Why not put em in T-50 LE flaps?
Perhaps if they angled them within the LEVCON that would afford a greater field of IFF coverage – to encompass that of the X-band side array radars.
For example, here the SIT-426 active E-scan IFF is fitted to the sides of the Raven AESA:

Oh really?! So, light enough to be placed in their entirety in the Su-35S’ LE flap:

…BUT (even despite the generational gap in fabrication – SoC/LTCC) – still too heavy for the T-50’s LEVCON. Hmmm……..
XTX-Horus, perhaps MadRat is correct. Most aerogels are radar transparent – thus facilitating RF transmission & reception (in this case for the AESA IFF).
The T-50-5’s original installation:


Must be having problems with the high-temperature polymer composites. Have reverted to all-titanium for the LEVCONS:

Some details on the Type 30 engine: compared to the 117 it has increased specific thrust (удельной тяга) by 5% (i.e. the increase in thrust for the same amount of airflow) and a specific weight saving of a whopping 25%.
More to come…
Would Signores Martinez and TomcatViP please check their PMs.
Berkut, why don’t you enlighten us as to what the B-1461 alloy is for?
Martinez, would you like me to show you what *progress* they’ve made?
Thanks Monsieur Paralay.
Those cowlings are certainly not PMC, more likely they are a new high-strength Aluminium-Lithium alloy known as B-1461 developed by VIAM:

Looks like they installed the side arrays too:

All those tax dollars going to waste…
She wouldn’t look out of place a century from now.
As any US senator will tell you, it’s about lobbying hard to spread the workshare and keeping his/her constituents happily employed in high-skill, relatively well paid jobs. Imho, that’s the reason LM & Co won the original ATF tender with the YF-22, as Northrop had already bagged the B-2.
Just a pity the work force spends a significant proportion of their wages on high-end Japanese & S.Korean consumer durables and the US economy doesn’t benefit from a full multiplier- but that’s another story.
Today, LM get to build the 3 variants of the F-35 for decades to come and NG get their fare share of the slice with the upcoming B-21 and 6G fighter.
The latter 2 are niche products which, incidentally, are what NG do best.
YF23 is a decades old design now, it won’t see the light of day in any way, shape or form..
…but yet to this day nobody has been able to replicate the design or even design features. The YF-23 remains the greatest fighter never built, an accolade that will stand the best part of yet another decade – until their 6G fighter breaks cover.
PMC?
Polymer Matrix Composites.

After automated placement of dry fibre tapes, completed wing and wingbox structure layups are processed using the Thermo Infusion Automated Center (TIAC), which reportedly enables very precise process control, including temperature uniformity of ±2°C up to 270°C/518°F and porosity levels of less than 0.5 percent.
Note how they’ve successfully upscaled the technology from the experimental to operational:


A World first and certainly the ‘bleeding edge’ of PMC production.
It makes the question mark glow different colours…
Here on page 5 of this very recent pdf, are details of the latest iteration of Phazotron’s AESA with LTCC T/R modules – probably destined for the MiG-35 and upgrade market:
The caption reads:
AESA radar with 3D-based broadband T/R modules, Multispectral Detection Systems, support, recognition and targeting
На базек ЛИиДБ в Жуковском 5-10 мая будут проведены частотные испытания с доработанными килями,..
Oh! so he was talking about [engine] vibration tests after all, how nice….which means “structural changes” compared to the Stage 1s (particularly those ‘under the skin’) are significant.
Barring any glitches, T-50-6-2 will conduct several safety certification flights before transfer to Zhukovsky. It is possible keen spotters are/have been lying in wait for these.
Personally, I would expect official pics to appear here sometime next week:
