I want to do some round wings aircraft.
So far I have the MAI Avrocar, the Special Hobby Sack and the Mando
Models Discoplane.
Anybody know of others and 1/72 kits of them?
TIA
Tom
Thanks Pat.I had already added the Sword Vought V-173 and Pegasus
XF5U-1 for a total of five on hand.Now to seek out a Fine Molds
XF5U-1. Actually I need two, one for a friend.Happy modeling,TomOn Feb

The details in the Unicraft kit of the BMW Flugelrad I V1 state that
the single prototype was built in 1943 and made a maiden flight
between August and September of the same year from the Czech airfield
of Prag-Kbely.
Does anyone know if this actually took place? I want to do models of
round wing aircraft, but I'm sticking to those which reached at least
the prototype stage, not paper projects. Of the six that I have so far
only the XF5U-1 never flew.
TIA,
Tom
I don't know about models, but I have been collecting patents, NACA
papers, and anything else I can find on circular airplanes. If anyone
wants anything, ask. The best stuff seems to be from Zimmerman who
was responsible for the V-173.

In all likelihood the whole Flugelrad story is a complete fabrication;
as you go back in time, things about it become just a rumor, and over
the years more and more details are added to it, like the Loch Ness
monster and Bigfoot stories.
Supposedly, it was based on this technology:

completely forgot this wonder, which although there is no model of it
available, has to be seen to be believed, and did indeed get built, at
least as a subscale prototype. Behold René Couzinet's RC-360 Aerodyne
in all of its glory:

was to be lifted by rotor blades around its periphery, and driven
forward by a jet engine under its belly.
The rotors are spinning here:

as I might, I have never been able to figure out the principle this
thing was supposed to use to generate lift and control itself... it
appears there are two sets of rotors at two different levels on both the
top and bottom sections of the saucer, and that the top and bottom
probably counter-rotate to cancel out the gyroscopic effect.
Here's more on it, from the USAF Air Intelligence Digest in 1956:

project, in a warped form, could be responsible for the Flugelrad
story also, as the layout is very similar...besides which, Couzinet did
some work with the Germans in occupied France during WW II.

My interest in round winged aircraft was begun several years back when
I stumbled across one stored in the rafters of a garage/shed that was
once a hanger. All that was left was the wood and canvas "rotor" which
would have been attached to a DH.4. The lower wing was shortened, but
left in place, as were the tail unit, landing gear, engine and
cowling. The circular device was attached to a shaft between the
cockpits.
As the aircraft picked up speed the "rotor" began rotating, creating
lift. An autogyro, right? But wait. As the speed increased the
"rotor", which was cut into a spiral, expanded like a De Vinci
airscrew, giving tremendous lift. Cool, huh?
I have photos of the thing and copies of the patent. It never made it
as far as being attached to an aircraft as the arrival of slats and
flaps ended the need. The inventor, Marin County's first Sheriff, went
on to become the first county fish and game officer as well. He
patrolled from Stinson Beach where his hanger was/is. On one occasion
he exchanged gun fire with poachers in West Marin.
After this batch of round wings I may attempt Selmer's odd machine.
Cheers,
Tom

According to the ancient Doug Rolfe book, "Airplanes of the World",
there were a apparently number of fairly successful flying disks going
back to the pioneer era (pre-WWI) like the Kitchen
"Doughnut" (circular biplane wings with central circular cut outs),
Cedric Lee's Disk craft (monoplane), and the Miami University "Flying
Saucer" (parasol disk wing).
