Gordon,
Which Yahoo group are you thinking about?

Aubrey


Aubrey,

I just started a group specifically for ducted fans in hoembuilts:

http://groups.yahoo.com/group/ductedfanaircraft/members?o=6

So far there are only three members, Perry Mick, Donald Garrett and
myself. So come on over and get in on the ground floor..

There is another Yahoo group that's been around much longer called
ductfan, but its focus is wider and includes water propulsion, RC
aircraft, etc. Marc de Piolenc and George Wright are on there (they're
the authors of the book "Ducted Fan Design." That group has about 400
members.

http://groups.yahoo.com/group/ductfan/

I'm going to try to get everyone interested in homebuilt aircraft from
that group to join us on ductedfanaircraft.

I'm also putting up as much good technical info, pictures and graphics
as I can find into the files and pictures section. For example there is
a great paper from 1960 by August Raspet on designing a ducted fan STOL
aircraft. You can also find the first couple of chapters of the de
Piloenc-Wright book there, with kind permission of Marc and George.

Btw, I ordered George and Marc's book and just based on the first couple
of chapters I think it's a must read for anyone interested in this
subject. I have link on the group homepage for ordering.

Eventually the site will have all the information I can pull together on
ducted fan aircraft.

Regards,

Gordon.
