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

The dispersion of shot is an important performance index of a base bleed projectile. Correctly estimating the characteristic quantity of dispersion of the base bleed projectile, effective reducing the dispersion of the projectile, reasonably determining the dispersion index are problems of great concern for projectile designers and ballisticians.
In this paper, the dispersion of the base bleed projectile has been estimated, and the methods for reducing the influence of nutation and the drag dispersion with base bleeding and the highaltitude wind on the dispersion of projectile have been introduced. Then, the effects of various factors on the dispersion of projectile have been analyzed, and it is pointed out that the initial velocity dispersion, nutation dispersion, gusty wind and drag dispersion with base bleeding are the main factors affecting dispersion of projectile. Because the drag of base bleed projectile is so weak that the effect of the drag dispersion on over all-dispersion will be more sensitive. Factors affecting dispersion of the base drag with base bleeding and the influence of the dispersion of ignition time on over all-dispersion have been discussed. The methods of reducing dispersion have been stated, and the methods of determining the index of dispersion and of making reasonable distribution have been demonstrated. The firing test have proved that the theory and methods given in this paper are verified.
