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

SINOPSIS

The objectives of this work are to characterize the composite solid propellants developed by FAMAE and to study the chemical compatibility between the components of a specific rocket engine. The Arrhenius kinetic constants for the thermally unstable materials were taken from ASTM E-698. STANAG 4147 was used in the determination of compatibilities of explosives to each other and to other materials, and in the qualitative analysis of the energy curves. This method was proposed by METTLER Toledo company. Differential Scanning Calorimetry (DSC) was utilized for thermal analysis. Experiments were conducted to characterize the rubbery composite propellants by determining their activation energies, frequency factors, the pre-exponential constants of reaction, their average lifetimes, and their percentages of conversion at given temperatures. Also, their caloric capacities were determined as a function of temperature. Compatibility tests were also performed, for different components used in the rocket engine. Aging of the rubbery composite propellant material was studied by artificial heating to 65°C for periods of 30, 60, and 90 days. The results are given in the paper.
