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

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

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
