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 addition of nano-sized energetic materials, such as aluminum and boron, has been shown to increase the mass-burning rates of solid fuels. Previous results showed that the addition of 13 wt% Silberline® aluminum flakes to HTPB-based solid fuels increased linear regression rates by as much as 60%. When similar fuel formulations were tested in a larger (∼3 times the port diameter) hybrid rocket motor the measured regression rates were nearly identical to those of pure HTPB solid fuels. SEM/EDS analysis was conducted to indicate the reason behind this phenomenon. In contrast, the addition of the same wt% of Silberline® flakes to paraffin-based solid fuels does show a significant increase (∼30%) over baseline paraffin solid fuels. The differences in particle entrainment mechanisms for these two types of fuels were attributed to the trend of burning-rate augmentation. Waterfall analyses of pressure-time signals were utilized to study the inherent low-frequency instability of hybrid rockets. Comparisons are made to a universal frequency-scaling formula proposed in the literature, showing agreement to within 25%. To understand the instantaneous mass-burning behavior, a real-time X-ray radiography system is utilized to image the solid fuel surface during combustion testing. Results for both HTPB-based and paraffin-based solid fuel formulations are described. Traditionally, average solid fuel regression rates are correlated to the average oxidizer mass flux by a power-law curve fit. However, instantaneous fuel surface burning behavior does not exhibit the power-law behavior when correlated to the instantaneous oxidizer mass flux.
