Russian Su-57 Aircraft Thread (PAK-FA and IAF FGFA)

The climb aircraft appears to be the same aircraft that launches the side bay SRAAM because it has the same paint job. May not have been in the same sequence of events and the missile does appear to be "ejected" into a firing position at 1:19 if you slow it down to 0.25x speed. Then again it could have been in that position and was just hidden by the clouds before the moment it becomes visible but this is unlikely since we can see every other aspect of the plane clearly so what mysterious cloud hides just the missile which is right under the wing.

The sticking out position of the SRAAM is a curious sight though. The side bay mechanism is still shrouded in secrecy. I would sooner believe it's a drop away cover than some mechanism that extends the missile forward and holds it there but who knows.

Does anyone know what these bubble looking things in the canopy glass could be? Appears around 1:03. Maybe air bubbles in the canopy?

If you look in the lower right corner, there is also discoloration. Looks the same as the tinting film on car windows, so the air bubbles are probably just in between that layer. The glass itself is probably fine (would be a huge problem otherwise.)

It might be the same bird but not the same flight. The missile is also of interest here as it’s not compact enough to fit in the bay. Hence slide of hand.
Your bubbles are probably water droplets on the canopy.

The video is clearly a collage of footage from several flights & different airframes, I don't see how that would cast doubt on any of the individual segments, including the missile launch sequence though? Probably half the F-22 promo videos fall into the same category, and nobody ever voiced any skepticism over those.

How d'you figure the missile is too big?! Its position certainly doesn't match any of the known external pylons, the locations of which are conclusively established from photos and patent drawings.

Actually, it's pretty well known, the patent for the mechanism has been in the public domain for a number of years:

Yes, they're probably defects in the laminate, along with the discoloration noted by Mohsin77. You can also briefly see them at the beginning of the video where the canopy closes. At least one of the other early prototypes had a similar problem, it seems the final transparency configuration (including coatings and without visible heating elements in the windscreen) wasn't implemented until bort #510.

They're certainly not rain drops, not at that kind of speed!

First I am not saying that it didn’t fire a missile. I am disputing that the missile was internally mounted. That could mean that the door was removed or that the missile was mounted on an external hard point. As you agree with me we are watching not a continuous shot but series of shots edited together the slide of hand would be moving from the slick T50 to the armed one.
why do I say the missile is to big? The model of missile. The missile is and R74 that has a known width and length. CDB876B2-1F9E-4F80-AB59-1A47800617BB.png
the Russians months back the Russians showed off a new missile much more compacted. Deino tweeted about this than.

the New missile is on top in white orange, second is the R74 followed by the
R77. Because of the age of this image it’s doubtful that this new missile is ready for flight.
the outer bays for the SU57 are pod like structures built in the wing rout extension unlike the F22 where they are in the fuselage this limits the size of the missile fins and length. To fire the R73 the quick fix would be to remove the bay door and mount the missile hardware without as opposed to within.

Well, that's only half the story, right? As we have no concrete information on how large the bay is the precise dimensions of the missile provide no insight. It's merely a hunch that it wouldn't fit.

Make of this what you will, but the fin span of the AIM-9M missiles which the F-22 SRAAM bays were originally designed to hold is in fact quite a bit larger (almost 630mm):

The sticking point is the tail veins. The canoes like doors are fine at the front but shrink at the rear. The F22 and even J20 bays are more or less uniform from front to back. Su57’s are not. We know this because the side bays are visible under the wing. 0DBCDA51-558B-47C4-A412-3C473BECD380.jpeg
Just inboard of the slat but out of the intake that is the bay. That door dictates the size.

Nice edit. But it needs to be taken with a grain of salt.

The video is a montage of a number of videos with post production radio chatter. Because of the camera change and cut it can hide a bit of slide of hand. We see a T50 rocket into a zoom climb then cut. Then we see T50 with a missile clearly on the right side. It fires. That missile is supposed to be from the fighters intern side bay. Yet we don’t see the door. One shot is a clean fighter the next it has a missile.
not very much sure if it is launched from the inside bay,

there are smokes stains around right pylon...

and it just happened that the particular angle in the video blocks our sight...

Is there even a hard point near the side bay area? It looks very much like the missile was launched from the side bay from Deino's screen cap.

However, I am confused by how far the missile sticks out of the front of the bay. Is there a trapeze structure that juts it forward when deploying the missile?

Yep I mentioned it may be the same plane but not the same event - flight. Do you mean sleight of hand? Who knows if it's edited and how it works if not.

The bubbes are not water droplets. They do not move even as the plane accelerates about its axis - rolls.
