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

ABSTRACT

The goal of this paper is to show significant influence of ignition conditions on subsequent combustion of a condensed propellant and on the pressure diagram of combustion chamber. Emphasis is placed on the effect of accelerated combustion (AC-effect) after ignition in a high pressure closed bomb and in a chamber with moving piston. An analysis of such typical problems is carried out using an original phenomenological theory. Intermediate asymptotic solutions for the temperature and composition of combustion products as well as for the transitional combustion rate are presented. These asymptotic solutions show how the ignition conditions influence the subsequent unsteady combustion and pressure diagram in a high pressure chamber. The AC-effect of propellant surface layers and its dependence on ignition characteristics is demonstrated. A modification of Drozdov’s solution of the basic problem of gun interior ballistics has been obtained taking into account the AC-effect. It is shown that AC-effect can be responsible for the anomalous increasing of pressure-peak with decreasing of initial temperature of propellant charge in a gun-chamber.
