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

Краткое описание

As of now, the most widely used hypergolic fuels are hydrazine derivates with nitrogen tetroxide as the oxidizer. The toxicity and carcinogenic character of these substances make their handling challenging even if gelled. Therefore, there is great interest throughout the propulsion community in finding alternatives for these substances. However, despite a thorough literature review, clear selection criteria for "green" hypergols could not be found. To tackle this issue, we developed a set of key requirements and criteria for propellant selection. The major drivers were hypergolic ignitability, propellant performance, reduced toxicity, and economic factors. Then we used these criteria to carry out a screening aimed at identifying potential oxidizers, fuels, and additives. Hypergolicity was assessed by capturing ignition events of a simple drop test experiment with a high-speed camera. This setup allowed us to find a set of promising novel hypergolic propellants and to verify our screening method. Not only do liquid and gelled diamine fuels with hydrogen peroxide as the oxidizer provide 96% of the specific impulse of the monomethylhydrazine/nitrogen tetroxide propellant system, but they also feature ignition delay times on the order of 15 ms.
