Aerospace Instrument-Making Annotation << Back Digital Engineering of Aerospace Devices and Products Based on the Manipulation of Precedent Sets of Data and Expert Knowledge Okhtilev M.Yu., Koromyslichenko V.N., Okhtilev P.A., Kuleshov A.V. In modern conditions, there is an urgent need to ensure the technological leadership of the Russian Federation in the aviation and space industries and the transition to an industrial model of conveyor production, which ensures accelerated market launch and increased serial production of competitive products. One of the priorities is the task of end-to-end digitalization of the stages and stages of the life cycle of aerospace products. This task should be solved from the very first stages of development - operational analysis, synthesis, development of options and selection of correct design solutions, for which the criticality and cost of errors are highest in the subsequent production, implementation and application of products. The basis of design and engineering decisions, in most practical cases, consists of poorly formalized explicit and implicit heterogeneous knowledge of unique (individual) specialists in the high-tech aerospace industry. In this regard, a particularly urgent scientific problem in this fi eld is the development of systematic scientific foundations, theoretical justification and appropriate special model-algorithmic and software-mathematical support (SMAPMO) for digitalization and replication., reuse of use cases of development solutions and expert knowledge in the framework of automation of conceptual digital engineering (design) and rapid prototyping of digital counterparts of promising aerospace products in a single information technology environment for prompt and correct selection, as well as semantic generation of the most promising and sound design solutions and their subsequent implementation. Purpose: to provide an overview of known solutions. Results: as a basic concept of one of the ways to optimize the design processes (sketch, technical) of promising samples of aerospace devices and products, to determine the requirements for them, as well as choosing their optimal confi gurations with the required tactical and technical characteristics, a transition is proposed from the traditionally used approaches of sequential research and development of technical solutions in manual mode based on the experience of designers to automated parallel design (engineering) of the conceptual appearance of promising products as part of interdisciplinary teams of diverse specialists in a single information technology environment. Keywords: conceptual digital engineering, aerospace products, integrated automation, parallel design, computer-aided design, digital twin, intelligent information and analytical technology, decision support, expert systems, integrated system modeling.
