Page of profiles of R-5 and R-Z of Tapani

[learstang]

Mr. Muchichko is a great craftsman.  The surface detail on the kits he mastered is always excellent.  I've always wondered if he did the master for the Amodel Ar-2, since the surface detail on that kit is amazing, the best I've ever seen in 1/72nd scale.  Every panel line, every rivet, is there.  I do wish someone would do his R-5's.

Great craftsman indeed. So, the ICM moulds are made with a master copied with apposite instruments, a traditional technology. No 3D computer modelling and CNC as Chinese firms do.
The Rieman commercial plane is the master built for Amodel, I suppose. So, he never built an R-10, I fear. I hoped that it would have opened the way to such a release.

Hi,
Another drawing.

IMHO, "transport" is not the word that describes the role of this aircraft the best.  Profile probably depicts plane that carried stretchers with wounded soldiers - "medical", "first aid", or something similar would be better.

Hi,
you could be right for this photo, on which the profile is based

that looks to bear a narrower version of these containers

while it transports newspaper on another photo
.
I'm in doubt for the star on the tail. Tapani didn't trace any star there asking me to complete the missing details; I added it, but now I'm starting to think that a smaller star on the rudder only would have been more appropriated, because the wire is  an obstacle to paint larger stars by mask.

Well, I've modified it.

Hi,
here are some variants of the '30s.

http://mig3.sovietwarplanes.com/r-5/tapani/executives.htm

There is an unclear thing:

Here it seems to write that only a plane, n.5215, was modified in this way, and that the wreck is its tail. But the division line between fin and rudder isn't the sane, and isn't of a typical R-5. Can the text make some clarity on this?
Regards
Massimo

I can read it says "TSAGI" on the tail, TsAGI being the Central Aerodynamic and Hydrodynamic Institute (which I'm sure you already know, Massimo), so this is probably just a one-off experimental version.  I'm sure someone who reads Russian better than me will be along to translate the text.

Hi Jason,
thank you for the suggestion.
It would be interesting to see if the text insists that it was the same plane or gives an explanation for the different tail shape.

Hi Jason,
that Russian text says that in 1932-34 specialists from TSAGI conducted tests how P-5 get out from spinner. And (as usually) shit happend on May 9, 1933...

Hi Massimo,
last week I guessed about the R-5 "Limuzin" number "20" and I missed...  
I checked Maslov's Armada and Kotelnikov's Aviakollektsiya issue and there is no references of that plane being "medevac"!
Only 5 R-5s were converted to carry 2 stretchers under wings in 1937 and that was it.  During the war, I guess (again...) U-2 was a primary medevac planes; U-2 could carry 2-3 wounded soldiers (1-2 stretchers depending on version).  R-5s were used as transports for larger loads (R-5 could lift between 500 and 1000kg) - R-5s supplied partisan units etc.

Back to R-5 "Limuzin" number "20":  both authors agree that it was a wartime modification.  It could be an one of a kind plane... I guess  .
Kotelnikov says that it was modified in Leningrad overhaul depot in 1941 (check http://lib.rus.ec/b/251378/read ).
There is a photo of this R-5 during overhaul in Armada on page 44.  This photo shows a small rudder red star without any outline.

More about wartime  R-5 "Limuzin" number "20":
Maslov calls this plane an "executive transport", Kotelnikov describes it as a "communication plane".  Maslov says that the same plane delivered newspapers in 1944 ( a lot of newspapers, between 500 and 1000kg).

Kotelnikov calls the streamlined underwing containers "kaseta Shcherbakova".  Sometimes it was called "Model 1934".  Two persons could fit in the container, but it was normally used as a cargo space for various loads.



Following is a airborne assault container ("desantnaya kabina") which was used to carry (and drop!!!) two soldiers-paratroopers.



Anyway, to reffer to the underwing containers as "passanger" is not appropriate in this case.  Also, experiments/record breaking attempts with 16 people in G-61 containers are not related to this plane.

HTH,

It's actually "liaison plane", not "communication plane"...

Hi Misos

Interesting, but does it say it was the same plane of the side photo?

excellent informations indeed, thank you very much!
About the star, the photo on which the profile is based is of 1944, I suppose that the outlines were added, anyway it is possible to make a variant of the profile. I should also  check the thickness and width od the containers.

No, it is not the same plane.
Rafaelyants Limuzin R-5 photo is related to page 12 text.

R-5 No 5215 was used in expeiments which were supposed to improve R-5's stall recovery charackteristics (Russian "shtopor" is translated as "stall").  This plane had movable rear wing struts - movable struts were supposed to function as rudder during stall recovery.
