  2.9. Restoration of force elements in a working condition

 

In a Fig. 25 the scheme of restoration of the FE (Force Elements) is presented to a working condition. In figure:

a-b) the Running cycle. Mobile elements gather in a final point of a trajectory;

c) Moving the collected mobile elements to the center of a trajectory;

d-e) Accommodation of mobile elements on a working trajectory and giving of speed by it.

Red color designates moving the center of mass of system of mobile elements.

For reduction of time of restoration of the FE and for preservation of a part of kinetic energy of mobile elements, it is possible to make a conclusion of mobile elements to a working trajectory during a running cycle (Fig. 26). In that case, practically at once after end of a running cycle it is possible to begin a new running cycle.

In a Fig. 25 and Fig. 26 are presented variants of restoration of the FE with reduction of mass of mobile elements. For the FE with increase in mass of mobile elements (Fig. 22) principles of restoration practically same, only varies a direction of gathering and dispersal of mobile elements.

 

There is an opportunity of association in one force block of the FE with increase () and reduction () mass of mobile elements (Fig. 27).

In a Fig. 27:

      a-b) the right part of the FE (on fig.) works, as the FE;

      c) Transition of mobile elements;

      d-f) the left part of the FE works, as the FE ;

      f-g) the left part of the FE works, as the FE, transition to.

Force element with indemnification of a momentum on one of coordinates and indemnification of the moment of a momentum:

The center of mass of mobile elements is shown by red color.

It is necessary to make a reservation at once, that such association is possible only: or for a single FE, or for group of the FE with zero phase shift. As a total momentum of mobile elements in the FE and in the FE, if their phases it are equal among themselves, equal to zero.

In a Fig. 28 overlapping the FE is presented and  the FE with an identical phase.

If and linear momentum of two systems of mobile elements to equally linear momentum of one, moving on a circle, in regular intervals allocated mass.
