Sukhoi Su-27/30/33/35/37 Flanker series & Su-34 Fullback - History, Design, Performance & Dissection (Part 2)

That doesn’t make sense.

Can’t get better than perfect.

Perfect things aren’t being completely redesigned in a middle of development. One can only speculate what Sukhoi would’ve cooked if all that time wasn’t wasted and ЦАГИ taking as big involvement with development as it had with MiG when they worked on a MiG-29

imagine how surprised the engineers at GRUMMAN were when they saw the first photos of the Su27, realizing that they wouldn’t have to spend INSANE amounts of money on new larger radars for the F16 and F18 because the Su27 has up to 1000m RCS with even the R27, not the R77

Sounds like bs
While it is large I don’t think its that large

I remember a picture of an Indian Sukhoi parked next to a Rafale, that was quite the whiplash. As well as seeing them get towed by full on trucks and the trucks still looking small.

That’s an exageration, he knows it’s not that big. a RCS isn’t even in meters but in squared meters, he’s not giving a real figure

Yeah it’s more around 15-20m^2 not 1000.
Imo he’s being hyperbolic

Holy sheet of paper that’s actually huge xD
And I thought the F-15’s rcs was big

this is real figure

nope 15-20m is minimal frontal rcs

First off, please give numbers in m² and not m, it’s incorrect and triggers me.
Then, can you provide a source for that? 1000m² is, like, really big… That’s 10% of a hectare, do you see how much that is?

you are misunderstanding the RCS term, which has nothing to do with geometric area

Ah nevermind, I confused with RES. But then 1000m is way worse, where in the world do you pull that from

what is res?
i mean radar cross section

1000m2

Radar Equivalent Surface, not sure that’s how you say it in english.

I’m starting to be really confused, I’m just gonna research further because I now realize I don’t really know how RCS is calculated

Ok so from what I checked, this does in fact have to do with surfaces, as the RCS is a way of associating the radar return of an object to that of a perfectly reflecting sphere, where the RCS value is equivalent to the cross section surface of that sphere. If that definition is correct, then we are in fact talking about a sphere of width 30m which is absolutely enormous.

yes, because sphere is best low rcs form
btw i checked my old sources and i will reup numbers
mid rcs of su27 with some missiles is 300-400m2, but peaks up to 32000m2

I’m not certain, but it seems like quite the opposite to me, a sphere reflects a significant part of the radiation back to where it comes from. That’s also what many websites seem to claim

That’s absolutely gigantic, but fully loaded I can maybe see that with some resonance now that I think about it… Could you show your sources? I’m curious
