Aerospace Instrument-Making Annotation << Back A Method for Assessing the Energy Parameters of Integrated Propulsion Systems of Space Rocket Boost Units Based on Telemetry Information Processing Results Gruzdev N.V., Pirukhin V.A., Krotova L.V., Shakmaev I.V., Spiridonov V.V. The article considers a technique that makes it possible to obtain estimates of the parameters of the combined propulsion systems of upper stages based on the analysis of telemetry information data of upper stages of various types. The implementation of the presented methodology in the BCVC hardware and software complex of the upper stage of a space rocket will allow for flexibility in the formation of payload launch schemes and more rational use of the components of the upper stage rocket fuel. Keywords: space rocket, combined propulsion systems, upper stage, telemetry information. DOI: 10.25791/aviakosmos.12.2025.1523 Pp. 03-13.
