Prospective complex tactical aircraft (PAK FA) is in the sky.These are new machines and devices, composite materials, radar systems and engines created for Russian enterprises.



Su-47 Berkut - combat aircraft with swept back wings. In the 90 years he mistakenly called fifth-generation fighter. Many countries have tried to make a similar, but the problem of destructive load on the wing could be solved only in Russia.





"It was a unique work, but unfortunately he did not go in the series. However, this aircraft was manufactured, such an aircraft with wing-swept composite no one else has," - said Vladimir Vikulin, General Director of the CVTS " Technology.



"Berkut" exists in a single copy, is now flying laboratory for testing new technologies. In Su-47 has no future, but he gave life to another plane - the fifth generation fighter with the code T-50.



"Companies within the Group, producing products and components for the fifth generation fighter aircraft - about 70% belong to the PAK FA aircraft, which made its maiden flight", - says Director General of Civil Rostekhnologii Chemezov.



After the first flight of talking, if not the superiority of the Russian aircraft over the U.S., exactly the parity in the air. Who will flog the first - the main issue in modern air combat. Technology invisible "stealth" means that the plane should emit as little as possible heat and carry a minimum of metal. So close the nozzle and the blades of engines, using composite materials.



"On foreign prototypes - the F-22 Raptor and created the F-35 - Composites are widely used, more than 40%. And we are sure that in our forward-looking fighter use of these materials will be no less a figure", - notes Nikolay Vymornov, Chief technologist NPK "Composite".





At the Scientific-Production Enterprise "Technology" specially for the fifth-generation fighter developed a new carbon fiber material.



"We have created a composite snap-in: it does not snap out of invarovyh metal alloys, which the West is very expensive. Invarovyh of Why? Must be very low coefficient of thermal expansion. A lightweight composite tooling, corresponds to the ratio and quality of the products to them better," - explains Vladimir Vikulin.





In the battle of two equal stealth to win the one who has a better radar system.



"When it comes to that, the sigma of our aircraft and the perceived enemy in the meter, we can effectively deal with such aircraft, even winning some dueling situation", - said Vladimir Zagorodnii, Chief Designer, Head of NIIP named after V. Tikhomirov .





Sigma - a measure of invisibility, the magnitude of the reflection beam from the enemy planes. The smaller the sigma, the more difficult to detect aircraft.



Vladimir Zagorodnii lovingly examines the brainchild of his team - radar for the new fighter. There, over four thousand small receiving-transmitting elements, such technology is called AFAR - active phased array antenna.



"AFAR - the eyes and ears for the airplane, the more so for the fifth generation. It differs from passive antennas so that each channel antennas are located on the transfer of power amplifiers," - says Oleg Alexeyev, deputy chief designer of NIIP named after V. Tikhomirov.



Passive antenna control rays can not, for scanning and tracking turns himself locator. At the fifth-generation fighter radar motionless, looking for and accompany themselves goal rays. If spotted by the enemy, no aerobatics not help, get out of the zone of such a radar is extremely difficult. And the T-50 will install five radars - one in front and two on each side with a phased array radar and a pair of UHF in the wings. Now at the Research Institute of Instrument Design Tikhomirova just experienced Maintenance Mode 20-30 goals. The potential for AFAR, say developers, yet for decades to come.



"The fact that a price today, I have not seen a Raptor, or in the F-35", - said Vladimir Zagorodnii.



American F-22 until the T-50 was considered invincible. His ideology - to be hardly noticeable for ground radar. Ideology "Sukhov Fighters - Raptor detect earlier and more effectively fight in close combat. To improve the maneuverability of fighter plane equipped with new engines with thrust vector control.



"He has another attraction, and other adjustments, applied a number of fundamentally different design solutions. But the main thing - it is a different regulatory system," - says Ilya Fedorov, managing director of NPO Saturn, Deputy Director General of the Criminal Code "JDC".



The new engine Saturn - the development of the power unit with an index of 117, is the heart of Su-35. The engine of the fifth generation is being improved, resources and traction. Although already in the first flight of the T-50 has demonstrated its power - the rise was almost vertical. And now a fighter ready to go at supersonic speeds without the Fast and the Furious.



"This plane can go out on such a regime in the process of refinement and testing. But it is a question for the plane, but not to the engine. The engine provides all of this," - says Ilya Fedorov.



The plane took off from the airfield in Komsomolsk-on-Amur - the first prototype. His image can still change. But those devices, components and assemblies for the T-50, which have already been tested on the ground, soon to rise in the air on the new prototype.



"Commence negotiations, and in the near future, I hope, will sign an agreement establishing a joint India-Russia aircraft of the fifth generation. And this aircraft will be jointly sold by us abroad", - said Sergei Chemezov.





And perhaps in the future, T-50 and F-22 converge in a training battle, and it becomes clear who now reigns in the air.
