as a device for propelling a mass,when rotated with a continuous variable/pulsatory velocity ,produces by its interplay with the inertial property of space,a pulsatory thrust approximately perpendicular to its plane of rotation.
The basic, prime design you can find at www.geocities.com/iacob_alex then click on "Some_Drafts"/text046.jpg with the title "Pulsatory Screw".

.....but not as a simple "copy".
We can play four eccentered masses as an inertial equivalence of an air drone (propeller),so to obtain a semi-space linear pulsatory tractive vector !

Usually , a propeller is a mechanical device for propelling a boat or aorcraft , consisting of a revolving shaft with two or more broad angled blades attached to it.
This time , an inertial "propeller"(transportation rotor) is imagined as a mechanical device for propelling a mass (....) , consisting of a revolving shaft with two or more curved variable levers .
On the same line , there are a lot of proposals (patents) , at :

Take a look at "Similar Documents" (in the same place) , also...
