The technology of ignition and flamespreading is one of key technology of charge design in large caliber guns. The simulation test for ignition and flamespreding in guns is presented in this paper. The characteristics of ignition and flamespreading for different charge constructions are studied in detail. The influence of power bags, stick propellants and low velocity detonation (LVD) on the performance of ignition and flamespreading is given. The experimental results show that, the influence of flamespreading velocity in axial direction on p～t curves and ignition holes breaking is stronger, a new type of ignitor-LVD is effective for improving the performance of ignition and flamespreading. The research result in this paper is of great value for the design of ignition and flamespreading in model charge.
