Neat that this is based on a flying model, not just fantasy, but I am very unclear on what the rotation of the circular wing would actually accomplish. Am I missing something?

 

[hesham]

My dear Cluttonfred,


do you mean it was a real design ?.

 

[cluttonfred]

Not a real design, no, but at least a serious concept that seems to have been based on experimental data. I just don't see the advantage to the rotating wing vs. a similar fixed wing.

Looking at the model, it is hard to tell which way the propeller rotates, but I would hazard a guess that the jets of gas from the rotating wing nozzles help counteract the propeller torque. The designer may have been misled into thinking that this would significantly improve a full-size craft.

But I do love the Captain Nemo style graphics.

The wing was to be filled with gas or hot air, so that aircvraft would have been kind of
a hybrid. On the disk wing of the model, four scoops can be seen. Maybe they would have
acted as kind of propellor blades, I think. Otherwise, I can see no advantage of such a
rotating disk, too.

Sorry, I don't mean jets of gas so much as the turbulent wakes interacting asymmetrically with the main airflow.

... the jets of gas from the rotating wing nozzles help counteract the propeller torque.

The article says, the wing disk is driven by a petrol engines, as is the prop.

Did anybody here tried to throw a Freesbee without letting it turn? I guess, he took the inspiration from a Freesbee or something similar. Have to admit I'm myself not totally clear, if the rotation of the Feesbee is simply for stabilisation, of if it produces more lift on one half (Flettner effect) than disturbance on the other half.

I wonder if the artwork inspired Matt Jeffries

The Pop Mech article was published in September 1930. Per Wikipedia, see https://en.wikipedia.org/wiki/Frisbee, the Frisbee was invented in the late 1930s, with the initial inspiration occurring at a Thanksgiving Day dinner in 1937, so we can safely rule out commercial Frisbees as the inspiration of this particular design. But as for other original sources, all bets are off.

That thing is just a poorly designed Chinook

Sure, but the effekt might have very well known before
