Abstract

Nowadays, the production of unmanned aerial vehicles (UAVs) outside of serial production is an urgent task. There is a need for the manufacture of such devices of various schemes, sizes and intended purpose. Aircraft-type UAVs (monoplanes and biplanes) are more difficult to manufacture. As a rule, they are single-use devices. Therefore, such devices should have a simple design, be light enough, have minimal radio visibility and a number of other properties that are necessary for conventional flying apparatus. Composites (glass and carbon plastics) are materials that largely meet the specified requirements. But for these materials, it is necessary to use special structural and manufacturing solutions (SMS) during the technical preparation of their production (TPP) (production of aerodynamic surfaces, assembly and joining of parts, aggregates into a structure). Quite a lot of such solutions are known, but their optimal selection and combination of individual SMS in the UAV depends significantly on the purpose of the UAV, the volume of production, production conditions and, in general, on the production goals.The purpose of this work is to develop a mathematical model for quality management of technical preparation for the production of UAVs. It is the quality of the technical preparation of the production that determines the quality of the manufactured products and the effect of the production itself.The work gives a general diagram of UAV manufacturing processes. The inextricable connection between the design and technological parts of technical training was noted. The multi-iteration process of developing optimal production processes, which depend on its various goals, is shown. The systematicity, compactness, and reasonableness of the solutions are determined by taking into account many properties of technical processes and the conditions of their implementation. The consideration of possibilities in computer-aided design is sufficiently substantiated. For its implementation, a complex model of quality management of technical training is required. The qualitative approach to model synthesis meets the conditions of complexity and reasonableness.As an example of multi-variability, the SMS of the manufacture of the wing (bearing surfaces) and their connection with the fuselage is considered.The original feature of the proposed mat model is the use as a control parameter of the weighting factor of one or another property of the SMS, which depends on the set goal.The mechanism of distortion of given aerodynamic shapes of bearing surfaces, which are made of polymer composites, when they are supported by various structural elements (spars, stringer frames, fittings) is described. Such residual deformations lead to deterioration of aerodynamic quality and strength.The scientific novelty of the work consists in the synthesis of a mat model of quality management of technical preparation for the manufacture of UAVs. The practical value of the work is determined by the given number of examples of SMS variants of different levels.
