The background of the experiment and scientific discovery is as follows: Back in the 1980’s, the scientific director of Neila Technology Research Center, Yuri N. Ivanov, worked to understand the physical mechanisms underlying any type of motion which material objects can undergo.
At the same time he put forward a hypothesis about the mechanism corresponding to the influence of the gravitational field on material bodies. According to this hypothesis, the gravitational field of the Earth affects all material bodies in such a way that a mismatch of phases and frequencies of oscillating atoms occurs in the crystal lattice of the body. As a result, any material body begins to move with the acceleration of free fall to the surface of the Earth.
The task was to experimentally substantiate this hypothesized mechanism of action of the gravitational field upon material bodies from the perspective of Rhythmodynamics and also to prove that it is fundamentally possible to create a non-reactive propulsive force simply by changing the phase and frequency parameters of the system.
In 2015, experiments were carried out with a boat that moved in a pool due to the phase shift of interfering ultrasonic waves emitted from two piezo-emitters installed on the hull of the boat. For this experiment, a plastic boat was utilized, on the bottom of which two counter-directed piezoelectric emitters were placed.
On the upper part of the hull a two-channel signal generator was placed, which generated signals for the piezoelectric emitters. After that, the boat was placed in the water and both piezo-emitters were given signals which were in phase and with the same frequency.
As a result of interference between the emitters, ultrasonic standing waves were created. If the emitters worked in phase, the boat maintained a state of rest on the water. But if the generator created a small phase shift of several degrees, the boat began to move on the water surface.
