    At 900-1000 km/h you have a great relative speed, and you can use CAS missions, even circular ones, of long duration (just replace the pilot and the remote operators with shifts). at 700 km/h missions of 5-7 hours (autonomy permitting) will be the rule. With a minimal logistic management and much more economical (but much more) if you have (and so it is) a lot of data around.

    The others will have to adapt quickly.

    Well great news on two things, 1. we will get a production number estimate in 6 months. 2. it appears its an all aspect stealth drone because I think that image is showing a flat nozzle. If I had a choice on the matter between choosing the PAK-DP or PAK-DA like keeping one and dumping the other I will dump the PAK-DA because the ranges, all aspect stealth and being a carrier of Larva-MD missiles I see no point for PAK-DA and the modernized Tu-160Ms will have the long range and long distance stand offs.

    Looks much "cleaner" then the first prototype, as expected. Can someone see a camera for the operator?

    IMO it's hidden inside and pops up when activated. Most of the time it will work on its own.

    We also don't know what kind of hardware it uses for imaging - either for targeting or control. Transparency is a material property, and it is always frequency dependent. For instance, silicon is transparent in infrared. The pilot's view camera (cameras) could be in any number of locations hidden behind selectively transparent materials.

    Do you mean anyone with a brain, right? US butthurts always found it highly unlikely, due to the lack of rubles and stealth technology of the Russians

    To make their butthurt even more bitter, Sukhoi apparently implemented a major advance in the stealth technology by covering the gaps in Okhotnik's control surfaces with a flexible material, hence for the first time (to my knowledge) eliminating one of the biggest sources of backscatter of a plane...

    Is it using a new smaller engibe ? Seems far smaller than the al-41.

    Most probably Al-41 without afterburner.

    Video of the S-70 in flight shows it to have the exhaust nozzle focused to have a small aperture. So it appears not to need the
    full thrust of the engine installed in the first flying prototypes. This makes sense since it uses composite materials for the body
    and must be rather light. The small aperture of the flat nozzle appears to confirm this.

    It's a very unique flat nozzle. Unlike what I have ever seen with flat nozzles like on the B-2/YF-23 or F-22 this is very different. I think it means that different engineering principles are connected with it and I wonder what they may be. I think the Russians have a wholly unique design ideology than anyone else in the world which is why I love Russian aircraft. Rapid 3d printing of the nozzle is obviously part and an awesome means to save time and cost but I bet it's design point to other purposes as well. Cant wait to see more. respekt

    If you look at how the piping is routed, it takes air from the latter stages of the compressor and pumps them to the nozzle creating a boundary layer of cooler air around the exhaust. This means an IR missile will be much less effective unless much closer and directly behind the engine. Apparenly they are looking at his for SU-57 as well :

    https://tass.com/defense/1375517

    but with afterburners its more difficult. Its likely it will only work when in military power.

    Nah flateric over at secretprojectsuk was saying it is to test nozzle parameters.

    Aside: I just got banned for two months from that place for a ridiculously obvious joke. Was a jocular post essentially said "psshhh I knew that! Was just testing your knowledge. You (flateric) would have to be an absolute fool to think otherwise!"

    Do I need to add freaking (sarcasm) before and after every post now? I'm furious and confused all at once. I even made it over the top to obviously imply sarcasm in case someone was too autistic to see it. I had no ill will behind it so I'm shocked and angered.

    Anyways had to vent sorry mods pls no delete and sorry for talking about another website here I know some places dont like that. I just think you guys are cool and maybe someone knows people there can clue them in wtf.

    Edit: had to add a thought.

    Huhm technically that would work. But usually the way they do it, at least on normal airliners, is by using the bypass airflow instead of the compressed air. Then again, that would increase the engine's efficiency, but decrease the power-to-weight ratio, which won't work on the S-70, so they might do it differently. Interesting find mnztr.

    That is it TMA1 you are banned for life... just kidding.... Razz

    The flat nozzle mixes the hot and cold air more quickly, remember the hot air going through the core of the turbojet is compressed and fuel is burning in it so it is hot, but the front fan drags in normal cold air and blows it out the back too, and it greatly boosts thrust because it is colder and denser and in the fighter version it has lots of oxygen in it so the afterburner is more efficient in a turbofan than in a turbojet so you can dump more fuel and get more extra thrust in a turbofan.

    In this drone there is no afterburner so there is cold bypass air and hot air that has been through the hot section and a flat nozzle forces the two airflows to mix more rapidly.

    If you look at how the piping is routed, it takes air from the latter stages of the compressor and pumps them to the nozzle creating a boundary layer of cooler air around the exhaust.

    In a normal bypass turbofan the air round the outside is the cold air while the centreline airflow is hot which would stop the engine nozzle getting too hot.

    By channelling high pressure but cold bypass air directly into specific points inside the flat nozzle it might be intended to ensure the entire inner surface of the flat nozzle has a layer of cold air between it and the hot section air so the flat nozzle does not overheat.

    The flat shape of the nozzle would mean the cold air and the hot air will be mixing as it moves through so the engine exhaust would appear cooler than from a round nozzle where the heat from the core airflow would radiate heat, while with this design the hot and cold air would already have mixed leading to not a super hot and a cold air stream but instead a hot stream of mixed air.

    Make no mistake the air would be hot anyway so standing in front of it, your clothes would likely burst into flames and be stripped from your body.
