Sukhoi LTS "Checkmate" #2

I showed a picture of the LEVCON in full deflection - because of what you said. There is no other possible interpretation when you say "lowest angle setting" that "blocks the engine from in front".

So you are saying that the lowest angle setting which you posted a picture of with the aircraft on the ground, is not for use in flight, but is actually to hide the engine when the aircraft is sitting on the ground?

Do the horizontal tail surfaces on an Su-27 actually go to vertical to provide shade to people standing behind them in the early morning when the sun comes up?

Or do they both deflect as far as they need to deflect for aerodynamic reasons or other reasons?

Don't know myself... just asking an expert who is never wrong.

The LEVCON is purely an aerodynamic aid during flight - in short it is a moveable LERX.

So it deflects that far because it is also an airbrake?

But you did...

You seem to have attached your own ideas to what I said.

If I meant to say the engine exhaust blew over these control surfaces and increased their effect that is what I would have said... why would there need to be any mention of a wind tunnel effect if the engine exhaust blew directly over the surfaces?

TLDR, Sukhoi doesn't know how to build planes, only MiG does. But they are more corrupt and ruthless and that's why VKS keep buying only Sukhois.

Yeah, you didn't read something and make a comment anyway. Not reading but still commenting... but your fan boys still clap... it is pretty clear Mir is not reading either.

With all the cleansing going at the Russian MOD MiG is probably looking forward to the newly opened prospects in the second hand and scale model markets

The anti MiG circle jerk... losing any real respect here.

Sukhoi vapourware seems so much more expensive... have they transitioned to American design school techniques?

Shiny glossy adverts but no substance... their heavy 5th gen fighter is lighter than the Su-35 and their light 5th gen fighter is heavier than the MiG-35, but the MiG-35 is useless because it is too heavy and too close to the Su-35 to be different... just buy Su-35s.

By that logic the Su-75 will be worse.

Now where were we...?
Oh OK!

is that the working prototype LTS model?

No not yet. This is the static test machine that was used during the unveiling. Probably some PR shots before engine testing as both are fitted with the AL-51 engines.
I think the first flying prototype will have the new shape?

Man this thing just looks proper

As far as the LTS goes, considering the AL51 is even more fuel efficient than the predecessor, do you guys see them tweaking that engine for single engine use by sacrificing a bit of fuel efficiency for more power given the fact that there is only one engine sipping fuel?

Su-75 Checkmate Test Spotted Over Far East

If this is indeed the Su-75, it means that the fighter has already made its first flight and is undergoing testing. The Su-75 Checkmate is designed as a cheaper single-engine fighter to pair with the Su-57, similar to the MiG-29 and Su-27 combination of the 1980s.

Previously, there were no reports that the Su-75 had already taken to the air. UAC only showed a model of the aircraft at exhibitions. Since the first display in 2021, designers have managed to change the appearance of the Su-75, increasing the aircraft's lifting surface.

If true then I guess Xmas 2035 has arrived a bit earlier than expected!      

Seriously though I think 2025 is going to be a pivotal year for the Russian military (and Russia as a whole).
Can't say the same of 404. It's going to be a terrible year  

The first flight of the Checkmate will take place in 2024, Head of the Ministry of Industry and Trade Denis Manturov said in a [March 2023] interview with Interfax.

Russia has always reported such events officially.

Before the SMO.

Well on the VVS thread we were discussing a claim that they were going to reveal a new plane with new design for the first time... maybe they were talking about the Su-75 first flying prototype.

It was long range aviation, but the Su-75 is really the only brand new design of fundamental new design we know of... unless they meant the MiG single engined fighter.

The description of the new aircraft sounded rather similar to the description of what turned out to be the Su-75 at MAKS, so I would not be shocked if that is what they were talking about... translation issues can be confusing.

It could be time to reveal the PAK-DA, or less likely PAK-DP, but it would be uncharacteristically Russian... on the other hand they seem to have taken very seriously the fair at Zhuhai, bringing a lot of new products there.

BTW, the claim is that the pictures above are of a RC model

If true then I guess Xmas 2035 has arrived a bit earlier than expected!

First of all estimates are estimates and are never intended to be perfect... just an indication.

Second a blurry photo of a shape in the sky means nothing... there is nothing in the image to offer scale... it might just be a scale test model to confirm the different aerodynamic changes they have been making. It could be a model some guy or girl made for fun.

Can't say the same of 404. It's going to be a terrible year

The last ten years have been shit years for the Ukraine, but they are an independent democracy that has to fight to the last man because the US says so. They picked their allies and friends and pissed all over their large neighbour and now they are harvesting their bitter crop.... ironically it might damage their soil... there is such a thing as too much blood and bone additives to soils and of course AIDS and Hepatitis C are not the best ingredients either... and the levels of some drugs will be near toxic levels too.

BTW, the claim is that the pictures above are of a RC model

Which is ironic because the beat up damaged Su-57 on display at that airshow that everyone is complaining about is a non flying model because they didn't want the public to get close access with high res cameras and other equipment...

If you read my sentence again you will see that it started with "If true", meaning that I am not entirely convinced by the picture. However there has been an official statement that the first flying prototype is expected to get into the air near the end of 2024, which makes the 2035 estimation looking even more ridiculous than it is!

hope this is a joke but they are presenting 5m2 at 160kms for the radar. https://x.com/MuxelAero/status/1856654006044537174 I am assuming this is just an export version if it had
Bars radar

It is for export... I am sure if a customer country wants to spend a little extra and make a better radar for the aircraft that the Russian companies would accommodate them, but as a base model that would be OK to start with.

This aircraft will not be on its own and will be operating with other aircraft including Su-57s and MiG-31s in a Russian military... and also with ground based air defence forces which will also be sharing information.

The history of the creation and development of the T-75 light tactical fighter (Su-75, The Checkmate) has been published.

https://x.com/snekotron/status/1859338599898235105

What is noteworthy here is that the mission profile analogues cited aren't any current Russian or adversary multirole fighters. Instead the Su-75 is compared to the Su-17, Su-24, and MiG-27.

CGI artist added surplus engine

not sexually attracted to aircrafts or anything but they look amazing getting painted grey.

Important to carry a spare I guess....

Or is this a MiG prototype twin engined light fighter mockup CGI?

Do you seriously think that this is actually the Su-75!?
(or anything else for real)

Looks more like a CGI of one of the "MiG-41" versions.

Do you seriously think that this is actually the Su-75!? Laughing
(or anything else for real)

But if it isn't the Su-75 then why would it be posted in this thread?

Maybe it is the Chinese Su-75... their F-35 version has two engines, perhaps their version of the Su-75 will have two engines as well...
