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.
