The article deals with the problem of selection of the optimal design parameters (image characteristics of UAV), whose aim is to achieve an object with not precisely known coordinates, and not precisely known speed. The quality of UAV is valued by two optimality criteria: the probability of target detection and the required fuel reserve. This problem is solved in conditions of uncertainty, due to the influence of uncontrollable factors, for each version of the design solutions possible value options of uncontrollable factors are get over, which are set in the area defined by the technical specification requirements. The implementation of the stability conditions is carried out by means of a specially constructed sample. The sample consists of options for the design decisions. For each alternative design solution statistical tests are conducted, each of them is characterized by the corresponding values of the vector of uncontrollable factors. According to the system of motion equations of the UAV without the roll in half-rate projections on the axes of the coordinate system with a stationary atmosphere the aerodeon model of UAV is presented. Based on the aerodeon model of UAV the image characteristics of UAV resistant to multi-factor uncertainty are optimized. The results are used in the development of algorithms and programs with the numerical solution of the statistical information and synthesis problems for the selection of design solutions resistant to uncertainty factor in the development of UAV.
