Abstract


The subject of research is the process of developing a complete electronic product definition (CEPD) within the technical preparation system for the production of fixed-wing unmanned aerial vehicles (UAVs) under conditions of digital small-batch aerospace manufacturing. The relevance of the work is determined by the high intensity of design modernization, the reduction of the product life cycle, the need for rapid production reconfiguration, and the integration of digital manufacturing processes. Under such conditions, classical approaches to using the electronic product model (EPM) as a separate design model become insufficient for ensuring the integration of design, technological, and organizational preparation for production. This determines the need to form the CEPD as an integrated digital manufacturing environment. The purpose of the work is to develop a conceptual framework for the CEPD within the system of technical preparation for the production of fixed-wing UAVs and to determine the principles for integrating design, technological, organizational, and manufacturing data into a unified, coordinate-consistent digital contour. To achieve this goal, the following tasks were solved: the current state of digitalization of technical preparation of UAV production was analyzed; the differences between the concepts of electronic product model and complete electronic product definition were determined; the structure of the CEPD within the system of technical preparation of production was formed; the composition of the main information components of the CEPD was formalized; the role of digital coordinate alignment within the CEPD structure was investigated; and the features of CEPD integration into the digital manufacturing contour were determined. The research results demonstrate that the CEPD represents an integrated digital information environment that combines design, technological, organizational, manufacturing, and inspection data within a unified coordinate-consistent digital contour. A conceptual CEPD structure for fixed-wing UAVs was proposed, and relationships among the electronic product model, technological preparation for production, organizational preparation for production, technological tooling, digital coordinate alignment, and manufacturing data were formalized. It was shown that one of the key trends in modern UAV manufacturing is the transfer of accuracy assurance functions from the physical structure of technological tooling into the digital manufacturing contour based on digital coordinate alignment, virtual assembly, laser measurement systems, and digital geometry inspection. The conclusions confirm that the CEPD should be considered not as a separate digital product model, but as an integrated digital manufacturing environment that ensures the unity of design, technological, organizational, and manufacturing information within the system of technical preparation of UAV production. It was shown that the use of the CEPD creates the basis for the transition to adaptive digitally controlled manufacturing systems and implementation of jigless assembly methods in modern aerospace manufacturing. The scientific novelty of the work lies in the creation of a conceptual CEPD structure for fixed-wing UAVs within the system of technical preparation of production, which, unlike classical CAD/PDM approaches, ensures integration of design, technological, organizational, inspection, and manufacturing data within a unified coordinate-consistent digital environment. The concept of digital coordinate alignment in jigless UAV manufacturing was further developed through integration of virtual assembly, digital geometry inspection, and digital manufacturing data into the CEPD structure. The practical significance of the results lies in the possibility of applying the proposed solutions in the development of digital systems for technical preparation of UAV production, implementation of jigless assembly methods, development of reconfigurable manufacturing systems, formation of digital manufacturing environments, and integration of CAD/CAM/CAE/PLM systems in aerospace engineering
