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

The paper deals with the prediction of the performance of modern types of ETC-guns. Such concepts are supposed to be an option for guns with increased performance compared to fielded systems. The advantage besides the performance consists of fast and reliable ignition as well as of the compensation of the temperature sensitivity. Modern concepts are based on high loading density (≥ 1.2 g/cm3) but only on minimum electric energy that appears to be sufficient for both ignition and control of the main combustion processes.
Conventional interior ballistics codes such as lumped parameter models or fluid dynamics based models successfully applied to many charge configurations are used to analyze the main propulsion features of such ETC-concepts. The interesting part is that the computational results of the codes compare fairly well for systems in the whole range of loading densities as long as the spatial pressure gradient shows a conventional shape. However there exist ETC-concepts under current investigation with non-conventional pressure gradient. For these cases the computational results differ significantly. The differences can be explained. The consequences with respect to the performance aire amazing. Another essential issue is coupled to the sensitivity of systems with high loading density. The computational results show how the sensitivity is affected by the charge design.
