"The Defense Ministry will get the first serial-produced Su-57 with the operational first-stage engine on the single military output day in December this year and four more such planes in 2021," the source said.
The new fighter’s delivery rate will eventually grow to 15 aircraft a year, the source said.
"As a result, the contract signed in 2019 on 76 Su-57s through 2028 will definitely be fulfilled on time," the source stressed.
The deliveries of Su-57 fighters with the second-stage engine are set to begin in 2022, the source said.
The Su-57 is a fifth-generation multirole fighter designed to destroy all types of air, ground and naval targets. The Su-57 fighter jet features stealth technology with the broad use of composite materials, is capable of developing supersonic cruising speed and is furnished with the most advanced onboard radio-electronic equipment, including a powerful onboard computer (the so-called electronic second pilot), the radar system spread across its body and some other innovations, in particular, armament placed inside its fuselage.
The Su-57 took to the skies for the first time on January 29, 2010. Compared to its predecessors, the Su-57 combines the functions of an attack plane and a fighter jet while the use of composite materials and innovation technologies and the fighter’s aerodynamic configuration ensure the low level of radar and infrared signature.
The plane’s armament will include, in particular, hypersonic missiles. The fifth-generation fighter jet has been successfully tested in combat conditions in Syria.
Besides the dream of adding photonic radars(KRET, RTI and VEGA claim this) it would be cool if the radar shadow fixation calculation gets added to software of the 2nd variant Su-57 as a tracking feature and stealth transparency metamaterial than can also be used on antennas.
" The metamaterial is a metal-dielectric hybrid scatterer based on a well-defined magnetic dipole moment with simultaneously suppressed electrical response, resulting in minimized total scattering. The first of the possible applications of the new coating will be STEALTH technology for military and civil purposes - in order to hide various elongated objects, such as aircraft landing gear, antennas and various sensors, ship masts and airport towers. If the task of hiding these objects from enemy radars is trivial, the developers emphasize, then the task of electromagnetic compatibility of antennas on satellites is very important so that some antennas do not affect each other. And this will only be possible if they are invisible. The method will help to hide the buildings of airports, operator towers, so that they do not interfere with radars and communications with pilots. In addition, the development will find application in the so-called "Magnetic light" tasks, i.e. where it is necessary to amplify various magnetic phenomena: in nano-antennas, nano-lasers, etc. The new metamaterial is completely transparent to electromagnetic waves due to the excitation of "anapoles" in them. The metamaterial has an artificially created periodic structure. Applying the idea of dipole moments, it was possible to develop a generalized invisibility theorem and turn it into a mathematical model Sample of a superconducting metamaterial. The electrical moment excited in the system at the moment the radar signal hits it is compensated by the toroidal moment. Anapol (from the Greek an - negative particle and polos - pole) is a non-radiating source or scatterer, which is capable of emitting vector potentials in the absence of radiated electromagnetic fields, as well as scattering vector potentials in the absence of fields. A fundamentally new version of stealth masking, which will allow the radar signal directed at an object not to be reflected, not absorbed, but simply to pass through, as if there was no object. This masking method is based not on creating a cloaking cover, but on changing the configuration of the entire object system."
"The stealth disguise used today is far from perfect. Such a coating is expensive, and for more efficient operation it needs the most flat surface - as a result, in airplanes, for example, you have to sacrifice the aerodynamic characteristics of the device. At the same time, the absorbed signal still creates a "shadow" - a small response that can be detected by more advanced location systems."
"The Russian Institute discloses new technologies for the detection of American aircraft F-35, F-22." This is how he titled the article DefenseWorld.net, it says that Russian scientists managed to present a new model for calculating the radar shadow of a moving object. A new way of detecting stealth technology has been discovered. The method is based on the analysis of the radar shadow (RLT) of the observed object by synthesizing the aperture of moving objects arising at the stage of terrain mapping. It is reported by DefenseWorld.net. American stealth aircraft F-22 and F-35 evade radar in two ways: 1) the shape of the aircraft, which reflects radar signals away from enemy radar, and 2) a special coating that absorbs signals.
The considered method is simple to implement and can be used as an additional feature in the selection of moving objects. The detection of stealth radar by means of angular reflection is more significant than the absorption of the RPM. But it is not yet clear the effective configuration of the locators, whether it is feasible with modern technology in the form of an accessible combat uniform. A new method of selection of moving objects (SDO), manufactured using stealth technology, is presented by JSC "Radio Engineering Institute named after Academician A.L. Mints "(JSC RTI).
As part of the development of a new method, JSC RTI assessed the possibility of using the analysis of the radar shadow by synthesizing the aperture of moving objects that arise at the stage of terrain mapping. “The developed method of observing“ invisible ”objects made using stealth technology is the result of the joint work of several educational institutions, enterprises of the military-industrial complex and small businesses. We have achieved viable cooperation, ”said Kirill Makarov, General Director of RTI JSC.
This method is of high practical importance. If, along with the image of an object shifted along the bearing, its shadow is observed, then the direction finding should be made along it. In this case, the difference in the bearings of the radar image of the object and the shadow carries information about the speed of the object. The new method reduces the level of direction finding errors. The proposed block diagram of a multichannel synthetic aperture radar (SAR) provides simultaneous formation of a high-resolution radar image, selection of moving objects on board a small-sized aircraft, and data reception and transmission to the control center in real time."
