ON THE PROBLEM OF FORMING THE APPEARANCE OF PROMISING UNMANNED AERIAL VEHICLES
Abstract
Background. The widespread use of unmanned aerial vehicles (UAVs) as individual products, and especially in the complex solution of a complex multi-purpose task, is provided by the development of technology and technology. However, it is the multiplicity of options for the use of UAVs that gives rise to the problem of forming a not redundant, but sufficient configuration of each individual product, which is associated with the problem of forming the so-called appearance of promising UAVs. In the work, taking into account the accepted initial conditions, restrictions and assumptions, the problem of optimizing the choice of the appearance of a multi-purpose UAV system was solved on the basis of the cost of fulfilling the target tasks that are solved during the operation of the UAV. The definition of the basic version of the multi-purpose UAV system is given in the form of a set (vector) of UAV design parameters that are part of the system. Materials and methods. The problem posed belongs to the class of problems of multi-criteria multi-parametric multi-factor identification of indicators and characteristics of complex organizational and technical systems and their structural and parametric optimization. The problem is solved on the basis of a system analysis of the operating conditions of the UAV by the method of mathematical modeling (including simulation). The substantiation and choice of the appearance of design vectors of parameters and the definition of key characteristics (options) for the creation (modernization) of a multi-purpose UAV system in the conditions of a multidimensional heterogeneous set of target national economic tasks are carried out. Results. The choice of the vector of design parameters of the multi-purpose dual-purpose UAV (DN) system makes it possible to determine the modification of each individual type of UAV, namely the design features and performance characteristics of the UAV DN. Conclusions. Based on the analysis of the functioning of a system of several types of UAVs designed to serve a variety of purposes, the configuration (appearance) of this system is determined, which, under the conditions of the assumptions made and the initial conditions of operation, allows solving target tasks with maximum probability and minimum cost. The problem is solved taking into account the structural features, design and functional restrictions on the parameters of the UAVs used.
