Aerospace Instrument-Making Annotation << Back Method for Predicting the Remaining Life of Technological Equipment Based on the Observed Parameter of the Failure Flow Lyashevsky A.V., Astankov А.М., Suvorov А.N., Golovchinskaya N.V. The article considers the main factors that have the most significant impact on the functioning of technological equipment of ground-based space infrastructure facilities, as well as the types of its failures. The technical feasibility of forecasting the residual life of technological equipment elements of ground-based space infrastructure facilities, the implementation of measures for timely partial replacement and repair of elements, the result of which is an increase in the service life of ground-based space structures, is shown. The relevance of the development of a methodology for predicting the residual life of technological equipment elements of ground-based space infrastructure facilities based on the observed parameters of the failure fl ow is substantiated. Based on the presented methodology, calculations of the values of the residual gamma-percent resource and its lower confidence limit were performed on a specific example of the initial data, allowing us to conclude about the technical condition of the element of the ground-based space infrastructure object and its service life. The practical significance of the methodology presented in the work is shown. Keywords: residual resource, forecasting, technological equipment, residual gamma percentage resource, lower confidence limit. DOI: 10.25791/aviakosmos.2.2025.1463 Pp. 47-55.
