Johnson Uni-Plane and Nemeth Parasol

[Stargazer]

In 1934, an American named Richard B. Johnson built and flew the Uni-Plane(or Uniplane in some sources), a most unusual aircraft with a circular wing, built around a Church Mid-wing fuselage and powered by a 41 hp Church Marathon engine. According to Aerofiles:

Uni-Plane apparently had trouble feeling at home in the air, and for two years made more than 100 short, stright-line flights, many of which ended in one form of crash or other. Offered to Chicago meat packer as a "flying ham" advertisement during the World's Fair, but rejected after it crashed on take-off in Aug 1934. In 1936, a final and spectacular crash slammed the lid on things, and Johnson traded what was left for his hangar rent.

Here is a series of drawings of the Uni-Plane taken from the Jan.-Mar. 1977 issue of Luftfahrt International:

• An early circular wing design which still used the Clark "Y" wing profile.
• The U.S. Patent that was directly derived from this design.
• A 5-view arrangement of the Uni-Plane, now using the "M-6" wing profile, and showing two successive tail fin configurations.
• Two photos of the Uni-Plane prototype [NX13680] from the collection of Bruce Bissonette (source: http://www.shu-aero.com).

I wonder ???? What happens when you install a split flap under the centre of lift on a parasol circular wing?
