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

Краткое описание

Ballistic properties of solid propellants play an important role in the performance of the solid propellant rocket motors. Since the solid propellant rocket motors are generally used for military purposes, detailed characterization of the propellant ignition and combustion behavior has to be conducted in the development of a solid propellant. In this study, a specific Ammonium Perchlorate/Hydroxyl Terminated Polybutadiene (AP/HTPB) composite solid propellant was examined to obtain the ignition delay times as a function of heat flux and pressure. This study is a part of some experiments which were conducted to investigate the ballistic properties of propellants such as steady-state linear burning rates, temperature sensitivity, and pressure deflagration limit. Ignition tests were conducted at three different average laser energy fluxes of 40, 80, and 120 W/cm2. The laser produces a beam profile with a diameter of around 3.5 mm at the propellant surface. An LED light operated by the signal from the shutter was superimposed adjacent to the image of the propellant sample to indicate the onset and the duration of the laser energy input. Three parameters were deduced from the video camera records such as initial gas evolution time (tGE), first light emission time (tLE), and onset of self-sustained combustion (tIGN). Go/no-go criterion of the propellant was also extracted.
