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

RÉSUMÉ

Combustion tests of gaseous oxygen atomized sprays of gelled RP-1 propellant with ultra-fine aluminum powder (Alex® powder) were performed in a rocket engine. The addition of aluminum particles to gelled RP-1 propellant has the potential to significantly increase the heat of reaction over RP-1 alone due to the high volumetric energy release of the aluminum. Previous studies of gelled RP-1 propellant with aluminum have yielded low combustion efficiencies. This may have been the result of incomplete combustion due to the aluminum particles being too large. Alex® particles with an average size of 100 nm are formed by exploding aluminum wires. The use of these nano-sized particles can, theoretically, lead to more complete combustion, and thus, lead to performance increases such as higher flame temperature, increased specific impulse, and greater c* combustion efficiency. The gel propellants were introduced through a coaxial injector and gaseous oxygen was used to atomize the gel. The engine operating conditions were as follows: chamber pressures ranging from 1−2.8 MPa (150−400 psia), gel propellant mass flow rates ranging from 8−40 g/s, gaseous oxygen mass flow rates ranging from 14−27 g/s, and O/F ratios ranging from 0.5−3.1. The percentage of Alex® particles in the gelled RP-1 propellant ranged from 0−55% by weight. The c* combustion efficiency was found to range from 70−99%. Test results indicate that the addition of Alex® particles to gelled RP-1 propellant increases not only the density specific impulse, but also the c* combustion efficiency over gelled non-aluminized RP-1 propellant. Results show that among the three formulations, the 5-wt% Alex gel appears to be the best in terms of range of c* efficiencies and the least data scatter.
