wdym Yak 130M is a nice plane.

I agree. Though having a capability doesn't mean that they have it. You still have to integrate everything and make it work. As having a technology is only half way into integrating it and making it work. Though the Su 57M is the best fighter jet, no doubt about it in my books. There are alot of it's capabilities which are not being talked about despite of them actually being leaked and detailed in a few professional books and articles. Like it having radars all around it's fuselage and not just at the front of the plane. etc

What a great plane. 👍👍

Mate, China literally took Russian engines and planes. The WS 15 is a copy of an improved Russian Soloviev D30 engines. It's engines are good enough for the plane but not as good as 5th gen Russian or the US ones. The country that is leading right now in those high temp alloys is Russia. It can already achieve 1950 degrees. and is currently working on an up to 2200 degrees alloy. Nothing even comes close. There are only three 5th gen air dominance jet planes in the world, and China one is last in terms of it's capabilities ( but first in sheer production size). 1 Su57M - the best one. 2 F22A+ - was the best up until a few years back. 3 J20A - is the most produced one.

@hhtraveldocumentary wdym? It's not bad. Though I still haven't found a single concise and complete video on it, as I could literally do a much better job with so much information that I have on it, but I couldn't be bothered as it would take too much time, so I keep watching videos about it, and correcting some infos and refuting some myths as we go in the comments... But this video was more so on the point. Compare to any other Su57 videos out there.

@vp6087 before 1991 it was all Russia.

It doesn't resemble a YF23 at all. Completely different design.

@ikman4006 Those were bot comments literally just saw a guy repeating the same message with different words 5 times. of it "not being seen in combat"

@JohnDorian-j7x so they've modeled it without having access to the Su57? Genius... By the way you do realize that RCS depends on an angle and intensity and type of a signal that you're trying to get back , right? So your RCS will be different at different distances, different angles, and different types. You do know that right? ... We just have to trust them, that they'd used some kind of generalized comparable test... Sp the 0.1 to 1 RCS is a range for the whole Su57 aircraft. And it's very small, the smallest compared to the Su27/30s, or F15, 16, 18... Oh and the given RCS number for the F22 is again purely made up. People online made that number up (by the way it's officiall RCS is classified , so you wouldn't be able to confirm it anyway lol, and thats why they've made that number up , because there's no one who can disprove it, until they declassify the plane specs). It's actual RCS has been confirmed a couple of times by the Russian engineers at around 0.4 meters. Which is the same value that they were aiming for for the Su57. All of this talk doesn't really matter, because you can't check neither. And even if I said it has 0. 000001 RCS you wouldn't be able to check it, until you actually use a radar and check it. We know that it's obviously stealthier than the previous gen aircrafts, but how much stealthier, is debatable ( although we do know that it's not invisible, and if you fly close enough you will still see it on your radar... how close again is all relative and depending on several factors). So the only true factor of it's effectiveness can only be measured in combat. And there is only the Su 57 which is being used in an SMO, which has proven it's worth. Unlike with the J20 and F22. They've yet to prove their effectiveness.

Thats what they want it to be... but it's not a good plane so I dont see how they would be able to sell it to anyone.
4
J11 is Su27 though. And Su30 is based on Su27. So it's true.
4
@1ycan-eu9ji "D 30F6" is the one that they had used. Don't forget that J20 is a Russian MiG 144 project. The Russian MiG design bureau, went for a "paid vacation to China". So they obviously had used MiG engines. Like the ones on the MiG 31. It has a thrust of 150 kN
3
@JohnDorian-j7x ehh... how do you know that it's last? there's literally no proof. I know that they'd used special coatings (both in paint in it's canopy glass), special engines designed with stealth and it's ducts, angled stealth design, radio transmitters with stealth modes, munition inside it's fuselage etc. It was designed as a stealth aircraft from the ground up. And we know that it hasn't been shot down despite being used extensively in an SMO ( every other plane has been shut down), unlike the other 2 stealth planes. So from that fact alone would make it FIRST.

@Splattle101 i know about racism in the US that's not news to me. Just watch WW2 cartoons, you will know exactly what I'm talking about. I was talking specifically about the quality of their products.

It is not a 4.5+ gen it is the 4th gen. Russia doesn't have the best ones. Because all of it is a copy of the Russian jet fighters. Which are superior to the Chinese. The Su35SM is the best version of any of the other Russian or Chinese derives of the Su 27.
2
@voidtempering8700 Apparently I know more than the majority of the so called experts. The Su27 derivatives are: 7 Russian: Su27 Su30 Su32 (2 prototypes) Su33 Su34 Su35 Su37 (2 prototypes) 3 Chinese: J11 J15 J16
2
@voidtempering8700 1) Radars got nothing to do with the aircraft itself. 2) Russia was the first and the best to introduce PESA radars, AESA radars and such are it's modern derivatives and Russia has the most advanced ones for their fighter aircrafts. 3) All of the modern Su planes have EW. 4) "Sensor fusion" is just a technical jargon mambo jumbo that doesn't mean much. Su aircrafts had an integrated "sensor fusion" and full on fly by wire since the first Su30 ( and partial on Su27). As without it it wouldn't be able to fly or operate.
2
I think you got it wrong. Literally every 5th gen get plane gor a different design ( the ones that will hit production).
2
@kellysmith1144 It has completely different everything. Horizontal nozzle thrust, it's engine is not sticking out, it's "on top" of the fuselage, has no vectoring thrust ( for the reason described above), It is wider. It's tails are Su 75 like and not Su57 like . Diamond shape instead of an arrow shape, flattened canopy etc etc etc. It's literally everything is different about it.
2
@FallenPhoenix86 based on everything we know about it. They will try to bribe countries into buying it, but I doubt even with bribes anyone would dare to buy it... So probably a small series for it's own PLA airforce ( if that) and then everyone will forget about it.
1
@shoshe-jd4gf Check it's stats vs the J31. Also check how many planes were built. The F22 was made solely for the US and it's prohibited selling it abroad you even need authorization of approval to use it in combat ( it hasn't seen much combat because of that, that it's too good of a plane). The J31 was created for the mass market... And nobody wants to buy it. Because it's just simply. Not a good plane.
1
@marvinfok65 should be would be could be. It's not as of yet. Only hypothetically.
1
@kesai119 it is not just media nonsense. In fact I read very little from the media about this plane. It is more with my personal evaluation and knowledge on how things work. My own analysis. Which tells me that it won't be a good plane. Though they might still sell it if they manage to lobby it in other countries. Sometimes you don't need a good plane. If you control that particular country's political system, then you can just force them to buy it regardless...
1
It's much simpler than that. J31 is an attempted recreation of a Mig31 role. With western technology advancements. It turned out to just be a worse Mig31. Hence why they don't really know what to do with it now, as it's an OK plane with a specific role, and no one really wants an OK plane with a specific role unless it's cheap... really cheap...
1
It's a shame really that SR 10 never took off. It's whole point was that it was incredibly cheap (the cheapest training jet plane). It's plane price was to be around 1 million dollars, and it's flight hour cost at around 2k dollars which is incredibly cheap if you compare it to literally anything else... I don't think you can find a cheaper flight training jet plane, and it was unique and cool looking too.
1
@cerealport2726 ...? are you sure about that? I know their dentistry was pretty famous during these days, of incredible quality. As well as their planes. What products of bad quality are you speaking of?
1
The Su 57M is the best jet fighter ever created. And will be for a long time. Until the NGAD is released (if ever).
1
@viswajitbala7924 It's in series production.
1
@voidtempering8700 1) The radar is just one of the systems on the aircraft. And all of the modern crafts have them, just different versions of it. It's got nothing to do with the craft itself. 2) AESA - ACTIVE Electronically Scanned Array. PESA - PASSIVE Electronically Scanned Array. The difference is that it's active, and therefore more complex. But it uses the same principles. It is electronically scanned with many different sections on the radar of which it later electronically evaluates and complies the information "sensor fusion" mambo jumbo into one. Russia was the first to introduce PESA , and it still has the best radars. 3) EW is a very deep and complex topic. So you need to specify what you mean exactly by EW. As it has both internal and external EW. As there are different levels of EW it all literally depends on what someone actually means by it. Russia has the most advanced EW both internal and external (advanced) on all of it's aircrafts. 4) So then explain it? And you will come up to the same conclusion that I gave in my first reply.

Except that you are not really required to do that. You can just build a worse plane. Even if your design would be inefficient. As long as it doesn't immediately break or cause instability...
1
To answer the last part of your message - it was pure greed. It's way too common to make your systems with double redundancy in planes. I know that Russian do quadriple redundancy cabling and at least double with control systems on their military crafts. So it's a known thing in the aviation industry... Especially with modern day digital equipment which is prone to failure... so it was just pure greed from them... Because you not only save on installing the system, you also save a little bit on your cost per flight... pure greed.
1
@JohnDorian-j7x That's not what I was assuming at all. My other comment got deleted I think. But there's nothing that resembles it. Completely different design.
1
you mean YF23? not really. It's a unique design. Not related to the YF23 at all.
1
Most likely a real person. But you can't be too sure these days.
