CP DDT detonators. I. Design sensitivity study
A standard CP detonator design has been used to study a variety of design parameters including test temperature, closure disk thicknes, powder column diameter, transition column diameter, powder column confinement, igniter charge holder material, bridgewire diameter, fire pulse energy, fire pulse duration and fire pulse current. The data indicated a minimum function time for such detonators of approximately 7 ..mu..s, which is limited by the deflagration-to-detonation (DDT) process. DDT can be achieved in the presence of some venting but is inhibited by charge holder materials which provide the poor confinement. Increasing the powder column diameter or the transition column diameter results in longer function times. With increasing temperature, output increases and function time decreases.
