Method of calculations and substantiation of requirements for engineering protection of critical infrastructure objects from UAVs with warheads

Abstract. Aim of the study. The purpose work is to develop a methodology for calculations and substantiation requirements elements engineering protection key infrastructure objects (KIO) electric power gas transportation systems Ukraine against UAVs "Shahed" type. Methodology. characteristics design UAV were considered. It has been established that "Shahed-136" type pose greatest danger, as they have largest warhead. For large and/or KIO structures, case direct hit by arrangement are substantiated principled solution first-order circular most important structures equipment proposed. includes two layers: protective screen an impenetrable shell. designed destroy or prematurely detonate its charge. shell, from which located at some distance, retain debris withstand wave explosion. Findings. method OKIS was obtained. sequence analytical methods both levels presented. When designing screen, concentrated impact collision calculated, shock pressure permeability calculated. Scientific innovation. proposed in first time. Practical value. A constructive developed process treatment plant hits using steel sand filling. procedure carrying out on installation system
