I have some microfilm from the NASM archives that shows an unknown Blohm und Voss Project.

The drawings are labeled Ae M 41.

Can anyone shed some light on this project?

Hi Gary,

nice to know from you again. You might remember me, some years ago I sent you some copies of Kiryll von Gersdorff`s book on german helicopters. Welcome.

Wow! What a find! I am unable to read any of the dimensions, any chance of posting clearer or larger images?

Any idea what the engine is? The Cowling looks very long, as does the spinner suggesting a contra prop?

Nick,

I'll post a closer file with the dimensions more readable in a few days.

The associated document is virtually unreadable. The microfilm is out of focus and I can not make out anything readable.

Carlos, good to hear from you again.

Here is a cleaner version with measurements.

Documents are dated 1944.

Hi guys,

the spinner does sugest contrarotating propellers, but the estimated cowling measurements imply a radial engine with no more than two rows. It could be a 14 cylinder ( BMW 801/804/805 family ), a 18 cylinder ( BMW802 ) or the enigmatic Argus Ar403 radial , either P5 or P9 variants. Bye.

Hi Kiradog,


I saw something like that in NASA report from while,but to be honest,I don't find the name of
Blohm and Voss on it.

In the upper left corner of the drawings key you can see the Blohm & Voss logo,
so, assuming it's authentic, there's no question, I think.

Then, perhaps you should post those drawings, so we can discuss, if it actually is
the same aircraft ? ;)
As it's a design with variable geometry, it's understandable, that it was interesting for
NASA, so it may well have been pictured in other reports.

Sorry my dear Jemiba,


I saw a report in NASA site from long time ago,but unfortunately I didn't keep it,I think it was
just a hypothetical model.

News like this give sense to my life!
Two questions:
1- Is the "Ae" prefix related to any known company or designer? I don't remember, actually. :-\
2- Would be interesting to translate exactly the notes. I can guess that one reads "front suspension" (landing gear attachment point, maybe?) and the second could be related to the centre of gravity or pressure of the wing. Both have three slightly shifted position for three different wing layout (+ and - swept and straight). Hardly understandable how the sweepback wing's root would be attached to the front fuselage.

Thank you very much.

The draftsman obviously made an insertion/correction to the caption about the center of lift,
actually writing to sentences, using the beginning for both.
