.....as a circus performance , at : https://youtu.be/SebDLxMORZs (https://youtu.be/SebDLxMORZs)
as a concept , at : http://web.mit.edu/angles2008/angles_Jacob_Sharpe.html (http://web.mit.edu/angles2008/angles_Jacob_Sharpe.html)
as a simplified mechanical "composition" if we take a look at :

.....but , we retain two spare parts (1 and 2 ) only ...and take out the vane (3-4-3) ,replacing this rotor with another one...a kind of vise handle (rotating and sliding ) bar , as :

.....and play it "double"( in "mirror"...) , can we get across with a "clean" pulsatory one-way centrifugal thrust ? !
Two counter-rotating-sliding vise handles...as an "inertial propeller" ?!

Hi Jerry !
Take a look at :

They have some common first lines ( two rotating-sliding masses ) with :

My proposal was a minor change ( 3-4-3 as a single mass...) of rotor , with :

Hi Jerry !
Long time ago , it was inter-corporate forum/inertial propulsion...and the inertial "sailor"...I remember with pleasure ,but regretfully...and a non-tested model :

Now , starting with a counter-rotating propellers logo :
https://en.m.wikipedia.org/wiki/Counter-rotating_propellers#/media/File%3ACounter-rotating_propellers.gif (https://en.m.wikipedia.org/wiki/Counter-rotating_propellers#/media/File%3ACounter-rotating_propellers.gif)
...as a symbol to identify the "essentially" motion , we can develop a simple logo for centrifugal propulsion:two counter- rotating- sliding masses (rods) , with an one-way thrust , as a summary.
