Sukhoi Su-57 flight testing, development & operations [2012-current]

[QuadroFX]

Aren't airframes from T-60-6-2 onwards already considered "Stage 2"? Have they redefined the second stage?

It is about second stage equipment(avionics. engines, et cetera.), not the airframe. Both first and second(?) stage Su-57 have second stage airframe.

BTW Paralay, what's your estimate on the internal fuel capacity of Su-57 ?

TW Paralay, what's your estimate on the internal fuel capacity of Su-57 ?

I will forward your question to Paralay .

 

[stealthflanker]

Eh... sorry i thought your were Paralay yourself :x.

and Thanks, he answered in forum.

[haavarla]

Soo, do we have a picture of the new wet bags on Su-57?

Paralay must have developed a natural stealth/spoofing ability as a result of studying these aircraft for so long!

 

[paralay]

BTW Paralay, what's your estimate on the internal fuel capacity of Su-57 ?

Internal fuel capacity 11000 - 11500 kg.
This may be along with the fuel tanks in the weapon bay 11500 kg - 2 x 1400 kg = 8700 kg

I always amazed by Su-57's cheek radar array. Well It might not be the first idea as the F-22 was planned to have one but it's Su-57 actually brought the concept into flying stage. Performance wise tho it would have about 30% of the range of the main nose array, it would be about 130 km vs 3 sqm.

These aircraft have a lot of engine exposed, does that raise the infra red signature markedly?

To a degree. Tho most of that "steel tube" is covered on later airframes, leaving only nozzle.

 

[Foo Fighter]

Thank you, Sir.

wheres the landing gears?

 

[flateric]

inside landing gear wells...

 

[stealthflanker]

It's taking off.

 

[Saber]

Guessing this is S-2, I'm very interested in the upper air intakes being different from each other.

It's always nice to have ambitious plans!

It's taking off.

yes i can see that.
what i mean is. isn't it usually a bit too low to already have its landing gears fully retracted? don't they usually retract a bit later?

for example

You expect this to be too ambitious?

1/month isn't exactly 'amibitious'.

In perspective to the past experience, the still unclear economic situation and the number of so far produced aircraft since years I rate 9.5 aircraft per year most ambitious.

Which airframe is this? No. 02?

 

[GARGEAN]

It's really not wise to rate aircraft production rates less than year after it entered serial...
Economic situation hardly matters too since contract is already finalized and included into GPV.

I know, nothing is written in stones, but please... if you look what was once promised, promised all the years and what is now promised, how likely is it that the promises now will be met, when none of the previous ones was accomplished in time?

 

[stealthflanker]

Well it's quite normal to retract gear as soon as you're no longer in contact with runaway. Whether it's done "bit later" is on pilot's judgement.

 

[GARGEAN]

Previous was "promised" by talking heads without any sensible basis (and sometimes not even that but just imagined by journos). This number is set in established contract.

And we know all military contracts run exactly on time......

 

[stealthflanker]

The important thing is that the 76 airframes. It will have to be fulfilled and paid for. If there is late delivery then we can see some class action suite or other law related news.

 

[GARGEAN]

And we know all military contracts run exactly on time......

It's not about running contract right on schedule, it's about running contract instead of talking words.
As for schedules: many delivery times for new airframes for VKS were fulfilled earlier than anticipated: Su-34, Ka-52 ect took deliveries ahead of yearly numbers.

The radome of the aircraft reminds me of Pyroceram.

By some special external attributes?

 

[BLACK_MAMBA]

Looking at those images they don't exactly scream 5th Gen do they? 5th Gen lite perhaps... The J-20 evolved significantly from the prototype stages where as it looks like the Su-57 has barely evolved at all except for a few sensors appearing here and there.

 

[QuadroFX]

Looking at those images they don't exactly scream 5th Gen do they?

How many AESA antennas J-20 and F-35 have? Does the F-35 have an active laser countermeasure system?

 

[GARGEAN]

No! Rivet counting is more important than intelligent analysis!

 

[stealthflanker]

The color. Oh and Pyroceram is a very sensible material for Radome especially if it's need to work on high temperature.
