Early Submersible Aircraft Projects

[Jemiba]

Apart from the post-war ones, some pre-war projects for such aircraft were already mentioned:

and not to forget the Ushakov and Harrington http://www.secretprojects.co.uk/forum/index.php/topic,703.msg5406.html#msg5406

The already mentioned article in the "Fliegerkalender 2014" shows two more projects, one designed by
Paul De Asis (US-patent 2.162.066) and the other from Earl Brigs (US-patent 2.444.332). Both should fold their
wings backwards for diving, but while the De Asis draing at least seem to have sufficient wing area, Briggs gave
his vehicle hardly more, than slightly enlarged depth rudders.

Nothing mentioned in this article and honestly I haven't heard or read about such projects in Germany
at all. Apart from the "Danish" project (http://www.secretprojects.co.uk/forum/index.php/topic,2504.msg199607.html#msg199607,
which probably was just a hoax, only he USA and to a much lesser intent, the Soviet Union seemed to have
been interested in this kind of vehicle.

The patent itself.
