Opis:
The appearance of insensitive main charges has created new requirements in the booster pellets of the detonation train, specifically, the output of the booster pellet must be strong enough to initiate the insensitive main charge. Traditional cylindrical booster pellets have great difficulty in meeting the demands of the insensitive main charge for reliable detonation. A four-point-synchronous explosive circuit and an eight-point-synchronous explosive circuit were designed to initiate two booster pellets, designed on the basis of shock initiation theory and effective charge theory, as well as the shaped charge effect theory. The results show that booster pellet 1 and booster pellet 2, under multi-point-synchronous explosive circuits, can initiate standard main charge pellets with less explosive mass than an ordinary cylindrical booster pellet. The initiation capacity of booster pellet 2 is better than that of booster pellet 1.

Opis:
The insensitive main charge explosive is becoming an important part of modern weapon development. Insensitive main charge explosives generally have a high critical initiation pressure. The detonation pressure of a traditional cylindrical booster pellet is constant at a specific density and consequently has insufficient energy output to reliably initiate an insensitive main charge explosive. To ensure that this requirement could be achieved, the conical ring booster pellet was designed and optimized. Eight-point-synchronous explosive circuits were designed as appropriate to the sizes of the four booster pellets. The initiation processes of the four conical booster pellets equipped with the eight-point circuit were simulated using ANSYS/LY-DYNA software. The experimental measurements were performed in order to test the initiation capacities of these conical booster pellets. The results demonstrated that their initiation capacities are much better than the initiation capacity of a cylindrical booster pellet. The optimum size of the conical ring booster pellet is when the ratio of the inner to the upper diameter is 0.52, the ratio of the inner to the lower diameter is 0.44, and the ratio of the height to the lower diameter is 0.50.

Opis:
Insensitive munitions improve the survivability of both weapons and their associated platforms. All weapon systems contain an explosive train which needs to meet the insensitive munitions criteria but also to reliably initiate the main charge explosive. The traditional cylindrical booster pellet has insufficient energy output to reliably initiate an insensitive main charge explosive. To ensure that this requirement can be achieved, a new highly effective booster charge structure was designed. New booster pellets of four different sizes were investigated by numerical simulation and the one with the most powerful output was selected for experimental study. The results show that the new booster pellet has more initiation capacity than a cylindrical booster pellet with the same mass and pressed density. The convergence pressure of the new booster pellet is much higher than that of a cylindrical booster pellet with the same density.
