Which matters how? Nothing about the nacelle nor internal geometry of said nacelle is similar to the Su-27, nor even the engines.
Worse? It has 2 layers of it that are specifically designed to trap any stray radar waves, not simply reflect them. From what has been seen it’s far better than the F-117’s grates.
What exposed engines?
It was supposed to be an air superiority fighter… It is, and also includes many air to ground capabilities due to circumstances that are quite clear and obvious.
The supercruise performance is classified, as is the F-22’s. Initially it was thought the F-22 was limited to 1.4 mach.
Additionally, work on the true production model engine for the Su-57 is almost complete.
So, I’m not arguing here, just stating, I spoke with a F22 pilot and crew chief and we were at Langley afb, they code the screws (idk with what) so they aren’t visible on radar, that’s what I remember hearing, don’t attack me for remembering, but it doesn’t really matter if the screws are exposed if they are designed/manufactured to be stealth?
Ummm, both images are?
It is an Su57 but ig there was a new modification i had missed out on, even so the Su57 is not nearly as abundant as the F22, and the Su75 which is suppsed to be their actual 5.th gen fighter. Althoough this point is a little off topic.
They aren’t visible to begin with, it doesn’t matter what coating is put on it.
They aren’t? One of them is a T-50 from 6 years ago, the other is Su-57 81774 (2nd production model) from 3 years ago.
Ok and?
That quite literally in my head is the same if not a tad bit different.
It isn’t an Su-57, unless you mean to tell me that the “new modification” was the base production model of the aircraft.
Which is relevant how…? Legitimately… Who asked?
Yeah, you don’t say. I’m surprised you honestly thought to say it.
The image presented wasn’t of an Su-57, so the point of “exposed engines” is moot .
Your head might need a bit more knowledge then…
Its not ruper relevant to the particular discussion at hand, but in the relation to stealth aricraft and nation arsenal its pretty significant, and although Su57 isnt built for the purpose of full on stealth aircraft, the F22 can keep an airspace completely clean, and can be fitted with ground capability as well. making it quite ambigous though granted maybe not fully to the extent of the Su57, theyre really just two counterparts good at each their own thing. The F22 being more build on stealth as a principle and the Su57 as an affordable slightly stealthy jet
Obviously not, since you’re very clearly having issues voicing your argument… I have no clue what you’re even here for.
Cool, stopped reading past this.
Okay
only to a limited degree F-35 is what actually provides the CAS capability
It matters in a way, maybe not the way most people expect. Technically a radar wave can’t really reflect on objects smaller than their wave length size, since stealth is mostly concerned with X-band (about 2.5 to 4 cm) and around that, small mm-sized screws can’t really generate proper reflections back to the radar source.
HoWeVeRrRrR, instead of reflections, other phenomena can happen when electromagnetic waves hit objects smaller than their wave length, as well as the plane, such as scattering, and ideally you want to mitigate that as well because a scattered wave is still energy that might go back to the enemy’s radar.
When an EM wave hits the aircraft, it doesn’t all bounce immediately back, some of the energy travels along the surface of the airplane until it reaches a sudden discontinuity in the airframe geometry – discontinuities such as sharp edges, or such as the “bas relief” holes in which the screws go.
If you heard about the “continuous curvature” technique for stealth, that would be it: try to have nothing disrupting your aircraft fuselage. The less panels, less edges, less gaps, the better.
Secondly, EM waves also tend to scatter when they reach sudden discontinuities in material conductivity – such as from a metallic screw to a composite panel from the fuselage.
Those would be two reasons I know of to try flushing the screws as good as possible.
Of course, engineers know of those and actually use those properties to control EM wave direction, it isn’t anything new or groundbreaking in stealth tech.
Edit: I also updated my other post in this thread with some more lectures on the F22, some info regarding performance there that might interest you ppl.
True, just tried to keep it between the F22 and Su57 because that was originally the topic at hand :P
I wish y’all would just agree to disagree, cause there is nowhere near enough info on radar specs or stealth coatings to know either way.
No people must believe the narrative that either one side is decades ahead and that parity in any sense is impossible
