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

The combustion of boron containing propellants, based on AP/GAP and AP/HMX/GAP formulations, have been investigated by applying fast spectroscopic, pyrometric and photographic techniques. The propellants burn at a rate of 17mm/s at 5 MPa. Addition of an iron oxide catalyst increased the rate to 20 mm/s at the same pressure. The determined average pressure exponents are 0.66 without and 0.57 with iron oxide as catalyst. At pressures higher than 5 MPa, a strong decrease in the exponent is observed. The reaction zones show high particle concentrations with temperatures from 1500 to 2000 K, varying with the nitrogen pressure. Reacting with air, the particle temperatures increase close to the evaporation temperature (2200 K) of boron oxide. The reaction of boron with oxygen is proved by the results of spectroscopic data. Considering an application in a ducted rocket, the boron is heated to the desired reaction temperature.
