The shock gel process can be
utilized for the manufacture of spherical gun propellants. Typically,
nitrocellulose syrups which are prepared by the dissolution of nitrocellulose are
used in conjunction with gelling baths. Although the process is relatively
simple to operate there are multiple factors that play a role in the
development of the propellant size and shape distributions and the porosity of
the propellant. In this presentation some of these major factors will be
elucidated in conjunction with the results of investigations utilizing both
live propellants and inert simulants. The issue of
deterring the grain in situ will also be discussed.
