Flyer plate explosive
WebThe flyer-plate components and the explosive pellets were cooled to the desired temperature by immersing them in dry ice (194/sup 0/K) or liquid nitrogen (77/sup 0/K). Two firing systems were used. In one system a 0.6..mu..F capacitor supplies energy to a 0.635 x 0.011mm bridgefoil. In the other system a 6.0..mu..F capacitor supplies energy to ... WebThe main difference between these two processes lies in the driving source of force generation such as electromagnetic force to propel the flyer plate in case of MPW and finite quantity of high explosive material to propel the flyer plate in case of EXW process [3,15]. The explosive materials used in EXW are difficult to procure and control ...
