US PATENT ON A FW190 EQUIPMENT ?

Hi all,

on a FW190A crash site we found this plate which - correct me if I am wrong - comes from a fuel pressure indicator.

What is amazing is that this plate shows a US Patent , it is indeed a Bendix equipment;

how is this possible this gauge could fitted on a German aircraft ?

Are you really sure, that you have a FW 190 crash site ?.

Re: US PATENT ON A FW190 EQUIPMENT ?

Hi Horst

99% sure we have a FW190.

We have a witness 97 year old who was there and explained us :

"a German single engine aircraft, with a round engine crashed there, it was in August 1943" and he indicated us the place at plaisance du Touch.

And this totally matches with Matti's data.

1943-08-05 JGr. Ost FW 190A-4 140673 Plaisance-du-Touch, 13 km westsüdwestlich Toulouse Notlandung infolge Motorstörung. Bruch 60 %.


In the field this old man indicated us, we found aircraft parts, including this plate. I understand that the fuel flow indicator was Bendix related on FW190, so it makes sense, but how explain that we had US Patent equipments on FW190 ?

Cheers

Gilles

PS : see post here above it is the same aircraft story

Gilles,
For me, it is unlikely this US plate comes from a FW 190, unless I am wrong...
or two planes on the same field (already seen).

Re: US PATENT ON A FW190 EQUIPMENT ?

It is possible there was another crash at this site, or the plate was dumped there. After the war, sometimes during, useful bits of metal were collected by local people. When clearing crashed Allied aircraft from a field, a part may be lost when larger pieces are collected. There may have been a post-war Allied aircraft crash there. A lot of possibilities to consider.

Re: US PATENT ON A FW190 EQUIPMENT ?

Well, thanks for your suggestions but the mystery remains;

It is a field where nothing else happened (no dump, no other crash in the area), the witness although old was very clear and precise, and his testimony matches perfectly with the archives;

Moreover, no US plane crashed around Toulouse (except a couple of B17 far away from this field).

So, just like the German planes were having "continental" tyres, I was wondering if they were not benefiting from US Patent inherited from the prewar period.

It would be good to have a FW190 instrument expert here.

Re: US PATENT ON A FW190 EQUIPMENT ?

On this crash site, I had found a part with a marking : 210-87-60 (see attachment)

which clearly was in favor of the FW190 hypothesis.

any comment on this marking ?

Re: US PATENT ON A FW190 EQUIPMENT ?

Bonjour Gilles

Autosyn instruments need an alternative current supply, typically 400 Hertz, and are very US specific, mainly on multi engine planes. From my limited knowledge, all the electric systems on the Fw 190 are operating on 24 Volt direct current, so the possibility of autosyn instruments on those planes seems remote. I will check if such kind of instruments where build under license in Germany, but, at least during the Fw 190 production period, it seems doubtful that they will exhibit a plate indicating a foreign origin.

I will also check if autosyn instruments can be found on the NAA 57.

Have a nice Sunday !

Bien amicalement

FYI,
Continental, est. 1871 is a german company then and still is based in Hannover.
