Activities of the Deflagration-to-Detonation Transition Project. Quarterly report, September--November 1978
- ed.
A project has been initiated to address deflagration-to-detonation (DDT) transition as it applies to low voltage detonators. Studies with the relatively new DDT explosive CP are underway in the areas of physics of DDT, compatibility, and component development. In addition, materials studies are oriented towards the development of a similar, but safer, DDT explosive. The objective of the physics studies is to establish a modeling capability; a program to achieve this end has been outlined. Preliminary experiments have shown that ignition and deflagration can be observed optically through headers. Materials studies have commenced on (a) coating CP with secondary explosives and (b) synthesizing and evaluating compounds similar to CP. Continuing compatibility work has shown an absence of evidence of corrosive attack in Mini-Dets examined under optical microscopy. Activities on two CP-loaded detonators, the MC3423 and the MC3450, are described. For the first time, CP-loaded devices have been designed which achieve a 1 amp, 1 watt, 5 minute no-fire condition, while also achieving the all-fire conditions. Test devices for each application have yielded satisfactory output. Function times of approx. 10 ..mu..s have been obtained with a Velonix bridgewire pulse of 15mJ.
