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

ABSTRACT

Spontaneous radiant energy feedback measurements in a radial burning non-aluminized AP composite-propellant grain obtained with a micro-calorimeter, are reported in this paper. The experimental techniques developed for the measurements are described. Measurements performed at 3 different pressures show an increase in the radiant heat flux with pressure. A wavelength averaged propellant extinction factor was measured to evaluate the radiant heat flux opacity of the solid propellant grain. An extinction factor of about 3.7 cm−1 was determined. Finally, the steady burning rate was measured using two different experimental techniques. The first one utilized a video-frame recording system and the second one involved the analysis of the pressure vs. time plots for the burning propellant This experimental work is the first step in a series of studies, the final goal of which is to develop a procedure for the evaluation of the magnitude of the radiant energy feedback from the burning propellant surface and its effects on both the propellant burning rate and the scale factor.
