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

Краткое описание

The different ingredients in triple-base propellants have different physical properties, such as their water solubility. The solubility of nitroguanidine is 10.36 g per 100 g water at a temperature of 373.15 K, but the solubility of other ingredients in triple-base propellants is negligible. In this paper, the effects of hot water on triple-base propellants were investigated as a function of time. The combustion performance of these propellants after water immersions was also examined. Immersion in hot water led to the formation of micro-holes in the surface layer, and the depth value range of the immersion layer in the propellant was 50−150 µm after water immersion for different times up to 60 min. Closed-bomb tests indicated that the combustion time decreased as the propellant immersion time increased. Additionally, hot water immersion can also decrease the combustion ignition pressure of the propellants.
