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 hybrid rocket system is a promising next-generation space propulsion system owing to its low cost, high safety ability, and green characteristics. Conventional hybrid rocket systems have difficulty implementing large thrust motors owing to the low fuel regression rate. Studies regarding high regression rates of hybrid rocket fuel have been necessary for large motor designs. The high regression rate of low melting point fuels was confirmed in static firing tests by several researchers, where small droplets of the liquefied fuel were observed popping out from the burning surface using a slab motor in atmospheric conditions. However, the mechanism for the generation of small droplets from the fuel surface is unknown. The behavior of droplets under high pressure needs to be observed for a more thorough understanding of the combustion mechanism. In this study, a slab motor was prepared. Four fuel types, polymethyl methacrylate (PMMA), glycidyl azide polymer (GAP) mixture polyethylene glycol (PEG) fuel (GP fuel), WAX, and low melting point thermoplastics fuel (LT fuel), were selected as inert, high energy material, and low melting point fuels. The Katazen Corporation developed special LTs for this study to lower the melting point to a hot water temperature range. Visible light was eliminated to easily observe the surface behavior. An infrared filter was employed that allowed a wavelength of 760 nm or above to penetrate. No droplets were observed in the PMMA and GAP mixture PEG fuel combustion tests or during the Wax and LT fuel combustion tests conducted at 0.1 and 2 MPa.
