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

ABSTRAKT

In order to understand the behavior of internal insulators in solid rocket motors (SRMs), it is necessary to observe them under a well-characterized thermal environment. While it is most important to know the total heat flux to the insulator, it is also valuable to know what fraction of that flux is due to its separate radiative and convective components, as each mode is governed by fundamentally different physics and, thus, affects the insulator differently. Therefore, a radiometer has been developed to measure the purely radiative component of heat flux in an SRM. In this design, a Schmidt−Boelter-type heat flux sensor is isolated from the convective flow of SRM combustion products by a sapphire window, which is mounted in a recess in the wall of the SRM. Condensed-phase particles generated by the combustion of metalized solid propellant are prevented from striking and adhering to the window by two jets of cold inert gas: one injected at an oblique angle to the combustion product flow and another injected normal to the window. The radiometer was installed in a laboratory-scale SRM burning AP/Al/PBAN composite propellant for a series of test firings, the results of which demonstrated that the inert gas jets are capable of maintaining a clean window throughout a 20 s firing duration. The radiation measurements obtained from these firings exhibit good repeatability and physically reasonable temporal behavior. Therefore, it is concluded that this radiometer design is robust and capable of providing accurate measurements of thermal radiation fluxes within an SRM.
