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

Rapid prototyping has developed to the point that it can be used to print solid-fuel grains for hybrid rockets. Multijet modeling has been used by The Aerospace Corporation to print composite cell structures of acrylic filled with paraffin wax, allowing for both structural strength and fast regression rate. Grains of this kind show promise for applications such as small satellite or CubeSat thrusters. These grains, among other printed and cast designs, have been tested in the long grain center-perforated (LGCP) hybrid rocket motor at The Pennsylvania State University. Parameters such as chamber pressure, regression rate, and combustion efficiency were calculated to characterize each solid-fuel grain geometry. Focus was placed on designs in which swirl is induced within the grain through printed channels or vanes, but grains with swirl induced through oxidizer injection were also tested as a means of comparison and to further characterize the LGCP injectors. An experimental reduction technique was developed in SolidWorks to characterize regression rate and oxidizer mass flux for complex port geometries, which would otherwise be impossible to determine using conventional methods. Composite honeycomb grains were found to have regression rates comparable to cast paraffin wax standards and, depending on cell size, potentially much higher combustion efficiency. Swirl injection has been shown to produce increases of fuel regression rate around 30% in pure cast paraffin and 40% in cast paraffin with the addition of aluminum particles. In addition, grains containing turbulator vanes were shown to have regression rate enhancements similar to those of straight-port grains subjected to swirl injection.
