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

摘要

In this paper, burning rates, temperature and OH concentration profiles of pure RDX and pseudo propellants containing RDX with CAB binder having 8, 11, and 14 percent by weight were determined. UV/Visible absorption spectroscopy was used as the diagnostic technique to determine the gas-phase temperature and OH species concentration profiles. The deduced final flame temperatures from absorption measurements are 3062 K for pure RDX, 2990 K for RDX/CAB (92/8%), 2806 K for RDX/CAB (89/11%), and 2742 K for RDX/CAB (86/14%) at 0.45 MPa. In order to examine the pressure dependency of final flame temperatures and OH mole fractions, absorption measurements were also conducted at 0.17 and 0.79 MPa for pure RDX. The results showed that pure RDX has a final flame temperature of around 2950 K at 0.17 MPa and 3220 K at 0.79 MPa. The deduced final flame temperatures are in good agreement with equilibrium calculations. The deduced OH concentrations from absorption measurements are lower than equilibrium calculations due to the non-one-dimensionality of the flame causing uncertainties in the effective pathlength of the light beam. During the tests, it was observed that there was no multistage flame structure for both pure RDX and pseudo propellants with RDX/CAB mixtures. Thermocouple measurements for pure RDX indicated that the surface temperature is about 600 K at 0.17 MPa and 675 K at 0.79 MPa.
