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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RÉSUMÉ

This work considers the ability of a high speed supercavitating vehicle (HSSV) to maneuver. The vehicle is in the form of a body of revolution with two areas of wetting: at the nose disc cavitator with two degrees of freedom and the gliding stern. Additionally, different ways of transverse forces creation are studied. The concept of maneuver energy cost is introduced for their comparison. The HSSV degree of maneuvering (gyration) with the minimal radius of turning is considered. The properties of deformation of longitudinal and transverse cross section of the cavity shape at vehicle gyration are examined. The equations for estimation of a minimal admissible gyration radius and a maximal cavitator inclination angle avoiding the hull washing are given. The computer simulation of an arbitrary 3D motion of the supercavitating vehicle based on G.V. Logvinovich's principle of independence of unsteady supercavity section expansion allows to give the comparative analysis of effectiveness of the four strategies to control the supercavitating vehicle's maneuvering: by the rotary disc cavitator, by the vectoring thrust, by the "bank-to-turn" control and by the cavity-piercing fins (rudders) for both course and depth cases of HSSV maneuvering.
