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

In order to try and understand the behavior of a hydroxyl-terminated polyether (HTPE) propellant in slow cook-off and to compare it with a similar HTPB (hydroxyl-terminated polybutadiene)-based composition, a co-polyether pre-polymer was synthesized. Two kinds of HTPE composite propellant plasticized with n-BuNENA, containing either ammonium perchlorate (AP) as oxidant or a mixture of AP and phase-stabilized ammonium nitrate (PSAN) were manufactured. Antioxidants were not included in the formulations. The two kinds of HTPE propellant were cured inside small-scale slow cook-off test vehicles (SCTV). The SCVT were heated slowly in accordance with the STANAG 4382 criteria for slow cook-off. The thermal decomposition behavior of HTPE and HTPB binder networks, gumstocks, and propellant samples were also investigated by differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) spectroscopy, and size exclusion chromatography (SEC). Both kinds of HTPE propellant behaved in a different way to that reported in previous studies, although for HTPE propellants containing only AP as oxidizer, no published information has been found. In fact, the ignition temperature for the HTPE/AP/n-BuNENA and HTPE/PSAN/n-BuNENA compositions were observed at around 180°C and 215°C, respectively, and the HTPE propellant composition containing PSAN as oxidizer gave a more violent response than the HTPB composition. It was observed that while the HTPB propellant became hard and brittle during slow heating, both kinds of HTPE propellant became softer, with the sample containing PSAN as co-oxidizer having the greatest degree of softness. It is believed that the softening and even liquefaction of the organic phase in HTPE propellants has an important influence on the slow cook-off response, especially if the surface area at the ignition time is taken into account as a factor in the response to slow cook-off.
