Su-57 Stealth Fighter: News #6

How do you call the mini wing near the cockpit ? It seems different too.

The top glass cockpit is black. RAM coating on it or just manufacturing process ?

The little aeration hole on the back under the aileron is also different which was already made in different version on the prototypes.

The opaque glass is probably a type of adhesive film, coming from the factory and removed later. The HUD looks like the 2019 maks model ...

The aileron being down stopped any nosey cameras having a view up the inlet. As someone wrote somewhere, the CIA would have given someone's right arm for pictures like this 20-30 years ago.

Ca. 9:00 onwards, many great views of the production plane and info about Shoigu's visit:

LEVCON (Leading Edge Vortex Conditioner), though it works rather as a LE flap...

Izvestia says the first Su-57s will go to the 6th army of the air force in the Western military district:

"The export version of Russia’s Su-57 fifth-generation fighter will be on display for the first time at the Army-2020 international military and technical forum and the plane will also take part in the forum’s flight demonstration program, the press office of the state hi-tech corporation Rostec announced on Thursday.

"The Su-57E export version of the fifth-generation fighter will be demonstrated for the first time at the Army forum as part of its static show and will also take to the skies under the flight program," Rostec said."

This army expo makes me feel like a child that cant wait to open his Christmas presents. I hope for a wonderful display of some military projects that have not yet been revealed.

The thing flies and turns like a R/C scale model

Still no images of r77M and other air to air missiles ?

R-77M ? The Ramjet one ?

The one being developed for su-57 with 200km range. It's not a ramjet but dual pulse rocket motor.

Both nozzles

R-77PD is the ramjet model, R-77M is the new solid rocket missile to replace the R-77-1 currently standard service with 110km range.

R-77M is supposed to offer double the range.

Nice saw tooth engine exhausts in that image below the one with the Kh-35 and Kh-38 Wilhelm... (post 286)

The question is whether those nozzles mean izd. 30 or can they be installed on existing izd. 117? Showing them on a plane which should be the export version gives a hint that they could opt for the second option IMHO.

Manufacturing seems much improved. Let us see whether they will be capable of significantly improving Su-57's radars detection ranges of opposing stealth aircraft.
Improved missiles are making it more difficult for fighters to dodge them.
Su-57 concept of dodging an opponent first spot first fire missile and then outmaneuvering the opponent aircraft in a dogfight is becoming difficult. It is no longer mig-21 vs f-4.

You talk as if Western Internet Bubble and their condescending anti Su-57 drivel was right to start with... such technical limitations and hopeless operational concepts derived from them only exist in the minds of some guys that have no clue and worse no interest on how Russian military (or for that matter, any other) actually work...

Note the deliberate angle of the engines and their spacing. This ain't no F-15. The use of two engines is leveraged to the max
for maneuverability.

AA missiles have limitations and maneuverability is actually worth something. It is not for dog fights only.

No, it doesn't. It simply shows that part of the outline of the exhaust duct can be seen through the intakes at a viewing angle off the central axis. Where are the compressor blades located when the engine is installed?

The Su-57 ducts are not serpentine like the F-22 (because that introduces too many performance compromises) but this constant BS about her blades being visible in the frontal aspect is just nonsense.

Only if the radar is located above the plane of the jet. For any ground radar they are invisible. As for being detected in
the air by other jets, that was never the objective of stealth.

Isn't the radar blocker already part of the plan from the day 1 of Su-57's inception ?

I would think if they developed stealthy sawtooth engine nozzles that they could fit them to either engine... as both would probably benefit wouldn't they?

They are still called missiles for a reason... the PK against an aware enemy with modern sophisticated EW equipment is going to be pretty low, and with stealthy enemies not really carrying that many missiles to begin with it will often come down to a gun fight... where good manouver performance becomes important.

The 9M100 missile is intended to be an anti missile missile too so even if you can't jam them having a bundle of 6-10 anti missile missiles could render the F-35 or F-22 unarmed when they get close...

They always mentioned blockers as being a thing because S shaped intakes are shit.

The Su-35 and MiG-35 have mesh screens that are raised during takeoffs and landings to prevent large stones and foreign objects entering the air intakes and damaging the engines... I would think similar screens further back could be used to maximise internal reflection of radar waves entering the intakes.

The RAM coatings inside the intakes will chip the strength of the radar returns with each bounce...

Edit: I should also say yes... AFAIK radar blockers were part of the plan for the Su-57s...
