    god that optics pod was a bad idea.

    Should be useful for other jets but it should have been integrated.

    I agree, it could have been repackaged into a format hugging the wing with a low RCS protrusion. This pod does not look like it was
    custom designed for the Su-57 at all.

    That thing looks like Sapsan-E had a mutant child.

    That doesn't look like the optics pod shown for Su-57 initially.

    Integrated one makes the jet even more costly and is most of the time useless as strike role is for su-34. It also increase the weight which is an important factor for such jet.

    A pod can be removed when not needed and shared so they need less of them.

    That's not a targeting pod

    It's a set of cameras to record weapon separation tests

    that would definately explain the odd placement of the cameras on the side of said pod.

    Does this device have a specific designation name or we dont know?

    So we will finally see r-77M ?

    Well, they will receive the first su-57 in few month so r-77M should be already tested.

    In one part he compares the Su-57 with the Su-27/35



    About a year I did not fly the su-27, and then had to fly on it. Already flying up, I felt it's too heavy and completely unnatural, as if I flew on bomber, not on fighter.

    but the progress of the 5th generation compared to 4th serious enough even from the point of view of the control system. To describe in the simplest terms, with all my deepest respect for the su-27 I can say that compared su-35 and T-50 is like a truck and a car. All in all, again, I stress, my deepest respect for the su-27, which similarly differs from the aircraft of the 3rd generation such as su-17 and su-24 as a passenger car from a truck.

    I presume that he's talking about the baseline Su-27 though, not the Su-35 with its fly-by-wire systems, TVC and advanced controls, avionics.

    Hence the second last sentence.  He compares the Su-27 to Su-35 as a Truck vs a Car.  So Su-35 is flying car while the Su-27 is rather hard to fly with thus a truck.

    But damn the Su-27 was a fantastic aircraft even today with its upgrades.

    No, looking at the quote again; he's comparing the Su-35 and Su-57 to a truck and a car respectively.

    Which sounds unbelievable. Was he a Su-35 pilot?

    Look at the original Russian text:

    при всем моем глубочайшем уважении к Су-27 могу сказать, что в сравнении с Су-35 и Т-50 — это как грузовик и легковой автомобиль.

    He is lumping the Su-35 and T-50 into the car category and Su-27 into the truck category. It is obvious he has flown the Su-35.

    Bogdan is one of the main test pilots of Sukhoi. He flew anything Sukhoi made (newer stuff, of course). If Sukhoi would produce a toaster he could fly it. Very Happy

    I guess what he is saying is that the new plane is easy to fly, which is not hugely surprising considering all the AI and computers they are using to make it simpler to fly and operate.

    Keep in mind the basic Su-27 required a lot of work from the pilot to do most things... using air to air missiles is largely a manual thing... one of the largest displays in the old cockpit was a clock so the pilot could illuminate the target long enough for the missile to reach the target... it was pretty much the same as the first model MiG-29s and indeed MiG-23s and MiG-21s, but of course the MiG-29 and Su-27 were huge aerodynamic steps up from older aircraft, just like the much more computerised and updated Su-35 and MiG-35 and Su-57 will have greatly improved and simplified and automated everything from navigation and self defence to using weapons and just simply flying around.

    Speaking of new, the dolts of the Indian Air Force has released a picture that shows that the cockpit of the Indian Navy's MiG-29K is far superior to that of the MiG-29UPG. As a reminder MiG-29Ks were ordered in 2004 and Mig-29UPGs were ordered in 2010. Laughing Laughing

    Doubt it, it's just camera

    Everything has a designation code... this isn't the only weapon release camera the Russians or Soviets used, though sometimes they are literally conventional cameras attached to parts of the aircraft... particularly on helicopters to look at weapon separation and rocket exhaust effect on other weapons mounted and engine intakes.

    Speaking of new, the dolts of the Indian Air Force has released a picture that shows that the cockpit of the Indian Navy's MiG-29K is far superior to that of the MiG-29UPG. As a reminder MiG-29Ks were ordered in 2004 and Mig-29UPGs were ordered in 2010.

    India very carefully negotiates all costs and spending with their orders... if one cockpit looks less modern than another it is because the role that aircraft was expected to perform didn't require anything better or they weren't prepared to pay for better.

    I don't think multifunction displays or head up displays showing speed and navigation cues are that critical in a car, and to be honest, while there are a lot more indicators in an aircraft the main feature of a multifunction display is actually to hide information that is not currently important rather than to display absolutely everything like conventional displays do.

    I would say the MiG-35 and Su-35 and Su-57 will be much better than older model Russian and Soviet aircraft, because they not only display the information better, but that they also take care of a lot of thing the pilot used to have to do manually before... meaning he can concentrate more on other higher level things.

    MiG-29UPG is modernization of original MiG-29 to Indian standard of MiG-29SMT. MiG-29K is based on MiG-29M. Both have the same radar and IRST and Indian RWRs and ECM equipment.

    I have heard the izdelie 30 uses a plasma ignition system. Does that mean its rear can absorb RF waves for better stealth? Sorry if this sounds comical but I am being serious.

    I suspect it means it uses a very very high temperature system to ignite the fuel which makes it more likely to be able to effectively restart the engine in case of a stall or flameout over a wider range of flight conditions.

    For instance some jet engines can be restarted over a band of different flight speeds and/or altitudes so the aircraft needs to speed up or slow down or descend before it can try to restart the engine.

    I suspect a plasma starter system increases the range and envelope where the engine can be restarted...

    Do you think Su-57s can team up to get a better resolution at longer ranges against stealth targets for their radars?

    I've read that french and americans are working on something like that. For exemple a group of 4 rafales makes their radar work togather and they have a better resolution and can see LO targets.

    It's not just making their radar work on the same frequencies but something more complicated with signals being encoded. I can't remember the name of that technology but it's a good power up for their air forces if they manage to do that.

    It is more relevant for Su-57 and for Anti stealth doctrines compared to US planes.

    The MiG-31 has been able to link with other MiG-31s to create a virtual radar that can cover airspace from ground to near space across a distance of up to 1,200km or so... with a depth of 2-300km... mainly with the purpose watching for incoming bombers and cruise missiles.

    The ground based Nebo system combines three different radar types to track stealth aircraft combining the useful effects of Ku and Ka band, L band, and VHF band radars to maximise performance and minimise weaknesses.... certainly having L band wing mounted antenna and forward looking Ku and Ka band radar should allow excellent forward looking performance against stealthy targets, and with their data links and communications they are working on it should be possible to combine the information generated by a range of radars and sensors to form a picture of the airspace around these aircraft.
