Time to put you all out of your misery...

...it's the magnificently-named CAC Wackett

CAC Wackett - Wikipedia

Now we can concentrate on identifying Zach's cable-laying floatplane. If that's what it's doing. 🤔

I am in the homepage picture... or I would be if they hadn't cropped off the bottom part of it. 🍻

@ZachariasX  Plymouth A-A-2004 - rotating things have something to do with magnus effect.  Type that in a google search with "aircarft" added and its the first wikki thing you hit

The Aussies broke me. I couldn‘t make that.

100 points to the winner!

It is built around Anton Flettners patent covering a spinning tube/rod acting like a wing profile and its application in a wind turbine.

Today, we can actually calculate the efficiency of the idea, and it is a mixed bag at best, but not in a good way. There is an article on that design here, from which I quote some tidbits:

https://www.researchgate.net/profile/Uwe-Borchert-2/publication/324681135_Numerical_Investigation_of_a_Wind_Turbine_with_Flettner_Rotor_Rotating_on_and_Transversely_to_the_Main_Axis/links/5adbd8e5a6fdcc29358a346c/Numerical-Investigation-of-a-Wind-Turbine-with-Flettner-Rotor-Rotating-on-and-Transversely-to-the-Main-Axis.pdf?origin=publication_detail&_tp=eyJjb250ZXh0Ijp7ImZpcnN0UGFnZSI6InB1YmxpY2F0aW9uRG93bmxvYWQiLCJwYWdlIjoicHVibGljYXRpb25Eb3dubG9hZCIsInByZXZpb3VzUGFnZSI6Il9kaXJlY3QifX0

In that long link, we are explained the theory behind it:

and that on ships, such rod „sails“ actually worked, somehow. What looks like Stable Diffusion gone wild is actually a design:

As for this Plymouth „aircraft“, the idea was to let the wing tubes spin and when pulled forward, they behave like a traditional wing:

IIRC, they even said that this contrapition managed to fly. If they said so, well, sure Jen. I guess there is a reason why we only have a drawing of it in flight.

But it indeed produces lift:

It does so at a higher rotational speed and slower airflow, making it essentially a slow aircraft. Also it would require optimized boundary layer conditions. And, most of all, if the drums stop spinning, the wing ceases being a wing at all and the crate drops like a brick.

Thanks to Uwe Borchert for this further piece of useless knowledge.

Here we go then - closest thing to a Gerry Anderson design ever to appear in rL

That’s gotta be the *magnificent Martin P6M Seamaster.
 

*Magnificent as long as you didn’t have to fly the prototypes.

Vickers type 432?

I‘d say that as well.

The British made great performing aircraft, and some had even the looks for it. And once they had an example that excelled at both, any subsequent had to have the same look. Usually, they were unsatisfactory designs.

The nearest thing I can think of is the Heinkel He280... which it isn't.

I can tell you that this aint no one off prototype. This thing was a front liner

SAAB 21. Now it it the piston or jet version?

Correct!! - Id have allowed the 21 or the 21R was theres no difference twix the two in the image portion shown I dint think. But in this case it was the DB605B powered 21.   Your go @Boba Fett
