So, what exactly is the advantage? That this could fly and harvest your crops at the same time?

PS: do you have more info about GYROPTERE CHAPPEDELAINE ?? (like 3 views, internal construction etc.)
 
Hi Everyone!

I seem to recall that there was a lighter-than-air aircraft design that would use this same (or a similar) concept. It was at least 10 years ago that this particular idea came out, and I think that it even appeared in Aviation Week.
Does anyone else recall this?

You left out one of the early helicopter pioneers, Haviland Platt, who had patented a Cyclogyro several years before moving on to helicopters such as the Platt-LePage XR-1.

Hi,

Prof. Frederick Kurt Kirsten design a cycloplane it was supported
by William Boeing.

.....and if you take one, and stick it in water, it's called a "Voight-Schneider Propeller" (sometimes spelled "Voith-Schneider"):

Hello boys

thank you for pointing to my Bestiaire.
The Chappedelaine Gyroptère I would not class as a cyclogyro. Rather I would see in it an elder predecessor of Wibault's Gyroptère which as you know finally materialised as the Hawker P1127 (after some soul-searching , I admit).

I did a larger article on the Gyroptère with some help from the Chappedelaine family in Air Magazine n°40 (February 2008) (in French but with more pictures)

I hope this helps

This cycloidal drive is in actually use on tugboats.

one question

have they real build that as experimental Aircraft and has the pilot survived the testfight ?
 
But no, Rochbach airplane seems exit from "Stop the Pigeon" !!!! ;D ;D
"Mutley make something !" :D :D

You are actually refering to the excellent "Dastardly and Muttley" cartoon, as it was called in the U.S. (in French it was "Satanas et Diabolo"!). And, yes, it DOES look like something straight from that wacky show...
 
Hi,

was that concept relate to cyclogyro ?.

Hi,

here is a wingless cylinder plane.

:eek: Whatever the virtues of that configuration, didn't anyone with some common sense suggest that the hanger space needed for one single aircraft wasn't even worth the try?? ::)
 
Two ducted fans combined with a conventional fuselage. Early shape of the
later BTZ Lucane or Nord 500. Interesting to see, that the idea was already
there in 1934 !
But perhaps we should move the last two designs in a separate thread, as they
have nothing to with the principle of Cyclogyros aircraft ?
 
I've seen a cyclogyro kite, with a pair of axially pivotted 'wings' set at a fair dihedral. It flew well in the light breeze, and attracted a lot of stares...
 
As you've mentioned it .... something like that ?
Bought it (just for my son, of course ! ;D ) two years ago. Was a remembrance
to the one, I had about 40 years ago.

Oh I remember these now! Used to have them as a kid when we went to the seaside! So they're still doing that stuff... A Cyclogyro of sorts I guess, yeah... ;)
 
Here's what appears to be another image of Dr Kirsten's gyroplane; the cover is dated November 1934. During the war the Air Materiel Comd was asked to evaluate a paper proposal for a fighter cycloplane, and it's very likely that Dr Kirtsten was the source of the proposal. I have a copy of the report, but for the moment I can't figure out what I did w/it. Will post as soon as it turns up.

Yup, that's it. IIRC, the report said in so many words that the idea was interesting, but impractical due to very likely problems with airfoil flutter, instability and power transmission inefficiencies.

Did the report come with drawings, or just art?

Also: I *think* the art was by Tremulis, the feller who designed the "zero fighter" and the Tucker.

I'm a little skeptical of Fanwing's claims. What makes this technology more efficient than a conventional helicopter? On the face of it, the complicated flow path through the vanes rotating inside the wing and then over the wing would seem like a draggier way to accomplish the same thing as a rotor disk. The fanwing would seem also to require heavier construction than a rotor - the whole thing would have to be much more rigid than a typical helicopter rotor to prevent mechanical interference.
The basic architecture might be better suited to high speeds than a helicopter, but I'd think moving beyond helicopter speeds would require closing up the wing and switching to some other propulsive mode, making it a sort of compound aircraft.
Pure speculation, but Fanwing's website doesn't provide a lot of detail to work with (especially for a technology that they've been tinkering with for 20 years).

It should be added, that this concepts is from 1899, maybe astonishing, due to the relatively
modern look of fuselage and tail. Ludwig Rüb actually started development of his "Schaufelradfliegers"
(paddle wheel flyer). He was financially supported by Ferdinand Graf Zeppelin, maybe another surprise,
who, during the same period was constantly plagued by shortage of money himself !

Thank you my dear Jemiba for this info very much.
