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

要約

Hybrid propulsion is a promising alternative for space propulsion; however, due to the low regression rate and hence low thrust levels of the classic polymeric fuels, new alternatives are sought. In recent years, liquefying, paraffin-based fuels have been investigated for their much higher regression rate compared to that of polymeric fuels. This paper presents experimental and theoretical research conducted at the Technion. Both plain paraffin fuel and paraffin-polymer mixtures have been tested. Plain paraffin exhibits a high regression rate but poor mechanical properties. The addition of polymer improves the mechanical properties but lowers the regression rate compared to plain paraffin fuel. Nevertheless, it indicates a promising direction to pursue a relatively high burning rate fuel of good mechanical properties. A model accounting for heat and mass transfer in the presence of liquefying fuel has been developed to predict the regression rate of the paraffin-based fuel. The model developed includes an additional mass loss mechanism, i.e., the liquid melt flowing along the grain. It is shown that this mechanism might have a noticeable effect on the overall regression rate and a potential for decreasing system performance. The test results exhibit good correlation with the model predictions.
