Su 57 QWIP IRST
******************

The 101KS-V is also sometimes referred to as the OLS-50M which is an advanced IRST based on the revolutionary Quantum Well Imaging Photodetectors (QWIP) technology. These new generation IRST systems have the potential to operate in a much wider spectral bandwidth that includes the very longwave 15 micron band to detect very cool targets. They can also be made to operate simultaneously in several different bandwidths. . This sensor can detect, identify, and track multiple airborne targets simultaneously.

Su 57 s QWIP IRST OLS 50 M can detect stealthy aircrafts at greater distance than its radar. QWIP is the most advanced technology in the field of IRST. It can simultaneously detect and track of aircraft exhausts, jet-plumes and missile flares. Russia has decades of experience in the integration of infrared sensors into its weapons systems, and QWIPs could well become the primary sensor and radar the secondary for its anti stealth missions.

The IRST housing is turned backwards when not in use, and its rear is treated with radar-absorbent material (RAM) to reduce its radar return. And its glass cover also has a thin film of Radar deflecting materials (Indium – tin Oxide)

No matter what RAM treatment you apply to PAKFA the entire airframe design is non-stealthy from all angles, especially from the front. It will be an easy target for AEASA radars with agile beam forming and frequency hopping capabilities.

Wrong assessment , Russian philosophy is completely different than western , they are developed their own tactics to counter F22 like stealth aircrafts. They developed Su 57 as a counter stealth aircraft. Su 57 has enough stealth to delay detection and when the Su57 appears in enemy stealth aircrafts Radar the stealth aircraft will fell in to the sensor coverage of Su 57 and the advantage in Stealth may not help the adversary , with its superior kinematic and long range Weapons Su 57 can defeat Other aircrafts .

Judging from the frequency of rejection its getting from more serious customers I'd say the Russians had been caught with their overadvertisement. Everybody is buying older design Su-35 over Su-57. It tells a lot more than Russian propaganda on Su-57.

F-22 equalizer huh? Now that's funny... (I'll refrain from making a maniacal laugh to maintain comity..).

I Agree, they designed it to reach closer enough to pull the stealth jet into WVR. Its a hook-n-pull jet. It was designed this way. Its radar and sensor suit has no match, awareness about the area, was built into it heavily through it.

I mean its now FOC, so they didn't put billions of there money into a program that doesn't bear fruits.
Its ECM capabilities are on paper also fine.

From a video Chinese tried to create CGI to demonstrate the working . But you know they are Chinese , it is not a rail system but an ejector, R-73 family uses rails. The door doesnt open like that, it opens towards the intakes.

Su-57 to get electric drivers.


The hydraulic systems of the fifth-generation Su-57 fighter jet will be replaced by electric engines to decrease the signature, increase maneuverability and simplify maintenance. Su-57 with new controls is expected to take off in 2022. Experts believe the modernization will increase survivability, the Izvestia daily writes.

The prototype of the upgraded Su-57 has to take off for the first time in mid-2022, defense industry sources said. The engineers design electric drivers for all controlling surfaces of the fighter jet. They will increase maneuverability and provide maintenance advantages.

Trials will take at least two years. They will test flight characteristics and electromagnetic compatibility of the new equipment. The system has to be reliably protected against internal and outside disturbances and lightning.

Transition to electric drivers is a sophisticated task. The result will be astonishing in case of success, experts said. The absence of hydraulic pipes and mechanisms makes the jet lighter and simplifies maintenance, as it is easier to replace parts. There will be no liquid leaks and toxic oil. Electric engines are lighter and smaller.

Test pilot and Hero of Russia Oleg Mutovin believes electric drivers will increase survivability. “An aircraft maneuvers in flight due to the movement of the so-called controlling surfaces: ailerons, stabilizers, rudders, etc. Before the jet era, pilots could control the aircraft without boosters. In the jet era, the payload and speed increased and the strength of pilots became insufficient. Designers began to introduce hydraulic boosters. It is difficult or impossible to control a modern jet without them,” he said.

Modern jets are equipped with sophisticated and powerful high-pressure hydraulic systems. Pipes have to be installed in the wings and fuselage for the liquid. They occupy a major place and are vulnerable in combat. “Pressure exceeds 300 atmospheres in some modern jets. A pipe damage exhausts the liquid in seconds and the booster breaks down. Unfortunately, I have experienced the situation,” Mutovin said.

Cables replace pipes in case of rapid electric drivers. They can have standbys in various places and damage will not break down the drivers altogether. No flammable and toxic liquid is necessary. The weight of hydraulic pumps and pipes is saved.

The US and European civil and military aviation is designing the so-called More Electric Aircraft. Electric drivers replace traditional hydraulics. It is an advanced approach.

US F-35 has progressed a lot. Its key advantage is a mixed electric-hydraulic system. American designers refused to merge the hydraulic systems to manage the controlling surfaces. Each fin element, be it a rudder or flap, has an independent hydraulic contour managed by an electric driver.

A complete drop of hydraulics is even more promising. The Swedish SAAB which produces JAS 39 Gripen considers electric drivers for its projects.

The approach is used in advanced civilian aircraft. Boeing 787 Dreamliner has completely electric brakes and chassis instead of hydraulic. They are lighter and exactly control all parameters in real time, including the wear and tear of brake pads.

Su-57 for the first time took off in early 2010 and is undergoing final trials. The fifth-generation jet has not been accepted into service yet, however several upgrades are already in store. In particular, the platform of the jet will be the main one for Russian combat aviation in the coming decades. Therefore, the aircraft will undergo numerous transformations.

The fighter jet has to be powered by the second-phase engine. At present, the first serial Su-57 have AL-41F1 turbo jet engines known as item 117. Flight trials of the latest fifth-generation engine known as item 30 are underway.

Deputy Defense Minister Alexey Krivoruchko said the new engines would consume less fuel and the life cycle would be less costly. The fighter jet will be able to make long flights at supersonic speed without a boost. The powerful engines will satisfy all the energy needs of a more electric aircraft.

After trials and batch production, the new engines will be installed in available Su-57. Together with electric controls they have to display full capabilities of the jet, the Izvestia said.

The soviet sell their aircraft as well so that argument is null, to say Soviet have no propaganda is just being dishonest. And yes, Mig-23 MLD is a better fighter than Mig-23 MLA, it is an upgrade of MLA after all so not really a big surprise there. The key point is that Soviet also admit Mig-23 MLD maneuverability is inferior to F-16 and F-15, and we don't really have an EM chart of Mig-23 MLD to prove otherwise, I will take their words for that.
If western source don't accept air to air lose, then why are they so comfortable telling stories about the F-18 that got shot down by Mig-25? seem to me that they are quite open about it

Also Zero was not better than Hellcat, Zero could turn better, but the much better acceleration and speed of Hell cat could allow it to get out of the engagement range of Zero's cannon very quickly, so every time Zero get into Hell cat's tail, Hell cat pilot can just zoom aways. Then the armor of Hell cat was better, so if they were go head to head, then a small burst from Hell cat cannon will make Zero go down in flame. Now you gonna argue that Mig-23 MLD can zoom climb faster than F-16A so it can do the same thing that Hell cat did to Zero. Well no, because in WW II, the main aircraft weapon were 0.5 cal cannons and 7.62 mm machine gun with effective range any where from 300-600 meters, it is very easy to just accelerate outside that range, and if your aircraft were decently armored, then you can tank hundreds of cannon and machine gun round with no issue. It is no longer the same situation when F-16A and Mig-23 MLD were in services, the main close range weapon were IR missiles and SARH missiles, you can't out-accelerate them and get outside of the engagement range, and you certainly can't tank their warhead. Secondly, like I said earlier, Mig-23 super good acceleration at high speed came from the fact that it can fully sweep its wing back at 72°, it is basically an arrow at that point, however, doing so will reduce CL significantly, it will turn much worse. So you can either choose decent turn capability when wing sweep is at 16-33-45° or quick acceleration when wing at 72°, but not both at the same time, and it take sometime to change the sweep angle . Unlike F-16A which have both super good STR and acceleration at the same time

F-16 is not better in everything to MiG-23MLD, wings are not set for all speeds, F-16 was designed for 0.7-0.9 mach ranges, at higher speeds the MiG-23 can fly better, is it better? no because the MiG-23 can not supercruise thus it has to fight at lower speeds, in general terms what the manual said is fly faster than the F-16 because at those speeds the F-16 will fly worse, but not at the speeds the F-16 has better performance or handling.

The MiG-23MLD attacked by F-16 in Afghanistan knew it, fly faster the F-16 will not fly better, it saved the MiG-23MLD several times.
Same applies to any aircraft, any aircraft has to bring the opposition where it has more advantages, in Bekka Valley, the F-16 flew in a way harder for the MiG-23MF to overwhelm the F-15 or F-16, in Afghanistan they flew in a way the F-16 could not succeed, and remember Pakistan admitted an air to air kill regardless is fratricide, the soviets do not admit any MiG-23MLD loses on air to air.


You will need good evidence to prove the MiG-23 were downed by F-16 and that evidence does not exists

Что такое анаполь? Новый метаматериал для стелс-покрытий

Засекая объект при помощи радара, на него посылается волновой сигнал, и по отражению волны определяется его местоположение.

“An international team of scientists from NUST “MISiS” and the Polytechnic University of Turin (Italy), in the framework of cooperation on the ANASTASIA project, have proposed a fundamentally new variant of stealth masking, which will allow the radar signal directed to the object not to be reflected, not absorbed, but simply to pass through, as if no no object. This method of masking is based not on creating a masking coating, but on changing the configuration of the entire system of the object.”

Stealth by transparency, but for it to work they have to master quantum computers next.

Russia’s fifth-generation Su-57 fighter jet is working on the use of an unpiloted mode during tests, a source in the defen?e industry said. “The T-50 flying laboratory is testing an unpiloted mode. A pilot is in the cockpit during a flight but is just controlling the operation of all systems”, the source said. The Sukhoi Su-57 (formerly known as PAK FA, or T-50) is a cutting-edge fighter jet that performs the functions of a strike aircraft and a fighter and is capable of destroying all types of air, ground and naval surface targets. The Russian Defence Ministry placed an order for 76 Su-57 jets during the Army-2019 International Military and Technical Forum. The warplanes should be delivered to the Russian Air Force by 2028. A total of 13 jets have been made so far. Previously, the United Aircraft Corporation (UAC) revealed the story behind the name of the aircraft. Su is a reduction of Sukhoi, the surname of a famous Russian aerospace engineer. Number 5 stands for the fifth-generation of Russia’s fighter jets, while seven is a lucky number for the Sukhoi Design Bureau.
