U shaped wings

Some time ago there was a magazine cover showing a twin engine aircraft
with a U shape in each wing. The U's curved downward then up again with
engines and props within the U.
When did that occur and what magazine was that; anyone know? A vague memory
points to popular mechanics or popular science.

Custer Channel Wing.

I made an RC model of one years ago. The darn thing would fly so slow
the flight controls couldn't get a grip on the air. Losing an engine
when flying that slow was catastrophic, however.

I would think that an engine out on takeoff would be about 100% fatal. Such
a huge difference in lift would cause an immediate wing over and spin.

It's essentially a "blown wing" or "powered lift" aircraft. The only
way it would be even remotely safe is to link the props with a cross
shaft with Sprague clutches somewhat like the V-22 Osprey. That way
if one engine failed, both props continue to be powered. Even then it
could only be justified for special missions that needed the STOL
capability badly.

However, a single engine channel wing is possible.

That is what effectively killed the Custer Channelwing.

According to one of the pages on the custerchannelwing.com site, a German
company by the name of Rhein Flugseubau experimented with a single channel
wing variant called the RFV-1 in the 1960s:

Thanks Dan - Custer channel wing it was.

Not exactly a Channel Wing, but this plane is a fully ducted wing
