Russia is testing infrasonic six-rotor drones

Russia conducted an experiment with a six-rotor helicopter (hexacopter) that uses infrasonic waves on a group of 100 volunteers.

The march called Chershen, if successful, will be presented to the Ministry of Defense and other law enforcement agencies of Russia.

This was stated by Vitaly Dolgov, head of the unmanned aviation laboratory at the Kartsev Research Institute, in an interview with the Russian news agency TASS. He said: “First, auditory sounds were reproduced, then the number of vibrations in the signal was reduced in order to find out the frequency that a person does not hear, but rather feels discomfort or some kind of discomfort from it.

The head of the laboratory explained that the use of a sound march does not harm human health, but causes disturbing temporary effects, and when people are exposed to these sound effects, they feel uncomfortable and want to leave the place.

Vitaly Dolgov added that the use of inaudible waves is similar to seasickness, which causes nausea and dizziness. All symptoms disappear as soon as the person leaves the area where the march is flying.
