Ignition propagating

The examination of this model and results of numerical solutions indicate that ignition propagation is determined by the absolute value and variation of heat transfer along the surface of the grain, both before and after the first instant of ignition on the grain surface. Therefore, the important variables are (1) igniter flow rate, (2) port diameter, (3) gas temperature, (4) gas composition, and (5) motor pressure.

Once a portion of a pyrotechnic composition has been ignited, propagation (burning throughout) is not guaranteed.
