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: 0.2 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: 0.3 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: 0.00004 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: 0.08 SJR: 0.153 SNIP: 0.178 CiteScore™:: 1 H-Index: 12

ABSTRACT

Determination of the weight (or thickness) of the heat protection of high-speed aircraft structural elements at the design stage has always been very urgent, since it defines an essential design parameter, i.e., the weight of the aircraft. Estimation of the thickness of the aircraft heat protection in correlation with the thermal and physical characteristics (TPCs) allows minimizing the thickness and, hence, the heat protection weight. In this work, the analytical solution of the heat conduction problem and the temperature restrictions for metal structure are used to develop methods for estimating the optimal thickness of the heat protective layers depending on the thermal conductivity, the final heating time and the ratio of the metal structure limiting temperature to the temperature on the outer boundary, and to build nomograms of the dependence of heat protection thickness on the above parameters. These nomograms can be used to determine the optimal heat protection thickness.
