its because

1. The first pictures of the T-50 showed a bottow with odvious open vents and bumps that do not say stealthy in any way shape or form. Im assuming that there is more than 1 prototype with 1 T-50 with a cleaner bottom.

2. The T-50 is using a legacy engine ATM which we seriously DOUBT has been treated for any LO. We know from press releases that the new F-35 builds have treated tail feathers.

3. The canopy it self doesnt lend itself to stealth it doesnt look stealthy
its not a gold transparency like the Raptors its not a single peice like the F-35

You seriously don’t have a clue – and you wonder why informed people get irritated over you posting nonsense like this? It’s meaningless!

1) Look at the build quality of the 2nd Su-35S and the latest Su-34s – that’s “production variant” quality construction!

2) That legacy engine already produced 15.5T of thrust and one of the bureaus is designining a MORE efficient ‘flat’ TVC nozzle for it than that of the F-22. That was old news.

3) The RuAF requirement is a frame-less canopy. It is in the work and you will see it on production models.

Where is the report button mods? we have an out of controll troll here!

I don’t think you have any idea what a “troll” is – do you?

Questioning the underlying, fundamental validity of the posts here is not trolling, so good luck brushing it off as such. :rolleyes: Till now, all people have done is cry – rather than provide any basis for their (baseless) arguments regarding things like RCS, avionics integration, and whatever else there was…

speculations based on existing data can be educated guesses. Thats what makes forums fun in general.

It is very annoying to have a ball of negativity trying to shut this thread. You are disruptive, and aren’t very smart if you keep coming back to thread you find worthless. Why don’t you just stop responding. Aren’t you wasting your time here? ..not to mention annoying as hell.

Cry me a river, ignore me if you like. I know you dislike being told that 99.99% of the speculations are – just as I said – worthless.

From what is clear and undeniable, there’s no one in their right mind who would suggest the F-35 is a better overall aircraft than the T-50.

So: you don’t know it, and you can’t even imagine that someone else knows! That’s why you’re so angry!
There was an article written by Pogosyan (Sukhoi director) about stealth fighters. In this article there was a graph showing the RCS of the Flanker. Also, he wrote there that Eagle’s RCS is 10 m2 (few days ago I posted here, on KP, that it’s 15m2, but today I checked the article and it says 10 m2 – my mistake).

I’m just rather irritated that some forum schmucks, who are now very upset, even bother trying to figure out the “real” RCS of anything stealthy when no one will tell them any real or, more importantly, COMPARABLE figure.

15m2 for a Flanker sounds reasonable at a “medium reflectivity” angle with full on-board stores.

Either way, even 15m2 of directly reflecting surface is a LOT of reflection. I would imagine the Flanker would have to reflect with its underside to get that kind of reflection of radar signals.

Ok, Su-27UB probably has bigger RCS than Su-27, but why would there be a significant difference between RCS of Su-27, Su-27SM or Su-30MKI? It’s the same airframe(ok Su-30MKI has canards). Su-35BM is a different story and probably has lower RCS.

Su-27UB and Su-30MKI have more in common due to dual-seating with one another than the Su-27UB and Su-27SM. So not sure what your point there is?!

The Su-35S has been reshaped and uses RAM, and has been quoted to be around 3m2 as far as I can recall.

USAF measured the Flankers they bought from Belarus in 1994. We can guess that those measurements established a baseline for RCS estimates of Flanker upgrades.

So the Indian MoD quoted the US figures?

Who is to say they are accurate – upon what has been released that is.

DIONIS,

why so hostile ? Its not nice to try to shut this thread every step of the way just cause you don’t like it.

This thread is a joke. The facts are clear. The speculation is worthless.

I’ll tell you what’s obvious – you have no clue about Flanker’s RCS but you mock me. Funny.:rolleyes:

But you pretend to know it? Give me a break.

i guess the indians dont know the rcs of their own planes

http://www.business-standard.com/india/news/india-russia-close-to-pactnext-generation-fighter/381718/
Sukhoi’s FGFA prototype, which is expected to make its first flight within weeks, is a true stealth aircraft, almost invisible to enemy radar. According to a defence ministry official, “It is an amazing looking aircraft. It has a Radar Cross Section (RCS) of just 0.5 square metre as compared to the Su-30MKI’s RCS of about 20 square metres.”
That means that while a Su-30MKI would be as visible to enemy radar as a metal object 5 metres X 4 metres in dimension, the FGFA’s radar signature would be just 1/40th of that.

What angle?

Who measured it?

If it isn’t obvious… there’s no point.

As I said – ‘overall’ RCS figure makes no sense. For example – average Flanker’s RCS from the side is closer to 40 m2, nose on – 20 m2. The most important is frontal sector RCs, so I think they’re refering to frontal RCS which we know that is ~20m2.

Rofl…

Cant you read? I said the thread was speculation! I dint claim to post the most accurate stats but ASKED for an informed opinion. ****** Look I think this board would be a better place if we did NOT have people barging in insulting people. your attitude is not necessary. I have edited my post so as not to flame.

What informed opinions are you looking for? Some LM or Sukhoi engineer that wants to be put away for treason? Or some eyeball-RCS radar testing from keypub expert? SERIOUSLY.

Want some more likely to be true facts? Here.

T-50:

-More weapons onboard than F-35.
-Ability to use larger weapons.
-Better radar coverage (multiple radars) and larger radar = highly likely better A2A engagement capabilities.
-Likely far faster both max and mil thrust. At least some advantage here is a given to the T-50.
-Longer range.
-Thrust vectoring allows for enhanced maneuverability.

F-35:

-Carries SDB which allows for good “small time” ops like counter-terror

–But SDB isn’t exactly something that can’t be created by someone else.

That’s about as educated as any “opinion” gets here.

There has been a lot of talk lately about how superior the T-50 will be over the F-35 and even over the Raptor. How do you feel the fighters will match up?
It seems that since both the T-50 and F-35 are primary exports, that they have a much greater chance to meet. Please keep in mind this thread is mostly speculation and for entertainment purposes. we know very few techinal facts about either aircraft. But bases on first glances and educated guesses what to you feel will happen? Will the F-35 have the sensors to get around a energy disadvantage?
The F-35s PROs:

* Advanced intergrated sensors*
* Very stealthy design*
* Much greater situational awareness, 360 degree irst*
* A fuel load greater than 4th generation types with external tanks*
* HOBs missile capable + DIRM in future upgrades*
* will be bought in great numbers maybe 2 to 1 odds*
Cons :
*Very little if any super cruise*
*NO TV nozzles*
* limited A2a Missile load*

T-50 pros so far
* It looks like it has good kinematic performance*
*super cruise*
* Lots of Lots of Aesa radars including a rear facing one*
* TV nozzles*

Cons:
* Not as stealthy from many aspects*
* older engine design*
* no dircm*

Your pros and cons are in general nothing but personal opinion and speculation. This thread is worthless.

Sergei Bogdan is a big fish – he tests everything. The PAK-FA – him first. The Su-35 – him first too.

That’s a pretty poor landing by that Flanker pilot.

No, that’s a demo of the AI on the machine. Something that the PAK-FA will have too, and that has been introduced on the Su-35S.

The system corrected the landing very quickly and successfully.

It will be unique to those fighters and will prevent incidents like those of the Su-37 – so should come in handy in ridiculous dogfight maneuvers.

Gap or no gap – if China wanted to, they could obliterate or take over Taiwan. And the US wouldn’t dare pull anything unless hordes of its civilians or servicemen were being killed.

NSM and JSM are going to need a hell of a lot of launches to punch through a TOR and S-300F level defense.

Something to consider 😉

Given your scenario, I assume that’s not the case. If China were to stick to Russian top notch tech for the “time” – Norway would in NO way outclass them OVERALL.

If China is on its own, I’d say it’s a toss-up. Hard to say.
