Moram izdvojiti ovaj deo
Citat:"The current progress of the Su-35 testing program confirms the earlier announced timeframe for the deliveries of the aircraft to Russian and foreign customers in 2011," the company said in a statement.

aerodrom ::Da li neko zna zasto noviji primerci Su-35BM i Su-30 imaju crni okvir oko kokpita?
Pretpostavljam da je u pitanju "stealth" premaz i zastita?
U vezi 'stealth' premaza, naisao sam na sledece
Citat:Russian Stealth You Can Touch
Checking out the Zhuk-M1E radar at Aero-India - the new unit developed by Phazotron for the MiG-29M, MiG-29K and upgrades - one detail was obvious: the backside of the radome and the front of the bulkhead were covered with what looked like something you'd clean the barbecue with.
It's radar-absorbent material (RAM) and pretty effective RAM at that. Nothing very exotic, but it does not need to be, since it is sealed up inside the radome and protected from aerodynamic forces, heat and moisture. In fact, US RAM specialists Emerson & Cuming sell a very similar product on the open market, an open-cell plastic foam doped with carbon absorber.
Russians are not stupid and do not do things if there is no point, and there would not be a lot of point in dealing with the radar-cross section (RCS) hotspot from the radar antenna if they had not also dealt with the other sore-thumb hotspots, namely the inlets/compressor faces and the cockpit.
The technology to do this was described in detail in technical papers delivered in London some years ago by representatives from the ITAE research institute, who had applied it to the Su-27 family. ITAE had even worked out how to apply RAM directly to the first-stage fan blades, which is quite a neat trick, and had devised spray-on RAM for missiles.
One may assume these or similar measures are available to MiG.
The same kind of measures are also used on many Western aircraft, but are usually not shown in detail unless someone screws up:
Whoops. That's a Have Glass II F-16 and the white plastic shroud around the radar workings is RAM.
Reducing the front-sector RCS, mostly in X-band, is a far cry from full-up stealth technology. It does not make the aircraft invisible. But what it does do (and quite effectively) is make jamming more effective by reducing the burn-through range (the point at which a radar defeats jamming because the reflection is stronger than the jamming signal).
The lesson: Any combat-effectiveness comparisons that are based on the old standard for the nose-on RCS of a fighter - around 5 m2 - can be considered invalid.

Ovo gore je za Mig-29 ali isto verovatno vazi i za SU-35....jos nesto zanimljivo vezano za Mig-29K. Obratite paznju na zig-zag sar koje su navodno deo mera o smanjenju radarskog odraza

Zanimljivo je to sto u tekstu kazu da planiraju da ga proizvode do 2020,ako sam dobro shvatio i da planiraju da izvezu oko 160 komada  (moze nama jedno 16,taman nam toliko treba...)

Ispitivanje Su-35 tece prema planu.
Na sajtu Suhoja moze se videti nova serija fotografija aviona 902.

meni je cudno sto rusi ne odustaju od koncepta pilotske palice u sredini kokpita.
