Multi-Wing proposal(?) for the US Army

[boxkite]

In the German edition „Die ungewöhnlichsten Flugzeuge der Welt“ of the English original „The World’s Strangest Aircraft“ a table with different STOL – VTOL research aircraft layouts (from the 1950s) was published. An example is given to each category (for instance Bell X-14 for deflected jet, McDonnel XV-1 for unloaded rotor, Bell XV-3 for tilting rotor, etc.). Only one of the impressions, the multi-wing, is a mystery for me. Because all of the other sketches have a real background, I assume there was one (?) proposal for such a multi-wing STOL aircraft. In the scan is shown only a part of the table to give an impression of one of the other sketches (the tilting rotor XV-3).

Does anybody know more if actually a multi-wing was designed on the drawing board?

Could it be the Goodyear "Convo"? It's only speculation due to the description as a flying shade/(roller) blind ... I'm looking for details on this Goodyear design.

Also it might have been an Army proposal that was not taken on by any of the contractors, and thus just a consideration that the Army might have considered worth looking at.

Yes, the Beechcraft PD-159-1-1 Cascade, a likely contender of the Goodyear aircraft shown above.
