In this case the force is created as result of air pressure gradient,
that is determined by difference in relative velocity between wing surfaces
and air.
There is no reactive flow in such sort system and this idea can be used
for spacecraft propulsion also. In closed system air or liquid circulation
can be created by fan or pump, Fig.2
The wing here is connected with body of system. Many wings can be installed in radial superposition with some distance. Rotation velocity for liquid should be less than the velocity for air flow.
Other kind of the same system can be designed to use described above pressure gradient, Fig.3, that is produced when different relative velocities between liquid (gas or plasma or Ether) and two sides of the rotor is created.
Fig.3
In such sort closed system the force that is acting to the wing is
active and it should be demonstrate itself as reactionless propulsion force
in axial direction. This closed system can be used as drive for any type
of transport.
There are also some methods to create ionized gas (plasma) circulation and in this case the metal or dielectrical wing that is electrically charged is powerful source of lofting force.
In general case, that is described in my papers
, rotation of electrically charged wing also is the way for active
force since by this way the gradient of Ether pressure can be created.
