I’m pretty confident, that due the size of the plane, and the 15TM projected engines, this pakfa thing will achieve the design goals

Of course the goals will be greatly surpassed when the new engine arrives

It will no doubt have acceptable performance, but it’s not going to realize its potential, until the definitive engines are available. If these transition engines were just fine, then why would they go to the trouble of building entirely new engines?

The Su-27 has achieved better supersonic ranges on proved and verified testing than the F-22’s claimed supercruiser performance, with an older Al-31 variant, no internal bomb bay, and outdated aerodynamics and engine control, will it use AB sometimes?, will it be on dry power constantly?, really is not important to me, to me the final result is the important one, BTW, supercruiser was defined in the mid 70’s for the ATF program, way before the stealth requirements were discussed, so your IR signature tale won’t work on me 🙂

I’m gonna raise the BS flag here. How far and fast has an Su-27 flown, especially with 8 AAMs? Cite your source.

This plane will achieve it goals.

The plane will likely meet the standards for IOC, but if the goal is to supercruise as fast and far as an F-22, then it’s highly doubtful that engines in the P&W/GE -132/232 thrust class will accomplish this task.

It’s been posted on here numerous times. I’m guessing the search function works as well on your computer as mine. 😎

I’ve used the same figure, since the Russian links gave it, quoting Pogosyan himself.

Early last month Sukhoy General Director Mikhail Pogosyan said the PAK FA would be commissioned with ‘first phase’ engines, and ‘second phase’ ones would require another 10-12 years of development.

Speaking of aerodynamic superiority- unless these control surfaces allow the T-50 to cruise faster/more efficiently, have a higher ITR/STR, then I’d say it’s a pretty subjective claim. How much more care free does the F-22’s handling need to be(it already has basically no AoA restrictions)?

Su-27 came a few years after F-15 and edged out F-15,

To be more precise, the Su-27 out edges the F-15 in certain parts of the flight envelope. To say that it out edges an F-15 as a weapon system is perhaps a bit of an exaggeration.

PAK-FA came a few more years after F-22 and will have the edge, hardly surprising.

I’m going to have to raise the BS flag on this statement. To claim this unequivocally, before a production variant even flies is asinine.

it will be more agile, only that. Is it better? yes in terms of agility but not at the overall combat capabilities, they will depend in other factors, but in performance and agility the T-50 is marginally better.

And this has been demonstrated when exactly?

Stealth is equal at frontal and side signature but not rear signature. the T-50 is similar from rear view to the F-35 in RCS signature

This would be based upon what? Eyeballing it?

Please do not make us believe that you could tell the difference between a prototype and a production plane of the same generation.

If you really can, then i am game, otherwise its just another reasonless rant.

Well if we’re going to discuss how production model aircraft will perform, how about we wait for a production variant, before making all sorts of fantastical BS claims. Even the Russians don’t claim a better RCS, so it’s tiring having to keep beating this horse. I’m sure it’s going to be a great plane, but it’s obvious that there were different priorities in the design.

come on, its amazing aerodynamics ! Thats what I’m talking about. On top of t, its stealthier than any super maneuverability fighter out there.

Stealthier than a Flanker yes, but not stealthier than an F-22.

RCS is not what flies better ! As much as RCS, there are always improved missile countermeasures.

RCS will determine the likelihood of having to use those aerodynamics/countermeasures.

The difference between the F-35, and previous aircraft is that the pricing includes an equipped aircraft(i.e. avionics, etc…) vs. various external pods, and such. So…to compare the price of a base legacy fighter w/o its go to war kit vs. an F-35, isn’t exactly apple to apples.
