Unmanned Aerial Vehicle Flight Risk Assessment Model for Environmental Research on Mountain Terrain

A study was conducted on the current problem of developing a fuzzy model for assessing the risks of Unmanned Aerial Vehicle (UAV) flights in mountainous terrain, taking into account risk-oriented factors influencing the flight. As a result, we obtained a quantitative assessment of flight risk and a linguistic interpretation of the level of safety of UAV flight, which will allow a reasonable approach to decision support. For the first time, the study proposed fuzzification of input data using a multidimensional membership function, presented in the form of linguistic estimates of the probability of a risk event and quantitative estimates of the number of “reliability” of the ground control manager's conclusions in his conclusions. For the first time, a generalized step-by-step algorithm for obtaining a quantitative assessment of flight risk and a linguistic interpretation of the level of safety of UAV flight have been constructed. Experimental approbation and verification of the conducted research on test data of UAV flight simulation are carried out. The study will be a useful tool to support safe decisions about UAV flight in different mountainous terrain
