Sukhoi PAK-FA / FGFA: Updates,News & Discussions

@PARIKRAMA

Thx for the post. Excellent comparison.

Looking forward to seeing the new 5+ generation PAKFA engine next year. It's lift/drag and speed/acceleration will have huge effect on its capabilities.

Thanks for tag.
Wonderful posts, Sir. Made for very enjoyable and informative reading. Thank you.

The start all and end of it all for the Americanos is BVR and be sure there is a black project in the US for higher everything BVR requirements. So if we take it at face value the stealth values for the Pak-Fa is a big crack in the armor, yea I understand the counter measures but lets say a Pak-Fa can counter X no of missiles but can be detected early on where as the F22 does not need to counter anything till it is detected.

Frankly the J20 in some aspects seems better in this front and keeping in mind the size of that plane its not a small feat.

BVR is the future & planes that have human's as options.

Thank you for the tag and very info-graphic post .

Sir , the radar is developed from N035 right ? So , it's performance almost doubled ? ( Both are having almost same T/R Modules , around 1500 ? )


Performance characteristics

"Air-to-Air" mode:

- detection range for targets with RCS=3m2 is 350 km

Scanning zone:
- in elevation: ± 60 deg.;
- in azimuth: ± 120 deg.

The number of detected and tracked targets is 30.

The number of simultaneously fired upon air targets is up to 8.

"Air-to-Ground" mode:
- mapping in SAR (synthetic aperture radar) mode with 3 meter resolution;
- real beam mapping in DBS mode (Doppler beam sharpening);
- ground moving target selection;
- tracking of up to four ground targets;
- tracking of one ground target preserving air sector surveillance.

There is always a point mooted that N036 is a AESA variant of Irbis E (N035) .

This implies the upgradation to AESA and additional performance parameters are surely built into N036.

Even though T/R module is still limited to 1555 main nose radar there are 2 secondary ones in the side with 358 modules.

So as a system with X and L band it works wonderfully.

Russia had been doing tests with 10W - 15W GaAS modules in the past while also been working on GaN modules as well that could be rated between 15W - 30W. The focus had been on reducing size and heat of the T/R modules so they could possibly fit more than the proposed 1500 and increase the number of modules in the same size.

But the best part is power supplied is same as N035 case of 20Kw.

The combination of X and L and side radars were not there as a system in N035 thus we see such drastic increase in performance.

Is that prototype # 6?

T-50 is truly a beautiful aircraft.

I believe it's the T-50-6, not to be confused with T-50-6-2.


Another picture: it's obvious which model this is by bort number:

What's the difference between T-50-6 and T-50-6-2?

I could not say, people say that it will have extensive changes to the airframe but the same thing has been said about every prototype and so far the changes, at least physically from what we have seen have been minor.

Russians looks like they are satisfied with overall design of T-50. Their designers and supercomputers did a great job.

Is that R2D2 looking thing in front of the cockpit going to be gone on the final version?

That is the IRST/OLS, why would they remove it? Unless they wanted to save money there is no reason to remove it.
