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

Hybrid rockets may present a good propulsion alternative for different missions, particularly for the emerging field of space tourism, mainly due to the safety of the motor both during development and operation. Nevertheless, for certain applications the low regression rate of conventional polymeric fuels implies too low of a thrust. In recent years, paraffin (wax)-based fuels have been investigated because of their much higher regression rate compared to that of polymeric fuels. Paraffin, however, presents relatively poor mechanical properties. The motivation of this research is to acquire data on pure paraffin (wax) and mixed paraffin- polymer (HTPB) fuels and to compare their actual energetic performance (mainly C*), regression rate, and certain mechanical properties. Polymethylmethacrylate (PMMA, Plexiglas) fuel was tested as well, as it is the most used hybrid fuel in laboratory experiments and can serve as a reference to other works. A comparison to results from the literature for similar fuels with oxygen as the oxidizer was also done to identify the influencing properties of the specific oxidizer. It was found that the regression rate of paraffin is about 5 times higher than that of PMMA (polymer). A mixed paraffin-polymer (HTPB) fuel gives a lower regression rate than pure paraffin, yet it is higher by about two- or threefold than that of PMMA. C* efficiency obtained was in the range of 80%−100%, with an average of about 90%.
