Military expert Linchuan Liu gave a lengthy interview where motivated the need to buy China Russian Su-35 fighters, reports now mil.news.sina.com.cn (material provided with some cuts — approx. «VP»).
According to the views of professional …, Su-35 has stealth capabilities and the ability to make a supersonic cruising flight, but has super maneuverability thanks to the use it 117S engines with thrust vector control. Then he surpasses even what third generation fighter (meaning fourth generation — for the convenience of further understanding the global system will be used to systematize generation fighters — approx. «VP»).
Su-35 resettled massive airborne radar «Irbis» with a passive phased array. Our homeland claims that this radar is able to find the target with the ESR (effective scattering area) 0.01 m. m at a distance of 90 km. U.S. announced that on some angles EPR F-35 is a given value, ESR F-22 — 0,001 m. m (company Lockheed Martin has reported on the value of the EPR front of the F-22, equal to 0.0001 m. m — approx. «VP»). But in some countries, there are reports that the EPR F-35 is 0.05 m. m, F-22 — 0.01 m. m If the Su-35 radar detects targets with radar signature of 0.01 m. at a distance of 90 km, at such a distance that it can find F-22 or, at least, F-35. So makarom advantage of American fighters in stealth technology may be offset by a significant degree.
Compared to the Su-27 warplane new functional Su-35 4 + + generation resettled engines with significantly greater thrust, besides having a divergent nozzle. FBWCS (wire control system) Su-27 has low and «poor opportunities,» Su-35 resettled significantly improved digital FBWCS. Has upgraded fighter avionics as electrical monitors («glass cockpit»), which significantly increases the level of pilot situational awareness and improves cab ergonomics, increased internal fuel in store with the possibility of suspension of external fuel tanks significantly increases the range and combat radius. In addition, the Su-35 EW resettled new systems. In contrast, the Su-27 has insufficient ability to attack ground targets, which significantly limits the flexibility of its combat deployment.
China is very interested in getting 117C engines, it will be for us an additional benefit. Our homeland will not put these engines without the Su-35, it is necessary to realize. China as before needs Russian engines and do not look down on them.
Also there is a lot of enthusiasm to the radar «Irbis». Currently, China has cleared the creation of technology radar with active electronically scanned array (AESA), but this does not mean that we refuse to look at the foreign developments. «Irbis» has unique things first advanced software techniques. Russian equipment is often made very rough, but differs decent performance features. Familiarity with «Irbis» will help us to realize the development of major technologies in this field, we have to learn the strengths and feeble hand of foreign developments to make their systems better.
In the arsenal of the Su-35 are long-range missiles with ramjet engines (ramjet). We are also developing such missiles, but why not look at other people’s creations, if possible?
Can the Su-35 to upset the balance of power in Northeast Asia? China pursues an independent foreign policy and no one is threatened. We test fighter J-20, it also does not threaten the military balance in Asia. Yet, some countries invaded Chinese territorial waters. Japan has a defective mind, and always says about the Chinese threat. For this country typically adulation Europe and America, Asia and disrespect for contempt for China. This mindset persists.
China buys Su-35 as in the development of our promising fighter J-20 and J-31, there were huge difficulties? Acquisition of the Su-35 is necessary for the rapid buildup of the PLA Air Force power, because there is severe prerequisites for a major war with Japan. In the development of fighter fifth generation China goes step by step. Soon J-20 will have new engines with thrust vector control, maneuverability and acquire supersonic cruising. According to its characteristics it is certainly superior to the Su-35.
J-31 has the least powerful radar than the Su-35, simply because of the fact that the area of the antenna field in the bow of the fighter less, but such a requirement is not placed. Later fighter get more massive engines and will be able to make a supersonic cruising flight.
Tests new fighter takes an average of 6 years before he entered service military aircraft. We naturally intensifying flight test schedule, cycling new layouts. But you can not dramatically reduce the time, it is a law of science. Some commoners believe that once flew fighter, it must adopt and criticize «intelligent patriots» who are better versed in their technical issues.
Maybe Russian fighter T-50 PAKFA technologically advanced than the J-20 and, of course, better than the Su-35. But the fighter still immature, pass the tests, still not conducted tests guns. If we buy or join the T-50 program there, we will lose autonomy in the field of armaments. I am sure that the choice of the Su-35 was correct, and to some extent it is able to withstand the F-22 and F-35.
Objectively speaking, low profile assigns a huge advantage in a dogfight, most importantly — reduced detection range of the enemy. F-22 is able to fly at supersonic cruising, this its 6 air combat missiles have a higher initial rate, the U.S. Air Force rely on distant rocket attacks, but the Su-35 will be severe competitor.
In superagility Su-35 combat a large sense. Many experts believe that the maneuver «Cobra», performed by the Su-27 fighter, has no practical implementation in a dogfight. Engines of the fighter does not have thrust vector control, in the case of a missile launch or firing of guns plane can lose maneuverability and fell into a tailspin. Because we have so far not beheld as Russian Su-27 performing this maneuver, using a weapon. Prior to implementation of the «Cobra» aircraft must slow down to 400 km / h, which is significantly less high subsonic speeds, which are commonly used in the management of air combat. Will take time before the fighter returns to perform energetic maneuvers and score the desired speed, because the Su-27, the advantages of this maneuver can not be applied in full. Another thing is the Su-35, Curb significantly stronger engines. The presence of thrust vector control allows the fighter to not rely on the classical aerodynamic controls that are ineffective at such speeds, there is no danger of breaking into a tailspin that will allow the airplane to launch rockets and conduct fire a cannon. So Makar, terrific agility and maneuverability of the Su-35 will allow excellent use this maneuver in a dogfight.
