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

ABSTRACT

The advantages and disadvantages of gel propellants and gel propulsion systems are discussed. The preparation of some gel fuels is described using JET A-1 (JP-8) as basic fuel for gelation. A Cowles blade type dissolver apparatus was used for the preparation of the gels using inorganic (fumed silica) and organic (Castor oil derivatives and aluminum octanoate) gelators. The conditions for optimal production results were investigated in several test series. The main production parameters are dissolver disk rotational speed, dissolver diameter, gellant particle size, gellant content, container dimensions, and temperature history of gelation.
Several methods for characterization of gel stability and viscosity behavior are discussed, and the results are presented. Gel stability was investigated in conventional and optical centrifuge tests at accelerations up to 2,500 g, and it turned out that all the gels were stable below accelerations of 100 g. Viscosity measurements were performed using rotational cone and plate viscosimeters. The results could be fitted to existing viscosity laws and were used to compute the pressure loss in gel rocket injectors and supply lines. All gels showed strong shear-thinning behavior.
