Aerospace and Mechanical Engineering2022<p>The goal of the work is to research the case of isotopy of spacecraft compartments in the problem of on-board equipment location. A definition of this engineering topological property is given in the article. The most frequently used spacecraft compartment hull shapes and various compositions of their casings are considered. Also, general strategies of taking decisions that determine the choice of modeling technologies and performance factors are discussed. A method of comparing various layouts on the strength of the object location performance factors was developed. The problem of on-board equipment accommodation is solved. Generalized mathematical models of performance factors are presented. Design models and diagrams are constructed. The results obtained make it possible to upgrade algorithms of accommodation.</p>Конструкция отсека космического аппаратаразмещение бортовой аппаратурыкомпоновка бортовых системкосмический аппаратформа корпусабортовая аппаратурапоказатель эффективностиSpacecraft compartment designaccommodation of on-board equipmentlayout of on-board systemsspacecrafthull shapeon-board equipmentperformance factor[Kozlov D.I., Anshakov G.P., Agarkov V.F., Antonov Yu.G., Kozlov V.D., Chechin A.V., Fomin G.E.
