Methodology for Determining the Probability of Damage to UAV as a Result of Exposure to Atmospheric Environmental Factors

Introduction. For the effective use of unmanned aerial vehicles (UAV), it is required to take into account impact atmospheric environmental factors. Based on existing level development research and methodological apparatus, impossible determine probability damage UAV under conditions complex exposure factors assess feasibility further performance flight task. Violation operation process caused by influence precipitation, wind temperature environment. The work aims at a methodology for determining as result factors, well evaluate software package implementing developed algorithm using triangular, trapezoidal, pentagonal, Gaussian membership functions. Materials Methods. A technique proposed that makes possible, theory fuzzy logic, with inaccuracies uncertainties in description effects It takes possible forcing enables various influences. computational complexity depends significantly number qualitative assessments impacts UAV. Results. method based sets (triangular, Gaussian) was tested. estimating application environment described. An experiment carried out calculating conditions: «moderate conditions» speed 3 m/s, precipitation intensity 0.8 mm/h, air 5 °C; «very heavy external 12 3.5 –6 ºС. established triangular functions calculate provided higher compared rest ones (trapezoidal, Gaussian). Discussion Conclusions. values probabilities obtained during implementation influences can be used pre-flight preparation stage analysis considered forms functions, recommendations their are given. algorithms will provide high control systems (UAV CS).
