Abstract

Background. Modern solid propellants are widely used in various propulsion systems, where their performance is determined not only by energetic characteristics but also by the properties of binder systems that ensure structural integrity and stability of the propellant grain.
Objective. The aim of this study is to analyze modern binders for solid propellants and to develop an approach to selecting effective compositions based on both physicochemical and mechanical characteristics.
Methods. The study is based on the analysis and generalization of current binder systems used in solid propellants, including thermosetting and thermoplastic binders, with consideration of their influence on mechanical behavior, structural integrity, and operational performance.
Results. It is shown that binder properties significantly affect not only the energetic performance but also the mechanical strength, deformation resistance, and reliability of propellant grains under operational conditions. An integrated approach to the selection of binder systems is proposed, which combines energy-based and mechanical criteria.
Conclusions. The proposed approach allows for a more comprehensive evaluation of solid propellant efficiency and can be used in the design and development of advanced propulsion systems with improved performance and reliability.
