Sukhoi T-75 LTS (CheckMate)

[Airborne2001]

Where do you get these fantasies about some kind of problems from everyone except you? The production of the Su-57 is progressing at a faster pace, accept it, you have lost

You know, I'm starting to realize that the perception of Russian aviation goes along the Churchill line of "Russia is never as strong as she appears; Russia is never as weak as she appears."

People dislike Russian aviation, then suddenly you join in that and the pendulum switches sides.

Plenty of people like Russian aviation, or at least take interest in the subject.

I don't make the rules...

One more patent from 2023 that wasn’t posted here.

Now usually they compare patents with Russian/Soviet ones, but I think this is the first time that they are actually comparing it to a western one, in this case F-35 style intake:

Great stuff .

Also i hope one day Sukhoi implement EORD-31 style OLS window on all of their aircraft, not with the purpose to meaningfully reduce RCS - but to stop endless OLS RCS discussions on forums all around the world

If Sukhoi understood the need to incorporate a faceted irst design, there wouldn't be any complaints on the internets...

There was a nice quote on that from Flateric a few pages ago.

I've gone back 7-8 pages & haven't found it, yet, although I never have been able to see what's under my own nose. Ugh. Sorry.

Sorry, it was in su-57 thread.

As my fellow aerospace engineer says, I often wonder why so much less advices from public how to do something are given on specific forums to neurosurgeons or nuclear reactor builders.

Sorry, it was in su-57 thread.

Ah yes. I've seen that one, lol.

It's high time to start relying on facts rather than fantasies in conversation. It is especially harmful to be guided by the lies of Western propaganda, just like any other. This approach will save you from severe disappointments in the future.

I can judge by the work of other organizations that I know of, where the 2026 plan is currently being implemented. In the case of the Su-57, this could mean + 12 aircraft. The reality is probably more modest, + 3 - 4 additional fighters

 

[Ainen]

Ah yes. I've seen that one, lol.

That's basically the point.
While I personally don't like presence of this ball on t-75 and consider it redundant(not like it matters for a paper plane, and not like mine opinion matters for aircraft design), as a matter of fact, sukhoi does now that faceting is.

And overall t-75 is facetted way more thoroughly than su-57.
Which leads to two simple conclusions:

(1)Yes, 75 RCS is probably low enough for it to make a difference.
(2)IRST ball carries functionality worth its placement and shape.

Why not adopt the same faceted approach in place of the irst bulb, though? Maybe The Su-75 then looks more like The Kaan from the front with such a modification, idk, but yeah - do that, keep the original V-Tail, & I honestly don't think that anyone would have a single complaint about such a design (as long as the irst/eots make use of iir technology), not that aircraft should ever be developed on such a rationale, of course, as our views don't matter, lol.

(1)IRST on Russian fighters after 3rd generation is a very important, WVR-optized tool, matching HOBS functionality. Sukhoi may be reluctant to remove it on manned aircraft.
In Su-57 it is significantly extended in use, both through data fusion and improved detection at range( obviously better processing of a later device; it's iirc a dual-band IR sensor).

(2)I speculated in 57/75 thread that DIRCM functionality may in fact be shared by 101KS-V. That would easily explain ball shape.
While known t-75 mock-up and models don't have other 101KS-O turrets, front IRST is likely shared.

(3) since we're speculating and whistling, I'd rather see F-35/J-20 like eodas solution in the nose as well, using Megapolis 101KS-U replacement (that huge optical window).
One less separate system for an aircraft said to be optimized for price, maintenance and ownership cost.
