Re: Fw190 Spinner

Hi Peter,
From original VDM manual, the 9-12087.32 Haube is not listed. The closest numbered Haube is the 9-12087.34 for the Bf109G. However, It would seem much more likely that your number might be 9-12067.32? This number is correct for many variants of the Ju88, Ju188, and Do217 that had BMW801 engines. The Haube for the Fw190 A-B with BMW801C/D was the 9-12067.30.
From other sources, the Fw190D-9 is listed with the 9-21041.30 Haube. The Fw190D11/12/13 with 9-21036.34 Haube.
I dont have a reference at the moment for the Ta152 Haube. Cheers

SM

Re: Fw190 Spinner

Hi Schwarze-Man!
Thenx very much for reply. I bow my head to your knowledge.
Back to the topic. This spinners are from focke-wulf fighters
because were found in place when only made fw fighters,and was found with other fw190 parts. in this place was made version A and
probably other . about ta152 i know nothink. About numbers - on spinners they are places after plates. on a spinner and on a basis . close together. the number 9-12087.32-09-14 is
at the bottom of the base and could be different like on the spinnner .
Best regards Peter

Re: Fw190 Spinner

Hi Peter,
Yes, I agree, that number is definitely 9-12087.32-09.14 from what we can see.
This probably means that the particular component that is stamped with that number is a component that was designed originally for the 12087 Haube. However, it probably is being used in a different Haube as a component.
Unfortunately, I do not have all the drawings of all the Haube! It would be normal for the Haube to have two alloy makers id plates showing the Gerat Nr and the Werk Nr. These can be difficult to find but, would help. Cheers

Re: Fw190 Spinner

Hi Peter,
Now I can see! In your 3rd photograph that you just posted, the id plates are just to the right of the red square around the locking apparture. You can see their rectangular shape with a rivet at each end. Unfortunately, they look to be in poor condition. You might be able to get some numbers with a magnifying glass and possibly, putting oil on the surface? Good luck!

Re: Fw190 Spinner

Hi Peter,

The 3355.1 is the metal specification and, the symbol is the metal makers trademark. The slight "starry" ribbing of the diaphram is to add stiffness to it. The "bakelit" ring is a support ring that fits tightly onto the front of the propellor hub (Nabe) to hold the Haube steady and prevent it distorting in flight. That ring is described as gummi in the manual. It would be a hard rubber. Many other support rings like that are made in Tufnol, which is a reinforced resin. Cheers

Re: Fw190 Spinner

The measurements provided by miraul correspond to Fw 190 A/F/G spinners.

The prints specify 510 mm as a diameter, and 570 mm as a total vertical (without base plate and band.)

I cannot find the CD that has the ogive drawing and equation. I'm still looking for that set of CDs and will provide the drawings when I find them.

Interestingly enough, the ogive does not appear to be consistent as the series progressed. Ask schwarze-man, but I believe they were constantly fiddling with the airflow into the fan. And also, each prop version had its own spinner. This topic is actually quite complex.

Thank you, miraul, for a fascinating post.

Bronc

Hello SM,
All of this is absolutely correct.
Just a point: When you write "are made in Tufnol", are you saying "are" or "were"? In this instance other rings on Luftwaffe airplanes?
If so, another British product used by Germany during the WWII ?
Since it was and is British patented I'm quite surprised.
...
As for me I used Téflon(r) in Naval constructions and, later (more recently), German made cold mills for the same (generaly speaking) use.
...

For the curious, a very interested internet page:

Franck.
