1:11 @ vid ...this plane is razor thin !
Does it stand out from other 5th gen fighter in this regard?
J20 seems fatter so does f 22....not in any way saying these planes are less stealthy.
 
1:15 Did the T-50 just fire a missile? :mps:

:woot:

That wasn't real but a computer sequence.

That's the advantage of the design, by placing the weapon bay between the engines and not below them. That's why the T50, just like the YF23 have a flatter design, which will contribute to the RCS as well.
 
I don't understand why Indians need to put a BrahMos on every damn thing that comes into their possesion. Don't get me wrong BrahMos is an excellent cruise missile, possibly the best of its kind, but THERE IS NO NEED to install it on a slim 5th Generation jet fighter. It taints its excellent manuverability, at the very most you'll be able to fit one BrahMos, it's so pointless. Sacrifice those other few hardpoints for that one BrahMos? Its foolish. I can understand it being installed on the Su-30MKI as it's not as stealthy. The Pak Fa is tailor-made, specially made, with components and composite material, there's no need to wear out those materials by fitting a BrahMos.

First of all, it's not only India that has a requirement for long range cruise missiles on stealth fighters, any country has it. The US will integrate JASSM externally to F35, UK Storm Shadow and Russia wants to integrate long range missiles on Pak Fa as well.
Secondly, Brahmos 1 will not be used on FGFA, but Brahmos 2 which is smaller and lighter. The goal is to fit 3 x on MKI, 2 x on FGFA and between 1 to 3 on Mig 29K / Rafale.
 
The protective coating against radiation for the combat aircraft canopy has been developed in Russia - News - Russian Aviation - RUAVIATION.COM

The 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.

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.
 
lets hope so , & i hope they also built nirbhay cruise missile keeping PAK FA in mind :D



yes , the point is even if god forbids, pakfa is not stealthy as j20 we dont need to be disheartened as we would always have
edge on chinese on avionics , ECM & bvraam missile technolgy thanks to our reach in western FRANCE , isreali & russian
equipments .So we dont have to worry if pakfa doent turn out to be as stealthy as expected .
if they are able to make j20 stealthier than pakfa then don't you think that they will be able to even produce avionics,ecm,bvraam comparable to western world .i mean if they can master stealth in such short time then these things should not be an issue for them.

For J-20 what we see is a stealth airframe, and not mastering stealth. Russia "could" have developed such an airframe but they have a different idea. As per Chinese, I dont challenge their tech but "mastery" is something, that is yet to come.
 
EACH NEW GENERATION OF AIRCRAFT ENGINES REQUIRES AN INCREASE IN EXPENDITURE ON R & D

Moscow. April 14. Airports - Every new generation of engines requires an increasing amount of labor and financial resources for science, for scientific research (NCI), said Supervisor of CIAM Vladimir Skibin.

According to him, a few years ago an analysis of the dynamics of expenditure on science when creating new engines, which showed that the engine of the fourth generation of the total project funding was spent on R & D of 15-20%. When you create a fifth-generation engine of the total funding for the development of the project on R & D accounts for 60%. And according to forecasts, the development of sixth-generation engine for science and technological advance (NTRP) will take more than 70% of the total project costs.

Currently, CIAM was working hard to develop the methodology and the engine is expected in the coming years it will become available to all developers of engines. "Its essence lies in the fact that the developer has the right motor to begin research and development work, there is no necessary body of knowledge and advanced scientific and technological potential," - said scientific director of CIAM.

He noted that one of the most important tasks is the creation of CIAM NTRP. At the same time to create NTRP today imposed new requirements: the work must end technology demonstrator site or the engine as a whole. "One SRI is unable to create the necessary NTZ, must work with industry, EDB, enterprises," - said V.Skibin. Therefore, the decision to work together on advanced engines PD-14 and the "product 30" for the fifth-generation fighter has been fully justified. "To date, this joint work is being done with the Permian of" Aircraft Engine "and" NPO "Saturn" - he said.

Speaking on the importance of NPOV, V.Skibin stressed that today's aircraft engine is a revolutionary progress has analogues in other industries or on elements of design, nor the stress strain behavior at a temperature of not. In the U.S. and Europe accepted indicators of future aircraft engines. The problem in the near and medium term to create engines that have fuel consumption by 70% less, which puts tremendous complexity of the task facing scientists and researchers. Also provides for reduction of emission rates by 60-70%, a significant reduction in engine noise. "The long-term scientific studies it is important to keep up with Russia, it is necessary to make up the backlog, where it is still there," - says V.Skibin.

He stressed that in recent years have learned to consider CIAM, and thus produce scapular machine. At the time, our scientists and specialists, to some extent, jealous of the fan blades shirokohordnym hollow, domestic engine-blades are not made. Now in Russia, and are able to consider such blades, and produce them. The highest skill - to consider the kinetics of combustion in the combustion chamber in the light of turbulence. "This is a huge task, and it CIAM successfully solve," - said V.Skibin.

Responding to a question about the engine of the second stage of development for the future fighter PAK FA program, scientific director of CIAM said that the decision to start R & D over the engine of the second stage was taken over a year ago. Domestic engine manufacturers have shown convincingly that the Russian industry and domestic science in a position to tackle this very complex subject. There was some research done on the basic and defining the parameters and characteristics, the possibility of creating an engine with a very high performance turbine, combustion chamber, a fan. These works were carried out industry trials were conducted in CIAM, some tests were conducted at JSC "NPO" Saturn "and the NPC of gas turbine" Salute. "Was shown the possibility of creating an engine with the given parameters are not inferior to foreign aircraft engine performance. Today, this work has been going on in the OCD. The program, established co-operatives, has been appointed chief designer and the work is quite active.

Responding to a question on why were not completed work on the propeller-fan motor with a high bypass ratio of NK-93, V.Skibin said that the engine NK-93 was created in Soviet times for heavy military transport aircraft Il-106. Were created by experienced engine, conducted bench tests, the engine has been admitted to the flight test. CIAM was actively involved in all stages of the engine. However, from the very beginning there were serious comments on the compressor and turbine, which were created by technology and the level of the 1980s. At meetings in Samara, disassembled, what should be done to improve the engine, and was designated the second phase of development. But as time went on, and further progress in building the engine was not.

After some time in the development of NK-93 returned once more, were considered the work on this engine, is scheduled program, the cost is defined as the engine of virtually every node should have something to refine, modify, and improve. This was to be done to the engine can be certified. Today, the blade design of the machine is obsolete, and now you can only talk about the possibility of using separate units and making the engine NK-93. At the same time V.Skibin stressed that the scheme itself is a progressive motor.

He continued that he had repeatedly raised the question of continued testing, and including the flight. "We have waited a long time, but the proposal was not convincing. First of all, there was no answer on what the aircraft is necessary to establish NC-93. Specific fuel consumption is very good, but the engine was considered at a speed of M = 0.75, and the airplane people have M = 0 ,8-0, 82, and then the specific fuel consumption are quite different. Engine thrust was 18 tons, but at a temperature of 140 degrees above - listed the scientific director of CIAM. - As a result it was decided to use the possibility of developments in this remarkable engine land in the industrial gas turbines, which are now very well. However, if the task of creating a new plane, NC-93 should be redone and it is clear on what sites to work. "
