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

RESUMO

Advanced gel propulsion systems are being designed and developed for use in volume-limited space vehicles and advanced missile interceptors where safety, energy management, high performance, and efficient packing are the main concerns. Gelled propellants utilized in such a propulsion device are very delicately balanced systems and exhibit a complex ignition, combustion, and rheological behavior. The ignition and combustion characteristics of such heterogeneous systems have to be precisely understood to design a suitable injector and combustion chamber of the rocket motor to achieve a desired level of performance and combustion efficiency. An experimental investigation on ignition and combustion characteristics of UDMH gelled with high-substitution methyl cellulose as fuel and RFNA as oxidant has been carried out with and without metal additives, using a conventional ignition-delay tester and a customized twin-jet combustor. The ignition and combustion behavior of the gelled systems injected through a single-element injector has also been investigated. Preignition, ignition, and postignition temperature profiles close to the impingement point of the respective jets in a specially designed twin-jet combustor have been recorded using a suitable thermocouple and precision recording system. It has been observed that gels show lower ignition delay than the parent hypergolic system, however, a marginal increase is recorded in the case of metalized systems. The rheological characterization of the fuel gel has been conducted in a wide range of shear rate (10−2−106 s−1) and it has been found to be thixotropic in nature with viscosity values drastically falling with shear rate.
