viewing book " Gli idrovolanti della seconda guerra mondiale " of Augusto Nani, Albertelli Editore ( that manage Tuttostoria ), i have seen that original project was a great flyinboat enginered by 4 Diesel Junkers 223 with 2500 hp (for engine), so in projected versions of production the airplanes coud be enginered by 4 BMW 801 !

Hi Gary,

Any chance of scanning these drawings to a larger size..??

Be nice if they were around three times the size so that the details are clearer.

Just a thought.

Grateful to see them anyway.

I have these scans at about 10 times larger files sizes. Way to big for this site.

I can burn you a disk if you give me your address.

Here is the last drawing. Though poor quality, it does show the land version BV 250 and how cargo was to be loaded. Note how the front landing gear is dropped to lower the nose.

Interestingly the Drawing is labeled P.161.01 not BV 250. Was this a different project from the BV 250?

Hi Gary,

each company had it`s designation system to allocate, e.g. numbers to their projects ( Junkers EF..., Arado E..., while most manufacturers chose the P... system, excluding Fw, a quite complicated one ). Blohm&Voss used the P... I consulted my literature ( Smith&Kay and Nowarra) and they all concur in giving the B&V P. 161 to the land based version of the Bv238. That`s the case. One more thing: P.161.01 means that it is the first design drawing on that particular project.

While surfing the microfilm at NASM archives, I chanced upon an absolutely crappy quality image of the BV 250 Zwilling. IMHO, one of the most outrageous designs ever proposed. The landing gear track appears to be over 40 meters. I could understand the BV tubular spar might be quite strong in some planes, but as the horizontal tail surfaces were not joined, it would seem that transferring torsion loads through the wing would have been a major structural design challege. IIRC, I have seen some sketches of this project before and felt it was another third reich fantasy. However, this appeared to be an authentic B&V drawing with the following information in the title block: P 167.01-01, BV 250-Zwilling. The date was too fuzzy to read. I will attempt to clean up the drawing and if that is successful, post it here.

Best Regards,

Artie Bob

In a rather serious fit of dyslexia, this topic had "BV 283" instead of BV 238 all over... I have fixed the problem now, but can only encourage each and every contributor to re-read their posts before clicking on the "Post" button...
