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

RESUMO

An investigation of polyNIMMO's potential, as both binder and oxidiser, in a high energy smokeless solid fuel gas generator propellant comprised part of a UK ramrocket development programme. The benchmark trial showed polyNIMMO's burn rate was considerably lower than GAP, or polyGLYN. The advantages and disadvantages of various binary mixtures of polyNIMMO with fuels, oxidisers, plasticisers and bum rate catalysts are discussed. The conclusions drawn from this study were applied to multiple component polyNIMMO formulations, with volumetric heat values of up to 32200 MJ/m3 (∼500 Btu/in3). Difficulties with ignitability of fuel-rich systems were observed. Comparison of the chamber temperature (which varied, significantly, with pressure) with the burn rate proved to be a more suitable method for assessment of ignitability than the formulations temperature of ignition. The relationship observed between the calculated chamber temperature and experimental burn rate will be discussed in greater detail. This work has shown that the smokeless fuel-rich polyNIMMO gas generator compositions examined possess the basic characteristics required for an air-breathing radial-burner motor configuration. Effort is currently focused on achieving a smokeless fuel-rich formulation (≈32200 MJ/m3) possessing a high pressure exponent (∼0.5-0.7) with a slow, stable, bum rate (∼0.7 mm/s) at low pressure (<3 MPa).
