^ Good question, hard to answer.
Yes, but not like one we usually think of. The "..copter" is correct.
It is a "rotocraft" alright.

As said before this is a very unusual machine.

Is it a kind of a Gyrocopter ?

Almost, but the definition of a gyrocopter does not fit. The 'rotor' is not passive.
Sometimes described as a helicopter but this does not fit either.

As said before, the pioneers of aviation often used nature for ideas, like Etrich did with the Zanonia seed.

Big hint: In this case the object also has nature as a guide, like a seed. But not the Zanonia one ..

Simply ask: "French air_jet steered early copter" ... & voìla! get: Papin-Rouilly Gyroptere (Gyropter)

< methinks that gent needed a life preserver...BIG TIME!?? the gizmo was exceedingly unstable!

Quote:

....their monocopter was based on the sycamore seed;

a single blade extends from the seed to spin the seed and slow its descent as it falls. Even so, the machine was wildly out of balance, and the blade repeatedly contacted the water, damaging itself and shaking up the pilot. In addition, the 80 hp Le Rhone engine used was not powerful enough; the Gyroptere had been designed to use a 100 hp (75 kW) engine which could not be obtained. It helped also that I actually used to watch sycamore seeds swirling as a kid!

Looks like something Dr. Seuss would dream up.

re Aktungbby This is it

The "gyropter" from Papin and Rouilly, an early monocopter,
(https://en.wikipedia.org/wiki/Monocopter)
called Chrsysalide, idea based on the swinging and rotating sycamore seed.

The engine provided a strong airflow which was directed to the distal end of the big single plane and working like a jet to rotate it, a smaller tube was directed to a movable control "arm" to counter unwanted rotation and steer the thing, also with a (smaller) jet opening:

The pilot stood in a circular tub at the center of the centripetal forces, which was standing on roller bearings, while at the upper side was being held by the four bigger wheels that can be seen placed around the tub.
The rest of the apparatus was circling around the tub at a planned 60 rpm.....

A one hundred hp rotary LeRhône engine had been planned, and the 80 hp used proved to be too weak, it only provided 47 rpm instead of the needed 60, and the machine weighed 20 percent more than calculated.
The circular bottom part is a float, probably also used to internally distribute the airflow.

M. Papin (the gent in the french uniform seen on some of the photos) tried to start the Chrsysalide from a lake. It did not really take off (maybe saving his life), but sank.

A model of the machine:

It works as a small drone, electronically controlled for counterbalance.

Thanks for all partaking, i think this was quite a tough one

Over to Aktungbby!

What "monument" is this?

Cyborg322 · 08-31-22, 12:47 PM

Horse Block Duke of Wellington 1830

Jimbuna · 08-31-22, 12:54 PM

That's the one

Aktungbby · 08-31-22, 04:02 PM

damn! That was quick! The Duke's mounting block in Pall Mall London for getting off his destreyer (not Copenhagen?)at his club. Over to Cyborg322!

Aktungbby · 09-03-22, 12:53 AM

After a suitable delay, What's this?

Jimbuna · 09-03-22, 11:42 AM

Diesel engine?

Eichhörnchen · 09-03-22, 12:22 PM

A building?

mapuc · 09-03-22, 12:31 PM

It's part of a warship - I'm pretty sure it is

Catfish · 09-03-22, 02:19 PM

Electromagnetic gizmo?
