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

For several years research has been carried out with the hope of producing gun propellants that have temperature-independent burning behavior through the use of Dinitrodiazaalkanes C36H92N40O40 (DNDA-57) nitramine fractions in the formulation, although the mechanism that causes this behavior is not clear. In previous studies, it was known that pressure oscillations occur in hole channels of gun propellant grains that can lead to modifications of the burning rate and to an accelerated burning under specific conditions. To analyze the impact of such oscillations on the burning behavior of DNDA powders, tests with DNDA-57 powder formulations were performed in a closed vessel. It has been demonstrated that the oscillations have a determining influence on the temperature behavior.
