Arado Ar 234 P-5 Radar Equipment
« on: March 13, 2017, 12:21:53 pm »
Hello

I have a question regarding radar placement and variety on the P-5 version of the Arado Ar 234. Some sources state that FuG 240 Berlin would be used in the nose dome, while others say FuG 244 Bremen would be used in a rotating dish above the fuselage.

Questions: what is the difference other than placement between those systems (which is better), what is the more likely placement and could the two be used simultaneously on a same plane?

All answers are appreciated.

Kind regards, Stuka.

What I found via a quick search is a description intended for modellers, but with some sources given and
from what I could check still yet, it seems to be quite ok.

https://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd=9&cad=rja&uact=8&ved=0ahUKEwjXyO-359_SAhUHCBoKHZruDSsQFgg-MAg&url=http%3A%2F%2Fwww.modellbau-lippstadt.de%2F05_galerien%2Fmanfred%2Fbauberichte%2Fbaubericht%2520arado%2520ar%2520234%2520p-5%2520panoramageraet.pdf&usg=AFQjCNESurx-LGeYdUtwu6aA1cdASImayw&sig2=GAU55ru79l3QgVLlEH8xmQ&bvm=bv.149760088,bs.1,d.bGg

It says, that during 1944 research was done by the "Er probungstelle Werneuchen" for low drag radar installations.
The much smaller antennas for the centimetric radars could be used for cleaner installations, than before.
Nose, ventral and dorasl installations on the Ar 234 were tested in a wind tunnel, the latter two should give a panorama
view to track aerial targets, shadowing the bomber stream up to distances of 45 km. That radar set (FuG 240 Berlin N1a)
should be installed into a Ar 234 C-3.
The P-5 is mentioned as a night fighter with a FuG 244 Bremen 0 in a nose installation and a FuG 350 Naxos (passive
receiver).
There's no mention of a variant carrying both, the nose and the dorsal sets, although such a model is shown ...
To my opinion, a nose mounted radar would have been needed for a standard nightfighter, the dorsally mounted variant
for shadowing, both roles are hardly interchangeable. The aircraft would have needed both sets, workload for the radar
operator would have doubled, energy needs, too.

Mentioned sources are:
Geheimprojekt der Luftwaffe : Band 3
Die deutsche Luftrüstung Band 1-4
Gebhard Aders: Geschichte der deutschen Nachtjagd 1917-1945, 1. Auflage 1977, S.271
It takes a long time, before all mistakes are made ...
