Propellers' frame: Russia came up with an unexpected car protection system from drones
As an example, the drawing depicted a minibus of the type "loaf" with seven screws: four right and left, one in front, back and on the roof. When rotating, the screws should affect shock drones that are trying to attack transport. According to the developers, it is difficult for the operator to notice the rotation of the blades and their boundaries, so it is likely that UAV will eventually get into one of the zones.
"In the gap between the housing of the vehicle 10 and rotating shovels, a cumulative grenade will be reversed (after a shovel on the grenade body). The gap is also necessary to weaken the cumulative jet in the event of a blanket of the UAK. According to Russian engineers, they allegedly conducted tests on the layout and proved that the system reliably reflects grenades. To do this, the length of each blade should be at least 1 meter, and the speed of rotation: 600 revolutions per minute.
