    I. Fedorov – Executive Director of “NPO Saturn” is convinced that the “Izdelije 117” engine (for Pak Fa) will within 3 years be equipping all other Sukhoi aircraft

    All “Su” aircraft will use “Product 117”

    – Ministry of Defense has contracted serial production of “product 117” engines or has only funded engines for testing?

    – Their (Min of Def) money is for the “117”, we have not invested in it. Together, Sukhoi, UMPO and “Saturn” invest only in the modification of “117S”.

    Ministry of Defense has already laid the financing for the supply of engines for serial fighters. I am confident that within three years all the modern “Su” aircraft will fly a “117 product”. The engine is very good, almost completely satisfies “fifth generation” requirements.

    – How many engines already released “117”?

    – I’ll say this: the number provided for is enough for the full fleet of Sukhoi.

    – How many hours have flown the engine on the Su-27M?

    – There were a few flights of 45-50 minutes duration.

    – Where is serially produced “product 117”?

    – At the moment, 18% produced by “Saturn”, 82% by UMPO. When the big series production begins, the production can be fully transfered to UMPO . Of course, our company in this case would need to find a replacement for the lost income. This issue is being dealt with at JDC level.

    – Negotiations with the Salyut Co-operation in building the engine for the PAK FA are going on?

    – Project PAK FA as the leader of this trend in the JDC I keep abreast on a daily basis. As part of the JDC is negotiating with “Salute” on the issue. But the final word rests with the customer, ie the Ministry of Defense.

    New Targeting System Created for Tu-22M3 Bombers

    A new targeting system has been developed which will improve the capabilities of the the Tu-22M3 strategic long-range bomber, ITAR-TASS reports quoting the general director of the Gefest and T developing company, Aleksandr Panin. According to him, the new system already has been delivered to Russia’s air force and has been proved during combat training of bomber flight crews.

    The targeting system, which consists of bomber systems and an automated ground complex, will allow the Tu-22M3 to make precision bomb strikes in poor weather conditions. Moreover, the new development allows the bomber crew to exchange data with other aircraft and with ground controllers to more effectively control strike groups, including operational in-flight re-targeting.

    The Russian defense ministry announced at the beginning of January 2010 that by 2015 nearly 30 percent of Russia’s long-range aircraft will be updated. The upgrade process applies to both strategic Tu-95MS and Tu-160 missile carriers and Tu-22M3 long-range bomber missile carriers. The technological improvement of the airplanes will be done by expanding the range of weapons and the installation of new information systems.

    It was tested during last year’s exercise

    Russian bombers test high-precision weaponry during drills

    SVP-24 allows target data to be automatically transmitted by on-ground spotters and received by ground attack aircraft during combat.

    Drobyshevsky said the drill involved quick retargeting of the aircraft in response to a decision made by a unit commander on the ground, who shifted priority to a new set of targets during an intense battle.

    I’ve updated the rendition. The tyre diameter/height figure is from the manufacturer. I’ve taken into account the off-line photo shot and, to some extent, the engine toe-in.

    IMO, Otaku’s rendition is the best guess so far….

    Hmmm…it “severely degrades performance” on the T-50- but not the uber F-22. In fact they were purposeful in having straight thru inlets to negate all the VLO shaping :rolleyes:

    The “squashed” exhausts on the F-22 also reduce the engine’s effectiveness somewhat…. by about 10-20% according to some estimates.

    ————————————————

    Interesting close up (Flateric’s pic) of the T-50 intake (edited to show some details)….obviously they aren’t straight through inlets like many assume.

    It’s possible (maybe even likely) that the T-50 has intakes with movable ramp

    Why would they give that figure, rather than what they anticipate to reflect a production model? Why wouldn’t they mention that’s what they were saying, if that is indeed what they did?

    According to their research, 0.3m2 is the about the maximum that can be achieved by the shape of the aircraft (with current technology). It’s mentioned in one of their research papers from the early 2000’s…..since the application of RAM wasn’t mentioned, I’m assuming they meant just the shape of the aircraft.

    The article claims that the figure for PAK-FA corresponds to the figure declared for the F-22, in the first place.

    The RCS of 0.3-0.4 sqm very probably refers to overall RCS from all angles, unlike the 0.000x figures which are most likely frontal aspect RCS. Looks like the same thing, just evaluated in a different way..

    The 0.3-0.4 m2 probably refers to the “bare” (naked) fuselage without the RAM

    Anybody can claim anything. The question is, why should anyone believe them? ;)…….

    Looks like somebody believed them…..between 01:20 – 01:30 on the video below

    Actually it’s more like this:

    Not quite….the intakes aren’t completely straight (even just looking from the outside). Something like ) (

    The engines will have reduced radar and IR signatures as stated already several times by officials. We’ve already speculated on the methods that might be achieved.

    The Russians believe their approach is better overall compared to closely spaced engines with 2D thrust.

    Nice pics from the Sukhoi visit, thanks.

    Some clarification on the capacity of the internal weapons bays (RIA Novosti – russian language version)

    (translation)
    The aircraft has a large internal weapons bay. It can accommodate up to eight missiles R-77 air combat or two large guided bombs weighing 1,500 kilograms. The Fighter is capable of carrying two extra long-range missiles from design bureau “Innovator” on external slings. These missiles are capable of destroying aircraft at a distance of 400 kilometers, for example AWACS type

    Not sure if my question is relevant to this post, but where is the best source for up-to-date information about the state of Russia’s air force, and its plans for the future?

    I keep picking up bits-and-pieces that they’re going through a major reinvestment but can’t seem to find specifics.

    In short the new structure of the VVS should look something like this:

    4 x Operational Commands
    33 x Aviation Bases
    13 x Air Defence Brigades

    The number of crews reduced by 40% (approx. from 12000 to 7000)
    Number of officers reduced from 65000 to 38000

    The aim of the reform is to concentrate resources in a smaller number of larger bases, retire older equipment in stages and increase the readiness of units.

    The above is based on the following report:

    Pretty interesting and detailed promotional clip about the Mi-28N(E).

    It’s in 2 parts:

    You’re all arguing over an incorrect press headline…..or to be more correct, the anti-Russian crowd had a wank over it. Anything will do to confirm their fixed false belief that is resistant to reason

    2013 prototypes at Lipetsk – 2015 target for induction of first examples….that’s all we’ve got so far.

    I would guess first operational unit no sooner than 2017

    No, no, no, no.

    Its subject to the same problems as the F-22.

    The heat is in the plume, not surface heating of the nozzle.

    The YF-23 sheilded the initial plume………….

    It doesn’t necessarily mean the T-50 has to use the same solutions.

    The text clearly says treatment for “exhaust + afterburner”…..a “cooling sleeve” has also been mentioned as part of the definitive engine for the T-50.

    There are pros and cons to everything, but closely placed engines have some negative issues such as reduced thrust due to the mutual interaction of the gas jets.

    Widely spaced nozzles reduce drag, allow better exploitation of the engine thrust, 3D vector thrust becomes possible apart from the already mentioned more rapid cooling of the exhaust jets.

    Just found that without any additional link/source, but I thought the second flight was done on 6. February already ???

    Deino :confused:

    Looks like the 6th of February flight was unofficial if we are to believe the Sukhoi sources.

    The T-50 engines might have a layer of ‘ceramic’ RAM as a way to reduce radar and IR signature

    The following quote is from a 2003 presentation about Russian stealth techniques

    The ITAE and its partners use plasma technology for applying ceramic coatings to the exhaust and afterburner.

    Multi-layer coatings formed from microparticles of dielectric, metal, or semi-conductor material are deposited by an arc-discharge plasma under atmospheric pressure.

    Challenges include the need to keep the ceramic bonded to the metal structure over a wide temperature range (600°C to 1,200°C), despite the fact that the materials have widely different thermal-expansion characteristics.

    The coating materials also need to maintain constant electrical characteristics in the face of widely varying temperatures.

    Researchers describe this problem as “partially solved,” and engines treated with ceramic RAM have already been flight-tested

    Also the heat emissions from widely spaced engines (like the T-50) will cool quicker
