Guys honestly, new year’s eve and we are spending it on forum?
what about canards?
Sm is a bit heavier

Yeah i forgot about the cockpit, It might feel like the current su-33, it would be worse if it didn’t have improved engines
well, I’m really looking forward to the su30sm.
actually I have another question, will there be any sukhoi that will have full rwr coverage? the su27sm has blind spots 90 degrees up and down, will we still face this -problem- in the future with like su35s?
At normal takeoff weight, the Su-30 will be better…
Su-35s Should have same TWR that a Typhoon. With “Normal takeoff” maybe a bit worse but its about how much fuel the Su-35s carry in the “Normal takeoff” (it can carry A LOT). Also pretty sure Butowsky info about Empty weight of the Su-35s its just wrong. There is no way that the Su-35s weight more than a Su-33. Not when Su-30 is around 17tons.
If we got with this page. StatShark - FM Calculator. Su-30sm should be 1ton heavy than the Su-27sm in game.
Seems pretty light when you consider the additonal weight:
Larger Canopy
Canards
Additional Canard control systems and redundancies
Additional crew
Flight journal claims 40,565 lbs or 18,400 kg
Avio news claims 17,200 kg
Sukhoi’s website has a PDF and they directly state the following;
Maximum fuel capacity for internal tanks is 11,500 kg. The normal takeoff weight with 2x R-77 (175kg x2) and 2x R-73 (105kg x 2) is 25,300kg.
25,300 - (175 x 2) - (105 x 2) = 24,740 kg.
Assuming “normal” takeoff weight is 50% fuel, that would imply 1/2 of 11,500 kg can be subtracted from the mass. This leaves 18,990 kg empty mass but that seems too high.
Assuming a fraction of 60% internal fuel we can take 0.6 * 11,500 for a empty mass of 17,840kg which is far more likely.
If the empty mass is 17,840kg the empty T/W in static conditions is approximately 1.62 based on a total static thrust of 14,500 kgf per engine (as stated above by Sukhoi).
With the normal takeoff weight (no armament) and what appears to be a 60% fuel fraction the thrust to weight is 1.17.
With normal takeoff weight and 10x R-77, 2x R-73 the mass climbs to 26,700 kg and the T/W is reduced to 1.09.
The three measurements for the Typhoon leave it around ~1.67 empty, ~1.36 on 50% fuel, and with a full load of missiles (6x AIM-120 and 2x AIM-9) on 50% weight the EFT has a T/W of ~1.26

Doesn’t’ gaijin Add the Emergency thrust on the Russian engine? Or that was a one time thing for mig21?
They removed it from the MiG-21 if I recall correctly and they are not using emergency only modes for F-15. They are using “WAR” settings such as the 102% throttle for F-15 but not the VMAX emergency setting if that makes sense.
The Su-30SM is 19,710kg (not empty) according to primary documentation.

I was playing the bison. And that thing is still really fast… So i was under the impression that they still use it.
That make more sense.
I was wrong, 19,710kg is loaded not empty. I had to double check.

102% was the standard engine thrust,due to major problems with the F-100 engines the thrust was reduced. After the problems were fixed, all F-15s used 102% thrust.
102% engine trim is 100% of the F-100 PW 100 engine thrust. Vmax was not used.
That’s what I said, they are not using emergency only modes for the F-15.

Maybe the Su-35s Weight more because of RAM? I read somewhere that Every layer of RAM paint its around 250 kilos.
Also anyone has Info about 177s engines?
27EA most definitely exists, and K-77M isn’t an Su-57-specific weapon.
The T-90 was named such as it was a part of the 1990-1992 mass modernization of vehicles, and its upgrade warranted a new name. It shares little to nothing with the 1989 T-72, instead being founded on the 1990 T-72.
