Inertial Pulsatory Propeller...

[iacob alex]

     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...
