iPhone 4S gives 51 GFLOPS in pure processing power (7,2 @ 200MHz and no relative drop off @ 300Mhz and the processor runs at 800 MHz). So in theory the F22 could run one iPhone 4S and more than double the capacity it currently has.

    Cheers.

    Not quite, you cannot compare regular commercial CPUs like the ARM chipset on the iPhone 4S with older architecture, redundancy & cooling utilised in the 2 Hughes’ Common Integrated Processors (CIP) aboard the F-22.

    Having said that, the progress of current parallel architecture’s computing grunt vs. power consumption is truly astounding. Using your example of the F-35’s >1 TFLOPS, a similar commercial system available next year:

    The new Xeon Phi 3100 coprocessor family is specifically targeted at workloads that are “compute-bound”, such as life-science applications like protein folding and financial simulations like stock market forecasting. The Xeon Phi 3100 offers 1-teraFLOPS (1000 gigaFLOPS) and support for 6-Gbytes of memory with 240-Gbytes per second bandwidth–all at less than 300 Watts power consumption.

    The Xeon Phi 5110P is shipping today to select customers, with general availability slated for Jan. 28, 2013 at $2,649. The Xeon Phi 3100 coprocessor will be available during the first half of 2013 at less than $2,000.

    http://goparallel.sourceforge.net/wp-content/uploads/2012/11/rcjXeonPhi-1024x665.jpg

    Intel’s Xeon Phi now comes is two flavors–the 3100 (top) which offers screaming speed at 300 Watts, and the the 5110P (top) which at 225 Watts does not require a fan.

    EADS Governance and Shareholding Structure Receives Far-Reaching Overhaul

    Leiden, 05 December 2012

    •Present shareholder pact expected to be replaced by a normal company governance scheme
    •Daimler AG and Lagardère SCA to largely reduce their stakes, Germany and France intending to ultimately hold up to 12% each, Spain circa 4%
    •EADS intends to propose a share buy-back of up to 15% of outstanding shares – subject to market conditions and shareholder approval
    •Free Float of EADS shares should therefore ultimately increase from 49% to over 70%
