Re: Published Accounts of the Fw 200 C-3 – A Critique on Water-Methanol Injection

Part 5 of 5 – Now you see it and now you don’t, part two. For a last interesting comparison, here also are the supporting quotes from Kay+Smith’s Putnam German Aircraft of the Second World War on other aircraft designs fitted with the Bramo 323 R-2 – again for easy reference.

The key points of note here are two:
Even though there is no mention of water-methanol injection in the account for the Fw 200 C-3 in Kay+Smith, there is such a reference in the account here for the Ju 352,
and
although in this work (in direct contrast to Green’s Warplanes) the Ju 352 A is supposedly fitted with water-methanol injection, now the Ar 232 B is NOT fitted with water-methanol injection. That becomes the third contradiction in Kay+Smith of the equivalent statement in Green.

Clearly this is a point that has had authors at sixes and sevens for quite a while now.

Part A: Our Bramo 323 R-2s ARE fitted with water-methanol injection
Ju 352 A
“This aircraft [the Ju 353 V1] and the Ju 352 V2 were each powered by three 1,000 hp Bramo 323 R-2 air-cooled radials which could be boosted to 1,200 hp by water-methanol injection”
Kay+Smith’s Putnam German Aircraft of the Second World War, p.221-I
The only mention here of the main production subtype, the Do 24 T-3, is limited to the sale of the twelve examples to Spain in 1944.

Part B: But our Bramo 323 R-2s ARE NOT fitted with water-methanol injection
Do 24 T
“Both T-1s and T-2s were produced, with differences in internal equipment, and both used the 1,000 hp BMW-Bramo 323 R-2 radial engine (later redesignated BMW 301R).”
Kay+Smith’s Putnam German Aircraft of the Second World War, p.70-III
I can find no evidence in support of this claimed later engine designation.

Arado 232 B
“Eventually it was decided to replace the two BMW 801s with four 1,200 hp BMW-Bramo 323 R-2 radials, but this decision came too late to influence the first two prototypes, the Ar 232 V3 being the first to have the BMW 323 engines.”
Kay+Smith’s Putnam German Aircraft of the Second World War, p.29-III
However, note that the stated power output is that of the allegedly water-methanol boosted engine.

[Finally and incidentally, an ex-RAF flight engineer flying in Handley Page Hastings and Sunderlands in the 1950s told me that even then no such engine management device was fitted in any RAF four-engine plane that he ever crewed or knew of. Also, his immediate comment was that had this been the case, it would most probably have done him out of a job.]
