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

SINOPSIS

The general fluid mechanic mechanism for flow about axisymmetric bodies (shell shapes) is reviewed, with reference to the very early experimental work (circa 1900) which resulted in determination over the subsonic−supersonic range of the drag−Mach number relationship.
A numerical example of drag component values for one type of modern shell is presented, to illustrate the major significance of the base drag component. The long range 210mm Paris gun shell of 1918 is discussed, being of interest as perhaps, an outer bound to the envelope of shell trajectories (apogee : 43 km, range 127 km).
The history of base injection studies is sketched briefly through early post−war work to the present systems. Various postulated wake flow models are discussed. Firing results for the minimum drag forebody projectile (commonly known as the ERFB projectile) are presented showing range increase with base bleed in the order of 30%.
