How does the SU-57 hides the frontal jet engine blades from radar?

I can't find any good photo of the intake.

        that's why there's no clear photos of intakes from supposed "production" models? coping so hard they blur photos that might reveal how uncompetitive these are?

              It's Russian math anyway and China got those stealth secrets from unsecured laptops and the Stealth Hawk wreck in Abbottabad. There's little reason to conceal that stuff because anyone who wanted to know would just buy the knowledge from Russia or China and why encourage anyone to buddy up to those two?

                Beats me, I guess they're better at theory than practice.
                Actually, they didn't even realise what they had when they came up with it. The F-117 only happened because American researchers stumbled onto the Russian paper and realised its potential.
                The Russians hadn't classified it because they thought the math and physics weren't of practical use, so I guess that's the same process that prevents them using it.

                Did they also fix their shitty airfields that make their planes require a grill in the first place?

                >Did they also fix their shitty airfields that make their planes require a grill in the first place?
                That's a jingoistic smoothbrain answer.

                Having aircraft that can use shitty airfields is superior to having good airfields.
                It would actually be way better if every US aircraft could land and takeoff from any old gravel quarry or something than to have high quality airfields.
                Both is best of course but FOD resistant aircraft is important because just like Ukraine did at the start, you can disperse aircraft and keep them alive through the alpha-strike using highways, put some under overpasses or in random warehouses and then pull them out and regroup at your leisure, including landing and refueling/rearming on random highways and shit.

                In the end it was the Wect which took the maths and developed a computer program to calculate RCS returns. Which was famously hindered by computation power and forced Have Blue to be faceted as they couldn't calculate the returns on curved surfaces.
                Indeed the Soviets had the maths, but they were lagging behind in computing. You can't design such a complex project by manually calculating every possible angle in each flat plane of the aircraft.
                >Having aircraft that can use shitty airfields is superior to having good airfields.
                Dispersed operations will slow you down after the initial days as now you have weapons, fuel, spare parts and maintenance crew spread across the country. Your logistics are fricked and you need a plan to re-centralize your aircraft as soon as it's viable.
                F-16s and F/A-18s can operate from highways. So in the short term dispersal Western fighters can handle it. The ability to conduct dispersed operations is very overrated, and even updated MiG-29 variants omitted the wing root intake grill in exchange for more fuel tank volume.

                Debatable, if that paper wasn't available it would've simply taken a few more years to develop. Relevant anecdote: in the 60s soviets had developed novel and efficient transient process simulation algorithms for loosely coupled systems like RBMK reactor cores. They managed to get them running on rudimentary mainframes, it worked so well their claims were met with disbelief when they bragged about them during science conferences even in the 70s. Canadians were developing similar reactors in parallel, they simply bruteforced through the problem by using better computers and doing more physical measurements instead of simulations. In the end the Canadian approach won, they managed to design unconditionally stable reactors unlike the soviets whose research was badly managed, constantly underfunded and rushed

                If polite company, one makes it worth anon's while to provide those images and ideally one does a bit of rudimentary searching on one's own first, at least as far as able. Anon did none of those things and didn't even make an explicit request but rather merely asked whether such things existed.

        >What is the dingus for?
        I *think* the purpose is to put instruments out beyond the body of the plane to prevent interference from the fuselage, fins and engines.

        What it definitely does is to house the L402 Himalaya ECM suite which is supposed to jam active/semi-active missiles and maybe even tracking radar. It's integrated with the N036 Belka radar in the nose and I think it also uses the Belka's LEX mounted L-band radars for the same purpose too (the Belka also has two X-band on the fuselage too but I don't know if they contribute to the Himalaya).

          This is a very interesting and detailed article on the plane and covers the Himalaya.
          https://bulgarianmilitary.com/2023/08/07/su-57-gets-protection-against-jamming-and-wiretapping-attempts/

          Unfortunately, that article appears to have one misleading picture because I'm pretty sure that the ECM unit they picture in it is actually the Khibiny. They label it as such in its filename but don't caption it in the article so you could get confused.

          >The L402 Himalayas system works on the principle of active jamming, which involves emitting powerful radio signals to disrupt and confuse enemy radar and communication systems. It also includes passive jamming, which involves analyzing and mimicking enemy signals to deceive their systems.

          Oh, I think there's a drag chute in the sting as well.

    The Su-57 is not a 5th gen aircraft. I’m not sure if it was even ever conceived as one, and not just an upgrade over existing Soviet 4th gens (ie, 4.5 gen). If it was originally designed to be a 5th gen than it’s a failed 5th gen program like the J-20, ie, technological realities of their MIC forced numerous compromises until the final result was no longer a 5th gen aircraft.

      >than it’s a failed 5th gen program like the J-20
      Incorrect. The J-20 is a fully stealthy 5th Gen fighter, the kind you'd need to get within 30 miles to be able to target it with a BVR missile and get a proper lock on. If you had actually paid attention to what the Chinkoids were doing, you'd have seen that their 5th Gen programs had achieved an enormous progress leap when Chinese hackers stole terabytes of data on the F-35 from Lockmart. It basically gave them the keys to the kingdom and all the knowledge necessary to design a 5th Gen stealthy airframe. Essentially at least half of the Chinese 5th Gen programs was developed in the US, by American engineers.

          Not only a compound needs to be maintained but it also gets in the way of other maintenance, which russians already skimp on and send the dumbest morons to do for $50/mo. Even if they covered those it's going to be torn down asap when they get to it, with one aircraft set aside for the photoshoots and showing out.

      For the millionth time, it was a prototype. The screws themselves were recessed so that they can be filled over with RAM.
