Abstract
The present invention comprises a detonating cord of polygonal cross section having three or more substantially flat sides of substantially equal length and substantially equal included angles between each of the sides.
Claims3
A method of initiating clustered shaped charges, comprising:
- providing a plurality of shaped charges, each of said charges including a booster charge at one end thereof and a mouth at the other end thereof;
- disposing said plurality of shaped charges in at least one cluster about a center point, with said booster charges of said shaped charges pointed toward said center point of said at least one cluster and said mouths of said shaped charges are pointed substantially radially outward;
- disposing a detonating cord through said center point of said at least one cluster proximate said booster charges;
- igniting said detonating cord;
- and
- directing the explosive energy arising from the ignition in substantially equal plane energy waves against each of said booster charges.
