Su-57 Stealth Fighter: News #8

That SU57 is definitely one of the prototype models built years ago.. It doesn't have smooth surfaces on its body. Which implies NO RAM.I can see the different metal welds on it.. Cant be a VVS example..

"52 Red" is an early production sample delivered during the latter part of 2021 for the VVS. It was on display at ARMY-2022.

I'm always impressed with those levcons.  The ingenuity and engineering is something I don't think has ever been done or seen before on any other aircraft, to my knowledge anyway.  

The wind-tunnel testing and incorporating the FBW system to automatically operate them optimally at all varying airspeed conditions must've been excruciatingly intensive.  They seem to be a better alternative to fixed LERXs since they don't operate as canards/foreplanes and certainly not as close-coupled canards.  You don't really see the excessive amounts of vortices coming off of them as you would with any of the other aircraft with huge LERXs like the F/A-18 Super Hornet.  They must contribute positively to the aircraft's drag coefficient.

It also looks like they've been strengthening their mechanism from initial prototypes to production.  They used to have only 2 hinges.



Now there's 7 like this one which is the same aircraft in your post.



And if anyone works on cars or is a mechanical engineer of some sort would know that it's not an easy "add-on" to make loool.  Particularly on something of this caliber that has to not only perform perfectly in every possible immense & extreme condition, but also last a lifetime.

Well according to one of the world's leading "military experts", David Ax from Business Insider, the Su-57 is a piece of crap. As a matter of fact, any military hardware from Russia is just crap. Must be hard for an expert like him to review all this useless Russian crap. I'm sure he would rather prefer to write about all the magical marvels at Disneyland.

Yeah, I go to the Business Insider for defence information like I go to Pedo Monthly for information on how to bring up children... which is not the same information as you would find in Cannibal Monthly, bringing up children is a completely different article.

They are in the same section at the newsagents I believe...

I wouldn't go to Business Insider for information on economics never mind geopolitics or the military industrial complex.

How about Forbes - any better?

Western sources can't be believed... I mean look at western rating agencies rating of the US and Russia in comparison... or for instance China... it is all just bullshit.

Looks like the su-75 cockpit

Beautiful. Full digital avionics is all fine and dandy, I suppose. I also think that old school technology shouldn't be completely dismissed, either. I think there's still a solid and necessary place for certain features in platforms as complex and advanced as today's modern fighter jets that still should be controlled with conventional switches. Touch screen is one thing, but having toggle switches for certain, particular features I think would still be much better, safer and easier to use. A balance in the ergonomics of design.

I know this is an old pic, but seeing one firing an R-74 is so damn rare I think it's worth posting.

Would make sense for them to be rather similar.

I thought the Su-57 cockpit had two side by side VDUs rather than one all your eggs in one basket VDU.

Nah, I think the new stuff is the continuous huge screen that acts like multiple screens all put together... well if you look at the cockpit display above it appears to be two wide screen monitors with the left one showing one "screen"... a tactical display showing targets defected by onboard sensors and probably from other platforms transmitted to the aircraft and the other wide screen on the right showing a split screen with the right showing ordinance and the state of the undercarriage and some engine information and on the left (the centre really), showing angle of attack and level and navigation and other instrument information...

It replicates two large screens placed side by side but is in actual fact one really big screen on which multiple smaller screens can be shown or if you want the whole display might show one thing... but obviously most of the time a few different things will be displayed.

The multifunction display buttons around the display are on the touch screen and can be changed by software to customise the display any way you like.

You of course have to keep in mind that the pilot will be wearing a helmet with an information field that displays information and images too and allows him to look at targets directing radar and IR sensors to display a better view of everything too.

They are doing the same thing for commanders in armoured vehicles and attack helicopters and flying drones too where onboard sensors display an external video view of the outside so with a helmet mounted display a tank commander can have the view from the top of his tank or a nearby drone, or the helicopter pilot can have a view from the nose of his helicopter for landing and flying with an unobstructed view of the ground.

The cockpit with the two screens side by side was the cockpit in the early Su-57 prototypes. It was exactly the same as in the Su-35:



The later Su-57 prototypes got the large screen display and wide angle HUD:

I've noticed other ways to tell the difference, too.  One is the contour of the HUD.  Su-57's seems to have a more circular shape compared to the squarish shape of the Su-35's.  The other which is much easier to notice (at least to me) is the outer shape of the fixed, forward canopy frame.  The Su-57's has a distinct, oval shape to the frame.  It's wider at the bottom connection to the body then wraps around in an oval pattern.  The Su-35's forward frame is quite circular all around instead of the oval shape.  It also flares out at the two bottom connections to the body which the 57's doesn't.  Two very distinct and noticeable shapes.  

I have a hunch that was the cruise missile that was off to the side of the x69 and other missiles. I remember everyone here was speculating on what that cruise missile was.

So, now the Su-57, like the Su-34, has a strategic-level weapon.

Found it and I wonder if this izd 720 is what they are referring to...

"Comparable range" would mean something between 3.000 and 5.000km.

The Gremlin, LRBM, plans of klevok-D2 over hermes, are basically the reasons I are assuming the 300km range will be on a R-77 design than a R-37 design.

Tactical aviation would obtain long-range cruise missiles.

It already has them. Currently only the Su-34 can launch long-range cruise missiles, but the Su-30 and Su-35 should be able to use them, too.
