Introduction. During a special military operation, unmanned aerial vehicles (UAVs) are actively used by the enemy to attack industrial and energy facilities of the Russian Federation. One of the most effective ways to protect objects from UAVs is the use of enclosing structures using trapping nets. They make it possible to prevent the UAV from contacting the enclosing structures of a building or structure and minimize the consequences of an explosive charge explosion. Research methods. Calculation methods based on the formulas of M.A. Sadovsky were used to determine the permissible distances from the UAV-trapping grids to the enclosing structures of the object. The deflection of the grids was determined by the calculation method by solving a partial differential equation describing the transverse vibrations of the membrane.
Objective: To determine the possibility of using mesh structures to prevent damage to industrial, energy and civil facilities by damaging explosive explosion factors carried by UAVs. Tasks. Selection and justification of calculation methods for assessing the degree of damage by an explosive charge to the protected object and the magnitude of the deflection of the grids during an attack of the UAV; calculation of the permissible distance from the trapping mesh structures to the enclosing structures of a building or structure; assessment of the deflection of the grids under the dynamic influence of the UAV. Results. Calculations performed within the framework of the study made it possible to determine the permissible distances from the trapping mesh structures to a building or structure with different explosive masses; the deflection values of the grids under the dynamic influence of UAVS on them. Conclusions. The calculations of the distance from the trapping mesh structures to the protected objects made it possible to identify the effectiveness of this method of ensuring security in the event of a UAV attack. The materials of grids and structures of supporting elements used in construction make it possible to implement physical (passive) protection against UAVS in practice.
