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 a continuing investigation of the chemical composition of the dark zones of double-base and nitramine solid propellants, additional multichannel infrared absorption experiments have been performed. The experiment has been improved by the addition of mirrors on a portion of the chamber windows effecting a "triple-pass" of the beam through the sample region. Overtone absorptions for CO at 2.3 μm and N2O at 3.9 μm were measured and analyzed to determine absolute concentration and temperature. Least-squares fitting routines using the HITRAN database were developed and used for this analysis. The solid propellants, JA2 and XM39, were probed under steady-state combustion conditions in a nitrogen environment of 1.0−1.3 MPa pressure. CO is a major gas species in these propellant flames and concentrations of about 0.35 and 0.12 mole fraction were obtained in the dark zones of JA2 and XM39, respectively. Small absorption signals were found in the spectral region appropriate for N2O and an upper limit of 0.02 mole fraction was determined for XM39. No absorption in this region was observed for JA2. These results are in qualitative agreement with published values.
