First time I have ever seen one with external tanks, wonder if they are testing them. I mean where are they flying the thing that it needs another 1200 gallons of fuel ontop of the 3300 gallons it already has internally. :shrug:

Nah.. it's just testing the back-up coal-fired power plant.

Russia is big. From plant, where it's produced, to Moscow, where it preliminary testing, 6000 km (3700 miles).

Some of their birds have great range, no question. What often goes unmentioned though, is that that amount of internal fuel sloshing around may give it sluggish behavior in WVR dogfights. I never see this mentioned.

Can Flankers pull off their vaunted "super-maneuverability" will full internal tanks? Nobody has answered that question to my satisfaction, anyway. Would love to hear your best guesses though. Here's mine...

SU-27? Probably not
SU-30SM? Going to be close
SU-33?? No way
SU-35? Best of the bunch, LOL

From the history of Su-27, it is known that in the terms of reference there were 2 options for fueling:
Main - 2500km range and 8g.
Full - 4000km range.
This allowed to simplify the design and provide the required range without the use of external tanks.

I read years ago in a book I can't find anywhere that if there is fuel in the forward tanks then the Su-27 is stable and has lower AoA and G limits. You often see a ~67% fuel load considered "Standard" even for normal take off numbers. This implies to me that the lower fuel load allows it to take off in an unrestricted profile, while filling the "internal drop tank" if you will leaves the FCS restricted until the fuel is burned off. This same book is where I first read about the FBW of the Su-27 and how it could be overridden. These were things I read in the 1990s that I never saw properly documented again.

Some of those airshow Flankers (Su-27) from the 1990's are "stripped down" (hence made a few thousand lbs lighter) such as this one:

The specially colored birds with pilot Anatoly Kwotschur (Kvotchur).


GTA4 and another poster on this site have proved this recently. I was unaware of the jet being lighter than a standard squadron jet until they informed me as so-


Watch the Ukrainian Flanker demos and compare them to the Kvotchur ones, and you will see a difference. The jet is not as agile.


I'll try to post more later, but I am currently at work.

G limit of Su-27 with full internal tank is 6G.

You can see some more photos of them here:

Stripped down airshow version of Flanker are very easy to recognize thanks to their white-red paint and the lack of IRST, underwing pylons, radar.

Eloise,

Thank you for that link on the Flanker. :D

Do you happen to know if the Russian Mig-29's that flew in the late 1980's-1990's air shows (like Farnborough or Paris) were stripped down or made lighter to any degree that the Flankers were?

T-15 Mission X

Distributed training with ground sims.
Fully simulated threats
Cockpit display looks a LOT like the F-35 (single panoramic display with "windows").

Its a ongoing F-16.net mystery with no straight answers that even I am left in a bind.( heavy sarcasm intensifies)

OLS-K is not a 360° passive infrared sensor like DAS, OLS-K is an underbody IRST with a single sensor, more like EOTS, while DAS has 6 sensors around the aircraft.

This sensor can detect, identify, and track multiple airborne targets simultaneously.[86] The 101KS-O infrared countermeasure system has sensors housed in turrets mounted on the dorsal spine and forward fuselage and uses laser-based countermeasures against heat-seeking missiles. The Atoll complex also includes the 101KS-U ultraviolet missile warning sensors and 101KS-N navigation and targeting pod."

Where exactly is it just UV based?.

101KS-V and 101KS-N have the same role as EOTS aka IRST and FLIR
101KS-O has the same role as ThNDR aka DIRCM.
The 101KS-U is UV based and has similar role as DAS aka MWS, but thanks to IIR, DAS can do others stuff as well.

101KS-O is laser DIRCM same as ThNDR. Purpose of each sensors are in my post above.
