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

ABSTRAKT

A highly filled multiperforated gun propellant containing predominately RDX was spray coated on its surface with cellulose acetate butyrate (CAB). The coating thickness was either 1 or 2.4% by weight. The purpose of the coating was to lower the initial maximum peak pressure and impart a progressive burn rate to the gun propellant grains. The coated and uncoated propellant grains were combusted in a closed bomb. Pressure-time combustion curves were obtained. The homogeneity and thickness of the coatings were measured from photomicrographs and x-ray maps obtained using a differentially pumped scanning electron microscope (WET-SEM) equipped with a light element energy dispersive x-ray detector (EDS). The SEM and closed bomb results showed that the initial pressure-time ballistic traces could be lowered and retarded as a function of coating thickness.
