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

SINOPSIS

During the decade of the 1980s, a number of people died manufacturing and mission suitability testing Explosive Class 1.3 solid propellants. During the same time frame no one was fatally injured in the United States in Explosive Class 1.1 solid propellant incidents. This incongruence of fatal injury incidents with the "explosively safer" Class 1.3 propellants rather than with Class 1.1 propellants was due to the relative burning rates of Class 1.1 and Class 1.3 propellants at low pressures of one atmosphere or slightly higher. Explosive safety problems with Class 1.3 propellants can also occur in the high pressure regimes with rapid acceleratory burn rates above the so called burn rate exponent slope break for ammonium perchlorate oxidized compositions. An enormous explosive threat can occur when large Class 1.3 solid propellant motors used for space launches experience early flight failures and motors or motor fragments crash to earth at high velocities. When propellant quantities are in the range of roughly 50 to nearly 500 metric tons per booster motor, there is a great blast potential. Preliminary screening of a few booster compositions in low and ultrahigh pressure regimes has produced hope that careful selection of combustion traits and propellant materials might substantially improve large rocket motor safety.
