Abstract : The principles of the proposed soft ignition system have been defined and studied and are based on a laser/fiber optic sub-system to achieve simultaneous multiple point ignition at several axial and radial positions within the propelling charge. Effective designs for laser sensitive primers were developed and demonstrated. Ignition delay and the resultant jitter were measured as a function of such variables as igniter mass and case material, etc. The resultant ignition delay of these designs was determined to be largely a function of confinement and case material specifications. The minimum ignition delay measured was 120 microsecs and ignition jitter can be reduced to two percent by judicious application of the information derived from the present effort. The degree of simultaneity will ultimately be limited by the uniformity of the manufacturing process and the materials employed. The designs developed and demonstrated in this work define the basic primer performance and the intrinsic delay.
