Abstract:

Cubic form-functions in burning surface regression distance are derived and compiled for granulations that are used in current U.S.A., U.K. and Australian ammunition. Functions for specific inhibition of grain surface, sliver burn for multi-perforated grains, and unequal webs in seven perforated grains, are included. The functions are of general use in propellant grain design, closed-chamber and interior ballistic computations. Their resolution into igniter and propellant segment contributions as a function of grain surface regression, facilitates studies on multi-granular, multi-propellant charges, mortar charges, deterred grains, programmed or non-isochronous ignition, and the design of specific, or maximum progressivity granulations.
