This inventer molds the contours of the Magnus cylinder with shape changing surfaces. These small. Moving parts permit the Magnus cylinder to react like variable pitch propellers. A skin coated with piezo chips would allow shape shifting capability.
.
Thanks to Peter we can conceive of a ring composed of shape shifting piezo electric material. A piezo strip would greatly increase the wind generation output of the cycloidal wing. A roller motion would increase the lift like the fabric job. We can program piezo arrays to "Screw" around the ring!

3 piezo elements under a stretching fabric would be enough to control the ring. A dozen or more perhaps could be programed to produce a spiraling effect on the surface of an elastic wing?

Elon Musk could cover his rocket with a piezo ceramic heat shield material that could generate lift with a spiraling Magnus wing program!

The composites operate at 1000 degrees centigrade. Rentry heat can be double that so it would need to cool down before it would work on the way back down. It would help generate lift on launch.


Baked over a mesh of electrodes the ceramic composite would generate power from the heat of rentry.

You are too fast,synchro1 !
Each evolutive/innovative step has to be researched : efficiency in-/decrease !
Universal use or only appropriate for land/sea/air/submarin use !?

Are there publicated experiments,studies,working prototipes ?

DE3217763 german experimenter Herbert Borreck
https://worldwide.espacenet.com/patent/search/family/006163320/publication/DE3217763A1?q=pn%3DDE3217763A1

Not only 1 tube/cylinder but two beside ,advantage ?
What do we know about Anton Flettners applied one/two cylinders experiment results ?


I think and decide with thousands of inventor mosaics/scientifical prototips knowledge in mind and concern

And when I am interested in good ideas so I try to come in contact with the idea-holder ,so also with Peter Ferger,phone-conversation about the idea/material/-deliverer/-producer and prices ,between years  2000 -2005
I do not see any barrier to not to do good conversations foor fruitable results for both sides !
Only one time in my life I got stopped : when by a phone-call,in the interest to speak with Dr.Wolfgang Volkrodt(very productive engineer and patent holder,Ex-Siemens) ,I only got his widow on call and she after some minutes
gave me the advice to come in contact with a friend from Dr.Volkrodt :

living in Kiel,his Name : v.Klitzing  :o
I am really ashamed,to knock on the door from a Physics-Nobel-Prize award-holder ! ::)

Before I converse with individuals I do my theme-related homework and for Nobel-award level I would have to do
more !

One can see from this article that a piezo matrix works well as a wing shaper material : The idea would be to program the piezo matrix to roll spirals around the cylinder.

This may have real value at this point. Picture hexagonal heat shield ceramic tiles mounted on simple piezo benders.
Intelligent control can orchestrate a spiral lift pattern by flapping them in programed sequence. Musk could remove the fins and control the rocket with the tiny gimbaled heat shield fins. The piezo actuators can withstand the high heat behind the shield.

Here's a sketch for a twin rubber band model that mounts both counter wound bands in the middle : Positioning the cylinder band grommet aft of the the collar bearing by braces gives the rubber band a secure place to anchor and spin.

The tube through which the rubber band passes mounts to the inside rim of the frame tube at the rear. The inside of the collar bearing mounts on the tube.

It would be fun to 3D print this twin rubber band model.

Attaching a cycloidal ring wing around the blade ends of the rear propeller would quadruple the lift of the the coaxial propellers!

The difference between blade spacing and blade pitch angle is critical. The Cyclo rotor shell is not a propeller duct but prop pitch and spacing remain critical.

This kind of coaxial gear can run the counter spinning rotor wing with one rubber band : The rear prop should have a deeper pitch to power the rotor wing. The front prop can help power the rotor wing with it's exhaust.


Lift is a factor of cubic meters of air over square meters of wing area.

Removing the top and bottom of the Pepsi can but leaving a little bit on each end to support the rubber band and propeller would improve the flight distance and speed. Take note of the spiral twist in the fins.

Nesting the propeller by ducting it inside the rim of the cycloidal wing would help. Simply recessing a stick frame inside the can and using a smaller propeller or moving to an Oatmeal container would work!
