Is there a front-on Closeup of the PAK-FA latest prototype? I would like to see how much of the engine show up through the inlet ...

fifth-generation aircraft to have gold-plated glass

Для самолета пятого поколения сделали позолоченное стекло - Известия
something like this..

In Obninsk NPP "Technology", which produces composite components for the fifth-generation aircraft T-50, developed a unique coating that protects the glass cockpit from the radio waves, and solar radiation. Thanks to him, the signal from the radar, air defense systems is not reflected from the cockpit, and the devices installed inside, remain invisible to the electronic systems of intelligence of the enemy.

In addition, the pilot is protected from intense radiation near the radar flying aircraft. However, for light aircraft remained transparent in the deposition is necessary to use gold.

As told "Izvestia" the chief designer of NPP «Technology» Vladimir Vikulin, make multilayer deposition of several metals - gold, indium and tin. The thickness of one layer is less than 20 nanometers (one meter billion nanometers), and the entire film - 90 nm. Despite this small amount of metal radiozametnost cockpit equipment is reduced by 250 times.

- In order to apply this coating, we have developed a special magnetron setup, which allows you to achieve a uniform coating thickness of each layer is 20 nm. Uniformity is very important - if you are exceeding the thickness will change the optical properties of the cab, if you make too thin - electromagnetic radiation will "leak" - said Vikulin.

According to him, for coating airplane lamp is placed in the autoclave from which evacuated. Then a special eletromagnitnoy gun evaporating metal "paint" coating uniformly applying the electrons on the surface, regardless of its curvature.

- The combination of gold, tin and indium were chosen by fitting the spectra, which lasted several years. During this development by Oleg Prosovsky won government - told Vikulin.

In addition to radar, gold-coated indium-olovyanoe solves another problem - protects plastic parts cockpit from exposure to ultraviolet and infrared radiation. In 2010, due to the fragility of polymer ejection seat belts when the plane lost an Indian pilot - the strap holding it in his chair, burst. With the new coating that can be avoided.

It is expected that the new "lantern" T-50 will be equipped with after the tests.

- The main task of glass cockpit aircraft of the fifth generation, in addition to the low aerodynamic resistance and high strength - to hide from radar equipment cabin. The wings and fuselage covered with composite panels that are "hiding" the plane, but through the cockpit aircraft can unmask themselves, - said Vladimir Vikulin.

According to him, the same technology to defend itself from the radiation bath of the American counterpart of T-50 - the F-22 Raptor.

The exact cost of coverage has not yet disclosed, but Vikulin noted that it costs less millilona rubles and several times cheaper than the lantern. To cover a sufficient light aircraft only two or three grams of gold.

Editor in chief of the agency profile "Airport" Oleg Panteleyev, believes that even if nanosteklo worth several times more expensive than usual, the total cost of the aircraft, this figure has not played a significant role:

- The main element of the giveaway - this is, of course, aircraft engine, which gives the location of aircraft by steel blades. But the engine is able to close the watertight panels. A cab so simple can not hide - it should be transparent. Therefore, the use of such solutions - a necessary measure.

Fourth and Fifth Prototypes of PAKFA fighter aircraft took off.

Moscow. 01/04/2012. ITAR-TASS reported. - Today, the airfield of Komsomolsk-on-Amur Aircraft proizvodstvennnogo association made "‹"‹its first flight on the fourth and fifth flight instances of fifth generation fighter aircraft, developed by the PAK FA program. Aircraft flown by the pilots and the Hero of Russia S.Bogdan and T.Artsebarsky. During the flight had been achieved a record for an aircraft of this type of height and speed.

Nice. Wonder if pics are available along with some snippets on what's on them.

Take a look at the calendar

Hint: its the first day of april.

T-50-1 has been grounded forever。

Others are being checked for major structural problems，ie cracks in the airframe。

Yet our Indian friends are still dreaming about T-50-4 and T-50-5 on April Fool's Day。

Front side it is marked 52 and at rear it is marked 51 why?? anyone?

T-50-1 is now history。

It has been found with major structural defects and has been accordingly permanently grounded。Its parts，in this case the tail， have been "salvaged" for use on its younger brothers。 Hence the 51 tail and 52 head seen on the picture。

oh boy
well that news is a very old news in 2010 perhaps & prototypes are built to check it's durabilty & stress taking ability of the plane & aerodynamics
Of course 1st protype had developed cracks but that doesnt nt make a jack sense that all later protypes would develop similiar cracks .
WElll it's april fool's day prank ,but obviously it's fact that PAKFA would have it's new 4th protype revealed to everyone as soon as possible

Hmm, that makes sense.

4th and 5th are production models and its minimum one year away from making its first flight.

unfortunately，you won't see them flying in Indian colours before 2020。

If things go as planned it will be 2017 for the first squadron induction in IAF.

well thats not going to happen till china make its 5th gernation plane.

dont you know why Russia delayed our AC .
