Su-57 Stealth Fighter: News #6

which comprises a small infrared imaging sensor to aid in low-level flying and landing; it is fitted in the forward section of the canoe shaped underwing missile bay.

You can certainly see that and the sensor looks a bit different than the drawing on the chart but that's ok.

 At least the whole thing is very noticeable.  But the rest of that weapons bay doesn't show any signs of doors that open up at all.  I was really hoping to see something definitive that would be convincing once and for all, but it yet eludes us again!  Do you see it still as a weapon's bay even now that you get a pretty good look at it and it doesn't have any seams that show where panels would open and close?  I really am trying to see it and be 100% convinced like you fellas.  Looks more like a cover or a cap of some sorts.

Mmm...so you're saying (and that bottom patent is also suggesting the same thing it seems) that the hinges are at the bottom of the V shape right at the point?  So only the outside half of the bay opens and swings downward at the bottom of the bay while the missile gets extended outward until it clears the bay and then gets fired?  That makes sense.  That's why I was looking for a gap of some kind at the bottom of that V shape where the hinges would be but couldn't see any.  Maybe it's just a super tight joint.

So the new Su-57 engine has a 50 year life span?

It definitely means they can be modernized a half-century from now, but if they can get a proper spin-detonation engine off the ground than that engine will definitely replace the current (and future second stage) Su-57 engines.

Russia is also working on the three stream engine, confirmed by Marchukov. We do not know how far they are in the development, but what they said leads to think they are at the stage of calculations. And also as you say, we do not know how good izd. 30 is, but we know it has the highest specific thrust globally and a low SFC, so how far they are behind US is very relative or even pure speculation.

The real news here is that they plan to start deliveries of 2nd stage engines already in 2022

PhSt wrote:This is probably a dumb question, but why are they calling the new engines (with serrated nozzles) 2nd stage? is there like a 3rd stage engine? are the 2nd stage engines only temporary? a stop gap?

As we keep on saying, Russia is seriously accelerating military development and procurement. I
