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

RÉSUMÉ

The development of a transient thermal conductivity apparatus specifically for ablative materials is presented. This innovative apparatus is capable of determining thermal conductivity of materials over the temperature range of 340–1200 K, covering the pyrolytic stage of the composite material. The target specifications of the apparatus are the measurement of thermal conductivity in the range of 0.1–5.0 W · m-1 · K-1 using specimen thickness in the range of 7–25 mm. This is achieved by using a new design of a symmetric heater-specimen assembly, creating an adiabatic state along its centerline. The temperature-controlled system is sustained in a closed chamber, capable of introducing specific gases, enabling tests under a wide range of environmental conditions. Comparison of test results with available data of known materials shows good agreement. Testing of different ablative materials reveals similarities and differences associated with specific compositions and processing features. These results can support modeling of ablative materials for various applications such as solid rocket nozzle throat.
