ONLY 3.6 mm !?

respect...

Beautiful craftsmanship!!! :-*

Thanks a lot.
It was purely a crazy fun project, while I was doing the F25. As the F55 is available from RS models, I thouhgt the microscopical F4,4 would be a cool addition to complete the Feuerlilie line-up.

I scaled Justo Mirandas drawing of the F25/I down to a 4,4cm diameter fuselage in 1:72 (->0,61mm) and did cut on that bases the parts from 0,1mm styrenesheet and a small piece of stretched sprue.
So I ended up getting possibly the smallest kit with 8 parts ever.

On the picture you see the tip of a scalpell as a size reference. I had to colourcode the parts not to mix them up.
And another shot of the finished miniature. I'm sorry that the image isn't sharper, but at this size that's the best my digital camera could provide.

I apologize, if I do "pollute" this thread a little with modelling stuff, which is not really the topic here.

Hi,


from the book; Bron Rakietowa w II Wojnie Swiatowej,here is the Rheinkinder
missiles.

 

[Grzesio]

The drawing is reproduced from a 1974 Polish book "Rakiety bojowe" (Combat rockets).
The left rocket is apparently based on the same original source as in the Kroulik/Ruzicka book, the right one was already presented in a 1960 book of the "Rakiety bojowe" authors' (this drawing: http://www.secretprojects.co.uk/forum/index.php?action=dlattach;topic=14170.0;attach=144689 ).

Awesome material guys!

Didn't knew the Hecht was built as well (just added it to the list of scale models to be build .

Btw; as we are right know with the Feuerlilie:
Does anyone has some additional info on the test model F4,4?
It's said that it was a scaled down F25 with a diameter 4,4cm to quicly test the general flight characteristics while the building of the F25 took longer than expected.
Was it really an exact replica of the F25 design or differed it in shape?
(I'm asking because the F25 and F55 do differ considerably as well)

Sadly, no data.
I think you just have to assume, 1st stage engine or/and subprojectiles are of the same size as in the closed warhead version.

I thought so, as the mainbody compared to the clusterrockets (if assumed they are the same, which should be inside the Rheinkind) seems exactly to be the engine part of the Rheinkind Entwurf with a simple cap put on top. Well, let's see, maybe I'm doing that version as well (if I manage to fiddle 12 of these Mini-Rheinkinder together in 1:72 ).

Well look what I have just found...
I must say respect to the modeller who had that courage...

So.... This Rheinkind rocket is basically a MRV SAM? Or better description is the Cluster Munitions SAM?

 

[Foo Fighter]

These are truly marvelous pieces of construction, nicely done, Sir.

 

[aazard]

Yes, that way the Rheinkinder make much more sense.

Possibly the T/K3/L3 is simply designating the fuels used in this version?

T for Tonka-250, a rocketfuel the germans invented during the war, named after the Tonkabean
K3 maybe for Kaliumnitrat (Kalisalpeter) KNO3
L3 well, here I'm lost. Usually you need sulferacid for the Kaliumnitrat to be what the German called "Salbei" (basically Salpetersäure).

Just an idea.

the Fuel of this Taifun is: Salbei aka S-Stoff (92 % HNO3 + 8 % H2SO4) and Tonka-250 (50% triethylamine and 50% xylidine,)
other Information give: SV-stoff and R-Stoff
T/K3/L3 is just designating this version of Taifun next to that were Taifun P (for Prototyp ) for prototype test an Taifun F (Finale version) as serie ? model

I believe "F" designation is the solid fuel, Ethylene glycol, variant called the "Wirbelsturm" (Tornado/or/Hurricane), due to T/S fuel type shortages (I will add a personal observation, t/s fuels, do not transport well, in same unit).

Note: This model was a "lower cost unit", under a british pound each, in era correct funds.. the main variant cost 2.60 UK pounds in era, each.

2 & 4/10 sec burn, I believe (if 3rd hand sources are semi accurate) the unit was slightly less powerful, with tests to 4200m altitudes, & glide to 8000m+ from launch site, 1250km/h speeds. Units exhausted in tests prior to r103 development

 

[aazard]

Rheinkind

Just saw this image, the F, "tornado", much of my "conjecture" is based off 3rd hand sources (some western, some soviet)

"F": I believe it is shorter, due to not having a dual tank, pump and its lack of a "full" firing chamber (being the "solid" variant), as a cost reduction (barrage fire) and due to various fuel shortages, swapping over to EG solid mix (similar to the reason additives were put in base components to liquid fuels, to prevent people drinking it as high test booze...extreme shortage)

Imagine a T/S fuel cascade reaction, at a anti-raid barrage site, with 1000's of units in storage (hypothetically). Its just not "safe", and more importantly, cost effective, to use such volatile fuels in mass

I have seen estimates, over the internet history of discussions on these units:
170 to 200 units expended, to score 1 downed "heavy" [b series] aircraft. Thats a 200 UK pound fee, to down a super fortress b29's $640K** USD (B29, each; Price: US$0.64 million, 1943)

**If the Torando's can be boosted to range by the Rheinkind carriers (service ceiling of B29 = 9710m)

Soviets created even three derivatives of the Taifun. KB-88 built R-103 and R-110, you mentioned, basing on the Taifun F, while KB-2 aka NII-642 created RZS-115 developed from the Taifun P. And Americans built their Loki.

Slightly off-topic but an excellent video about the Taifun:

[Pioneer]

I found the following
(I highlighted the interesting calculation)

Project of a German unguided anti-aircraft missile, respectively. similar to today's container ammunition.
The development took place in 1944 at the company Rheinmetall-Borsig. It was a 310 mm missile with a container warhead, in which were stored 12 pieces of arrow bullets caliber 45 mm, each weighing 4 kg. The missiles were to contain 0.7-1 kg of explosives and an impact lighter with self-destruction. After reaching a maximum speed of 1000 km/h, the ballistic hood was to fall off and the missiles were to fly without inertia propulsion further to the target. An empty rocket container with the engine was to be brought to the ground by parachute for further use. According to calculations, the effect should be 2-2.5 times higher than when using the rocket Taifun. With the mass use of this container rocket, its effects would be devastating.

Pioneer

According to calculations, the effect should be 2-2.5 times higher than when using the rocket Taifun.

This values apparently come from postwar Soviet calculations and refer to a variant with 18 sub-projectiles.

Interesting. Does a drawing of this soviet variant exist?

 

[Grzesio]

It was not a Soviet variant, just description of two German ones - with 18 projectiles located around the fuselage and with 12 projectiles inside the warhead. Both were already shown in this thread (e.g. post #44).
It has to be noted, the 1st variant is also described as having 8 or 12 projectiles in different books.
