HISTORIE
GM-1/MW-50 system was considered, however,
the GM-1 system required a thermally insulated
tank unlike the MW-50. This idea was probably
abandoned due to technical complications. If the
Bf 109 was equipped with the MW-50 system,
the GM-1 installation of this third version was
impossible.
The GM-1 installation was nicknamed the ‘Ha-Ha
Prozess’, which is quite fitting given the effects
of nitrous oxide.
There are a quite a lot of inaccuracies, myths
and misconceptions on this topic in published
references. I will try to put the main ones in
perspective, which some may find contradictory
to what they have already read:
1. H.H.Vogt states in several places that the
installation of the GM-1 made it impossible to
mount the guns under the wings of the Bf 109.
However, this statement does not apply to the
G version, but only to the F-4/Z.
2. Robert Michulec (AJ
-
Press) reports that the
F-4/Z version had either pressure bottles or
a cylindrical tank for compressed nitrous oxide
in the wing. I believe that the cylindrical tank for
the GM-1 system was not present in the wing and
there was a visual confusion with this item and
the circular ammunition drum for the underwing
cannon.
3. Prien/Rodeike states, without any context, that
the Bf 109 G-5/U2's GM-1 pressure bottles were
located in the right wing, unlike the Bf 109 G-6/U2,
which had these installed in the fuselage. This
claim is not supported by any drawing or detailed
description and can therefore be considered
unproven. I find it highly unlikely that the GM-1
system compressed air bottles in the Bf 109 G-6
could be installed in the fuselage where the
nitrous oxide tank was already fitted because
the bottles simply wouldn’t fit.
