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

ABSTRACT

Ultrasonic measurements show a very good quality/cost ratio and are a non-intrusive technique that supplies the thickness variation and thermal behaviour of different materials inside the motor. They provide a comprehensive amount of data concerning the internal behaviour of the motor, such as instantaneous behaviour of internal thermal insulation wherever in the motor and instantaneous ballistic behaviour of the propellant grain during the test. This study deals particularly with 'Great-depth' transducers, which allow measurement of propellant up to 1-m thick. It covers acquisition from ignition to the end of a firing test, even on the largest motors such as ArianeV-P230 or VEGA-P80. 'Great-depth' ultrasonic measurement enables the replacement of heavy specific tests like live radiography or combustion stopped by drowning. Furthermore, it provides a large amount of live data from large-scale tests that could be included in simulation software in order to improve ballistic performance predicting. Knitline effect and edge effect, which generate local higher burning rate, are particularly tackled in this study.
