Check 1950s patents.  What you have sketched is the same thing
as the capsules used by the Navy to carry one man under the
Skyhook balloons.   Most of them were patented by the same
chap who did the design work on Alvin.  You may be able to
tease out of those patents some detail information that you
can use.

I'll try to look in my files.
