Research overview:
The cavity ignition method is a new idea of ignition method to simplify the present ignition method by the ignition motor which utilizes same material for the main feed agent and main propellant based on the basic design idea that the ignition motor main feed agent is integrated with the grain by leaving pressure vessel out and the cavity that plays the rolls of the combustion area/free volume and throat is preliminary formed at the top of it. Continued to the success in the small spherical motor DASH-DOM, it has been introduced into the redesign of the large L/D motor S-310 and the practical applicability has been proved by confirming good ignition property in the improved S-310-30 flight experiment, although some difficulty in the operation of the ignition booster was observed in the ground combustion test tools.
