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

Bristol manufactures several small solid propellant rocket motors using a composite HTPB/AP based propellant system. Most Bristol rocket motors developed prior to 1990 used an internal insulation system consisting of an asbestos-filled roll-form butadiene (RF/B) case insulation material, with an aluminum liner between the propellant and the insulation. Due to health and safety regulations, processing of asbestos containing insulation materials is no longer permissible. The RF/B insulation system has been replaced with alternate insulation systems which use a Bristol proprietary carbon-filled (CF/P) liner to interface with the propellant. The CF/P liner uses the same polymer system as the propellant, and provides limited insulating capabilities as well as promoting case bonding of the propellant. Motors using the CF/P liner system have shown an augmentation in the propellant burning rate prior to motor tail-off compared to their previous RF/B insulated versions. The performance changes are attributed to a localized augmentation of the propellant burning rate adjacent to the CF/P liner interface. This paper will discuss potential mechanisms for the burning rate augmentation effect, and describes the results of testing and analyses performed to evaluate the phenomenon.
