OKB Korchagin KOR-70, proposed Yak-38 alternative

[flateric]

Initiative design of Korchagin's OKB, multi-purpose 'sea working horse' VTOL, born as branch of Korchagin-Beriev (Bartini) VVA-14 cooperative work, was proposed as smart alternative to Yak-38, supported by hi-rank naval aviation staff, but killed by MAP (Ministry of Aviation Industry).

some more

I've always thought it was very unique design. Nice pics.

On a tangent: I notice on image 3, "Space Ship One" is faintly visible. Were there good drawings of that in another article? I never have found good drawings of WK or SS1.

 

[flateric]

Not, to my sorrow. All I have seen is White Knight 3-view in Jane's 2005 ATWA and SS1 cutaway sideprofile (poor) in Scaled promo pdf files on their site.

Found that at rec.models.scale

Igor Shestakov (Unicraft) contacted Rutan (or whatever the company is
called) to ask about getting some official plans, and was ordered to
cease production and destroy all models. However, he argued that his
kit was produced only using photographs and drawings available to the
public, and, after removing the names 'Rutan', 'White Knight' and
'Spaceship One' (which WERE originally on the site), continues to
sell. Exactly what Rutan think of this, I can't say.

Hi Flateric

Very nice illustrations!...i always thought the Yak-38 was the only project subject to build the VTOL platform for russian Aircraft carriers.

I knew the Yak-36

Do you know if exist any other Russian VTOL projects?

It´s a very interesting topic

Saludos

[flateric]

Yes, I do, but this forum is not a place for well-known ones.
Please check your e-mail for more info, all little-known projects I will post here.

Non "unbuilt projects" discussion is welcome here:

Tupolev made a VTOL design to rival the Yakovlev ones (136).

 

[flateric]

While based on Bartini studies, Kor-70 was Berlin/Korchagin project.

I seem to be resurrecting a fair number of threads today.

You could say that the Korchagin KOR-70 was kind of a Soviet Type A V/STOL. Did any information on planned weapon loadouts, or mission payloads in general, ever come to light?

 

[royabulgaf]

Gregory, say hello to Igor for me, Kim Margosein. It would seem since this is a VTOL aircraft, would the planing surface of a floatplane be needed? Why not just use some sort of inflatable float? What about water ingestion as the exhaust would kick up enormous amounts of water. Nothing like ingesting a lot of salt water to get the overhaul time on the engines down to 30 minutes or so.

I would suspect that the floats were designed to not only help the KOR-70 in roles such as Search and Rescue, but also allow it to easily operate from bases and Forward Operating Locations that were established on major waterways, large bodies of water such as lakes and reservoirs, or in coastal areas. Also, when assigned to a ship, the floats would allow the aircraft a degree of independence from that ship, e.g. if the ship was lost and no other ship or base was in easy range, the crew wouldn't necessarily need to eject or ditch.

In a worse case scenario, the plane could act as a kind of lifeboat, at least for a time, but it would be more likely that the crew would be able to use the floats to stretch out their fuel, i.e. floating part of the way, flying part of the way to safety.

On another note, here's the Tupolev Object 136 that was mentioned earlier by overscan.

By the way, I've finally reached my 1000th post.

KOR-70 NEVER was Bartini project!!

 

[Stargazer]

Exactly. KOR-70 (or SVVP-70 as it also known) is a Korchagyn project.

 

[hesham]

Great work my dear Cy-27,


and for my dear Ucon,the SVVP-70 was a Bartini project,please see;

[Stargazer]

and for my dear Ucon,the SVVP-70 was a Bartini project,please see;

hesham, please do NOT tell ucon what is right and what is wrong!!!

You are only an enthusiast and he is a writer and a Bartini specialist. You are making a fool of yourself!!!

Stargazer,I am not fool,if you see the link,you will find it as a great Russian site,and they
mentioned that SVVP-70 was a Bartini design,not me.

How many times will we be having this discussion? When will you understand that the fact of reading something on a website doesn't necessarily make it true?! The web is full of false data and we need to be cautious with the information we share, especially if we present it as fact.

Now if someone who has access to the WHOLE Bartini and Korchagyn archives says that the KOR-70 was NEVER a Bartini project, I will trust that person more than an amateur's website! And this is exactly what is happening here.

Remember my own website on Burt Rutan? I spent months verifying every bit of information, and yet Burt Rutan himself was said to be annoyed at a few mistakes he found on the site. It is VERY difficult not to make mistakes, and unless you can go to the source documents there is always a risk! So please be humble about this and accept criticism for a change.

 

[hesham]

Stargazer,


that site is still working,you can ask its founder,about his source for that,and
here is anther mighty site,says the same thing.

When a mistake is created on the web, it spreads like a poison. Just go and see how many websites give "Thunderwarrior" as the name of the XF-103, even now that we know this was pure invention from an author! You could give me two, ten or a hundred links saying the same thing, that is not good enough.

that site is still working,you can ask its founder,about his source for that

Are you saying that it's ME who ought to go and verify the information YOU posted??? You have got some cheek!

 

[hesham]

I am not saying that,but we must verify the sources for those sites,and I am asking my dear
Ucon,what is the story of this aircraft ?,that's to know who really designed it.

 

[Jemiba]

Hesham, looking at those two sites, I can see, that on both the name Bartini is mentioned, but actually he
isn't stated to be the designer of the Kor.SVVP-70 at all. ! What's the problem ?
And, hesham, you have the statements of TWO proven experts with regards to Soviet/Russian aviation !

 

[hesham]

OK my dear Jemiba,


and I wait its story from them,but many other Russian sites,spoke about this
aircraft,as a Bartini design,so we will wait the explanation for this.

 

[Stargazer]

we will wait the explanation for this

There is NO explanation! It is a mistake, period! Bartini and Korchagin didn't work together at all, and for a very specific reason which I can't reveal here now (it will be in the book...). Some people have wrongly associated the KOR-70 with Bartini because it kind of resembled his designs. Don't forget that precise information was scarce before the breakup of the Soviet Union.

 

[flateric]

and I wait its story from them,but many other Russian sites,spoke about this

yes, Korchagin and other KOR-70 father, Berlin, were working at Bartini DB, but it was their initiative project and IT'S KNOWN AND PUBLISHED HERE SINCE 2001


damn, don't you see Kor.SVVP-70 VTOL floatplane by I.A.Berlin and V.A.Korchagin
more - it was Ucon and Zayarin, who have revealed KOR-70 story in details based on TANTK archives. are you seriously trying to question if they are right after reading tiny bits of info at some Swedish site?

 

[hesham]

OK my dear Flateric,


now I am convinced.
