    Any reason for the GTDE starter or the APU unit running just before the aircraft take-off?? From pictures posted it looks the white smoke is cooming out of some engine upper fairing vents, I`d suggest engine lubrication system doing automatically oil drainage and depresurrization. Should be normal during engine operation, but not good if it is doing too often what would indicate problems meaning higher engine oil consumption.
    When studying T-50 in-flight pictures I noticed interesting details, perhaps indicating wear regarding GTDE exhaust doors, some might find interesting. What is going on there anyway, anyone noticed?

    I’m surprised no-one has mentioned the smoke emanating from bort 52 as he began his display at the 100th anniversary show last weekend.

    I took these on the Friday – there was quite a bit of smoke coming from the area of the upper engine as he positioned on the runway…..

    I didn’t see the takeoff on Sunday – but the display was ‘normal’ – but again rather sedate.

    Ken

    I watched the transmission live through the internet on sunday and noticed the smoke raising from upper engine fairings as well, do not know whats been evaporating there, perhaps some kind of preservation oil, though interesting.

    I can’t think how one would get the impression that the purpose of that display was to demonstrate any performance limits.

    He is being sarcastic, I`d have been as well, bcs the T-50 didn`t perform flying display, just turning circles with the Mig-29 which was a bit disappointing after MAKS2011 display, was that the purpose? I watched sunday transmission only.

    That is how I read it, smart thing to do really if that is the case. To have a multiplicity of variations in burn times, heats, intensities etc makes it pretty hard to pick out the target from such clutter

    Sounds like an excuse for above mentioned statement

    Having intel on an opponents hardware is always important and a two way street.

    Considering the fact they found out their sidewinders are not usefull during desert storm 1991 against soviet built flares, I wonder what they were doing when running so many classified military airplane programs testing and evaluating ex-soviet aircraft technology at Area51.:rolleyes:
    Instead of raving how smart russians were making flares with intentionally variable burn times, heats and intensities(wonder why/how would they do that in a spontaneously burning thermic compound), one can read on the internet that Iraqi Mig-25 equipped with the KDS-155 flare dispenser was using the PPI-50 flares, a steel can with a diameter 50mm, 850g thermic compound, burning at temperature 2000 deg C from 5-9sec, but with 4 times higher IR intensity than smaller PPI-26 (only 86g thermic compound) used on Mig-29 for example. These flares were used to protect heavy airlifters during Afghan war as those smaller KDS-23 were found insufficient against US stingers. Well, that`s why Aim-9P loved so much russian flares, mystery solved…

    Both aircraft seemed to have that strange intermittent “clicking” sound – what’s SOS-3?

    no, no just the Fulcrum, check 1:58 for example,
    http://www.sci.fi/~fta/MiG-29-2.htm
    The SOS-3 stall/limiter system allows for unrestricted use of high AOA which is automatically combined with a roll/yaw limiter a graduated 17 kg. (38 lbs.) stick-force inducer.

    thats pretty much why Ethiopian Flankers pounded Eritrean Fulcrums in their derriers. They caught them retreating turning back to base due to bingo fuel. But now Eritrea has Flankers as well.

    well, you see Ethiopian pilots were cowards, shooting down short-legged Migs leaving the fight without fuel….:D

    The same as Bulgarian.

    http://www.fencecheck.com/content/index.php?title=Poland%92s_MiG-29s_-_A_Visit_to_23.Blot_-_1.elt_Minsk

    And we should consider that both, Bulgarian and Polish Mig-29 version are degraded basic 9-12.
    Polish Migs have 10% reduction in thrust. Those are the same German Mig-29 that were used i many international DACT exercises with great success in WVR fights. Just imagine what could russian version of the plane do 😀

    Ahh, that`s not correct, nothing was degraded there, RD-33 thrust can be downtuned by operating a switch inside the left MLG bay on all built Fulcrums.
    BTW. Most of ex-german Migs-29 have been already phased out in Polish AF due to their poor technical conditions, wear, difficult serviceability urgently needing comprehensive general overhaul at WZL2 plant. Ex-german Migs were probably the first in the world(Mig-29 users) switching to on-condition maintenance concept during nineties(MAPO MiG supervising), therefore not performing prescribed overhauls what we all Mig-29 users know suit them best to keep them in the best shape.;) Polish AF decided to keep Migs those delivered from Czech republic and their own.

    The Polish air force operates both F-16 and MiG-29, I wonder what’s their opinion on the matter?

    http://www.youtube.com/watch?v=6DfkrYJdgAo

    This video is pretty self-explaining, the Viper pilot wildly checking his six o`clock the whole engagement time with the Mig always circling around his ass. Mig pilot with Darth Vader’s calmness and coldness, but sometimes pulling too much as you can hear the SOS-3 clicking sound, killing the F-16 several times just by looking at it. Then suddenly Viper pilot is cheering for something, LOL. I think it is bcs Mig pilot yelled over the radio Bingo fuel. :D:D:D

    :confused:

    Same engine? Link-1, Link-2

    PS: Link-1 Link-2, Link-3

    Geez, I spent several hours searching those dvds in my house, making those screenshots and feeling great 😡 how disrespectful you are just quoting youtube after that, you should be ashamed….:D:D:D

    anyway, thanks for posting them….

    Was it still a ‘nozzle technology mockup’ in 2005 as it was in 2003?

    Well, if you remember the 2003 static display, next to the Su-27 595 was a big screen showing the SALUT video presentation of the Al-31F engine test stend/then Su-27 595 with the multi-axis TVC nozzle installed. The same nozzle design lacking those three actuator fairings, performing ground tests with working TVC, therefore I`d not call it a “nozzle technology mockup” at all…;) Funny, that almost ten years old DVD with my burned MAKS2003 videos still works….:D Sorry for quality though.
    BTW. The video ended with a Su-27 taking off at night with full reheat, pity I cant recognize whether it is the 595.

    some say here that 595 didn’t ever fly with these KLIVT nozzles…

    it seems, it flew at MAkS2005. Never noticed before that they`ve changed wingtips.

    Second photo might be from 2011, it is the other LII Su-27 ACE 05 (ex 24-05) but judging by its appearance, not flown a long time.

    By “shiny”, Flateric beeing ironic;)

    Ken, your pics are great.
    They looks a bit cropped.
    If you used a 400mm lense, how much did you cropp em?

    Ahh, well I think 2003 sunday weekend weather was definitely better than 2009. I`m currently not at home, have no originals here but only resized down pictures from my 40D camera. These are just resized down from original resolution.

    you yet to remember ‘shiny’ MAKS-2003

    In what meaning “shiny”? As I remember Maks2003 Thursday they even cancelled the show due to heavy rain, my friend go busted and investigated by FSB ,bcs he was “suppossedly” taking pictures of military buildings, then I had to prove to a FSB guy that he is not from Chechnya (he looks like one of them by the way, brown eyes and hairs, sunburnt, hairy legs :D) as we left our documents at hotel due to embassy demands. Weekend was not shinny as well, but all over a great trip and adventure.:rolleyes::D

    BTW. what happened to these LII Su-27 equipped with vectored thrust engine from SALUT, never seen them flying a display?

    Martinez, good luck carrying that thing around your neck all day:D:D
    Can i make do with an 300mm Tele lense?

    I`m used to it, always wearing three cameras on my neck, wide, tele and supertelelens…:D The 300mm lens is enough, but definitely has to go on the other runway side, there you can make much better pictures. In 2009, I picked all three days in Zhukovski with rainy weather. 🙁
