The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

RESUMO

This paper describes the theoretical analysis and experimental research work on the effect of solid fillers on composite propellant mechanical and rheological properties. The theory of the polymer rheology has been applied to model the polymer properties. The theory is extended to the composite propellants comprising a polymer binder filled with solid oxidizer and metallic fuel. The variation in oxidizer particle size and its distribution has been studied experimentally to analyze the effect on performance properties. The results of propellant viscosity and mechanical properties have been measured and discussed. It was concluded that fine ammonium perchlorate (AP) particles act as active fillers and enhance the mechanical properties of composite propellants. Viscosity decreases with an increase in the amount of fine AP particles and then starts increasing when fine proportion increases beyond ~20−25%. Similarly, elongation increases with an increase in fine AP particle size and maximum value is obtained at fine AP contents of ~25−35%. The size of the AP mean diameter also affects the mechanical properties. Both mechanical strength and elongation substantially decrease as the mean AP particle size increases.
