I'm glad you figured it out but why do you need to see the runway anyway? Both Sukhoi and MiG have lots of good looking gauges...

God must be wrong...

^^^^ Pause game key?

That's why I drink fast... Few years ago I placed a beer on top of a guitar amp head, few moments later I couldn't hear my self play anymore so I turned around to see WTF... beer that cost me somethin like US$1,000...

Who told you that?!!

You should face him and book him...

Yeah, I'm not certain 'bout zero / reduced gravity tests. Here's a better pic of it:

^^^^ About that Il-76 tail at Zhukovski... It simply sits in a hangar that's kinda too small for it! It's an aircraft used for various avionics and engine tests etc. It's literally called "flying laboratory". IIRC it was also used dor simulating zero gravity conditions during Buran programme.

^^^^ Amazing! I wish for it in future ED products!

I've never said that nor I thought that. The problem is not with OKB Sukhoi. Now take this for granted...you'll see no significant engine nacelle / intake changes until you see a new engine. And that's what's kinda disappointing. Current engines used with T-50 prototypes are uncapable of supercruise with "S-intake duct". Probably, 'cause if LM did it it would be in year 1997...

There's 4 T-50 prototypes so far and I saw no major structural or functional changes. All I see so far are changes of peripheral equipment that may or may not work in practice or combat. Sukhoi is jumping all over the place with "gadgets" and whatever they get funds for to install on prototype but still fail to produce a more important "basic" parts in order to enter 5th gen fighter club. It's really useless comparing differences of PAK-FA and "hopefully" final Su-50 product with differences of X-35 and F-35 cause X-35 had all the basics of F-35 ironed out in year 2000 when it made it's first flight... That's correct. I agree. For a single engined aircraft with dual intakes "S-Intake" as You call it was the only option. In fact XP-80A had it too! When we talk intake ducts Su-47 wasn't anything revolutionary, if You take a closer look You'll notice it's a '60s theory in practice here.

^^ Not wrong but very disappointing, for a low RCS fighter I expected better...

Sounds too complicated for the device in picture... This KV-101 or whatever optical sideview looking tracker we see on latest T-50-04 is nothing but average Joe's garage security camera that costs 50$ and ships worldwide in 24hours...

^^^^ That sounds too complicated...

I've seen better homemade cockpits...

^^^^ It's a 2009 artist impression.

Could also be some kind of optical or IR sensor or ground mapping device...

It's a "rear view mirror", looks no better than ordinary camera feeding MFDs with real time picture of 3 and 9o'clock view.

Don't know if Yefim knows that there was LL-UV KS (круглое сопло=rounded nozzle) development taking place at Saturn Buerau but at the same time but LL-UV PS (плоско сопло=flat exhaust) was tested by OKB Sukhoi? Saturn's 2D TVC KS was first finished and fitted to (IIRC) Test pilot's #595 aircraft and it was first airborne. It kinda remided me of F-15 ACTIVE. Sukhoi's PS flat nozzle development was supervised by Pogosyan himself. It was a F-15MTD look alike. I don't remember any reports of reduced heat signature with this boxy installation but it could probably act as a thrust reverser for STOL. Anyway it was too bulky and complex. It also deformed aircraft's weight center point and finally abandoned in favor of Saturn's KS.

Yeah, very likely! However, here's the (@1:50)

Let's wait and see, I can hardly believe that KnAAPO knows the final result!

That's Clint Eastwood!

Guys, back in late '70s we had 14 prototypes of T-10 (Su-27) before T-10-15 which was the first aircraft with AL-31 engine that became serial engine of later Su-27. So have a little faith with PAK-FA...we just reached No4. However, what do you expect to see on a PAK-FA? Stealthy jet pipes? Why? Business end of PAK-FA looks stealthy enough so far and that's what really matters.

The aircraft in picture was a Lyulka AL-31F-M1 testbed, it's only purpose was 2D TVC testing. No significant IR sig reduction was recorded nor targeted. Development and logic of 2D TVC started about the same time in both western and eastern parts of the world, hence the analogues and similarities. F-22 engine development had more resources (read dollars) as usual so it's engines were prefected to a serial production standard while AL-31F-M1 system turned out "too bulky", complex and expensive and was ruled out in favor of later 2D "de Laval" nozzle of Lyulka AL-31P as seen on T-10M-11 or if you wish Su-37 "Terminator".

^^^^ Yes, FLCS can make my wardrobe fly... Trouble with T-50 (and previous Russian designs) is absence of such system that's reliable enough to be cleared for production so airframe and wing shape is the most important part of designing an aircraft in Russia. Sukhoi and MiG buerau first of all design unstable gliders before they introduce it to it's engines... So closing the space betveen T-50 engines is IMO very unlikely as it would reduce a lot of lift. Not to mention airflow used for engine nacelle cooling...
