Обоснование критерия эффективности при формировании технического облика беспилотного воздушного судна вертолетного типа

This article discusses the rationale for the criterion of efficiency in the formation of the technical appearance of an unmanned aircraft of a helicopter type. Analyzed the criteria for the effectiveness of the use of an unmanned aircraft of a helicopter type, such as relative weight, flight time, unit cost of flight, life cycle cost. The necessity of using a combined criterion that takes into account economic and functional efficiency has been identified and justified. Variable, non-variable, and uncertain parameters characterizing a helicopter-type unmanned aircraft are formulated. We consider the formulation of the optimization problem of determining the technical appearance. The process of forming a technical appearance is based on three interrelated processes: aerodynamic layout; volume-mass layout and structural-power layout. On the basis of the justification carried out, the author proposed a method for determining the rational appearance of an unmanned aircraft of a helicopter type, taking into account the accepted restrictions.
