Study on the Structure of the Hemispherical Booster Pellet

Aim A kind of new structure of booster pellet is studied, which can be sure to initiate large main charge explosive under the condition of less explosive quantity. Methods This paper analyses the characteristics of insensitive explosives. In the light of the corner effect theory and relatied detonation theories, the structure of hemispherical booster pellet was designed and its superiority was tested and verified. Results\ Under the same initiating conditions, the hemispherical booster pellet has a stronger initiating capacity than the cylindrical booster pellet of same quantity. Conclusion\ The new structure of hemispherical booster pellet has obvious effects on increasing initiating capacity of booster pellet and on decreasing explosive quantity. It has the significance of initiating reliably insensitive large main explosive charge.
