Baseline Su-27 is significantly lighter then Su-35 . Planes tend to get heavier with improved avionics and engines. I doubt that J-11B weighs less then J-11A . What really matters is T/W and TVC .
The J11A achieved a fair amount of weight savings over the baseline Su27SK. The J11B is likely heavier than the J11A, but still likely significantly lighter than the Su35.
You need thurst and weight to calculate T/W ratio, you cannot do that when you don't know the weight! Without knowing the T/W of the two, you cannot reasonably conclude which has the better aerodynamic performance.
TVC is also overblown.
In a fight, its energy that matters the most. TVC can give you great nose pointing ability, but that comes at the cost of massive looses in energy (airspeed and altitude), making you far more vulnerable yourself.
Limitations of delta-wing are well known . Add to that significantly worse T/W ... you get my picture.
Except the J10 is a delta-
canard, not a mere delta.
Everyone bar the Americans, including the Russians themselves, turned to delta-canards as the next evolutionary general aerodynamic configuration for their fighters post 3rd gen (which includes the baseline Flanker, on which the Su35 is based).
Prototype, delta-wing, stealth shaping and again worse T/W .
Again, delta-
canard. Also, stealth shaping does not necessarily mean poor agility. It makes it harder to meet both design criteria, but is far from impossible.
Yeah right
Pilots tend to push their planes to the limit in demos. It doesn't need to be at low altitude or in air show . Fact is, nothing compares with Su-35 regarding maneuverability today. Not even F-22 or PAK FA .
Believe what you want, but I tend not to call well respected pilots liars unless I have damn good evidence to support it.
Anyways, the Su27/35 was designed for medium to low speed manoeuvrability, in keeping with the general air combat theories and tactics of the time.
Since then, air combat theory and consensus has evolved to place far greater emphasis on trans-sonic performance, in which the delta-canard has distinct and significant advantages over legacy 3rd gen designs.
Air shows are typically held at medium to low speed, which plays to the Flanker's advantage.
In real combat, the delta-canards would be looking to play to their own strengths.
That is why I find serious conceptual faults with you trying to determine aerodynamic performance purely on a very few cherry picked parameters, to which you do not even have full and accurate data to make comparisons with!
And most of Russian combat pilots are highly dubious of value of stealth in real air combat
Is that why they are spending so much time and money developing their own stealth fighter?
Fact is, both stealth and super maneuverability have they uses . Stealth is useful to enable you to fire first , super maneuverability to avoid incoming missiles.
If you are dodging missiles, even if you do survive the first shot, you are already in a really compromised situation.
Well ... you have recent Su-30MKI vs Typhoon exercise, also Su-30 vs F-22 in Malaysia . In close combat more maneuverable fighter wins . BVR is a different matter .
Different people say very different things about those exercises. The British are saying the ROEs favoured the Indians and that they were taking it easy on them.
There are certainly plenty of other exercises where both the Typhoon and Raptors claimed to have seriously kicked Flanker tails.
At best I would call all of those exercises inconclusive unless we know all the pertinent information about them regarding important determining factors like ROE, scenarios used and the aims of the exercises etc.
I'm certain they do, that's why decided to purchase Su-35 .
Is that why they are only buying a token amount and only after years and years of Russia aggressively pushing the type, with the PLAAF never having shown any real enthusiasm towards the deal?
This deal is as good an example of a politically driven buy as one you are likely to see.
The very long negotiation time is a good indication of the degree of resistance to it within the PLAAF.
