Nice... With AAM R-74M2 and ARM Kh-58UShK models.

P.S.

On that video from 0:07 we can see that there is very little space between the radome's top of the Kh-58UShK which is 4.2 long and the wall of the FWC. So FWC's lenght is about 4.2m .

 
Question is would two such missiles (650 kg per missile) in the rear bays mess with the trim and perhaps cause a lot of trim induced drag?
1300 kg is probaby doable in absolute terms and still have the plane usable. but makes one wonder what is the useful limit for su57, when it comes to total weight carried in the rear weapon bay. Would 2 tons be too much for example?
 
I wish they would've gone with a different livery though, as it's not a combat duty jet there is an opportunity to go crazy with the liveries.

Think Su-47 livery, or make it silver with soviet roundels like an old school cold war fighter, give it the T-50-3 S-70 camo to advertise the upcoming production models of the UCAV, a Tu-160 style all-white with accents in red and blue would also be great. I think the digital camouflage is fine on the production models, but for the airshow machines a bit more spice could be in order, as they're more or less simply meant to draw in crowds and put on displays for potential customers.

Kh58ushke
Weight 650 kg
4.19 m long
0.4 x 0.4 m wide
149 kg warhead
Speed 4200 kmh
Range 245

JSM
Weight 420 kg
4 m long
0.5 x 0.5 m wide (approx)
120 kg warhead
Speed 950 kmh
Range 550 km (approx)

Aargm ER
Weight 467 kg
4 m long
0.3 m x 0.35 m wide
(Though that doesn't include fins which don't seem to fold??)
Warhead maybe 68 kg
Speed likely 3000 to 4000 kmh
Range likely over 300 km

3 missiles listed are not the same role of course. But aargm can be used against fixed non emitting targets. its not hard to imagine that kh58ushke may get a different seeker, at least a satnav receiver.

It certainly packs a lot of punch and weight in a compact form. sure, it may fall behind other missiles to some degree, but only in some areas.

And su57 may be able to carry 4 internally. Twice as many weapons as f35. Thats not insignificant.

one thing i don´t get it... the windshield does not apper to have coating applied, just the second part of the canopy. I know this is just a prototype, but the production models are the same way. Isn´t it supposed to have all the canopy coated like other fifth gens? Otherwise the radar waves will enter the cockpit and will increase the rcs. Is that correct?

What that what-if for? Meaning? Do you think Sukhoi is tracking your wishes? (No, it doesn't). Next guy will come wishing it would be pink. This is not what-if thread.

All Su-57 have an ITO coated canopy.

Certainly not, the acquisition of such a machine is sadly a bit outside of my budget. As such is the customization as well (it would be midnight purple with tan leather seat, ambient lighting, black rims).

That unfortunate fact aside, one just has to look at the Russian Knights to see that there is space for interesting liveries on Russian air show assets. Meaning, I personally believe that the recent repaint was a missed opportunity. They could have even gone for desert theme as on the Algerian Su-34MEs, potential Middle Eastern customers in mind.

Air shows have two purposes, publicity and sales. And usually a bit of visual spice is a welcome tool in the box for both of these criteria. A fresh visual appearance wakes interest and it's a great way for UAC to advertise their product. Solo display, aerobatics teams and factory backed flight demos often have unique liveries specifically for marketability. So while it's in large part simply aesthetic preference, as in I'd be happy to see additional liveries on a gorgeous aircraft, it also has real world value beyond my own, obviously fundamentally important and definitely very influential, opinion.

UVKU-50U ( height 200mm, weight 117kg) ,as mentioned earlier has max carrying weight of 750kg.

Now as we could see opened FWC (fuselage weapon compartment) doors and UFWC (underfuselage weapon compartment) doors,one of the crucial questions can be the next one : What is the Mach number and G-load limit for the opening all of them?

from the top of my head and I'm absolutely not sure about it but I remember reading mach 1.6 somewhere

Thrust vectoring can/does probably automatically compensate for trim without much drag or propulsive loss.

There are two new versions of ARM type Kh-58U , Kh-58UShK(E) with inertial and passive radar guidance.

There is also Kh-58UShK-TP/IIR (E) with inertial and combined passive radar and IR guidance.

Of course Su-57 can carry four of them inside of both FWC's.
