ANALYSIS OF PROPELLANT IGNITION, AND ITS APPLICATION TO MOTOR INITIATION

Abstract

A model of solid propellant ignition is given in order to relate igniter energy output to motor ignition. Difficulties inherent in the nonlinear partial differential equations of heat and mass diffusion describing the ignition system prevent the model from being completely analytical. However, certain results are derived from the equations, and when combined with arc-image furnace ignitability data, a reasonably coherent view of the process is obtained. Numerous examples of ignitability data are given. Analysis of heat and mass transfer from igniter to motor grain is given for the case of propellant-type igniter. This analysis, along with the pertinent ignitability data, is applied to ignition of the 2nd stage Minuteman motor.
