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

RÉSUMÉ

In the case of center-perforated composite solid propellant grains, the radial linear burning rate often depends on web location. In many cases, the burning rate of the propellant in the middle of the web is highest along the radial direction. This distribution of the linear burning rate along the radial direction is called a midweb anomaly or hump effect. This phenomenon was researched in the 1980s in depth with many studies disclosed the mechanisms and causes. Recently, the spatial burning rate variation was measured directly with an ultrasonic device. Many studies have explained that oxidizer [ammonium perchlorate (AP)] particle orientation affects the magnitude of the linear burning rate. In addition, some studies showed that the burning rate anomaly depends on the burning direction. This phenomenon is practically important for the prediction of pressure-time history of a rocket motor with high accuracy. In this study, the midweb anomaly on a small center-perforated motor was investigated. The formulations of the sample propellants were similar to practical propellants. As a result of the motor firing test, pressure hump effect was measured. The burning rate anomaly along the web was estimated by the pressure hump effect and was dependent on the slurry casting process. In order to determine the directivity of the burning rate, it was measured along the motor
