Recent developments of experiments,mechanism and modeling research on the plasma ignition of propellants were introduced. The feasibility of plasma ignition technology in the application of insensitive high energy propellants was discussed. The concepts,frames,keynotes and related research tactics in plasma ignition of insensitive high energy propellants were proposed. The plasma ignition research of insensitive high energy propellants should benefit from the research fruits of plasma ignition in electrothermal chemical gun. Based on the interaction between the plasma and special formulations in insensitive high energy propellants,the plasma energy output power adjustment and structural design of igniter can be carried out.
