Why do I compare the F-35 aircraft c Russian 4th generation, not the F-22, whose flying characteristics significantly better? An anonymous creator, not waiting for the continuation of my article about the aircraft fifth generation just picked up and finished writing it himself. And quite successfully highlighting those flaws F-22 that I missed earlier. Although this does not give the creator of links to the source of its own material, I'll do differently. I quote him all the rules of journalistic ethics, in other words, with reference to source:
"I nepoprostu so much attention to features of the F-35 and compared it with specifically modern aircraft of the previous generation. Fact is that the" super-fighter "F-22 at its own cost quite crazy has versatility! Other words, is not a universal machine. A closer look reveals that the impact potential of the F-22 in "stealth" is close to zero.
In his cramped internal weapons bays just a couple of moderate climbs 1,000-pound (454 kg) bombs or eight really quite toy 250-pound (113 kg) bombs — two times less than the cheaper F-35, which is also the potential impact South American professionals seem quite lacking.
Transition to external load on a theoretical level could seriously increase the number of strike weapons — but in-1's, with all this, the F-22 completely loses its low profile and is no longer superior to anything available in general-purpose aircraft of the 4th generation, like the Su -34 and Su-35. Outside significant amount of suspension arms dramatically raises the drag of the F-22 and makes it impracticable flight at supersonic speeds without using afterburner engines. Because, as seen from above Poster, Americans and do not expect to use external load F-22 strike weapons (bombs). More than that — they generally do not seriously expect the potential impact on the F-22, since up to now the only weapon, the F-22, which can be used against ground targets — these are the same small bombs with a personal homing coordinates GPS, applicable only for point blows to advance explored motionless objects. "
At the theoretical level, the implementation strategy planes 5th generation is the idea of "first seen — the first shot — the first kill." In other words, he has to get close to the distance inconspicuous start their own rockets and launch them before they saw him. Specifically to reduce the radar signature of the aircraft. In radar visibility is determined by the reflective capabilities — [url = http://] effective dissipation surface [/ url] (EPR). The larger the surface, the greater the return signal and, as more opportunity to see him. You can make an analogy with a flashlight and a mirror placed a few meters away from the light source. Radar shines his flashlight as a transmitter and a receiver detects its signal reflected from the mirror. The sensitivity of the radar receiver detects a low level of the reflected signal is detected. Because the more the mirror surface, the greater the reflected signal and the greater the distance can register the reflected radar beam. Sensing this Makar is defined by 3 parameters — radar transmitter power, receiver sensitivity radar and an area of the reflecting surface "mirrors" — ESR. With the help of radar absorbing materials and scattering characteristics of geometric shapes plane fifth generation fighters significantly lowers the latter figure, but does not make it equal to zero. We present below the comparison table EPR different planes for Western analysts estimated:
Most of the founders of publications about the stealth aircraft are specifically related to their development, because the data in the table are based on similar publications, of course, and therefore not entirely impartial. Independent research on certain stealth aircraft in fact. Just flying the F-117 in Iraq and Yugoslavia, have enabled our military spice to evaluate the effect of "new" technologies Yankees. And estimates of Russian military professionals Modern technology made by programmke "Stealth", can reduce the effective area of the cross section (RCS) of aircraft up to 70 percent compared with conventional aircraft schemes. With all of this detection range of such stealth aircraft will be reduced only to the third part, because detection range is proportional to the fourth power of the magnitude of the EPR. The Western experts they say about almost thousandfold (!) Reduction of the EPR. Very impressive. But in terms of the distance detection means its a decrease of approximately 5.6 times. So if ordinary aircraft detectable by radar at a distance of 300 km, then on the same radar is the "invisible" from the "stealth" will be fully visible at a distance of 54 km. It is not so very impressive, but still fully meaningful.
There are various estimates of dueling abilities Raptor with our modern aircraft. There are quite optimistic, like such:
So, it makes sense to compare the "dueling" abilities radar systems of the Su-35 and F-22A «Raptor." Russian car equipped "Irbis", can find a target with RCS of 0.1-0.5 m2 (ie the "Raptor") at a distance of 165-240 km. South American fighter "sees" its own enemy with a significantly higher (about 1 m2) EPR also at a range of 200 km. So Makar, nearly invisible "Raptor" with its own AESA radar on board of the complex has no real advantages to the upgraded "dry" in a dogfight missile for "vnevizualnoy 'range! And this is one of those important characteristics, the undoubted advantage of any "Raptor" over at least what similar machines counted South American military.
AN/APG-77 radar is an active phased array antenna rounded width of about 1 m, consisting of approximately 1,500 solid-state transceiver modules (each module length — 70 mm, height — a few mm), which is used in the technique of whole integrated circuits microwave. In order to reduce the visibility provided passive radar modes, provided little chance to catch signals in active mode radar. Most large range of detection of air targets — 270-300 km.
How big is the purpose of the Su-35? It was argued that there used stealth technology and it can be really lower range of detection to 200 km. About our radar "Irbis" installed on the Su-35 in Wikipedia [url = http://] approved [/ url]:
"N035" Irbis "- Russian aviation compact radar with a passive phased array design NIIP. Development N035 for fighters crotch 4 + + generation was launched in 2004 and completed in 2006. Power radar radiation — about 5 kW. Mechanical scanning is gidroelektromehnicheskim drive. detection range targets like fighter (with EPR 3 m ²): up to 400 kilometers. "
"Russian company" Fazotron-NIIR "finished developing a new airborne radar" Zhuk-AE "for the MiG-35 with an active phased array. According to the director general of Vyacheslav Tishchenko, it first made in Russia active phased array antenna. Its appearance brings our fighter to main rival — the South American fighter fifth-generation F-35. now our "MiG" is able to compete with the F-35 not only in air combat, but also in the global arms markets. "
More objectively presented test data:
"In the process of working out in the air phase on the goal of" MiG-29 "made 15 flights and demonstrated reliable supply range 60 km (LPP) and 148 km (PPP). Besides, made two flights in the mode of close combat and more maneuverable several works in the mode of the radar mapping with a resolution of 5 by 5 m (more will be 1 x 1 m). flight tests last, another was on September 17, they are no longer associated with working off the "iron" — it's over, and debugging software . As a result, the standard of AFAR FGA29 («Zhuk-AE" in the RLPK-35) with a diameter of 500 mm showed a plane-demonstrator acts sufficient distance — 130 km above the target with RCS 5 sq. m., and reliability for refusal — more 300 hours. provide the number of tracked targets — 30 (8-10 displayed on the display). "
Passion for the Yankees stealth technology has given impetus for the development of new radar techniques. To compensate for the reduction of visibility is quite increment or transmit power or the receiver sensitivity or both together. Of course, not everything is so simple — you need to take into account noise and electronic warfare. A very difficult task, but less complicated than the reduction in the ESR of the plane. In fact at the moment and there is a competition of sensitivity and power radar stealth aircraft technology — similar anti armor and projectile in the history of tank development. That is why such importance is attached to the new radar schemes, such as AFAR, which not only allow power increment transmitter, together with the receiver sensitivity, but maintain multiple targets at once, to use digital signal processing, filtering out the noise. But the most fundamental — AFAR allows you to explore in different frequency spectra. And here we come to yet another fundamental discovery. The fact that the effectiveness of stealth technology used by the Yankees are very dependent on the frequency spectrum of the radar. In the main they are designed for X-band frequencies, in which much of the work of modern radar. It centimeter wave-length. More of an old radar air defense systems using L-band frequencies (microwaves) and their South American stealth technology virtually worthless!
If the effective thickness of the centimeter-wave radar absorbing materials can be equal to centimeters, for UHF — it is decimeters and can not be implemented in practice. The effect of dispersion by the method Ufimtseva also designed to centimeter waves, scattering UHF will be significantly less effect on their geometric shape of the object is almost no effect. "It's very typical example of a liquidation of modern" stealth »F-117 in combat means Yugoslavia forty years ago. Targeting was the station ADMS" Pechora "and the launch of the rocket was with our air defense system" Square "." Yuri Snow White, CEO of NIIP Developer radar "Irbis", said not only that. He said and more than a fascinating thing to a question about the latest AESA radar, whose exhibition at the MAKS-2009 caused a sensation:
— Your AFAR will "build" aircraft, made by technology "stealth"?
— It's not AFAR is crucial. The ability to detect such aircraft is mainly depending on the type and spectrum of the emitted signal. Plus we have a few on board AFAR working in different spectra. And to make the protective coating from the waves, say, the centimeter and decimeter range once — very problematic.
Actually, this is the sentence "stealth" technology in a manner Ufimtseva and with the introduction of radar absorbing coatings. Competition radar stealth capability has almost won the radar before the planes 5th generation rose to the ranks. The new L-band radar is already advertised NIIP:
Latest AESA L-band means to set in front edges of the wings and guided this work has of course long since. But already before the working samples, this technique generally does not officially open a discussion. Moderate application developers skeptical about the development of our aircraft, "stealth" is not very lure media attention and rarely quoted. Maybe it also had its own meaning? Let rival to invest in dead-end stealth techniques, spend beyond their hundreds of billion and we spent only a few million, will create them quite useless? Only recently been advertised in the open merit on the part of the NIIP radar L-band lured the attention of Western professionals here and provoked a strong reaction:
"The program JSF is an example of a complete abstraction hardcore heads society JSF from operational reality in the world. This technology [Detection L-band] should have been anticipated 10 years ago, taking into account the development of the U.S. radar L-band AESA type systems Wedgetail AEW & C / AWACS … systems, survivability which is almost one hundred percent is dependent on reducing visibility to radar in the X-band, such as the F-35 Joint Strike Fighter, F/A-18E/F Super Hornet and F-15SE "Silent Eagle, "are now becoming visible to the fighters, carrying radar L-band, and thus Makar, become very vulnerable in combat in the air at huge distances beyond horizon."
The fact that the invention is not in the best interests of our nations and allies, who in the spirit of good will, agreed to a role in the program JSF, as is self-evident, arising out of the same 'total indifference to reality', which gave us a global monetary crisis and its more unsafe results, the global financial restructuring. The fact that the programm JSF asks configurations, does not cause vibrations. How this can be achieved is best well aware of the international group of professionals in the Royal Australian Air Force, whose advice, today, have been ignored by most of those who advise you.
