    Or the fact that Knaaz is nearby .

    Good to see that the Su-35's production/induction issues seem to be slowly getting regulated.

    UEC is preparing for the establishment of the engine with a thrust of up to 35 tons

    http://www.ato.ru/content/odk-gotovi...goy-do-35-tonn

    United Engine Corporation (UEC) is preparing for the creation of high-thrust turbofan engines for advanced civil aircraft. As told at the last in the Central Institute of Aviation Motors (CIAM) Conference "Aero Engines of XXI Century" Deputy General Designer of the corporation Victor Belousov, to this end, a member of the JDC Perm company "" OAO is studying the possibility of increasing the gas generator of the new PD-14 engine.

    PD-14 with a thrust of 14 tons is designed for Russia's new single-aisle aircraft MS-21. In late October began its flight tests on a flying laboratory IL-76LL.

    According to the chief designer of the engine family of PD in the company "" OAO Igor Maximov, in the line of big motors base is supposed to make the PD-35 with a thrust of 35 tons. For the new plant is expected to scale gasifier from the PD-14 with the addition of an extra step at the outlet of the high pressure compressor . As a result, the number of compressor stages and turbine PD-35 will be 9 + 2, the diameter of the inlet to the compressor will rise to 815 mm compared to 582 mm for PD-14. It is assumed that the diameter of the fan motor will make a new 3100 mm, length of the engine - more than 8 m, weight - about 8 tons.

    On the basis of the PD-35 will be developed with a thrust power plants 28 (PD-28) and 24 m (PD-24). The first two engines planned to offer two options and chetyrehdvigatelnyh promising widebody long-haul aircraft, the last - to haul widebody aircraft and long-term heavy military transport aircraft, it was noted in the presentation of the representative of the "" OAO.

    Possible applications of the new engine could be a wide-body aircraft, which are jointly developing the Russian United Aircraft Corporation (UAC) and the Chinese corporation COMAC. It is expected that the aircraft seating capacity up to 280 people. C929 with the working title will make its first flight in 2021 and will be commissioned in 2025

    Victor Belousov said that similar work on the high-thrust engines lead to other enterprises of the holding - in Samara company "Kuznetsov". It considered the possibility of the development of power plants thrust up to 35 tonnes on the basis of the gas generator of the turbojet engine NK-32, which is now installed at strategic bombers Tu-160. According to Belousov, both options are considered as a promising power unit with direct drive and driven through the gearbox.

    "Ilyushin" develop a passenger version of the Il-96-400T
    January 13, 2016 Maxim Pyadushkin

    http://www.ato.ru/content/ilyushin-r...iyu-il-96-400t

    The company "Ilyushin" plans to develop a new wide-body passenger modification of the Il-96. "We go out with a proposal to launch the initiative on the basis of the Il-96-400 passenger aircraft," - said the January 13 General Director Sergey Velmozhkin.

    The original version of Il-96-400T designed as a cargo version of the basic passenger version of IL-96-300 is distinguished by its extended 9.6 m fuselage, an increase of 20 tonnes maximum take-off weight (270 tons) and more powerful engines PS-90A1.

    It was built four such aircraft, three of which were operated until 2013 the airline "Polet" has ceased its activities. Two of the existing board of this type is converted to an air control point Il-96-400VPU first ready. Two more aircraft will be converted into tankers Il-96-400TZ.

    According Velmozhkina, the contract for this work with the Ministry of Defence has already been signed. "But the question is still at the stage of presentation of evidence that IL-96 can be used as a tanker," - he explained.

    For the passenger version, some components of the IL-96-400 will be upgraded, but the aircraft to maintain the current PS-90 engines. At the same time discusses the use of this modification of the new PD-14 engine, which is designed for single-aisle aircraft MS-21.

    Representatives of "Ilyushin" say the fuel efficiency that four-engine plane will be at the western analogues. Make of IL-96 twin-engine car will be if Russia will be developed by the engine thrust of 32-35 tons, the company stressed.

    As previously stated by representatives of the United Aircraft Corporation (UAC), in the development plans of the family PD-14 is the creation of a traction engine, but the timing of its development has not yet been determined.

    What this sensor behind radome ?

    https://img-fotki.yandex.ru/get/9065...d4ac1_XXXL.jpg

    The two in parallel seems to be MAWS but what is the one directly behind radome ?

    The foremost singular aperture is a MAWS, and the adjacent twin aperture is a LWR:

    From the picture it seems these MAWS covers the frontal 180 * of the aircraft there is no aperture at the rear side or underneath the fuselage .

    Does the picture cover all the placement areas or Su-35 does not cover 360 * bubble for aircraft ?

    How does single aperture differ from twin ?

    Underside of the stinger has an air-ground link antenna and the triangles on the stinger are RWR's.



    Since 2014 production the stinger flare boxes has been moved to the underside of the stinger.

    Pastel RWR sensors are on tail fins. I think triangles on the stinger are jammers.

    The Su-35S doesn't employ the 'Pastel'. It uses a more modern system designated L-150-35 and has much more advanced capabilities as an ELINT system (станции непосредственной радиотехнической разведки/СНРТР), than a mere RWR:

    https://www.google.co.jp/url?sa=t&so...uvUnO8xWBvJ0Ag

    A derivative (L-150-16M), marketed as an upgrade for Su-25SMs, even claims a capability to cue radar-guided AAMs:



    ...but I'm a tad sceptical on this last claim - even the mighty AN/ALR-94 needs the AN/APG-77 to cue radar homing AAMs!

    L-150 is Pastel the following number is modification for specific use on a plattform. Pastel RWR were since a few years advertized as being accurate enough to cue ARHM on the source of the radar when designated as a target (narrow beam).

    Laser warning receiver. Would be used to detect ground and air based laser targeting systems such as those from SAMs or laser range finders on aircraft.

    L-150-35 is most certainly NOT 'Pastel'. If the differences in the system components (pic in link above) aren't glaringly obvious, then GT this:

    Is that relevant on a fighter? I've always thought that fighters would be either too fast or too high to care about laser guided anything...

    Plenty of fighters use laser range-finders with their IRST.

    Pretty significant news for Sukhoi- the 100th SSJ has flown.

    http://bmpd.livejournal.com/1687161.html

    It is the 95th serial air-frame, and the first for the Irish airline CityJet.

    Agree with what hopsalot stated. Range finders are present on a lot of fighter aircraft these days and so the LWR provides another source of passive warning to the pilot. For the ground based scenario, there are a few SAM systems with primary or secondary laser range finding or guidance and at some stage these aircraft will fly low enough or slow enough to make this an issue.

    I'm not surprised to see this on the SU-35 as I thought I had seen a few previous Flanker variants with LWRs?

    OK.. that would mean that even IRST guidance is not entirely passive..

    I don't think any other Flanker variant had this.. Not even Chinese J-11s, AFAIK..

    Passive until the laser range finder is used at which point, if the target aircraft has an LWR (which is not many), it would be noticed. The range finders overcome the IRST ranging issue but typically don't have a range over 20-30kms.

    Just found it, the Malaysian Su-30MKM has a LWR from Avitronics in South Africa although they refer to it as a sensor not a receiver...

    For the Malaysian deal, Irkut was the main contractor, but canards, stabilizers and fins were manufactured by India’s HAL Nasik under a $25-30 million value subcontract, and India plays a role in helping the RMAF to maintain their fleet. The main difference between the MKI and MKM versions is the replacement of Indian and Israeli avionics, ECM (electronic counter-measures), and LITENING pods with Russian, French and South African equipment. This includes original Russian equipment, Thales of France’s HUD, NAVFLIR, and Damocles surveillance and targeting pod; Avitronics South Africa missile approach warning sensors and laser warning sensors. India’s SU-30MKI Mk3 is also be equipped with an on-board mechanical health-and-usage monitoring system (HUMS) from South Africa’s Aerospace Monitoring And Systems (Pty) Ltd (AMS), but there is no announced word on whether the Malaysian SU-30MKMs are equipped with a similar system.

    With all the talk of extra Su-30SMs (certainly the airframe number will be higher than Su-35 before 2020) I sure hope they finally put LWR and MAWS on it...

    Riiiight.. Stand corrected... I have never noticed that the MKM actually had two sensor suites by Avitronics - the MAW-300 (UV based MAWS) and the LWS-310 (laser warning sensors against GaAs, NdYag, shifted NdYag and Erbium Glass lasers)

    I had to scratch-build them on my Su-30MKM model....... the MAWS is in a multi-facetted 'turret' on the upper spine, behind the airbrake...



    .... and on the underside in front of the nosewheel bay....



    Note also the forward-facing LWS-310 next to the MAWS - the rear-facing ones are on the intake sides.

    The finished model.......



    .... next to its Indian cousin.....

    Brilliant builds, Ken.

    Regarding the MKM in general, I must say that I wish the VVS/VKS had a squadron of Su-30's in that scheme. Not that there is anything wrong in particular with the Russian affinity for colorful things, au contraire, but that sleek grey "western-ness" does look good on a Flanker.

    Depend on contract, if those components will be included.

    I doubt they will put Avitronics on them if they haven't already.. and integrtaion of the domestic LWS and MAWS found on the Su-35S would be quite costly..

    One died on the spot, one died two months later (75% burns...) and 3-4 didnt get any injuries apparently.

    R.I.P. to the deceased... But, pardon me for sounding insensitive but this was a rather bizarre incident - a positively massive engine failure - and that's the most"interesting" part if you will. The mighty NK-12 has proven itself incredibly reliable over its 50+ years of service, so what exactly was the cause of this apparent cascade of sudden failures? Engine suddenly blows up (?!), fuel tanks are ruptured and boom - you got yourself a fireball. Horrific to say the least... I do want to see the results of the investigation though... That kind of thing just doesn't happen from out of nowhere.
