Sukhoi FSW Fighters from S-22 / S-32 to S-37 / Su-47 Berkut

[F-2]

That’s an amazing pic! You can really see the naval lineage.

Anyway apparently the radar for the Su-27km would have been the never built RLPK-32 radar. I don’t know enough about Soviet/Russian radar designations to know if that name has any useful information, source does not elaborate.

Sukhoi S-22 – a blast from the past

A BOOK published recently to mark the 80th anniversary of the...

RLPK just means "radar" and -32 is for the S-32 designation. RPLK-29 is one of the designations of the N019 "Rubin" radars on the MIG-29 and RPLK-27 for the Su-27 with N001 "Myech". It doesn't help identify the intended radar.

No but the name and the fact it’s described as being canceled is interesting if for no other reason it implies it would have its own radar rather then something completely off the self.

Had known that at already at an early stage the whole FSW Project of Sukhoi had always also an Navy version in mind and the S-32, and so on where shown in drawings and desktop models with tailhook. Also, a Navy-Version needs folding wings to save space on the aircraftcarrier. Often its said that the real build Su-47 has a tailhook. But I never had seen a photo of the Su-47 with a tailhook. and in the new Su-57 book from Yefim Gordon is nothing written about it. But from this book ilearnd that the Su-47 has manualy folding wing. The is als one photo. Does anyone know a photo showing the Su-47's tailhook (if it exists). Does anyone know a photo showing the Su-47 with folded wings from a different viewpoint (sideview,..) ?View attachment 672151

It's not a fact that the version is for the Navy. The photo shows the wings undocked and that's it. If the wings were folded, the flaps would look the other way.

they are folded

1 more. I believe this is the SLM-22 drop model of the S-22.

On August 12, 2021, on the eve of the Day of the Russian Air Fleet, a solemn event dedicated to the opening of the Alley of Heroes memorial complex was held at the Flight Research Institute.

The memorial complex of the Flight Research Institute is also the stand "Outstanding Aviation Figures", which displays portraits of scientists, aircraft designers, engineers who have made an invaluable contribution to the development of domestic aviation and the history of conquering the sky; and the legendary "Alley of Heroes", where the memory of the honored test pilots and Heroes of the USSR and the Russian Federation is immortalized.

In its anniversary year, the memorial complex experienced a rebirth, and it included a new composition - the stele "Dedicated to those whose mind gave people wings", presented in the form of a model of the Su-47 aircraft.

At the opening ceremony, the general director of the LII, Evgeny Yuryevich Pushkarsky, addressed the staff of the Institute with a welcoming speech. He noted that a lot has changed over the decades that have passed since the formation of the Flight Research Institute. Aviation equipment, the level of training of specialists, the technical equipment of the experimental base became different, but the main thing remained unchanged - the fundamental approach to research and testing: namely, objectivity, completeness and reliability in testing and researching new aviation equipment.

It is this approach that our pilots, scientists and engineers are implementing in their daily activities at FRI today, it is this approach that is the link between the past of the Institute, its present and its future.

Also, the scientific director of the Institute Tsyplakov Vladislav Vasilyevich and the guest of honor of the LII, deputy of the State Duma Denis Borisovich Kravchenko, addressed the audience. They congratulated those present on the occasion and the 80th anniversary of the Institute, noted the importance of the FRI in the development of domestic aviation.

After the opening of the Alley of Heroes memorial complex, a flower-laying ceremony was held at the monument to the first head of the Flight Research Institute, Mikhail Mikhailovich Gromov.

The memory of the past is our deeds in the present. The memorial complex of the Flight Research Institute is a clear example of the universal respect of all generations of FRI workers, a tribute to the founders of aviation who contributed to the development of the aviation industry in our country.

I'm pretty sure the s-22 and su-27km are "different" aircraft.

 

[Erdosain]

That's how it is. They are different projects.

They differ mainly in the air intakes and exhaust nozzles.

Some even confuse the S-32 with the Su-27KM, or say that the S-32 is the naval version of the S-22 later renamed Su-27KM.

S-22 is R-79 and associated intake?
S-32 is Al-41f and associated intake?
Su-27km is naval S-32?

 

[User323847]

it's scary to imagine what Russian prototypes have been created in 1982 and are being created, which we won't hear about for many more years.

1982 crazy, just don’t understand how Sukhoi..?

 

[overscan (PaulMM)]

Yes, that's the S-22 (note the "22" bort number in yelliow) mockup. We already have a topic for this:

Was the Su-47 stealthy ? I've already seen in a documentary that it was, but I'm a bit surprised.

It wasn’t like a stealth aircraft but it probably had provisions to limit RCS and significantly it had an internal weapons bay.

 

[paralay]

RCS Su-47, minimum 1.8 m2, maximum 9.8 m2 (estimation)
Radio-absorbing materials in the S-37 design.

[sommebodhy]

I've heard the Su-47 uses D-30F11 which is supposed to be the same engine powering the MiG-31?
It's hard for me to believe that knowing how massive MiG-31 engine was so if anyone can provide clarification that would be helpful

 

[paralay]

Probably so

 

[sommebodhy]

Probably so

What the hell
So it is very much possible if the Su-47 is a standard swept wing aircraft it could possibly be on par with the MiG-31 in terms of size and speed?

Izdeliye 70

Is there any difference between it and D-30F6 used by MiG-31 other than exhaust diameter?

 

[paralay]

So it is very much possible if the Su-47 is a standard swept wing aircraft it could possibly be on par with the MiG-31 in terms of size and speed?

Can not. The air intakes of the Su-47 are unregulated, that is, the speed is limited to M = 2.1. The sweep of the wing is 20 degrees, selected from the conditions of takeoff from the springboard and is clearly insufficient for supersonic even M = 2.35

It's interesting to see this tandem fan configuration (which I assume was used to achieve variable bypass). This seemed to have been a popular choice in late 80s Soviet experimental aviation, with the T-12 (Su-25 successor) sporting a similar arrangement.
Wonder what's the advantages and disadvantages compared to the more modern three-circuit engines (an obvious one is this is less compact), and why did it die out?

interesting solution. Curious about how the pilot is supposed to aim during a dogfight. Helmet mounted sight I guess?

Thanks, here from the member @QuadroFX the title of the publication, just in case somebody else wants to look it up in a library in Russia.

"85th Anniversary of Sukhoi design buro" - the one you're never going to get, like most of us )

This is TsAGI research model dubbed Ritm ('Rhytm')
What are your sources for 'another S-22' - while we never seen 'normal S-22' yet?

So Rhytm _was_ an early S-22 and not an in-house TsAGI study as I was insisting back then.

Similar solution with an early T10 (pre Su-27) design. Interesting SRAAM bay as well.

It's a good book, if you can get hold of a copy Its similar to the MiG Flying through time 2 volume book. Mostly production, with a nice sprinkling of projects.
