they are old Su-27s, and probably a bit of propaganda, but Su-35 is the real yard stick pitting a Su-35BM against a J-10S will be interesting to see who is better, new upgraded flankers of the Russian air force with have Su-35 will have TVC nozzles and Supercruise and probably the Su-30 will add supercriuse with the new engine.
AL-31F M2 engine contemplated by OKB Sukhogo (Sukhoi Design Bureau)
28 February 2012, Moscow – Technical experts gathered at FSUE “Gas-Turbine Engineering RPC “Salut” for a conference to review the results of Salut's R&D efforts towards implementing the 2nd Phase of the AL-31F engine modernization (known as AL-31F M2). OKB Sukhogo is showing interest in the engine upgrade to pursue the repowering program of Su-27SM and Su-34 aircraft of the Russian Air Force.
The R&D appraisal meeting – the first one after a five years' pause – saw the participation of all the parties concerned: “OKB “Sukhogo”, “Lyulka NTTs”, “United Aircraft Corporation” and “United Engine-Building Corporation”. The project status report was presented by Sergey Rodyuk, who noted that all the activities for the second phase of the engine upgrade had been in close adherence to the specified timeframes. The special program of the 2nd phase engine bench tests in the climatic test facility at TsIAM has by now been completed with the results demonstrating the engine's capability of attaining 14 500 kgf of static thrust and proving its design performance parameters in flight conditions. Compared with the first-phase AL-31FM, the latest iteration has a 9% higher thrust during flight operation.
“The overall engine size will be subject to no trade-offs so as to keep the AL-31F upgrade conveniently suited for re-engining of the whole inventory of Su-27 aircraft without any additional airframe and engine nacelle modifications.” - said Gennady Skirdov, Salut's acting General Designer.
It is planned to have the program of special test-bench and endurance tests accomplished before the end of 2012 and go ahead with the special flight tests, which precede the state certification tests.
Vladislav Masalov, Director General of Salut, said that the full-scale deliveries of upgraded engines could be started as early as 2013. “The AL-31F M2 engine can be a not so expensive solution for re-engining of Su-27, Su-30 and Su-34 fleet now operated by the Russian military and is likewise deliverable to foreign customers,” noted Director General. The technical specifications and requirements of Su-27SM and Su-34 aircraft call for the engines with increased thrust and improved fuel consumption with the AL-31F M2 fulfilling these requisites. The installation can be performed without any rework of the aircraft and take place in field conditions.

Russian Aviaton » Friday April 13, 2012 18:54 MSKThe specialists of Obninsk-based Technologiya research and development enterprise have developed the metal-optic nano-coating for the canopy of combat aircraft, which protects the pilots against radiation and intense solar radiance during altitude flights. It has been declared by the Director of Steklo research and development division of Technologiya, Valery Temnikh, Lenta.ru reports.
According to him, the new coating should be applied on the inner side of the canopy and it decreases the warmth of solar flux by 40% and the radiation – by 30%. In addition, the coating decreases the electromagnetic emission 250 times and increases abrasive wear resistance and wear resistance. "Various metals are applied to the canopy and the light transmittance should be at least 70% after this procedure", - Temnykh said.
Follow us on: Besides, the new coating will help decrease the cockpit’s radar signature by 30%. According to Temnykh, the radio signal is reflected by the finished glass and the quenched signal spreads in different directions. The overall coating’s thickness is about 80 nanometers. Technologiya uses special magnetron deposition equipment for applying the coating to the canopy. The coating will be applied to the canopy of Т-50 (PAK FA), МiG-29К, Su-30 fighters and Su-34 bomber.
The mass-media have reported in late March 2012 that Technologiya have used gold sputtering in order to protect the pilot of T-50 against radio waves and solar radiance. According to the Chief Designer of Technologiya, Vladimir Vikulin, indium and tin are also used besides gold. The thickness of one layer is 20 nm, and the overall coating’s thickness is around 90 nm
