    I hope they have them on those two pylons there.  In that photo I posted, it shows the furthest rear mounted R-27 and then there's another pylon forward of that for another missile which I didn't know existed until I saw that pic.  But you're right, having a catapult to safely toss them away from such a volatile area right between the engines would be a better idea, I would think.

    BTW, speaking of that R-27 tucked between the two engines, I found it fascinating that they would have one on there during one of their amazing acrobatic air shows.  If you look at this video, aside from the heart-stopping performance of the Su-35, why on earth is there an R-27 mounted on that one rear pylon between the engines during an airshow?! I'm guessing the missile is almost certainly inert?  Even so, any idea if there's a reason for that?

    You can clearly see it right at minute 0:36 of this video.

    The centreline pylons are normally for carrying R-27s... the early model Su-27s could not carry fuel tanks or weapon pods so the centreline and inner wing and under engine pylons were all intended for the R-27 with the outer 6 pylons (two wing plus one wing tip on each side) were for R-73s.

    And expert would notice the two outer wing missiles are R-73s, but the other wing mounted missile and the engine nacelle mounted missiles are the smaller R-27, while the two missiles between the engines are the bigger R-27E missiles...

    VVS Air Force Videos - Page 4 Venecu10

    This is a Venezuelan aircraft I think based on the name of the image and has four R-73s on the outer wing pylons and four dumb iron bombs on twin bomb pylons and then the inner wing pylons are two Kh-31s, with two R-27 missiles on the engine nacelles, while down the centreline there are two R-77 missiles mounted singly on each of the two pylons located there.

    The pylons for the R-77 have a pneumatic arm to push the missile clear of the aircraft cleanly.

    That's pretty cool, and what a friggin weapon's load!  Looks like those center line pylons are fine for R=77s an R-27s as well which makes it quite versatile.

    But did you notice the video and the one R-27 in the same place as the pic I posted a couple of posts ago?  Why during an airshow?  What do you think?  Is there a purpose for that or it probably just happened and is it inert or active?  Could it be a smoker?  Never seem those act as smokers and not the right place anyway.  Plus it's not only this video, I've seen it in several airshows which means it's for a reason.

    Another question I have for anyone who might know - any idea why all the MiG-29s/35s. Su-27s, some Su-30s, Su-34 and Su-35s have the top front of the nose fuselage right in front of the canopy painted black?  Is that an anti-glare reason?

    See that area on a lot of the models painted black and trying to figure out the purpose.

Plus it's not only this video, I've seen it in several airshows which means it's for a reason..

    Actual operational Su-27s often operate with wing tip R-73s and centreline R-27s... the wing tip and centreline positions are low drag as they don't have pylons fitted which makes them lighter.

    Aircraft in Syria often have wing pylons fitted and missiles on their wings but rarely have full pylons as shown above...

    For an airshow sometimes they have smoke generators in the dummy missiles carried... again having wing tip mounted missiles emphasises the manouvers the aircraft performs and a smoke generator between the two engines creates a centreline line of smoke to show where the aircraft is moving in terms of loops and lines and turns etc etc.


    That's pretty cool, and what a friggin weapon's load! Looks like those center line pylons are fine for R=77s an R-27s as well which makes it quite versatile.

    As mentioned the R-77 is relatively new to the Russian Air Force and recently a twin mount has been seen on the centreline of the Su-35 I think... so four R-77s between the engine nacelles... a boost in weapon potential.


    See that area on a lot of the models painted black and trying to figure out the purpose.

    Same reason some sports players put black paint under their eyes... reduces glare when looking towards lights or sunlight...

    Western cockpits are generally black for the same reasons but Soviet and Russian cockpits are pale green to reduce glare but also make the cockpit lighter and easier to see in lower light levels...
