I think the T-50 is actually smaller, but then we need any official data, but the nose, at least in close dimensions is more in the size of the Mig-29’s nose than on the Su-27’s nose.

People want it to be heavier,because they think heavier is better…as if the 22’s 5 extra tons is a bless and not a curse…that is the Raptorfanboishn..

So much trash from sferrin, djcross and Amiga…you guys don’t even know what you are looking at.

People think the exhausts of the F22 have something to do with ‘stealth’, but don’t realize that almost all the research over TVCs done in the west in the 80’s was done with the flat panel configuration, because the poor engineering on that field, at that time.

If people think that a few perimeter % does have an impact on a very high temperature stream, they have fallen on the ignorance campaign over all this stealth thingy, BTW, the flanker exhausts does have higher perimeter than the F22’s ones..and more important, bigger exhaust area (which for all this IR issue is the really important thing)

Even if there goes nor not the wheel, the structure is strange, and not consistent with any other similar system, like the su27 or mig-29, and this hole is going very inside the intake, or at least it seems.

I wont reply your meaningless walltext of no sense…Sens, read a book of physics.. size is important

I never said reducing the RCS was not important, read again my post

The “interesting structures” you see are the variable geometry intake.

No, the base structure on the intake is not a VG ramp

And the very deep landing gear structure is not a VG ramp either

The VG ramp is on the top of the intake

The problem is, the radar energy does not behave like air. It is not of intrest how much did enter the inlet, but how much of that will leave it to give a signal from that. As long there is a direct line of “sight” some problems are still alive.
It may not matter too much, when some higher peaks are created in other areas of the Su-50. The first impression does show,

The problem is that we don’t know enough about this intake, there are at least 2 pictures showing interesting structures on it, something is going on, but we don’t know yet what is exactly.

the Su-50 is a semi-stealth design for cost and flying performance reasons

For many, every aircraft after the F117 is a ‘semi-stealth’ plane, because flying performance issues..mainly

Stealth was always for fighter programs something like a hat or a glove, while the core and body of the program was aerodynamics and physical performance.

I would like actually if the T50 is meant to do other kind of maneuver, you guys are concerned about the ‘nose authority’, ‘turn rates’ ‘roll rates’, all conventional values optimized in the 4th gen planes.

But there is a lot, a lot more to optimize, planes are still limited in some basic maneuvers, planes are still limited to some altitude g-envelopments, there is a lot to do in the aerodynamic department…if you are limited talking about turn rates, roll rates, post stalling , nose authority…you don’t have any idea what is (or should be, for the nowadays capabilities, and the research done) super-maneuverability.

Time will tell, if the T50 is meant to be a truly super maneuverable 5th gen aircraft, or just a cool plane with lower stall speed /lower g-handling speed

The F22 is not a 5th gen super maneuverable aircraft, is just a cool plane with old fashion TVCs

Will the T50 be just a cool plane with a 3D tvc?

You guys are talking about completely ambiguous things

What if this mobile lerx actually relief workload on other surfaces?

Is stealthy? is not stealthy?….who cares, even the pogo-san dint fall in the tale that the F22 is a uber stealthy aircraft by shape (but it helps anyways), and actually the technology moved from this to RAM, using conventional airframes (like the 22), why? because is not practical, you can get your nice RCS value in a test room, but an aircraft is always moving, always changing it relative aspect….oh God i did a wrong banking! OMG my RCS!!! do you really think pilots are flying in that way?…kids.

‘Stealth’ is only worthy with proper ECM coverage.

Trashy thread that has turned thanks to tadepani /dynamo and co.

Anyways, to the topic

There is an interesting feature on this T50 thing, the nose is pretty bolted/riveted, now this is interesting, since in general, nosecones are made of a single piece of composite material (glass fibre), now this could mean a couple of things

1-The russians will beat some records with this T50
2-There is actually a structure inside the nose (no idea what could be)
3-The russians are trolling me 🙂

Now, if they want to beat a record with this plane, then why all the other things around, like the IRST ball, and the probable MAWS ball?…

[/ATTACH]

Interesting

The 5th generation will be known in the future as the ‘lost generation’

Well, i must quote my own remark on here…because i’m being fatalists, and probably over pessimist

The pakfa, for some is a f23, for others a su-27

But looking it again and again, it seems to be , conceptually, a new airplane, based on the 80’s aerodynamic research (the golden age for aerodynamic research IMHO), probably some will say the F22 and the F35 are based on this research, well, they are not, really, the early ‘black widow’ was, before it ‘stealthification’, it was a beauty aircraft, not that sad abomination that ended in the yf-23, but anyways it was based on the 80’s research.

The T-50 is a mix of the F-16Xl and the F-16 AFTI concepts , it seems the aircraft is based on a similar russian research, and of course the multiple control concepts from the su47 and 144.

Well, this can’t be that bad

Now people are worried about the planform alignment, the ‘high rcs’ tunnel between the engines (ever seen the f-23 from above?)

kids, the high rcs ball!, the high rcs tunnel, the high rcs intakes!

If we have any kind of real knowledge about waves (just mechanical waves, not even radar, which is even more complex) we would be stuck in a endless debate

Are the f22’s intakes that ‘stealthy’, while is hiding the engine?, it is showing a rounded proportion because it high angle exposed due the side missile bays placement..is that really stealthy?

what about blockers with better angle incidence?, or the air feeding duct covered with ram to allow continuous absorption?

Why the F-117 did prefer radar blockers over the s-duct?

*******

Anyways, let’s see what will happen with this pakfa thing, will be able to perform change of direction without banking? will be able to perform any kind of exotic maneouvre, no, no more º/sec, but maneuvers that can’t be done with conventional controls (even TVCs), will be able to explore the high altitude g envelopment?, is meant to achieve all these goals?

Who knows, probably the pakfa is actually a 5th gen aircraft, and not just a conventional layout with some cool edges
