    ^Yeah Yeah. The latest gutter move by the western media. Hey there's a Muslim republic in Russia. Lets make up some stories about how they treat gays.

    Only peripherally related to the RuAF but the engines are running hot and there have been some taxi tests now:

    Yes, indeed! Pretty exciting to see a project that one could have been forgiven for considering vapourware only 10 years ago or so become the most advanced single aisle airliner in the world! I mean, a Soviet era production plant (not even one of the biggest, and without experience in airliner production worth mentioning) buys a marginalized design bureau (the Yak-130 is one of the most influential trainers in recent history, but the company wasn't exactly healthy and their airliner credentials are not that brilliant either). Doesn't sound particularly auspicious, but the result speaks for itself - consider my hat tipped!

    A couple of PD-14 nuggets which aren't widely known:

    - fuel injector nozzles will be 3D printed, as on the CFM LEAP-1 family
    - as on both Pratt's GTF and CFM's LEAP, LP turbine blades will be TiAl
    - the nacelle thrust reverser is electrically actuated and has a non-bifurcated "O-duct", both like the LEAP-1C

    The only major innovations that it lacks compared to its Western competitors are a composite fan case (both Pratt & CFM), a reduction gear (Pratt), CMCs (CFM) and composite fan blades (CFM). Of these, the composite fan blades and case as well as the gear are not that critical for the PD-14 given its lower bypass ratio (shorter, lighter blades that are easier to contain), as the Engine Alliance GP7200 demonstrates conveniently. This collaboration between PW & GE has a similar bypass ratio and notably did NOT adopt GE's composite fan technology from the GE90 but like the PD-14 uses hollow titanium blades (made by PW). RR, who pioneered the technology, has pushed it to even higher BPRs on Trent 1000, 7000 & XWB, citing better aerodynamic properties (thinner, sharper blades IIRC), but will soon transition to composite blades. While GE decided to skip that step altogether when they designed the GE90, my impression is that for the bypass ratio achieved by the PD-14, hollow titanium blades are in fact the solution of choice.

    So there will be a slight fuel consumption penalty (due to its lower BPR, partially mitigated by being the smallest and lightest of the three), but other than that it is an extremely creditable effort.

    Some significant news for Russia's IADS stealth denying future:

    http://function.mil.ru/news_page/cou...2123523@egNews

    A contract for 11 Nebo-UM radar sets to be delivered by the end of 2019.

    I wonder why they need a Meter Band/VHF radar when L and S band are quite capable of detecting Stealth Aircraft at long ranges ?

    More likely these VHF will just a role of tripwire to warn of Stealth Aircraft guiding the L/S band to look in the right direction early on focus on specific sector and track/guide missile to the target.

    X-band is still the best option for targeting solution. L/S-band is better for early warning and detecting stuff at long range.

    Dont want to say told you so, actually, yes i do. Told you so;

    По словам человека, близкого к военно-промышленной комиссии, решено отказаться от полномасштабных работ по таким затратным проектам, как новый авианосец, новый эсминец (предлагалось сделать его с атомной энергетической установкой), новый стратегический бомбардировщик ПАК ДА, перспективный истребитель-перехватчик. Как говорит собеседник, по самому ПАК ДА будет вестись только научно-исследовательская работа, а опытно-конструкторские работы пройдут по его компонентам.
    According to a man close to the military industrial commission, it was decided to abandon full-scale work on such costly projects as a new aircraft carrier, a new destroyer (it was proposed to do it with an atomic power plant), a new strategic bomber PAK DA, a promising interceptor fighter. As the interlocutor says, the PAK DA will only conduct scientific research work, and the experimental design work will be carried out according to its components.

    Thanks, Tu-160M2.

    Lider was cool but it was also insane, no tears shed whatsoever for the new carrier, but shame about PAK-DP.

    key word is full scale work. It is understandable those things will be pushed out post 2025 procurement. near term is MIG35/A-100 and Tu-160 upgrades. there is still T-50 pending.

    We don't know if Tu-160M2 is to blame for the other axed program.. something tells me the overall economy is the issue..
    What kind of Destroyer class was on the table?

    And... there it is. The token jab at the Russian economy. When Japan decides not to continue its 5th gen program. Nothing is said about the Japan economy. But for Russia, everyone is an armchair economist. Allow me to correct your wrongheaded assumption. There is no such funding issue. This big projects are decided on, from a whole host of factors. Not simply funding.

    From FT. (western fin media)

    Quick little lesson on intl banking. When a country is experiencing deleveraging and capital outflow, it sells forex reserves. When a country is stable, it buys forex reserves.

    Russia's central bank will spend Rbs6.3bn ($110m) a day on forex transactions from February 7 to March 6, the finance ministry said in a statement on Friday. The move follows a steady rally in the Ruble.

    Yeah haavarla, the economy is the bigger picture issue of course but having the extremely expensive Tu-160M2 program isnt helping. Lets say the economy was exactly the same, but there was no Tu-160M2, PAK-DA would have much much higher chance of survival despite the economy. As of now Tu-160M2 is basically directly competing with PAK-DA despite them being quite different.

    @ haavarla
    It seems me that he was asking about the higher lenght not the smaller.
    In every case each of such bnd is better at a certain phase of the engagement process: metric band is the lest affected by the stealth feature but it is not precise, so it will gave you an early warning but just a general idea where the plane really are. L/S band is still capable to get a good range and an overall good precision in the same time, while the X band is the one for targeting but would not get nothing operating alone..
    So first one discover the menace , the second one refine the search and the third one does the killing.

    With Tu-160M2 in the picture, PAK DA should be redesigned as a regional bomber powered by 2x (non-afterburning) NK-32. Such an aircraft would be more flexible and affordable and would still have more thrust than a B-2.

    Holy Macaroni!! That Lider Class DD sure was one ambitious Concept! No wonder that got axed.

    On a pure figure lvl, its sure easier to fund program A that cost $2.8billion vs program B that cost $7.8billion.

    Now guess which would be Tu-160M2 and PakDa..
    PakDa didn't stand a chance in hell. The PakFa program is still far from completed and when it finaly does, there would still remain the not so small task of allocate funding to procure them in numbers and likewise extra funds to service them with new weapons.
    Then we have a long list of other stuff that need modernizing.

    Look KGB.. i'm not bashing Russia here.
    It is nothing short of impressive how much defense capability they can get for the relative small defense budget.
    Lets be serious here, something gotto give

    Lider was not insane, and it will still happen, but look @ what is happening with frigate (22350) procurement- number was halfed and shifted back half a decade, so talking about Lider for now is just a joke, subject will be revisited in the 2020s.

    As for Tu-160M2.....maybe PAK-DA is just too expensive and ambitious for the industry to handle right now, given tactical needs and the economy. Tu-160M2 or nothing for ~10-15 years.....
    At least titanium production is being re-established at Kazan, and the plant is getting back in some kind of shape.

    The PAK DA is supposed to have 4 NK-32s? How large is it supposed to be?

    When i said "axed", i didn't mean like forever. But pushed back axed. That goes for all of those program.
    We can't really claim Russia is running out of time.. as a NC and Energy Superpower they got all the time in the world to fund their defense sector.
    And besides, i'm sure the Putin Team know a thing or two about economy(not gonna fall for the long standing obvious US arms race trap again), so why/who are we to say otherwise.

    @ RaDisconnect
    Almost the same than Tu-160 if they have to use the same titanium main body structure.
    One would have afterburner, the other not.

    We will have to wait till July to get full picture of SAP 2018-2025 rather than relying on unsubstantiated report.
