Makes one wonder why such pictures are released, I guess its at least semi official.
Is the distance between the engine face and the inlet known? Maybe approximately? Placing a radar blocker there should be quite challenging, at least the blocker will be quite near to the inlet.

Take a look at X-32.
So you think that what we see is not the engine face but a radar blocker? Sure?
Would be the first "stealth" aircraft with direct visibility the engine face.
Well, nobody can really agree on just what is seen in this pic (for starters, the vanes seen in the intake are in the wrong place for the engine face if we take perspective and engine slanting into account), but what can be said is that we couldn't really jump to conclusions from a pure airframe testbed that is T-50-1. 50-2 and 50-3 airframes down the pipe might bring significant revisions to many of the systems.
from an old post by Khathi
Okay, guys, insiders have spoken at Paralay's forum, and that's what they say:
* This is T-50-1, it's leaked and someone's head's gonna roll (there was another photo with bay doors opened, but it didn't spread)
* What we see is indeed the engine front: as I suspected, for the airframe testing it was decided to drop the engine shielding completely
* The configuration is nowhere close to the final, and will be changed, perhaps rather dramatically, including the shape of a duct
* The radar blocker will be installed into the intake, which is NOT the fan-like contraption we often see, but a 3D coaxial labyrinth
* The radar blocker is already designed and produced, but now is installed only on T-50-KNS, and is absent on the T-50-1
* The radar blocker significantly alters the airflow in the inlet duct and current engines on T-50-1 aren't optimized for it => power drop
* That's why it isn't installed on the airworthy prototype, which suggests that it still uses older 117S engines
As for me, I still doubt that it's the engine we're seeing -- this means that engines must be canted in their cowlings basically the other way, essentially making the nozzle S-bent. Although that might be an ingenious solution of masking the engine's rear aspect.
Russian-Indian work on 5G fighter to go ahead without extra deal
http://en.rian.ru/mlitary_news/20100611/159390947.htmlRussian aircraft holding Sukhoi has no plans to sign additional agreements creating a joint venture with its Indian partners in the production of a fifth-generation fighter, the general director said on Friday.
Russian Sukhoi holding and Indian Hindustan Aeronautics Limited (HAL) agreed in early 2010 to jointly develop a fifth-generation stealth fighter jet.
Sukhoi head Mikhail Pogosyan had said that an additional agreement would be signed specifying the Indian role in the project, but on Friday he said that the Russian company hoped work would begin soon without any such deal.
"We don't plan to sign a joint venture. We have agreed on joint work with our Indian colleagues," Pogosyan said.
He said the joint work could be carried out under the current agreement.
"We will do our part of the work, our Indian counterparts theirs," Pogosyan said. "At the initial stage it is not necessary to have a joint venture."
Earlier, HAL was reported to be seeking a 25% share in design and development in the project.
Russia has been developing its fifth-generation fighter since the 1990s. The current prototype, known as the T-50, was designed by the Sukhoi design bureau and built at a plant in Komsomolsk-on-Amur, in Russia's Far East.
Russian officials have already hailed the fighter as "a unique warplane" that combines the capabilities of an air superiority fighter and attack aircraft.
Agreed, nobody knows what changes might come. Still its surprising to see something like that, at least it tells you that the Pak-Fa is or might be quite for away from its final looks. All those changes will need time, lots of it.

Thx, for that quote CaptMorgan. Interesting...
If it's the radar blocker, then the intake channel geometry is anyone's guess. If it's the engine face, then it's pretty difficult to explain what's it doing so close and how can you reconcile it's with geometry of the engine pylons.
In other words, nobody really knows one damn bit.
Is it really that close? Its hard to tell due to the perspective and the bad light, however the distance could be up to 1 meter form the inlet to the engine face. At least thats my impression.
MiG decline was on my opinion related to the fact that its main product specialization was always the "frontovny" fighter: as in Soviet military it was by long the main military aircraft MiG get a (well founded) preminence over others design bureaus.
When the Cold war ended, however it was the whole concept of a frontal aviation fighter, that went in a deep crisis
The mig-29s (and its predecessors) are not multirole fighters, but are instead a kind of specialized air-to air light aircraft with limited autonomy and payload intended to operate closely to the front line in order to protect mobile army formations.
When Russia decided to retire all single engine tactical aircraft and adopt an orgaization similar to the western one, the heavy Sukoi 27 proved to be a platform with enought flexibility to be developed into both the air-sup. than into the multirole fighter missions (and being exported), the light mig-29 failed both.
Obviously there were also political and economical interest behind the Sukhoi preminence, as always in the world, but i still think that these development has definitely precise tecnixcal reasons behind it.
1 meter from the inlet is VERY close. Remember, T-50 is almost the same size as Su-27, and that bird is ENORMOUS. Just to give you the basic point, the main wheels on T-50 are just a bit bigger than 1 m in diameter.
I posted a while ago a Boeing idea that allows to make shorter supersonic inlets. Their idea may also produce stealthier inlets easier. Interesting, it revolves around to similar concepts such as radar blocker labyrinths. Give a look.

It may be possible that Sukhoi engineers found a similar solution and simply is not installed in the PakFa yet.
looks like s-shape to me:
There is some bend, that's for sure, but note that the plane when is in ground is a bit 'head down' and it appears that the curvature is greater.
