Today, a significant threat to critical infrastructure facilities is posed by attacks of unmanned aerial vehicles of various types. The study considers the behavior of protective mesh fencings designed to capture and stop these aircraft at a safe distance from a protected facility, considering the potential detonation of their warheads. A methodology of calculation of the behavior of protective mesh fencings that is necessary at the design stage in order to determine the strength characteristics and structural features of frames to which protective mesh screens are connected has been presented.
The results of physical experiments have been provided; the mathematical calculations have been described. It has been shown that the mesh kinematic parameters under the impact of a falling object can be successfully modelled by mathematical models based on equations describing transverse vibrations of the membrane.
Comparing the results of numerical and physical experiments has shown that the discrepancies between them are within 5–8 %, which proves the mathematical model's reliability and the possibility of its use to forecast the behavior of protective mesh fencings under the impact of unmanned aerial vehicles.
The completed verification of mathematical and physical models helps to significantly reduce the volume of studies and field tests of protective mesh fencings.
The obtained results can be used as a basis for methodologies to design protective mesh fencings and develop regulatory requirements for identifying minimum distances of their allocation from protected facilities.
