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

要約

The experimental study of solid propellant combustion has been improved by using Laser Doppler Anemometry (LDA), which is able to measure the velocity of the gases coming from the burning propellant surface. This technique provides data which can be used to define the combustion processes because the gas velocity strongly depends on burning rate. [1] Thus, every combustion transient can also be studied analyzing the time evolution of the gas velocity. Despite the hostility of the medium (hot gas with solid particles) LDA actually finds applications ranging from basic studies on propellants combustion to real propulsion systems. [2] This diagnostic provides useful information and an accurate picture of the flame structure. It has been used to test double base (DB) propellants under steady state conditions in the pressure range from 15 to 40 atm and AP composite propellants from the Pressure Deflagration Limit (PDL) up to 5 atm. Self-sustained oscillatory burning, occurring at sub-atmospheric pressure for AP composite propellants, has also been investigated. By using a modulated carbon dioxide laser, and the LDA apparatus, the frequency response of an AP propellant, burning in the sub-atmospheric pressure range, has been studied.
