This principle in general is known as method of transformation of rotational motion of mass (working body) into translation motion of the system. Experimental unit was designed in our laboratory. After testing of the system it was confirmed that it is possible to create unidirectional thrust (propulsion force) by means of vortex principle.
Our company Faraday Lab Ltd filled Russian Federation patent claim #2002128658 of October 25, 2002. It describes METHOD AND DEVICE TO CREATE PROPULSION FORCE BY MEANS OF TRANSFORMATION OF ROTATIONAL MOTION INTO TRANSLATIONAL MOTION.
Water (about 100 g) inside of the system is rotating by electromotor. By means of special trajectory (helical spire) the thrust can be produced for the system without reactive mass flow.
Both rotational and linear propulsion momentums are produced here but by means of application of two similar systems (with counter-directed rotation) as one engine it is possible to compensate rotational momentum and to get unidirectional thrust only.
