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

The chemical aging mechanism of minimum smoke or nitrate ester propellants loosely consists of the decomposition of the energetic plasticizer leading to the eventual production of various gasses to include NOx, and CO2. When the rate of production of these gasses exceeds the rate of diffusion to propellant-free surfaces, gas accumulation in intermolecular free space can lead to propellant cracking and/or autocatalytic ignition of the propellant grain. To limit the rate of production of these gases and to extend the useful service life of these propellant systems, stabilizers such as N-methyl-4-nitroaniline or 2-nitro-diphenylamine are added to react with the intermediate decomposition species to produce a thermally stable and nongaseous compound. Service life monitoring then consists of destructive testing of samples of motors of various ages from the population in question whereby the rate of stabilizer depletion is measured and the remaining service life is projected based on the estimated time for the stabilizer level to fall below an accepted minimum level. This paper presents a nondestructive approach and preliminary results for the use of carbon nanotube gas sensors for the health monitoring of nitrate ester propellants. Gas sensors placed in the bore or canister of individual motors will monitor the partial pressure and rate of production of decomposition gas products. The rate of evolution of NOx is correlated to the remaining stabilizer in the propellant.
