Dynamic stability of bombs and projectiles

Abstract

The four chapters comprising pages 1 to 123, inclusive, report were previously released in limited distribution with desigtions and dates as follows: Chapter I, CIT/JPC 4, January 2, 1943 Chapter II, CIT/JPC 5, January 2, 1943 Chapter III, CIT/JPC 6, January 2, 1943 Chapter IV, CIT/JPC 11, May 26, 1943 Chapters I and II were prepared as of July 1, 1942, Chapter III as of, September 1, 1942, and Chapter IV as of the publication date. The text is herewith reproduced from the original vellum copy by the photo-offset process, with mathematical notation in the author's hand. The references listed at the end of Chapter IV were originally contained in CIT/JPC 11 and since this list includes all references cited in JPC 4, 5, and 6, the lists originally contained in these reports are here omitted. The study as planned was intended to cover all aspects of the dynamic stability problems involved in solids moving through fluids. The chapters contained herein only partially cover the general subject. The results presented are immediately applicable to the ballistics of aerial bombs or the air trajectory of torpedoes. They also apply to the underwater ballistics of depth bombs and the underwater behavior of torpedoes in that phase of the trajectory where cavitation is absent.
