… and it does have the same beefed-up stab…..
Ken
Thanks, it could be an improvement to the baseline Su-27 Flanker with 2 underwing hardpoints as well, a technical bulletin introduced during service life. They probably found out that with newer armament, missile exhaust gases might damage the stab alluminium skin. Solution was to add, beef up stab tips with titanium plates.
Yes, that’s what I was referring to but I’m still not sure. Curiously enough, I think these sleeves first appeared on variants with 3 underwing hardpoints, so they might be intended to protect the stabilator leading edge from erosion by missile exhaust, rather than provide additional strength…. .
Hmm, that`s interesting. I must confess, I noticed those sleeves at the Su-35BM at first, never have put things together as you did, thanks! I think this picture from Maks2007 could prove you right, you can actually see the routing of missile exhaust gases on the Su-34 stabilizator.

The one exception might be the horizontal tails, but I’m not certain whether the dark area isn’t just an enlarged version of the titanium (?) sleeve found on the tips of most Flanker-family stabilators.
Damn, you were right, those stabs sleeves looked suspicious to me years before. Just went through my pics from MAKS2009 again and look what I found. Geez, I noticed it right now that they`ve decided to beef up horiz. stab structure early on with some titanium plates. Perhaps too much loads, with the new built Su-35S we can see the final modification.

its no use.. arm chair experts know more than a mechanic who handled MiG-29s :diablo:
but I still keep trying……;)
good for you!
btw
are you friends with Flex297? he was a Slovakian fan of Russian aircraft.
I know that Flex is my country man, but do not think I have ever met him in person. I remember once many years ago to be in touch with a guy via email working with a team preparing the so called Mig-29 unveiled secret CD. Later on I had the impression he was Flex297, but I probably knew him under his real name only. Haven`t seen him writting for a long time.
If they increased the empty weight or used better alloys to increase the airframe life hours remains to be seen.
Soooo again, what the empty weight on this bird?
You probably wont see any figure telling you explicitly how much structure weight they`ve gained bcs it might already been spent on more equipment meaning increased capabilities. In any case, I`d call that “face lifting” rather than a deep modernization of the Flanker inner structure, probably wasn`t a need for that either or evaluated as a possible high risk. In my eyes, Flanker was and still is ahead of its time in some aspects of aircraft design and after 25 years of service still offering potential for improvements. The fast growing information technology, 3D CAD/CAM/CAE, computational methods for structural analysis and wide use of modern CNC machinery in the Sukhoi design bureau and production plants allowed them to redesign, optimalize and manufacture even more aircraft strenght critical components from titanium instead of the steel 30XGSA saving weight and space for more fuel and equipment. That`s basically all they did with the Su-35BM airframe, very less advanced materials, bonding or assembly techologies, no doubt all that prepared for the Su-50 only.
This is something new..:confused:
market with red circle, is it some MAW or RWR sensors?
The first one near the wing trailing edge is nothing unusual, it is the fuel tank drainage vent, also seen before. The second circle is probably comm or nav antenna.

Generally, it is always interesting to see an aircraft in a primer coat, bcs it reveals more about the skin structure and materials it is built from. The yellow appearance of the primer means presence of zinc-strontium chromates, a corrosion inhibitors covering only alluminium skin. Thus I have the feeling that no substantial changes have been made into the Super Flanker structure, so to speak it is almost the same “metal ingot” Su-27 from seventies. What do you think?

I wonder, have anyone seen pictures of the Black Eagle flying with landing gears retracted? Did they try that already?
MiG-29K IN SERVICE WITH INDIAN NAVY
In newer versions of Mig-29 such as Mig-2K/KUB and Mig-35/35D, the turbine starter’s exhausts are ejected upward so we don’t see any hole on the 2,150L belly drop tank. In the other hand, older version of Mig-29 like Indian Mig-29 still keep the old turbine starter’s exhaust system (downward) so they have to make a hole on the big belly tank 2,150L (no need for the 1,520L tank) for the exhaust ejection.
Finally the right answer, good find Kopyo! Now, some pics to see the new APU exhaust.
Yes martinez, it has been descussed before..
If my memories serves me right..
I remember seeing a clip of an Mig-29 fire up the APU from behand.You could clearly see the excaust coming down under the aricraft. It looked to me like the vent was placed much further aft between the two engine housing..:confused:The vid should be somewhere on this forum..
Sorry, but I do not remember discussing the exhaust of the new APU in the Mig-29KUB. Nevertheless, I remember discussion with you about the old GTDE-117, the APU of the baseline Mig-29A(9.12A)

did you mean this video I put on the web a year ago?

The APU air intake offset to port on newer versions (MiG-29K/MiG-29M have it on the starboard side), located at frame 7. The exhaust is now located on the fuselage underside near the starboard nacelle. It has a door to reduce drag when the APU is off.
Any chance you can backup your statement with a picture? I do not see the APU exhaust between the engine nacelles near frame 7 of the Mig-29KUB. I think you are mistaken it for the starboard front engine hinge (frame no. 7g-7d).
Just a theory . I think on the legacy Mig-29 that hole in the tanks ( the 1520l one and this 2150l one ) is for the APU exhaust.
I assume you saw that big tank without the hole on the Mig29K /Mig-35? That’s what i see in my pics , the new Fulcrums don’t seem to have the hole in the tank. Probably the APU exhaust has been relocated on the new ones ?:confused:
Good thinking, but where is the APU exhaust now?
Ken: no, it has not been discussed yet.
MiG-29UPG at LII 🙂

checking question
Note the black hole at the bottom side of the new 2150l fuel tank. I have also seen the same bulky 2150l fuel tank without the hole, why there are two versions, anyone?
Maks 2011 come up fast.
I’ve arranged visa, flight in and a residence.Whats the easiest way of getting from Moscow to Zhukovsky.
Bus, taxi or rent a car?When can we expect a more detailed program for all the days at MAKS 2011?
see my reply here….

Guys, I was wondering whether there is any information available on the J-20 regarding its longitudinal static margin expressed in a percentage of the MAC? Thanks
If I can’t even spot the joints on control surfaces, it’s very unlikely I can spot weapon bay joint/slot on the same photo right? Regarding photo quality and/or engineering level.
Actually the aircraft shape and quality of surfaces looks very good!
Sorry, didn;t know you are poking fun at someone else. The black surface looks tidied up by some kind of denoise software, doing that my self for my photos as well. 😉 Therefore you are not able to see any fuselage panels or other joints on your picture above. Otherwise it would mean that Chinese built first stealth prototype with surface skin superior to the F-22 Raptor… :diablo:
Same logic…
on those bottom view photos I can’t even see a single slot on elevon/flaps joints…damn that means J-20 doesn’t have any working elevon/flaps:diablo:Actually I think this is some kind of conductive rubber seal on joints, maybe on weapon bays too?
perhaps it is because the picture has been denoised heavily thus loosing detail information…
