Aerospace and Mechanical Engineering2020<p>The paper presents approaches to computer-aided design of low-thrust thrust rocket engines using an extensive knowledge base that allows making basic technical decisions that determine the conceptual design of the engine, based on the developed algorithm of this process. The procedure of creating an electronic 3D-model of a low-thrust rocket engine fueled by gaseous oxygen-hydrogen in the environment of the graphical complex UNIGRAPHICS is described. 3D electronic models of the main elements of a rocket engine with a thrust of <em>P</em>=25N were obtained, with subsequent virtual assembly of all components, including the components comprised in the knowledge base, providing the development, among other things, of design documentation, creation of a production environment based on an electronic engine model, preparation for the product manufacturing and the manufacturing proper.</p>Ракетные двигатели малой тягикомпьютерное проектированиебаза знанийалгоритм проектирования3D электронные моделисреда графического пакетаконструкторская документацияLow-thrust rocket enginescomputer-aided designknowledge basedesign algorithm3D electronic modelsgraphic package environmentdesign documentation[1.
