Yup, canards literally means ducks or goose or something like that in french. So they are mostly good for eating especially if you fatten them up like what the french does.
Russia to get SU-35 by 2011
- Thread starter F-15 Eagle
- Start date
next u are going to tell us Thrust vectoring was used because the tail was heavy.

Wrong its the Su-27. I think it was called LL-UV or something like that and there was another designation as well. Initially they tested the flat nozzle before moving to a round one.
The Su-35BM (Bolshaya Modernizatsiya - Big Modernization), undertook alterations in its fuselage, weight, RCS, embarked avionics, radar and bombs. Originally the Su-35 project did not contemplate the adoption of canards, however during the development of the aircraft at the beginning of the 1990s, the radar was installed then in development N-011M “Bars” in a prototype of the T-10 / Su-27. At the beginning it was noticed that the extreme weight of N-011M Bars affected the center of gravity of the aircraft, the radar was much heavier than the N-001 radar of the original Su-27. This compelled the designers of the aircraft to adopt some system that supported the frontal surface of the aircraft. The solution of canards appeared to reequilibrate the center of gravity of the aircraft. It was noticed in the flight of tests of the Su-35 that canards had improved the stability of the aircraft, improved the sustentation capacity, in closed maneuvers with very great angles of attack. This change made as much “success” that was adopted in other variants of the Su-27. The down side was that it increased the aerodinamico drag in supersonic regimen and even more increased the wing area of the aircraft, which resulted in an increase of the RCS of the aircraft.
Aiming at to reduce the RCS of the aircraft, the designers of the T-10 had opted to remove canards from the aircraft. But to make this was possible it would be necessary to reduce the weight of the embarked radar, with the purpose of re-equilibrating the center of gravity of aircraft without the use of canards. This was possible with the new radar that was in development and that will have substantially inferior weight to the N-011M, having had similar weight to the original N-001 of the Su-27. This minituarization of components and use of in the manufacture of the parts of lighter materials, allowed the center of gravity of the aircraft came back to be as the original Su-27, making possible withdrawal of canards of the aircraft.
...and I'm not even gonna bother to give a link to the website of the quote coz some [Admin: Text deleted.] here think they are too smart to come and make such cheapshots at me without even doing some research.

All I know about the SU-35 is that 15 original ones were build but will never enter service. One SU-35BM is in test flights might be exported and Russia plans for 182 of them but with their crumbling defense industry and their tight defense budget I doubt they will get more than 20 of them plus a few for export. Their dreams of the PAK-FA will probably never enter service as well.
You don't have to agree with the people on this board but you will show a little respect to your fellow posters, no name calling, no unnecessary bickering and if you have a source post that source if possible. We are keeping an eye on this thread and if the maturity of the discussion does not improve the thread will be locked and the problem posters dealt with.
The original Su-35 has "entered service". According to scramble the Su-27M (Su-35) is in the 968 IISAP in the Moscow MD at the Lipetsk air base. One Su-35BM has been built for testing, with two more undergoing construction right now. Around 2-3 regiments are planned (which is 48-72 aircraft) for the VVS. The PAK-FA is scheduled for flight testing and public debut next year. Until then anything you know about it (including costs, effectiveness, likelyhood of entering service etc.) is nothing but rumors.
As a general rule, anyone trying to paint a picture in one color is wrong. Things are never as simple as that.

Do anyone know if this is the Su-35BM No. 901 or is it the next in line,
No. 902?

That's the first prototype 901. Others haven't flown so far.
OK initially I didnt wanna post this link, but after some communication with AegisFC, I've changed my mind. Others should not be denied the knowledge of it.
This is the history of why the canards appeared on the super Flanker series. Its a hard find coz not many websites talk about it.
http://www.globalsecurity.org/military/world/russia/su-35bm.htm
But with the new Su35BM, they removed it to reduce the RCS, which was facilitated by the emergence of the IRBIS-E radar.

Do you know of any other RCS reduction changes on it?

I think they reduced the RCS of the fan blades in front inlets, by using newer alloys on/in it.
Same goes under the wing mounts/weapons mount, you can actually see it on the Youtube clips..
They somehave smoothing(reducing the RCS) on the weapons mount's.
couldn't find the source, sorry..
I remember reading on another website that they manage to reduce the RCS of the plane to the size of an F16. But I cant find the source now, so I'll leave it at that. But the SU35 BM is banking heavily on RAM coating all over the air frame, inside the air inlet, fan blades, cockpit canopy etc.
I would like to know on the supercruise update on the engines though, coz a Flanker with a full supercruise performance as targetted by sukhoi, would be really really tough plane to beat in A2A combat.
And would make it awesome as hell in A2G given the Flanker's already incredible range. But Sukhoi never mentioned supercruise about the SU-35BM. This was just speculation on part of the press because they thought it would have 5th-Gen fighter engines. Instead it will just have re-worked AL-31F's with TVC.
It could be able to supercruise but if it can the Russians haven't announced yet.
And about the RCS of an F-16 thing, you got that from GlobalSecurity (which I personally don't use often).
They are banking on Supercruise engines for the SU35BM. Currently the works are ongoing to get the thrust up to their expected power, and make it reliable enough to have a very good TBO. But in any case, even if it doesnt achieve supercruise because of its external loadout and non optimised airframe for the supersonic regime, it will still boost its ability in A2A alot, as no other fighter other than the typhoon and F22 have supercruise engines.

I read "AL-41F1A TVC turbofan engines rated at 142-147kN" several places, but i am not sure if this really is the engine that will be installed on the
Su-35BM.
"It states categorically that the SU-35-1 design, unveiled at Russia’s MAKS 2007 air show, is a single-seat aircraft without canard foreplanes, but with a lighter airframe than the SU-27, enlarged fan and engine inlets, 2 NPO Saturn/Ufa MPO Item 117S engines that reportedly offer thrust vectoring and supercruise performance in clean layout, 2t more fuel, modernized electronics at all levels, a Tikhomirov NIIP Irbis (updated N-011M Bars) passive electronically scanned array radar, 6,000 hour airframe life, and 4,000 hour engine life."
http://www.defenseindustrydaily.com/Russias-SU-35-Mystery-Fighter-No-More-04969/
The engine is a modernized verion of the AL-31F and not completly new. They increased the diameter on the fan blade and integrated the FADEC= full-autoryity-digital-engine-controll system. It is a increase of 16% power from the older AL-31L engine.
They build 5 of these engine between 2003-2007.
They used 2 of these on a Su-27M testbed from Mars 5 2004.
Engine 117-04 and 117-05 is used in the Su-35 No901 today.
They will soon complete 8 more of those 117S's.
