UAZ-452 ‘Bukhanka’ with propellers: Russia patents new anti-drone device

Russia has patented an anti-drone device for the UAZ-452 ‘Bukhanka’ vehicles.

Armored vehicle analyst Andrei_bt reported that the system consists of special sets of propellers with electric motors.

The design is a frame that can be mounted on the body of a vehicle.

At least one electric motor with blades on the shaft is mounted on this frame, and the motors can be connected to the vehicle’s power supply.

Mechanical impact on FPV drones is achieved by rotating blades.

“Due to poor communication, it is difficult for the UAV operator to identify the rotation of the blades and their limits on the monitor,” the patent author notes.

According to the design, when attempting to attack a protected vehicle, the drone is likely to enter the rotation zone of one of the blades.

In the gap between the vehicle body and the rotating blades, the shaped charge will turn around after hitting the body or the blade itself.

This gap is also necessary to weaken the cumulative jet in case the UAV charge explodes upon contact with the blades.

The tests of the prototype showed that rotating the blades at a speed of 600 RPM with a blade length of 1 meter ensures effective interception of grenades.

“Increasing the blade rotation speed increases the effectiveness of countering high-speed UAVs,” the developer noted.

Sometimes Russian assault troops even use Bukhankas to storm Ukrainian positions. One such assault was repelled by the Achilles UAV battalion of the 92nd Assault Brigade in the Kupiansk sector.
