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

JA2 is a commonly used gun propellant for various weapon systems. Knowledge of its combustion behavior is useful for system design application. The burn rate of JA2 propellant was determined as a function of pressure, 0.69 ≤ p ≤ 41.4 MPa (100 ≤ p ≤ 6,000 psi), and initial temperature, 25°C ≤ Ti ≤ 60°C. Burn rate plot shows slope breaks at 6.9 MPa (1,000 psi) and 4.5 MPa (650 psi) for the initial temperatures of 25°C and 60°C, respectively. At high pressures, P > 40 MPa (6,000 psi), measured burn rates were found to agree with the Army's closed bomb data. The steady-state burn rates also agreed with the instantaneous burn rates obtained from X-ray radiography measurement conducted at various chamber pressurization rates. The burning surface temperature and temperature sensitivity (σp) were also deduced. The rapid decay of σp with an increase in pressure for p < 20 MPa and extremely low values of σp at pressures greater than 20 MPa explains the lack of dynamic burning of JA2 propellant.
